Through wall parapet drain for TPO membrane

Made of special material that binds well with TPO 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.

Can be used in horizontal drainage systems (directly outside of the building) as well as in vertical systems with a standard external downpipe using an elbow connector or a conical rainhead.

When installed horizontally, make sure the drain is pitched at a 3 - 5 degree angle.

Can be installed vertically at an attic.
