"Anti-overflow" roof drains are intended for drainage of flat roof covered with thermoplastic bitumen hydro-insulating membrane.

Using a sealing flange combined with a downpipe provides a tight roof drainage system. Made of special material 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.

A long outlet pipe enables installation in thick ceilings.

A funnel-shaped anti-overflow container prevents water from overflowing during the first strike of rain and increases the drainage capacity by 20% in relation to other drains of the same diameter.
