Content

The Presidential Decree 1096 otherwise known as The National Building Code of the Philippines is the mandatory rules and regulations in building construction.

It is the policy of the State to safeguard life, health, property, and public welfare - consistent with the principles of sound environmental management. The National Building Code provides the framework and the minimum standards or regulations for all buildings and structures in order to control the building’s:

• Location • Construction • Site • Use • Design • Occupancy • Quality of material • Maintenance

The Code covers the following disciplines: architectural, civil/structural, electrical, mechanical, sanitary, plumbing, and electronics. This shall also apply to design, location, siting, construction, alteration, repair, conversion, use, occupancy, maintenance, moving, demolition of, and addition to public and private buildings and structures, except for traditional indigenous family dwellings, and those covered by Batas Pambansa Bilang 220 otherwise known as the “Economic and Socialized Housing Projects”.

Building systems incorporating plasterboard can help meet the requirements of the Fire Code of Philippines 2008 by:

• Providing surfaces that minimise fire spread • Creating compartments that limit the progress of smokes and flames • Maintaining the structural integrity of the structure as a whole

Republic Act No. 9514 or the Fire Code of the Philippines of 2008 is interpreted as the policy of the State to ensure public safety, promote economic development through the prevention and suppression of all kinds of destructive fires and promote the professionalization of the fire service as a profession. The State shall enforce all laws, rules, and regulations to ensure adherence to standards fire prevention and safety measures, and promote accountability in the fire protection and prevention service.

Both the National Building Code and Fire Code cover the Implementing Rules and Regulations in building constructions in the Philippines. The administration and implementation of the Code are vested in the Secretary of Department of Public Works and Highways (DPWH) and Bureau of Fire Protection (BFP) through the Local Government Units who reviews the plans and issues the permits for construction. Refer to the minimum requirements for fire rating limits of buildings as stipulated in the Philippines National Building Code on page 19.

Fire Compartmentation

Introduction

The concept of fire resistance is the ability of a structure to maintain its structural capability and prevent the spread of flames or heat when exposed to fire conditions.

The gypsum that makes the core of USG Boral’s Type X Plasterboard portfolio is specially formulated to resist the dehydration by heat in the event of a fire.

USG BORAL TYPE X PLASTERBOARD

Fire compartmentation is a concept where the spread of fire within a building is restricted by partitioning walls or floors with fire resisting walls or ceilings. These partitions can also deter the spread of smoke which allows for a safe mode of escape during an emergency.

UL Introduction

Underwriters Laboratories, UL is a global safety consulting and certification company (104 countries). It is one of several companies approved to perform safety testing by the U.S. Federal Agency Occupational Safety and Health Administration (OSHA). OSHA maintains a list of approved testing laboratories, which are known as Nationally Recognized Testing Laboratories.

How does UL Certified Fire-Rated System work?

1) All UL certified fire-rated products are tested under UL witnessed program2) Upon successfully passing the fire tests, the following taking place: • Minimum board weight is established • Formulation is also set for future production • The product is assigned a designation code • The product with specific designation code (as well as corresponding commercial name) will be listed in the approved fire-rated assemblies with key installation details (i.e. UL Designs) • The UL Designs will be added to the UL fire-rated system directory and can be accessed online publicly • The manufacturer will be issued an approved message that is to be printed on every single UL certified board to ensure only qualified products are installed in the job site • UL will also conduct regular plant inspection and review production record to ensure the compliance to its program

3) The following are the UL designation of USG Boral UL Certified products : • DCB- USG Durock® Cement Board • Type EX-1- 15.9mm (5/8”) Fire-Rated Plasterboard from Saraburi Plant • Type C- 15.9mm (5/8”) USG Boral Sheetrock® Firecode® Type C from Oman Plant • SCX- 15.9mm (5/8”) USG Boral Sheetrock® Firecode® X from Oman Plant • SGX- 15.9mm (5/8”) USG Boral Sheetrock® Glass-Mat Mold Tough® Firecode® X from Oman Plant • USGX- 15.9mm (5/8”) USG Boral Securock® Glass-Mat Sheathing Firecode® X from Oman Plant

USG BORAL’S UL CLASSIFIED FIRE-RATED PLASTERBOARD

The major concern when it comes to safeguarding lives against a catastrophic fire is the level of fire protection and the effectiveness of these protective measures.

Traditionally, designers follow a set of prescriptive Fire Code such as the Fire Code of the Philippines 2008 in applying the required fire protection for a building. Ethical design practices and the integrity of those designs are highly dependent on a robust testing system, coupled with a supply of fire-rated components that forms the fire-rated partition.

USG Boral is proud to say that our fire-rated systems are listed and certified to Underwriters Laboratories Inc. (UL) systems. The systems are not only recognised worldwide but also form part of fire containment systems that passed stringent quality control processes.

By having this certification, designers and architects are provided with a superior fire-rated system, assured of compliance to systems which are routinely subjected to UL’s audit process. This safeguards the interest of USG Boral’s clients and gives the additional peace of mind to know that the UL systems perform to its claim when installed to applicable codes and standards.

Having a listed system or listed individual product(s) is a shorthand way of saying that a company is authorized to use the UL Listing Mark on products such as USG Boral’s Type X Fire-Rated Plasterboard or metal studs that are in compliance with UL’s requirements.

INSTALLATION DETAILS

Installation

Vertically applied gypsum board shall have the edges parallel to framing members. Horizontally applied gypsum board shall have the edges at the right angles to the framing members. Intermediate vertical framing members are those between the vertical edges or ends of the board.

Unless otherwise stated in the detailed description of the individual system joints shall be staggered as follows:

a. Horizontal butt joints on opposite sides of a partition in single layer applications shall be staggered not less than 305mm (12").

b. Horizontal butt joints in adjacent layers on the same side of a partition in multilayer applications shall be staggered not less than 305mm (12").

c. Vertical joints on opposite sides of a partition in single layer applications shall not occur on the same stud.

When a fire-resistance-rated partition extends above the ceiling, the gypsum board joints occurring above the ceiling need not be taped and fasteners need not be covered when all of the following conditions are met.

a. The ceiling is part of a fire-resistance-rated floor ceiling or roof ceiling system;

b. All vertical joints occur over framing members;

c. Horizontal joints are either staggered 610mm (24") o.c. on opposite sides of the partition, or are covered with strips of gypsum board not less than 152mm (6") wide; or the partition is a two-layer system with joints staggered 406mm (16") or 610mm (24") o.c.; and

d. The partition is not part of a smoke or sound control system.

Where joint treatment is discontinued at or just above the ceiling line, the vertical joint shall be cross-taped at this location to reduce the possibility of joint cracking.

Metallic outlet boxes shall be permitted to be installed in wood and steel stud walls or partitions having gypsum board facings and classified as two hours or less. The surface area of individual boxes shall not exceed 103 square cm (16 square inch). The aggregate surface area of the boxes shall not exceed 645 square cm (100 square inch) in any 9.29 square meter (100 square feet). Boxes located on opposite sides of walls or partitions shall be in separate stud cavities and shall be separated by a minimum horizontal distance of 610mm (24"). Approved nonmetallic outlet boxes shall be permitted as allowed by local code. Installing outlet boxes in the sound control system may reduce the STC.

A vapor retarder shall be permitted to be added to any fire-resistance-rated system.

Unless otherwise specified in the detailed description, the generic steel studs and runners used in non-load-bearing walls and partitions in this Manual were fabricated from flat steel having a base metal thickness of not less than 0.45mm (0.0179") and have a return lip dimension of not less than 4.8mm (3/16")

Note: Consult the steel stud manufacturer for performance data and recommendations

before substituting proprietary steel studs that either are fabricated from steel having a

base metal thickness of less than 0.45mm (0.0179") have a return lip dimension less than

4.8mm (3/16").

Greater stud sizes (depths) shall be permitted to be used in metal or wood-stud systems. Metal studs of heavier gauge than those tested shall be permitted. The assigned rating of any load-bearing system shall also apply to the same system when used as a non-load-bearing system. Indicated stud spacings are maximums. Heavier gauge studs or closer stud spacing may reduce the STC. Greater stud depth may improve the STC.

Additional layers of Type X or regular gypsum panels shall be permitted to be added to any system. Additional layers of gypsum board may improve the STC.

When not specified as a component of a fire-resistance rated wall or partition system, cementitious backer units and/or wood structural panels shall be permitted to be added to one or both sides. Such panels shall be permitted to be applied either as a base layer directly to the framing (under the gypsum board), as a face layer (over the face layer of gypsum board), or between layers of gypsum board in multilayer systems. Where such panels are applied under the gypsum board or between layers of gypsum board the length of the fasteners specified for the attachment of the gypsum board applied over the panels shall be increased by not less than the thickness of the panels. Fastener spacing for the gypsum board and the number of layers of gypsum board shall be as specified in the system description.

When not specified as a component of a fire-tested wall or partition system, either faced or unfaced mineral fiber, glass fiber, or cellulose fiber insulation of a thickness not exceeding that of the cavity depth shall be permitted to be added within the stud cavity. Adding insulation may improve the STC.

Vertically applied gypsum board shall have the edges parallel to framing members. Horizontally applied gypsum board shall have the edges at right angles to the framing members. Intermediate vertical framing members are those between the vertical edges or ends of the board.

Two strips of 15.9mm (5/8") Type X gypsum panel products applied to the back of one of the studs with 41mm (1 5/8") Type S drywall screws 610mm (24") o.c. Horizontal joints offset 610mm (24") between strips. Gypsum strips are the same width as the stud depth and extend the full height of the wall with a 15.9mm (5/8") space between the back of the second strip and the back of the opposite stud. Gypsum panel products applied to the faces of the studs as specified in the listing for the one-hour fire-resistance-rated wall or partition with a 12.7mm (1/2") control joint opening centered over the gypsum panel strips. Gypsum panel ends or edges on one side of the control joint attached to one stud and gypsum panel ends or edges on the other side of the control joint attached to the second stud. A 12.7mm (1/2") metal or vinyl control joint accessory stapled to the wall on each side of the control joint opening. (NLB)

This control joint protection method is intended for use in any one-hour fire-resistance-rated non-load-bearing steel C-stud system in this Manual having a single row of studs. The wall system shall be constructed of the materials and in the manner described in the individual GA File Number.
