GRP Flat Sheet Roll 300mm

The GRP flat flashing trim is a versatile flat section designed for cladding surfaces prior to top coating, and is ideal for use where a pitched roof meets a flat roof surface. It should be fixed in place using PU trim adhesive and secured with pins before applying the matting.

Manufactured from Glass Reinforced Polyester, this trim forms part of a fully integrated flat roofing system engineered for both horizontal and vertical applications. It is suitable for use across a wide range of domestic and commercial projects, providing reliable, all-weather protection.

The trim is available in lengths of 5m, 10m, 15m or 20m, with a width of 300mm, and is made from durable GRP material. It is easy to install and offers a flexible solution for a variety of roofing details.
