Flat Roof Outlet
Drain outlet is one of the best means of connecting to an outlet drain. Its dimensions conform to UNI EN 1451-1, and it fits to bell and spigot jointed pipes without using adhesive.
TOP drain flat roof outlets are particularly suited for use in low pitch roofs, under roof gardens, inverted roof systems and tiled roof areas. Fixing and fastening to the DuoPly membrane is by a threaded ring which allows for a compression seal when used with DuoPly Water Cut Off Mastic.
