GRP Floor Drain Trim

The GRP Floor Drain Trim is used wherever a flat roof's drainage design takes water vertically through the roof deck into a below-deck drainage system, rather than to a perimeter gutter or through-wall outlet. It forms a weathertight collar around the drainage outlet itself, sealing the critical junction between the flat GRP laminate and the vertical drain fitting below.

This detail is common on roofs with internal drainage layouts, including many commercial and industrial flat roofs where falls are designed to direct water to one or more central outlets rather than the perimeter. The trim laminates directly into the surrounding roof surface, maintaining continuity of the waterproof membrane right up to the edge of the drain. Compatible with GRP and other flat roofing systems; fixed using PU adhesive.

GRP roofing trims provide a practical, durable, and aesthetically pleasing solution for finishing fibreglass flat roofs and for other domestic and industrial applications. With their superior strength, resistance to the elements, and ease of installation, they help ensure a long-lasting, weather-tight roofing system. By combining functionality with modern design, GRP trims offer an excellent way to enhance the performance and appearance of fibreglass roofs.
