TPE Round Through-Wall / Parapet Outlet (63-125mm)

This round through-wall roof drain is designed to provide dependable horizontal rainwater discharge from flat roofing systems. Manufactured from durable thermoplastic rubber (TPE), it remains flexible and resilient in cold conditions, with temperature performance down to approximately –40°C.

Suitable for use with bituminous waterproofing membranes, the outlet features an angled body with a round outlet spigot designed to pass through parapet or wall constructions. The spigot is supplied at 500mm in length and can be cut to size on site, allowing flexibility during installation.

The flange incorporates an embossed detailing zone that enables torch-applied membranes to bond effectively with the surrounding waterproofing layers, helping to form a secure and durable watertight connection. Integrated sealing features within the outlet body are designed to reduce the risk of water tracking or infiltration once installed.
