PLYWOOD


Plywood

╉PLYWOOD╊ Plywood as a building material is very widely used due to its many useful

properties. It is an economical, factory-produced sheet of wood with precise

dimensions that does not warp or crack with changes in atmospheric

moisture.

Ply is an engineered wood product made from three or more 'plies' or thin

sheets of wood. These are glued together to form a thicker, flat sheet. The

logs used to make plywood as a building material are prepared by steaming

or dipping in hot water. They are then fed into a lathe machine, which peels

the log into thin plies of wood. Each ply is usually between 1 and 4mm thick.

USES OF PLYWOOD AS A BUILDING MATERIAL

Plywood has a huge range of used within the construction industry. Some of

its most common uses are:

To make light partition or external walls

To make formwork, or a mould for wet concrete

To make furniture, especially cupboards, kitchen cabinets, and office

tables

As part of flooring systems

For packaging

To make light doors and shutters

HOW PLY IS MADE

Plywood consists of the face, core, and back. The face is the surface that is visible after

installation, while the core lies between the face and back. Thin layers of wood veneers are

glued together with a strong adhesive. This is mainly a phenol or urea formaldehyde resin.

Each layer is oriented with its grain perpendicular to the adjacent layer. Plywood as a

building material is generally formed into large sheets. It may also be curved for use in

ceilings, aircraft, or ship building.


Plywood

WHICH WOOD IS PLY MADE OF?

Plywood is manufactured from softwood, hardwood, or both. The hardwoods used are ash,

maple, oak, and mahogany.Douglas fir is the most popular softwood for making plywood,

although pine, redwood, and cedar are common. Composite plywood can also be

engineered with a core of solid timber pieces or particleboard, with a wood veneer for the

face and back. Composite plywood is preferable when thick sheets are required.

Additional materials can be added to the face and back veneers to improve durability.

These include plastic, resin-impregnated paper, fabric, Formica, or even metal. These are

added as a thin outer layer to resist moisture, abrasion and corrosion. They also facilitate

better binding of paint and dyes.

PROPERTIES

High Strength: Plywood has the structural strength of the wood it is made from. This is in

addition to the properties obtained from its laminated design. The grains of each veneer

are laid at 90 degree angles to each other. This makes the whole sheet resistant to splitting,

especially when nailed at the edges. It also gives the whole sheet uniform strength for

increased stability. Furthermore, plywood has a higher strength to weight ratio as

compared to cut lumber. This makes it ideal for flooring, webbed beams, and shear walls.

High panel shear: Plywood is made with an odd number of layers, making it tough to

bend. The angle at which the veneer grains are laid against each other may be varied from

90 degrees. Each veneer can be laid at a 45 or 30 degree angle to the next one, increasing the plywood╆s strength in every direction┻ This cross lamination increases the panel shear of plywood, important in bracing panels and fabricated beams.

Flexibility: Unlike cut timber, plywood can be manufactured to fit every requirement. The

thickness of each veneer can vary from a few millimeters to several inches. The number of

veneers used also ranges from three to several, increasing the thickness of the sheet. The

extra layers add more strength to the plywood. Thinner veneers are used to increase

flexibility for use in ceilings and paneling.

Moisture resistance: The type of adhesive used to bind the veneers makes the plywood

resistant to moisture and humidity. A layer of paint or varnish can also increase resistance

to water damage. These types of veneers are suitable for exterior use such as cladding,

sheds, and in marine construction. They are also suited for holding concrete while it sets.

Moisture resistance is important in interior applications as well, including on floors. The

cross lamination ensures the veneers do not warp, shrink, or expand when exposed to

Plywood

water and extreme temperature.

Chemical resistance: Plywood treated with preservative does not corrode when exposed

to chemicals. This makes it suitable for chemical works and cooling towers.

Impact resistance: Plywood has high tensile strength, derived from the cross lamination

of panels. This distributes force over a larger area, reducing tensile stress. Plywood is

therefore able to withstand overloading by up to twice its designated load. This is critical

during short-term seismic activity or high winds. It is also useful in flooring and concrete

formwork.

Fire resistance: Plywood can be treated with a fire resistant chemical coating. More

commonly, it is combined with non combustible materials such as plasterboard or fibrous

cement. This makes it ideal for use in fire resistant structures.

Insulation: Plywood has high thermal and sound insulation. This makes it a useful

insulating material for flooring, ceilings, roofing, and wall cladding. Insulation offered by

plywood can greatly reduce heating and cooling costs.

PLYWOOD

╉Types of Plywood╊

There are a variety of ways in which plywood is classified and these classifications are

usually based on the different aspects of plywood such as the wood used, the number of

plies it has, its suitability for indoor and outdoor use, its grading as per quality

specifications, and its intended uses.

Basic types of plywood

MR(Moisture Resistant) Grade Plywood

BWR(Boiling Water Resistant) Grade Plywood

BWP(Boiling Water Proof) Grade Plywood or ╉Marine Plywood╊

Types of Wood Used

Hardwood ‒ Heavier and Stronger

Softwood - Lighter and Weaker

Other Types

Flexible Plywood , that can be bent

Film ‒ Faced Shuttering Plywood For Industrial Use

Structural Plywood for Industrial Use

Fire Retardant Plywood


Plywood

MR (Moisture Resistant) Grade Plywood (low Quality)

MR stands for 'Moisture Resistant' plywood┻ It╆s also known as Commercial plywood and is the most commonly used material for making home and office furniture┻ It╆s an Interior grade and meant for making furniture that will be used indoors.

Water can damage MR grade plywood

Can bend or sag when longer pieces are used.

Difficult to judge the quality of a plywood sheet.

Plywood usually needs additional enhancements.

The edges also need to be covered with suitable pieces of wood.

Costlier compared to block boards, or particle boards.

The adhesives used may be ecologically damaging.

Not considered as strong as solid wood.

People often think Moisture Resistant means waterproof. However this is not the case.

Note that MR (Moisture resistant) is of a lesser quality and cost compared to BWR

grade. While it true that MR plywood can resist a certain degree of moisture and humidity,

it certainly cannot be called waterproof.

MR is interior grade plywood useful for making indoor furniture.


Plywood

BWR (Boiling Water Resistant) Grade Plywood (Standard Quality)

The acronym BWR stands for 'Boiling Water Resistant'┻ It╆s an exterior grade waterproof

plywood, that is better than MR grade plywood. It is the preferred choice of material for

making those pieces of furniture that are likely to get wet. Example, Kitchen cabinets and

other Kitchen furniture. It's also costlier than MR grade ply.

Note: There is also another grade known as BWP, which is more commonly used with block

boards. Similar to BWR grade plywood, BWP block boards are also of an exterior grade

having waterproofing qualities.

The acronym BWP stands for 'Boiling Water Proof', while BWR grade means 'Boiling Water

Resistant' plywood.

The general naming convention used in the industry is that BWR grading is used for

marking plywood, while its counterpart BWP grade is used in the case of Block boards.

Technically speaking there is not much difference between these two terms. The quality

tests on BWR grade plywood sheets, as well as BWP grade block boards are quite similar.

The glue used in the construction of both these types is synthetic plastic resin (phenol

formaldehyde) which is considered better than Urea formaldehyde resins used in

commercial MR grade plywood sheets.

If a board is marked with BWR it means that it is a waterproof exterior grade plywood, and

if it is marked BWP then it should ideally mean that it is an exterior grade waterproof block

board.

Both BWP and BWR grades are widely used in the construction of furniture that is likely to

get some exposure to water. Hence it is a preferred choice of material for making kitchen

cabinets and other kitchen furniture.


Plywood

BWP (Boiling Water Proof) Grade Plywood (Premium Quality)

╉MARINE PLYWOOD╊

As the name indicates, this type of plywood is meant for marine applications i.e. where

flowing water or excessive exposure to water is there. Technically, this is called BWP

(Boiling Water Proof) plywood. In trade circles, this is also called 710 plywood, named so

after the IS standards for this type of plywood (BIS 710). This is the true water-proof

plywood and is made using water-proof phenolic resins. For home and office purposes, this

type of plywood is rarely used, as these to be the most expensive as well.

Commonly used for marine applications such as in the construction of boats and ships. Has

better resistance to water than any other type of plywood. Indian Standard specifications

for marine ply are detailed in the IS document number IS: 710.

2. HIGH QUALITY PLYWOOD

2.1 HUTCH GOLD (BWP)

Plywood comes in a lot of grades and uses. Though we can classify them easily. The best plywood standard marketed by all brands is the Marine Grade Plywood (BWP - Boiling Water Proof). This is generally used for exterior grade furniture or wherever the wood will come in contact with Water. This is also the costliest.

On the other hand, if you want plywood for interior furniture where you know there won't be too much water around, you could go for MR (Moisture resistant) Plywood which will suffices for interior applications.

Hutch Plywood is manufactured from thin veneer sheets. Plywood has been one of the most recognized and trusted wood building products for decades. Plywood panels have good quality structural stability and an excellent strength. They are highly resistant to impacts chemicals changes in environmental temperature and humidity.

For Interior and Exterior applications Hutch Gold plywood is also a best option to go with.



Size: 8x4


Plywood

2.2 HUTCH PLY (BWR)

Benefits of Hutch Ply BWR

1. Good uniform strength

Plywood is a strong material, especially if its made from strong woods (hardwoods) instead

of the weaker woods (softwoods). The image above helps illustrate where this strength

comes from. The darker lines (or the tear lines) that you see on the face of the plywood is

called the wood grain pattern. It is quite easy to tear an individual veneer along the grain,

and equally difficult to tear it across the grain. This is why, whilst making plywood the

layers are arranged such that the grain pattern alternates in each layer, and this is what

makes plywood sheets such a strong material.

2. Can be used for making interior home furniture as well as exterior furniture.

Plywood is available in different grades such as MR grade (moisture resistant) for interior

use, and BWR grade (boiling water resistant) for exterior use. So furniture that is likely to

get wet, such as that in the kitchen or the garden can be made from BWR Water-proof

grade plywood, while elsewhere such as in the living room or bedroom, the cheaper MR

grade plywood can be used. This is a distinct advantage over cheaper materials such as

Particle board which is meant for indoor use only.

3. Available in large sizes compared to solid wood

Its very easy to get a nice looking uniformly thick 18 mm plywood sheet of size 8'x4' (8 feet

x 4 feet) from the market, but quite impractical to get solid flat wood of such a size (which

tree could be cut and how?). According to me, this is the most significant benefit that

plywood offers compared to solid wood, and that's the reason it became so popular since

its discovery. These large sized engineered plywood sheets allow for a variety of

applications that would be difficult to achieve using solid wood.

4. Economical use of wood by mixing various woods together

Some woods are prized for their beauty (teak, oak etc.) but are also costly. The veneers of

such woods can be used to form the surface layer of the plywood, while the inner layers

could be composed of other strong but cheaper woods. Such a mix and match is possible

while constructing plywood and the financial benefits accrued from this, can be passed on

to the end consumer.

5. Available in varieties such as flexible plywood.

Several interesting varieties have now come up in plywood. One of them is flexible plywood

(also known as bendy ply). It can be rolled up or bent to form curved surfaces and allows

for more applications in furniture and home decor.

6. Lesser wastage of wood

In comparison with the process of acquiring solid wood blocks, the plywood making

process has less wastage of material (tree logs), since both the rotary cut and slice cut


Plywood

methods of making veneers do not produce too much waste. So we can utilize more part of

the tree logs in this way.

7. Versatile material that has many applications.

Plywood sheets not only find their way into our homes, by becoming a part of our furniture,

but they also have several industrial and structural applications. e.g. Concrete shuttering

plywood, Marine plywood for boat-making etc.

8. Durable material

Plywood furniture made from good quality hardwood (such as teak or gurjan wood) is

quite durable and lasts many long years. Not as long as solid wood pieces, but much much

better compared to the cheaper Particle board furniture, which eventually needs to be

replaced.

9. Less costly compared to solid wood

Solid wood is better, because its a natural product, but its also very costly. Plywood costs

lesser in comparison. So a reasonable trade-off for most people is to opt for decent quality

plywood to meet their furniture requirements.

3.1 PROMISE PLYWOOD (COMMERCIAL DIPPED PLYWOOD)

In India, when plywood shopkeepers, carpenters and interior designers talk about

Commercial plywood what they usually mean to say is MR grade plywood.

There are different grades of plywood based on quality and characteristics, such as MR

grade, BWR grade, Marine plywood etc. The acronym MR stands for Moisture Resistant,

while BWR means Boiling Water Resistant.

While some people do club BWR grade plywood into the commercial type, for most people

in the Indian plywood industry the term 'Commercial' means MR grade, while 'Waterproof'

means BWR grade.

The important features of MR grade Commercial plywood are listed below.

1. It is an Interior grade plywood, meaning its for indoor use.

2. It is not waterproof. Though the word 'Moisture Resistant' (MR) can confuse many

people into thinking that its waterproof, that is not the case. Being 'moisture resistant' is

not the same as being 'water resistant'. While it is true that moisture resistant plywood can

withstand some amount of moisture and humidity, it cannot be said to be waterproof. On

the other hand, the exterior BWR grade plywood is waterproof.

3. In the case of Commercial plywood, Urea melamine formaldehyde resin is usually used

for glueing the individual plies together. On the other hand, BWR grade is made from

phenol formaldehyde, which is a synthetic plastic resin.

4. MR grade Commercial plywood is the most widely used type of plywood for making

furniture for homes and offices. Drawing room furniture and paneling work, as well as

bedroom furniture is almost always made using Commercial ply. However in those cases

where the furniture is likely to get wet, using BWR grade ply is considered to be better.

5. The Indian Standards specification number for Commercial MR grade plywood is

detailed in document IS:303

Note :The Dipped plywood is comparatively better than Commercial plywood.

3.2 INDUS PLYWOOD (COMMERCIAL PLYWOOD)

Wooden Plywood is redundant since all plywood is already made from wood.

Commercial plywood generally refers to the grade of plywood, most often referring to MR

Grade plywood (IS 303) which is basically the cheapest grade plywood available in the

market. So you could find people asking for commercial Ply or commercial grade ply in the

Indian Market which generally means they want cheap MR(Moisture Resistant / IS 303)

Grade plywood. These plywood are generally made from a combination of softwood &

hardwood timber or just softwood timber species. ╉Commercial Plywood╊ is just a term used in the indian markets for Moisture Resistant Plywood (MR grade Plywood).

The grade of MR plywood is IS303. Most commonly used resin for making MR plywood is

Urea Formaldehyde. Note that this plywood grade is not suitable for furniture that has

exposure to water.

You can use this for wall cabinets and wardrobes. For furniture that has prolonged

exposure to water you can use Boiling Water Resistant (BWR IS303 grade) or MarinePly

(BWP IS710 grade plywood).

Multiwood is a new generation material and its biggest advantage is that it is water

proof. It comes in an attractive white shade and does not decay or absorb humidity.

These benefits make Multi-wood the favourite cabinet material of the new

generation.Since its surface is very smooth, multi-wooddoes not need a layer of

veneer or even polish. It can be moulded to any shape as well.

Multi wood is made from a material that belongs to the category of UPVC polyester

resin.Sheets of the size 8x4 are made by removing the plastic component from the

PVC.

These sheets are available in thickness ranging from 5-25mm. Thin sheets are used

for making cabinet carcases while thicker ones are used for making shutters.

While plywood is available in the form of multiple layers , the multi-wood comes in a

single layer and helps in shutter operation without any rattle. Another advantage of

muyltiwood is that it can be drilled and engraved upon. The material is generally

lightweight in nature and can be bent with the help of a heat blower.

A multiwood is resistant to termites and does not easily catch fire. It is an Eco ‒

Friendly material and can be recycled and used.


Plywood

A disadvantage of multi wood is that if it kept for drying under the hot sun after

painting, the material has a tendency to get warped. Therefore, it is advisable that

after painting the furniture is kept for drying at a place where there is no direct

sunlight. MULTIWOOD is made up of ╅U╆ Pvc polyester resin ┃ is made in an extruded polymer profile form. It is 100% waterproof, Termite & Borer proof, corrosion free

2. THOMSON ECO BOARD

ECOBoard panels are high quality industrial grade panels, manufactured from agrifibre

(agricultural residue) that is milled to form flakes. The flakes are then mixed with a

specially designed formaldehyde-free resin and compressed under high temperature to

form a stable homogeneous panel. Panels can be custom made to specifications.

ECOBoard panels can replace plywood, chipboard, OSB type-3 boards, multiplex and

conventional fibreboards (including MDF, hard-board and soft-board) for a wide range of

applications. ECOBoard panels were benchmarked against wood based panels in terms of

strength and specification and can be cross referenced to any international particleboard

standard such as BSEN 312 P4 to P1 or ANSI A208.1.

ECOBoard panels can be used in virtually all applications where conventional boards are

used like in following applications;

* Furniture Industry

* Interior Decoration Industry

* Building Industry

* Construction Industry

* Industrial Packaging

Due to the fact that there is formaldehyde-free added resin (NAF) being used, ECOBoard

panels have emissions far below the strict E0 European low formaldehyde (LF) and the

USA (HUD 24) standards. ECOBoards therefore are suitable for use in environmentally

sensitive areas such as;

1. Schools

2. Nurseries

3. Children╆s Furniture

4. Hospitals

5. Public Buildings

6. Laboratories

7. Nursing Homes

Or any domestic application with concern for the living environment and sustainable

lifestyles.

HDF- HIGH DENSITY FIBRE BOARDS (One Garde available)

EXTERIOR

Medium-density fibreboard (MDF) is an engineered wood product made by breaking

down hardwood or softwood residuals into woodfibres, often in a defibrator, combining it

with wax and a resin binder, and forming panels by applying

high temperature and pressure.MDF is generally denser than plywood. It is made up of

separated fibres, but can be used as a building material similar in application to plywood. It

is stronger and much denser than particle board.

MDF is an engineered wood composite that is similar to particle board, but is much denser

and stronger than particle board.

Imagine if all of the sawdust was swept up from other wood product manufacturing

processes, and then that sawdust was mixed with binders and pressed into large sheets the

size of plywood. Okay┸ that╆s way oversimplified┸ and it╆s not exactly the process they use

to make MDF, but that gives you an idea of the makeup of the product. Because it╆s composed of such small wood fibers┸ there╆s no wood grain in MDF┻ And because it╆s pressed so hard at such high temperatures┸ there are no voids in MDF like you find in particle board. Here you can see the visible difference between particle board and

MDF, with MDF on the top and particle board on the bottom.

Advantages of MDF

MDF is generally cheaper than plywood.

The surface of MDF is very smooth┸ and you don╆t have to worry about knots on the surface.

Because it╆s so smooth┸ it╆s a great surface for painting. I recommend first priming

with a quality oil-based primer. ゅDon╆t use aerosol spray primers on MDF┿┿ It just

soaks right in, and is a huge waste of time and money. It will also cause the surface to

become rough.)

Also because of its smoothness, MDF is a great substrate for veneer.

MDF is very consistent throughout┸ so cut edges appear smooth and won╆t have voids or splinters.

Because of the smooth edges, you can use a router to create decorative edges.

The consistency and smoothness of MDF allows for easy cutting of detailed designs

(such as scrolled or scalloped designs) using a scroll saw, band saw, or jigsaw.

Disadvantages of MDF

MDF is basically glorified particle board.

Just like particle board, MDF will soak up water and other liquids like a sponge and swell unless it╆s very well sealed on all sides and edges with primer┸ paint┸ or another sealing product. Again, I recommend a quality oil-based primer. No aerosol spray

primers!!

Because it consists of such fine particles, MDF doesn╆t hold screws very well┸ and it╆s very easy to strip the screw holes.

Because it╆s so dense┸ MDF is very heavy┻ This can make it more difficult to work with┸ especially if you don╆t have a helper who can help you lift and cut the large sheets.

MDF can╆t be stained┻ Not only does it soak up stain like a sponge, but also because there╆s no wood grain on MDF┸ it looks awful when it╆s stained┻ (Kind of like staining

particle board. Why would you bother?)

MDF contains VOCs (urea-formaldehyde). Off gassing can be greatly minimized (but

probably not eliminated) if the MDF is encapsulated with primer, paint, etc.

MDF does not contain knots or rings, making it more uniform than natural woods during

cutting and in service. However, MDF is not entirely isotropic, since the fibres are pressed

tightly together through the sheet. Typical MDF has a hard, flat, smooth surface that makes

it ideal for veneering, as there is no underlying grain to telegraph through the thin veneer

as with plywood. A so-called "Premium" MDF is available that features more uniform

density throughout the thickness of the panel.

MDF may be glued, doweled or laminated. Typical fasteners are T-nuts and pan-head

machine screws. Smooth-shank nails do not hold well, and neither do fine-pitch screws,

especially in the edge. Special screws are available with a coarse thread pitch, but sheet-

metal screws also work well. Like natural wood, MDF may split when woodscrews are

installed without pilot holes.

2. HIGH DENSITY FIBRE BOARDS (HDF)

EXTERIOR GRADE

HDF board is a wood fibre board made from fine wood fibres. The board is homogeneous

through and through, has a particular dense, smooth, surface which is harder than MDF

board. Due to its flatness and excellent treatment possibilities HDF board can be cut,

drilled, painted or processed in other ways.

HDF board is mainly used to build furniture such as kitchen cupboard doors, tables etc.

This material is also used in

Raw Material

HDF is High Density Fiberboard and is similar to particle board and medium-density board

but it is much denser and stronger. It is made by compressing wood fibers mechanically.

Style/Finishing

HDF is a much stronger board compared to MDF and it gives a smooth and uniform surface

wherever it is applied. HDF does not have any grain and it can be finished by applying paint

on it. If you want wood grain finishing then you would need to put a veneer or teak ply on

the HDF board

Maintenance

To protect HDF the steps below should be taken.

Make sure that the board does not get in touch with water as it can damage it.

Clean the board with a clean soft cloth to remove the dust.

Do not mop with damp cloth.

Once you finish the HDF with paint or veneer wood then the maintenance steps for

those finishes should be followed accordingly.

Advantages

HDF comes with a smooth surface.

HDF is High density board has more strength compared to MDF and Particle board

Great solution for indoor and outdoor furniture, wall paneling, furniture, room

partitions, and doors.

Disadvantages

HDF is the best board when compared with particle board and MDF. Still a lot of carpenters

prefer wood block board compared to HDF as they are more confident about the nail

holding capabilities of natural wood whose blocks are used to build the block board.

SHUTTERING PLYWOOD

Shuttering Plywood is a highly densified plywood with a smooth film coating on both sides

of the faces and is used primarily for cement formworks during construction.

What I mean by densified is that atleast 9 layers of core veneers (10 in the case of ours) are

pressed in a high pressure pressing machine at high temperatures. 9 core layers plus the

faces on both sides plus the film layers (Dynae Film) on top of them. So its a 1+1+9+1+1

construction pattern. We at Avron use a 1+1+10+1+1 construction pattern which lends the

plywood extra strength and load bearing capacity.

The plywood is generally pressed to a thickness of 12mm with a density of 750Kg/cubic

metre to ensure it supports the weight of poured concrete. SHuttering Ply is generally used

to make the cast of ceiling, walls, drains, highways, pillars, etc, to p0ur concrete in it in

order to give the concrete any shape needed.

Common Uses: Construction, Repair and Maintenance of Buildings, Bridges, Beams, Fly-

overs, heavy commercial Vehicle and truck Bodies, Roofing, water tanks, cooling towers,

building, metro rail track projects, lofts, flyovers and mezzanine floors.

This plywood is available in different weights and densities.

BAMBOO PLYWOOD

Bamboo Plywood or bamboo sheets have become one of the most talked about building

products in the last year, among green building professionals and architects. It is versatile

and renewable. It is not a tree but a grass--bamboo can grow to maturity in as little as one

growing season, yielding many harvests over a typical 25-50 year tree life cycle. Bamboo is

typically harvested after only three years of growth but four to five year-old bamboo is a

more stable raw material for the production of bamboo panels.

Bamboo panels and bamboo sheets provide for many current and future needs for

sustainable raw material streams and is a valuable NTFP (non-timber forest product).

Bamboo is used extensively around the world for construction materials including: roofs,

walls, floors and concrete forms--because of its remarkable strength. Bamboo panels or

bamboo sheets are also attractive materials for construction of cabinets, furniture and a

myriad of household furnishings and products

After processing split bamboo with machines and glue, bamboo board can be produced for

almost all purposes where timber is now used. Bamboo mats and slivers are hot-pressed to

produce bamboo ply board. Bamboo ply board is very strong and it can be made water

resistant for natural and carbonized bamboo plywood and panels. Vertical grain bamboo

plywood and horizontal grain bamboo plywood are the most prolific forms of this new

construction material and it is produced as natural or carbonized in color.

2.3 CHEQUERED PLYWOOD

This is an anti-skid plywood which is useful in flooring specially in heavy vehicles and large

containers. It is useful in automobile sector for ceiling, paneling, seat back rest etc.

It is widely used for flooring in industrial as well as public areas. The product provides a

friction-resistant, anti-skidchequered surface, which is bonded with superior grade

phenolic resin,thus finds application in the flooring of in heavy vehicles and large

containers.It is a medium-density plywood, which processes excellent strength, durability

and all weather resistance. Chequered plywood is treated on both sides with thermo

setting phenolic resins and micro-organism resistant chemicals.This treatment protects the

boards from chips, wraps, twists, termite,fungus,rot and abrasive action of water, sand and

extreme weather conditions.

Using large chequered plywood can reduce the time and labour in laying bus and truck

floors.It requires no pre/post treatment at the work site thereby cutting down costs

considerably.The chequered plywood is an ideal blend of low weight, high strength, and

high resistance to abrasion and extreme weather.

Uses of Chequered plywood

BLOCK BOARDS

By definition, blockboard is an engineered wooden board that consists of a core of

softwood blocks (strips) lined edge to edge and sandwiched between layers of hardwood

veneer on either side. In this article we will take a look at the important properties of

blockboards.

Properties

These boards have good dimensional stability (even when exposed to humidity), and

exhibit high resistance to warping or twisting.

Also have a better ability to hold nails and screws, compared to other engineered

boards such as particle boards or MDF (medium density fibre boards).

Another important characteristic of blockboard is that it is light in weight, because the

core blocks that form the bulk of the board are of softwood that has much lesser density

and weight compared to hardwood. Because of having low weight it is easier to

transport.

Can be finished using paints, varnishes or can be laminated. With proper finishing such

as by glueing laminates on its surfaces, blockboards can be made to appear exactly like

their costlier counterparts viz. plywood

Another feature of blockboards is that they can are also easy to work with for

carpenters using their regular wood working tools. In contrast, carpenters find it very

difficult to work with other engineered boards such as MDF or Particle boards as these

types do not hold nails and only screws have to be used.

These boards are made in MR-Moisture resistant grade, as well as BWP-Boiling water

proof grade, for interior and exterior use respectively. The BWP variety uses superior

glue (phenol formaldehyde), and is stronger with better resistance to water or

humidity.


Plywood

Advantages of Blockboard

Lighter in weight:

The blockboard core is made from solid blocks of wood that is usually obtained from

softwood trees such as pine, mango or cedar. In comparison good quality plywood is often

made from veneers obtained from hardwood trees (e.g. Gurjan wood which is very popular

in India), and the high quality solid wood that is used in furniture is generally obtained

from hardwood trees such as teak wood.

Because hardwood is denser than softwood, its weight is also more. So if you take a piece of

plywood or solid wood and compare its weight with a blockboard piece of the same size,

you will find that blockboard is lighter in weight.

The advantage of being light-weight is that it can be more easily transported to the end-

location. The most common application of this is in the case of doors that we use inside our

homes. Doors are very often made from blockboard.

Lesser tendency to sag or bend

In cases where very long pieces of wood are required in furniture making, such as in long

book shelves, panels, benches and tables, blockboard is often preferred over plywood. This

is because long plywood pieces tend to bend in the middle, whereas blockboard is stiffer

and less prone to bending. When the board length exceeds 6 or 7 feet, blockboard is

generally used instead of plywood.

Costs Less

Another important advantage of blockboard is that it is cheaper than good quality solid

wood as well as hardwood plywood. This is because softwood costs lesser than hardwood.

Better than Particle Board and even MDF

Compared to other engineered wood products that are popular these days, such as Particle

boards(which is made from small particles of wood flakes/chips) and even MDF (which is

made from wood fibers), blockboard is considered to be better. It is comparatively stronger

and lasts longer. Also from the carpenters' point of view, the added advantage of

blockboards is that it is easier to work with, since it can take nails as well as screws. In

comparison, particle board and MDF do not have much nail holding strength and hence

only screws are used on them. In fact most of the carpenters in India who make custom-

built furniture work only with plywood and blockboards, and not MDF or Particle boards.


Plywood

Disadvantages of Blockboard

Not as strong as plywood or good quality solid wood

The major disadvantage of blockboards is that since softwood is used in its making, it is not

as strong as quality solid wood (such as teak wood) or hardwood plywood. So when it

comes to furniture making, plywood is the preferred choice of material (except for cases

where lengthy wood pieces have to be used). However, if instead of softwood blocks,

hardwood is used to form the blockboard core (some manufacturers do this), then the

strength of the blockboard increases.

Minor disadvantage for carpenters

In some cases, the blocks (also called strips or battens) that form the core, may have small

gaps between them. These gaps cannot be seen from outside since there is layer of veneer

on top. Because of this, sometimes the nails that are driven through the board surface may

not go into the wood but rather in the gaps between the blocks, which can adversely affect

the holding strength of that nail. But this is only a minor drawback, that occurs only

sometimes.

RUBWOOD

What is Rubwood?

Rubber plantations have existed for hundreds of years in Tropical countries. These

Plantations have been used mainly for the production of latex. After the economic life of

the rubber tree, which is generally 30 years, the latex yields become extremely low and the

planters then fell the rubber trees and plant new ones. This eco-friendly Rubber wood

(Hevea Brasiliensis) when Processed becomes an excellent substitute for hard wood. We

can make the eco-friendly rubber wood, making furniture and finger jointed edge glued

panel boards. These products are marketed under the brand name of ╅RubWood╅┻

HARD WOOD

Hardwood Plywood generally refers to the make of the plywood, which is the timber used in construction the layers of plywood. Hardwood generally is ascribed to hardwood timber species such as Eucalyptus, Gurjan, Birch which is higher in density and are much more long lasting than other timber species such as rubberwood or poplar. Plywood made from hardwood timber are generally heavier in weight, higher in density and have much longer life than softwood plywood. I would suggest opting for hardwood plywood with a Eucalyptus timber make to make sure the plywood is strong, lasting and most importantly sourced from ecologically sustainable cultivations.

Hardwood plywood refers to what material each ply is made of. In regular 3-ply plywood,

each ply is usually constructed of pine or some other softwood╆s wood-chips and glue then heated and pressed into a ね旺 by ぱ旺 sheet┻ Each ply is then glued to another until you have built up the appropriate amount of plies. So in hardwood plywood┸ they won╆t use wood chips┸ but multiple thick strips of hardwood to make up the layers of each ply. Hardwoods are more expensive than softwoods, so

hardwood plywood would be more expensive.

WOOD VENEER

Wood veneer is the finest expression of wood. Veneer is a thin layer of wood which is cut

from a log. The main difference with solid wood is that solid wood is sawn from a log. This

produces more waste than when cutting wood veneer. In other words, processing a log into veneer let╆s maximize the added value that we can obtain from a log. No other natural

product is able to offer this unique added value. Decospan has developed its activities

entirely around this sustainable and exquisite raw material.

WOOD VENEER APPLICATIONS

Wood veneer is mainly used for interior decoration applications in many different

segments. It's ideal for residential projects, hotel projects, offices and many more. In

addition, veneer is also processed to create a variety of products such as veneer parquet,

flexible veneer sheets, wood veneer boards, wood veneer wallpaper, etc. In other words,

veneer can give any interior a unique look and feel.

Decospan wood veneer is available in more than 165 different standard wood species.

Specific wood species can be sourced in the market upon request. The thickness of the

veneer is between 0.5 and 2 mm depending on the wood species used and/or the

application.

EACH VENEER IS UNIQUE

Every tree is different so every veneer product has a unique appearance. The same tree can

never be found twice in nature. This also means that the colour and pattern can vary within

the same wood species. After all, veneer is real wood and not an imitation like laminate or

melamine. The latter are both imitations of wood on paper.

The color of wood veneer is also influenced by light in the room and this can give the wood

an even warmer feel. The numerous imitations of different wood types have made it

difficult for the consumer to distinguish the real natural product from the imitations.

The wood structure which is unique for every piece of wood veneer, the color which

continues to enhance the appearance, the ability to repair and renovate are just some of the

advantages that distinguish the real thing from the would-be products.

Veneer refers to thin slices of wood that are practically peeled of the wood. The slices are

usually less than 3 mm (1/8 inch) thick. The thin slices can then be glued together to create

either laminated wood or plywood. Plywood typically consists of three or more layers of

veneer.


Plywood

The veneer can also be glued onto core panels, such as wood, particle board or medium-

density fiberboard. This gives the said wood, particle board or medium-density fiberboard,

the look of the wood that the veneer was cut from. The veer covered wood, particle board

or medium-density fiberboard can then be used to produce flat panels such as doors, tops

and panels for cabinets, parquet floors and parts of furniture. Veneer beading is a thin layer

of decorative edging placed around objects, such as jewelry boxes.

Veneer is usually obtained either by peeling the trunk of a tree or by slicing large

rectangular blocks of wood known as flitches.

Advantages

Beautiful:

The best, most interesting logs are cut into veneer. This is largely an economic decision--

sellers and veneer makers can make more money from a high quality log sliced into veneer

than they can from sawing it into boards. And certain cuts, such as burls, are structurally

unsound in 'the solid'. These beautiful woods can rarely be utilized unless they're sliced

into veneer

Environmentally Kind:

Saw timber is typically sawn into 1" thick boards. The saw cuts a kerf between boards 1/4"

thick that winds up as sawdust. Veneer is not cut from the log but sliced with a knife (like

lunch meat) into 1/32" leaves or sheets. That produces 32 veneer surfaces for every 1 that

is gotten from a board and with no wood wasted as sawdust another 8 sheets where the

saw blade would have gone. That's 40 surfaces of wood veneer for every 1 of solid wood.

Creates New Design Possibilities:

Since veneer is so thin and is glued to a stable substrate it allows designs and arrangements

of the wood that would fail in solid wood. Solid wood, even kiln-dried, moves or works

from summer through winter through summer again. A radiant table top would be

impossible in solid lumber because the seams would open in winter and swell tightly shut

in summer. Cross grain designs such as aprons and edge bandings are also impossible in

solids. Solid burls are also largely unusable but frequently used in veneer.

Stable:

Since veneer is glued with a waterproof adhesive to a stable substrate it produces surfaces

not prone to warp or splitting or seasonal movement.

Substrates:

Plywood and medium density fiberboard are substrates used for furniture, are made from

low quality trees. This means a market is provided the landowner for these trees. This

leads to better forests over time since the trees remaining grow better and faster with less

competition for resources. It╆s like weeding your garden only a lot bigger.

MICA LAMINATING SHEETS

Mica traditionally refers to a group of sheet silicate minerals that have numerous different

applications today, including in the creation of window panes and glass, as an insulator in

various electric, and even in toothpaste. This is mainly due to the fact that mica is generally

stable when exposed to electricity, light, moisture, and extreme temperatures. In

toothpaste, mica acts as a mild abrasive that aids in polishing of the tooth surface. Ground

mica is often also used in cosmetics industry to add the glittering finish in the products.

However, when referring to mica in the same context as wood, mica is generally another

name for laminates.

Laminates, specifically, are a multi-layer synthetic wood product. It is created of high-

density fiber, melamine resin or wood particles. On top, the laminate has a photographic

applique layer, which is in turn covered with a clear protective layer. The photographic

applique layer is usually imprinted with various images that aim to imitate the appearance

of real wood. Laminates are usually applied over plywood or fiberboard, so that they can

duplicate the look of wood for a cheaper cost. In case of laminated wood, the wood veneers

are pasted parallel to each other, as opposed to the right angles in plywood.

In addition to being cheaper, laminates are scratch-resistant, durable and easier to clean

than traditional wood. It is easier to maintain, as the clear protective layer is resistant to

pretty much everything except long exposure to water. This makes is longer lasting and

well suited to be used in homes with kids and pets. Another advantage to laminates is that

they are environmentally friendly as they use less wood to be manufactured, if any at all.

However, long time exposure to water or moisture may result in the laminate warping or

ballooning. Moreover, the look of the laminate is set by the manufacturer, as opposed to

wood that can be sanded and re-stained in any color of the stain available. Nonetheless, as

the laminate is basically an image printed on it, the choice is pretty much limitless, and

some manufacture may be willing to take custom orders. Still, laminates lack the visual

warmth of wood.

While they are more durable than wood, laminates have a relatively shorter life-span as

compared to traditional wood. The average life-span of laminate is between 10 to 20 years.

It is also very hard to repair laminates, if it is damaged in any way or has run its course, the

entire furniture may have to be replaced.


Plywood

Similarities between mica Laminate sheets and Veneers

The main similarity between Laminates such as mica and veneer is in the way these two

materials are used. Both are used as an overlay over wood. In the way that mica sheets are

glued to plywood, in the same way a teak veneer can also be glued over plywood or any

other wood. When wood veneers such as teak veneer is attached to the base wood, the final

appearance of the furniture is like teak wood furniture, though inside wood of lower cost

can be used.

The other similarity between the two substances is that decorative laminates being

artificially created materials can have a variety of designs and patterns on them. Often the

most popular mica designs are those that look like wood. So you can have a mica that has a

teak wood design, though it will still feel different to the touch. You can also get a similar

look by attaching a teak wood veneer over the base wood.

Differences between Laminate sheets such as mica and wood veneers

The main difference between mica/laminates and veneer is the material. wood veneers are

thin sheets or slices of wood, while mica or other laminates are a blend of paper and plastic.

Another important difference is in the availability of designs. Since veneers are made from

wood they will always have wood grain designs and a wood appearance, on the other hand

since mica is created using artificial means (and uses decorative printed paper) it can have

a wide variety of colors, patterns and also textures.

Table tops or other furniture that have mica or other laminates on top, are not easily

affected by water, as also the surface is quite resistant to scratches and other wear and

tear. Furniture decorated with wood veneer on the other hand, has to be cared for as you

would take care of any other wooden furniture item┻ It╆s a wooden surface┻ A drawback of laminates is that it is a brittle material and is prone to chipping (especially if

it is not adhered to the wood firmly). Another point is that many people prefer the more

natural look and feel of veneers compared to the artificial looking laminates.

SKIN DOORS

A molded door has the same structure as that of flush door. The only difference is that the

surface material is a molded skin made of HDF / MDF. It is commonly used as interior

doors.

Construction of Skin doors

Stiles - Vertical Frames that run the full height of a door and compose its right and left

edges. The hinges are mounted to the fixed side (known as the "hanging stile"), and the

handle, lock, bolt, and/or latch are mounted on the swinging side (known as the "latch

stile").

Rails - Horizontal Frames at the top, bottom, and optionally in the middle of a door that

joins the two stiles and split the door into two or more rows of panels. The "top rail" and

"bottom rail" are named for their positions. The bottom rail is also known as "kick rail". A

middle rail at the height of the bolt is known as the "lock rail", other middle rails are

commonly known as "cross rails".

The Stiles and Rails form the outside edges of the door

Skin - front and back faces of the door are covered with HDF / MDF skins

We can make molded interior doors with strong, environmentally conscious materials. The

skins are available with a smooth surface or various wood grain textures. Molded doors are

primed and can be painted whatever color you wish.

Skin (Panel) Doors versus Flush Doors

The main difference between a panel door and a flush door can be found in their

construction. The design of a panel door features stiles and rails. A stile is a length of wood

positioned vertically on a door. Rails are lengths of wood that run horizontally across a

door. The flat panels of the door fit between its stiles and rails. Alternatively, a flush door

has a flat, smooth surface without the elaborate design work of a panel door. A flush door is

made up of a single solid piece of wood. Both types of doors can be made with different

kinds of wood and can be found in a variety of colors.


Plywood

Popular Reasons for Choosing a Panel Door

One of the reasons for the popularity of panel doors is that they are more decorative than

flush doors. The texture of panel doors can add interest to the décor of a room. Plus, there

are different styles of panel doors. One homeowner may choose to get a panel door with

one stile and one rail while another person wants to get a six panel door that includes three

stiles and three rails, according to finish carpentry help. In short, there are more options for

someone who chooses to install panel doors in his or her home. In addition, the actual

panels in a panel door expand and contract with changing humidity levels. This can help to

prolong the life and appearance of this type of door. Many people choose a panel door for

the exterior of their home. They want to make a stylish first impression with visitors.

Popular Reasons for Choosing a Flush Door

Of course, there are many individuals who prefer flush doors over panel doors. A person

getting a flush door has the choice between one with a hollow construction and one that is

solid inside. A closed flush door of solid construction keeps more noise out of a room than

one with a hollow construction. Plus, a solid flush door helps to keep the warm air inside a

room during the wintertime and keeps the air conditioning inside during the summer.

Since flush doors are easier to create than panel doors, they tend to be less expensive.

Finally, individuals who are trying to decide between a panel door and flush door should

think about whether they want a decorative door or a more practical one. The price

difference between a panel door and a flush door can also play a large part in a person╆s final decision, especially if he or she is buying a complete set of doors for a home.

VENEER DOOS

In woodworking, veneer refers to thin slices of wood, usually thinner than 3 mm (1/8 inch),

that typically are glued onto core panels (typically, wood, particle board or medium-density

fiberboard) to produce flat panels such as doors, tops and panels for cabinets, parquet

floors and parts of furniture.

Laminate or veneered doors ‒ which is better

Most frequently veneer in repair-building sphere can be found in door production. What

door is better to choose: of veneer or laminate? Such a problem of choosing is always faced

by everyone who decides to renew the apartment with his own hands.

It should be said immediately that solid wood is used for the frame of both types of doors,

this solid wood is usually attached to MDF boards, so, the difference between them is only

in the top finishing layer.

Veneer is a natural material; therefore, the color and texture of door panels made of it are

traditional, natural and noble, in contrast to laminate. These doors look gorgeous in a

classic interior.

Laminated panels, for its part, covered by an artificial material ‒ laminating membrane

applied to MDF, which is less environmentally friendly. Nevertheless, laminated products absolutely do not limit the wild flights of designer╆s imagination┸ because they can be of any desired color and texture. Therefore, the choice of laminated or veneered surface depends

only on the preferences of the consumer.

WHAT IS UPVC

OVERVIEW:

UPVC is based on polyvinyl chloride (PVC), one of the most versatile polymers found in the

century. PVC today finds application in almost all facet of our life, from daily use to highly

sophisticated life saving applications. This flexibility of PVC is leveraged through a unique

formulation to prepare a special UPVC blend for windows and doors.

UPVC (where 'U' stands for unplasticized) is one of the most preferred window framing

material across the world. The material comes in a range of colour, is low maintenance and

offers benefits which no material so far has matched. This has helped UPVC garner more

than 50% market share in countries like UK, USA where it is also known as vinyl or vinyl

siding.

BENEFITS OF UPVC WINDOWS:

UPVC windows and doors offer many of the performance characteristics which no other

material so far has achieved

FORMULATION:

UPVC is prepared with a special formulation in which modifiers and stabilizers are added

to polyvinyl chloride (PVC) making it rigid and suitable for use as window frames.

PVC: PVC forms the major (approx 80 - 85 %) constituent of blend composition. PVC unlike

other polymer is heat sensitive and hence needs additives for processing. The property of

material is such that it can be made as soft as rubber or can have strength close to any

other engineered plastic. This versatility is developed through additives (like light & UV

stabilizer, processing aids, impact modifier, lubricants, fillers, pigments, plasticizer etc.)

which are added in PVC during the blending process.

Stabilizer - Heat & Light: As PVC cannot be processed due to its heat sensitive nature,

Heat stabilizers are must to improve the stability of PVC and render it process-able.

Sufficient stabilizer is required to prevent degradation of base material during processing.

Lack of sufficient stabilizer may lead to early discoloration of profile when exposed to

sunlight. Since windows are subject to harsh condition of Indian climate - High

temperature, the formulation should also take care of endurance of profile to continuous

exposure of heat & UV. This typically applies for PVC window profile in the tropical zone

wherein the profile is exposed to high temperature with UV radiations. For this light

stabilizers are used in recommended dosage.

Processing Aids: These are generally acrylic based material which enhances the melt

strength during fusion and contributes in smooth extrusion of profile with uniform cross

section.

Impact Modifier: Typically polymers tend to become brittle once subjected to low

temperature or exposed to UV radiation. Acrylic based impact modifiers are used to retain

impact strength even after UV exposure and at low temperature. Insufficient dosage or low

cost impact modifier (like CPE) may not be able to withstand the impact resistance over

long period of usage and may become brittle / crack during fabrication, installation,

operation or usage.

Lubricants: These additives are used to manoeuvre the process-ability of PVC in the

extrusion process. Excessive or insufficient usage of the lubricants may cause product

defect.

Pigments - Titanium Di-Oxide: Titanium Di-oxide is an expensive pigment which is used

as white pigment, imparting natural white color to the PVC profile and provides the

necessary UV stability for the product to have durability over years of usage. The dosage of

TiO2 depends upon the UV radiation of the region. Typically the dosage ranges from 4 parts

for climate similar to Europe and 10 parts for harsh tropical climate like Arizona, India, etc.

The pigment also gives opacity to the product.

Other pigments (organic / inorganic) & brightener are used to color the pigment but may

not have similar UV stability. These should be used cautiously ensuring the weather

resistance and color fastness.


Plywood

Fillers: These are inorganic minerals (like calcium carbonate) as fine particles

homogenized in the PVC blend. Usage of filler has effect on mechanical property (tensile

strength, elongation and impact strength), shrinkage and cost. When used in designed

proportionate improve the mechanical strength of the polymer and if used in excessive

though reduces the cost but impairs the durability of product.

A decision that many homeowners face when looking to renovate their home or while

designing a new home is whether to opt for wood, aluminium doors or uPVC doors and

windows. Unplasticized Polyvinyl Chloride or UPVC doors and windows have shot up in

popularity in recent years and are being widely used in homes. They make a great value

addition to any home and installing them would be one of the best decisions any homeowner can make to enhance their house╆s functionality and overall usability┻ Weighing up the pros and cons is never easy either but with our guide, we have tried to list

out all possible uPVC doors windows advantages and disadvantages.

Advantages:

Installing uPVC doors and windows have a string of advantages. Some of them are listed

below:

1. Durable and Sturdy

o One the major advantages of uPVC windows and doors are that they are much stronger and

made out of far more durable material than traditional wooden doors partly due to the manner

in which they are constructed. This not only makes them long lasting and resilient but also

makes it highly unlikely that you will ever need to change your door again. UPVC is an

exceedingly durable material and ensures your door will stand the tests of time and never lose

their shape.

2. Easy to Maintain

o UPVC doors and windows require very little maintenance and unlike wooden doors, are not

prone to rotting, flaking, rusting, fading, or corroding. Besides, they are weatherproof and rigid

and can be cleaned easily with just an occasional wipe-down. Frequent oiling might be

required for the locking mechanism from time to time.

3. Insulation and environmentally friendly

o Renowned for the high level of insulation they provide, UPVC windows and doors not only

keep you warm during winters but are also sound-proof and help cut noise levels considerably

which goes a long way in reducing stress levels.

o Additionally, because they keep out the cold and dampness and prevent warm air from

escaping, you end up using less electricity which has a positive impact on your energy bills.

Plywood

Saving energy makes UPVC doors and windows more environmentally friendly than its

wooden and aluminium counterparts.

4. Enhanced Security and Hazard Resistant

o UPVC doors and windows provide a much better level of security than traditional wooden

doors. They are reinforced with galvanised steel which makes them extremely hard to be

broken down or forced open. Moreover, uPVC is a stable material which makes it sea-water

resistant, pollution resistant and also chemical proof while naturally being flame retardant as

well.

5. Pricing

o uPVC doors and windows are significantly cheaper than both wooden and Aluminium options.

SUNPACK SHEETS

Sunpack is also known as plastic corrugated sheets. It comes in different colors like red,

green, blue, white etc. As per Hindustan Times report published in 2015, sunpack

nowadays is widely used outdoor medium for advertisement for small Enterprises

and household. Being inexpensive give them an added advantage over wooden frame flex

boards. Another advantage of the sunpack sheet is that due to availability in number of

colors there is no need to print background color as required in flex.

Color sun pack sheets ensure that there is no fading off background and print quality

issue. Overall print quality is superior to that in normal flex.
