GRP Rainwater Outlet – Internal (68mm Downpipe)

This GRP Rainwater Outlet is an internal fibreglass drainage outlet designed for effective rainwater removal from GRP flat roofing systems. It provides a reliable connection between the roof surface and a standard 68mm downpipe, ensuring efficient water discharge and long-term performance.

Manufactured from durable GRP (fibreglass), this outlet is compatible with fibreglass roofing membranes and is designed to integrate seamlessly into internal drainage layouts. Its construction offers excellent resistance to weather exposure and long-term wear, making it suitable for both domestic and commercial flat roofing applications.

The internal outlet design helps maintain a clean roof edge detail while directing rainwater efficiently into the drainage system. It is ideal for use in new installations as well as refurbishment projects where dependable internal drainage is required.

Designed for professional use, this GRP rainwater outlet supports proper roof drainage and helps reduce the risk of standing water on flat roofs.
