POLYPIPE Manufacturer's Part Number: SV457.
POLYPIPE Soil & Vent Fitting - Square 457mm x 457mm Angled Roof Weathering Slate for Ø82mm/3'' & Ø110mm/4'' Soil Pipe, used for pitched roofs.
Where a soil pipe passes through a roof it must be weathered to prevent rainwater passing into the building along the pipe wall. This can be achieved by the use of a rubber/aluminium Roof Weathering Slate which can be dressed to the profile of the roof tiles or slates.
The Weathering Slate can be pushed over the top of the soil pipe ensuring that there are no sharp edges which could damage the rubber sleeve. The slate is aligned with the lower tiles. The base plate is dressed to the profile of the lower tiles with the side and upper tiles laid over the top of the base plate. On low pitched roofs, a single welt can be made to the lower edge of the base plate to provide extra strength. The base plate may be trimmed if required, provided that at least 150mm of weathering remains. If the roof slate is installed on a roof with interlocking tiles, boards or additional battens may be required underneath the weathering slate. The stack must pass through one only course.
A Weathering Apron (Collar) is placed over the stack and solvent welded into position directly above the weathering slate. To complete the installation, a Vent Terminal is solvent welded to the top of the stack.
Please note: Weathering Apron (Collar) and Vent Terminal are purchased separately.
