"Extra-long 485" roof drains are intended for drainage of flat roofs covered with thermoplastic bitumen hydro-insulating membrane. Made of special material - IGOM.CE, that binds well with bitumen membranes, they are characterised by high resistance to UV radiation, ozone, and other atmospheric and chemical agents.

Due to refining additives, the roof drains maintain their flexibility and dimensional stability in a wide temperature range and provide short-time resistance to welding, enabling you to weld them directly to bitumen membrane. The sealing flange combined with a downpipe provides a tight roof drainage system. A long outlet pipe enables installation in thick ceilings.
