Bauder Bitumen Vertical Outlet DN 70 & 150

A thermally insulated rainwater outlet with vertical spigot designed for use when connecting to conventional gravity drainage systems.

This robust product is manufactured as a one-piece rigid polyurethane foam body forming the integral sump and spigot. It is manufactured with an integrated SBS elastomeric bitumen connecting membrane fused to the outlet body during production and additionally secured with a non-obstructive clamping ring. This ensures full homogeneous sealing between the outlet unit and the Bauder waterproofing system, offering an installation process that is both simple and very secure.

A tough, but lightweight, polyamide domical leaf grille permits free flow of water, whilst preventing leaf litter or other debris from entering the outlet. This push-fit grille is easily removed to allow for maintenance. The domical leaf grille is supplied with the outlet and is used for the Extension Unit in warm roof constructions.

The outlet is available in two sizes, 70 mm and 150 mm, with the spigot designed to fit standard 75 mm and 160 mm pipework respectively.

Only to be used as part of a full Bauder Bituminous Waterproofing System.
