Verified by manufacturer 1 day ago
DN 70
DN 70
A thermally-insulated rainwater outlet with vertical spigot.
Application
For use with Bauder bituminous waterproofing membranes when connecting to conventional gravity drainage systems.
- DN70 is also used as part of Bauder’s blue roof system.
Designed to be used in warm, cold, and inverted roof scenarios.
Spigot designed to fit standard 75 mm (DN 70) and 160 mm (DN 150) pipework.
Description
A thermally-insulated, cast polyurethane rainwater outlet with vertical spigot giving thermal continuity. The outlet comes with a pre-attached bituminous flange to ensure waterproofing integrity between the outlet and membranes.
The BRE Certified (report no. HPR357-303748) high thermal value of the rigid foam body prevents condensation from forming on the underside of the outlet body. Outlet has a flow rate of 7.1 (70DN) and 7.2 (150DN) L/s based upon requirements of BS EN 12056:3:2000.
Where a warm roof system is specified, a separate extension piece will need to be ordered to maintain thermal integrity. This is available with a spigot length that can range from 60 to 220 mm according to the insulation thickness specified.
A separate 60-mm thick extension unit housing can also be ordered to accommodate the extension piece to save having to cut insulation on site to suit.
Also available as a DN 100 outlet (specified separately).
