4 CONSIDERATIONS WHEN SELECTING ROOF OUTLETS The purpose of roof outlets is to provide effective drainage of rainwater. Selection of roof outlets is usually the responsibility of the specifying engineer conversant with the roof construction, roofing finish, drainage system and designated function such as a garden or parking. Some of the factors that should be considered when selecting roof outlets are: BUILDING REGULATIONS / STANDARDS National and local regulations must be complied with in matters concerning drainage of rainwater. ROOF CONSTRUCTION Roof outlets are not multi-purpose, versions are designed for use with specific types of roof construction. The depth of the structural slab, thickness and location of insulation, and the type and location of waterproofing membrane are factors to be considered. FLOW RATE The quantity and types of roof outlet to be used in a given application must be related to the roof area and expected volume of rainwater to be drained. Flow rate is the amount of water (litres/sec) a roof outlet will drain 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 filter buckets. Flow rates of Wade roof outlets have been established by full scale tests, at various heads of water. Results are shown on pages 2 to 29. THERMAL INSULATION To prevent condensation in roofs of heated buildings where the relative humidity may be expected to rise above 4%, it may be necessary to install additional insulation around roof outlet bodies. In applications subject to heavy snow or icing up, it may be desirable to include trace heating. APPEARANCE Whilst of pleasing appearance, gratings are designed to be relatively inconspicuous when installed. For areas where a better class of finish is required, some products are available made of nickel bronze. ACCESSORIES AND VARIATIONS Standard optional items are readily available, such as filter buckets to intercept debris, gravel guards, bearing pans to spread the load over a large area, and underdeck clamps to secure bodies. Custom made products can be manufactured for nonstandard applications. MATERIALS AND FINISHES Strength, corrosion resistance and appearance are important considerations when selecting roof outlets. LOAD RATING It is essential that roof outlets withstand expected loads. This Technical Handbook shows the load rating class for each grating 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 and workshops - not including light commercial vehicles or heavy wheel loads. PIPEWORK The type and size of pipework in a given installation is fundamental to the selection of roof outlets. Wade roof outlets can be connected to all pipework in general use; certain bodies are for direct connection to pipework, others require the use of spigot adaptors or proprietary couplings. 4

5 MATERIALS Materials and finish of Wade roof outlets, described below, are selected to provide lasting performance and to blend with surroundings. CAST IRON - BS EN 1561 Used for bodies, membrane clamping collars,extensions and spigot adaptors. A widely used metal in the drainage industry, its resistance to corrosion permits extended use under extreme conditions. Castings are coated with a high grade lacquer paint, applied by full immersion dip, to provide internal and external surface coverage. Paint will gradually wear off and is replaceable; oxidisation (surface rusting) is a natural process which does not weaken the material. DUCTILE IRON - BS EN Used only for gratings. A casting with the ductility of steel, yet with more than twice the tensile strength of. A zinc anti-corrosion coating is applied by sherardizing. STAINLESS STEEL - AUSTENITIC GRADE 34 Used for gratings, gravel guards, filter buckets and all fastenings. A corrosion-resistant metal containing significant amounts of nickel 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 14 Used for downspout nozzles. A cast alloy suited for finished areas where the rich, bronze colour complements the decor. NICKEL BRONZE - BS 14 Satin finish Used for gratings A cast alloy which will maintain its lustre when subjected to the abrasive polishing action of traffic. The satin finish produces a fine grain effect which blends well with walls and floors. POLYCARBONATE Used for domes A polycarbonate/abs blend which offers durability, high impact strength and long term resistance to ultraviolet light. PVC Used for body versions for use with PVC single ply membranes. This material enables a waterproof joint to be produced on site. ABS Used for spigot adaptors CARE AND MAINTENANCE The products require the minimum of maintenance, but periodic inspection should be carried out to ensure that roof outlets are free from gravel, leaves and other debris which could impair the performance of the system. Cast iron parts should be repainted every five years. 5

6 Various Wade roof outlets are installed in the terminal buildings at Manchester Airport WB2 Series roof outlet for use in a cold roof. 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.

WC224Z roof outlet with WG12 underdeck clamp and WT13 spigot, in a warm roof with single ply membrane. Parapet s Wade offers a range of parapet outlets with reversible, PVC body, to provide horizontal or vertical threaded outlet, with grating options.

26 FLOW RATES Flow rate testing a WB224 roof outlet Flow rates of Wade roof outlets have been established by full-scale tests. The values shown in graphs on pages 2-29 are 5% of such tests. The graphs show, for given heads of water, flow rate (l/s) and area drained (m 2 ) at a rainfall rate of 5mm/h** or.21 l/s per m 2.* *Rainfall Rate - BS EN l/s per m 2 equates to 5mm/h, as previously recommended in BS636 (superseded by BS EN :2). BS EN uses rainfall charts which provide more localised data given in l/s per m 2. To calculate the area drained [A] for a specific rainfall rate [R] (l/s per m 2 ) use the following formula..21 A(m 2 ) = x a (m l/s per m 2 ) R (l/s per m 2 ) (a: area drained, obtained from appropriate graph.) ** Rainfall Rate - BS 636 5mm/h has been used as previously recommended in BS 636 (withdrawn September 2). Area drained [A] at a different rainfall rate [R] can be calculated by using the following formula. 5 A(m 2 ) = x a (m 5mm/h) R (mm/h) (a: area drained, obtained from appropriate graph.)

30 INSTALLATION GUIDELINES General The design of the layout of roof outlets should be in accordance with the recommendations given in BS EN 1256:3. Wade roof outlets should be placed at the roof low points to allow efficient flow of water to the outlets. Illustrations of typical installations are given in each section of this handbook. 1. Check Dimensions Prior to installation, check height of components to ensure compatibility with roof build-up, making allowances for the membrane thickness. 2. Fit Spigot. Check Where applicable, screw spigot into body, using a suitable sealant to ensure the joint is watertight. Position body in roof deck and ensure that outlet is accessible for pipework connection. 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. 4. Dress Membrane and Clamp Refer to membrane manufacturer s instructions. Prepare flange of body with suitable primer and apply membrane, dressing over flange and into sump of body. Position membrane clamping collar and secure to body using fixings supplied. 5. Install Insulation Install any intermediate roof build-up (e.g. insulation) around outlets. 6. Fit Grating. Apply Finish Fit dome/grating using height adjustment where applicable to ensure grating is flush with roof finish. Apply roof finish around grating. 3
