The purpose of roof outlets is to provide effective drainageof rainwater. Selection of roof outlets is usually the

responsibility of the specifying engineer conversant with theroof construction, roofing finish, drainage system anddesignated function such as a garden or parking.Some of the factors that should be considered when selectingroof outlets are:

BUILDING REGULATIONS / STANDARDSNational and local regulations must be complied with inmatters concerning drainage of rainwater.

ROOF CONSTRUCTIONRoof outlets are not multi-purpose, versions are designed foruse with specific types of roof construction. The depth of thestructural slab, thickness and location of insulation, and thetype and location of waterproofing membrane are factors tobe considered.

FLOW RATEThe quantity and types of roof outlet to be used in a givenapplication must be related to the roof area and expectedvolume of rainwater to be drained.Flow rate is the amount of water (litres/sec) a roof outlet willdrain at a given head; it is influenced by several factors:grating free area, sump capacity, design of the roof outlet,outlet size, and accessories such as gravel guards and filterbuckets.Flow rates of Wade roof outlets have been established by fullscale tests, at various heads of water. Results are shown onpages 27 to 29.

LOAD RATINGIt is essential that roof outlets withstand expected loads. ThisTechnical Handbook shows the load rating class for eachgrating or roof outlet assembly, based on BS EN 1253, as follows:

K3 - Areas without vehicular traffic, such as balconies,terraces and roof gardens.

L15 - Areas with light vehicular traffic.

M125 - Areas with vehicular traffic, such as car parks, factories andworkshops - not including light commercial vehicles or heavy wheel loads.

PIPEWORKThe type and size of pipework in a given installation isfundamental to the selection of roof outlets. Wade roofoutlets can be connected to all pipework in general use;certain bodies are for direct connection to pipework, othersrequire the use of spigot adaptors or proprietary couplings.

THERMAL INSULATIONTo prevent condensation in roofs of heated buildings wherethe relative humidity may be expected to rise above 40%, itmay be necessary to install additional insulation around roofoutlet bodies. In applications subject to heavy snow or icingup, it may be desirable to include trace heating.

APPEARANCEWhilst of pleasing appearance, gratings are designed to berelatively inconspicuous when installed. For areas where abetter class of finish is required, some products are availablemade of nickel bronze.

ACCESSORIES AND VARIATIONSStandard optional items are readily available, such as filterbuckets to intercept debris, gravel guards, bearing pans tospread the load over a large area, and underdeck clamps tosecure bodies.Custom made products can be manufactured for non-standard applications.

MATERIALS AND FINISHES Strength, corrosion resistance and appearance are importantconsiderations when selecting roof outlets.

CONSIDERATIONS WHEN SELECTING ROOF OUTLETS

4


Materials and finish of Wade roof outlets, described below, areselected to provide lasting performance and to blend withsurroundings.

CAST IRON - BS EN 1561

Used for bodies, membrane clamping collars,extensionsand spigot adaptors.

A widely used metal in the drainage industry, its resistance tocorrosion permits extended use under extreme conditions.Castings are coated with a high grade lacquer paint, appliedby full immersion dip, to provide internal and external surfacecoverage. Paint will gradually wear off and is replaceable;oxidisation (surface rusting) is a natural process which doesnot weaken the material.

DUCTILE IRON - BS EN 1563 + 1564

Used only for gratings.

A casting with the ductility of steel, yet with more than twicethe tensile strength of cast iron. A zinc anti-corrosion coatingis applied by sherardizing.

5

MATERIALS

CARE AND MAINTENANCEThe products require the minimumof maintenance, but periodicinspection should be carried out toensure that roof outlets are freefrom gravel, leaves and otherdebris which could impair theperformance of the system. Castiron parts should be repaintedevery five years.

STAINLESS STEEL - AUSTENITIC GRADE 304

Used for gratings, gravel guards, filter buckets and allfastenings.

A corrosion-resistant metal containing significant amounts ofnickel and chromium.

GALVANISED MILD STEEL

Used for adjustable bearing pans and raising tubes.

A cost effective, corrosion resistant material.

CAST ALUMINIUM - LM6

Used for parapet gratings.

An alloy chosen for its chemical resistance and durability.

GUNMETAL - BS 1400

Used for downspout nozzles.

A cast alloy suited for finished areas where the rich, bronzecolour complements the decor.

NICKEL BRONZE - BS 1400 Satin finish

Used for gratings

A cast alloy which will maintain its lustre when subjected to theabrasive polishing action of traffic.The satin finish produces a fine grain effect which blends wellwith walls and floors.

POLYCARBONATE

Used for domes

A polycarbonate/ABS blend which offers durability, highimpact strength and long term resistance to ultraviolet light.

PVC

Used for body versions for use with PVCsingle ply membranes.

This material enables a waterproof joint to beproduced on site.

ABSUsed for spigot adaptors


Wade designs and manufactures roof outlets for use with specific types of roof

construction, worldwide.

This Technical Handbook includes ranges of standard products which are generally

available ex stock.

Custom made products and accessories can be designed to suit particular

applications. Please contact our Technical Services Dept for details.

On site the raising tube can be easily slide-positioned through thebearing pan to suit any insulation thickness from 20mm to 135mm.When the required height is achieved, the tube is secured to thebearing pan using the self-tapping screws provided. The bearing pan isdesigned to be fixed to the deck/slab, so an underdeck clamp is notnecessary.

Load-bearing applications Non Load-bearing applications

A warm roof is constructed such that thewaterproofing membrane is above insulationwhich is laid on the roof deck.

All bodies have a generous flange, essential for bondingasphalt or other membrane. All fixings are of stainlesssteel.

LOAD RATINGThe load rating class is shown for each roof outlet;explanation of classes is given on page 4.

FLOW RATEArea drained (m2) is given for each roof outlet at a headof 35mm and rainfall rate of 75mm/h or 0.021 l/s per m2.Graphs comparing the flow rate performance of roofoutlets at different heads are shown on pages 28 and 29.

Flow rates of Wade roof outlets have been established by full-scaletests. The values shown in graphs on pages 27-29 are 75% of suchtests.The graphs show, for given heads of water, flow rate (l/s) and areadrained (m2) at a rainfall rate of 75mm/h** or 0.021 l/s per m2.*

** Rainfall Rate - BS 636775mm/h has been used as previously recommended in BS 6367(withdrawn September 2000).Area drained [A] at a different rainfall rate [R] can be calculated byusing the following formula.

A (m2) = 75 x a (m2 @ 75mm/h)R (mm/h)

(a: area drained, obtained from appropriate graph.)

For assistance please contact our Technical Services Dept.

Flow rate testing a WB224 roof outlet

FLOW RATES

*Rainfall Rate - BS EN 12056 -3

0.021 l/s per m2 equates to 75mm/h, as previously recommended inBS6367 (superseded by BS EN 12056-3:2000).BS EN 12056-3 uses rainfall charts which provide more localiseddata given in l/s per m2.To calculate the area drained [A] for a specific rainfall rate [R] (l/sper m2) use the following formula.

A (m2) = 0.021 x a (m2 @ 0.021 l/s per m2) R (l/s per m2)

INSTALLATION GUIDELINES

1. Check Dimensions

Prior to installation, check height of

components to ensure compatibility with

roof build-up, making allowances for the

membrane thickness.

3. Install Body

Install body such that flange is flush or

sub-flush with roof deck. Ensure body is

fixed securely, either bonded or clamped

to the deck if not cast-in.

Note: Membrane flange level is

determined by roof build up.
