Description:

The GRP Internal Drain Outlet is designed to efficiently channel rainwater through the roof deck into standard downpipes, making it ideal for flat roof drainage systems in fibreglass or polyurethane roofs.

Each outlet comes with a fibreglass mesh flange for perfect bonding to the roof membrane, ensuring a seamless and watertight connection. The polypropylene flange has knurled surfaces to enhance adhesion with liquid waterproofing materials, while the upper spigot steps capture and direct infiltration water into the outlet.

Available in 50mm, 75mm, 82mm, and 100mm diameters, these internal outlets provide a reliable and durable solution for both professional roofing contractors and DIY applications.
