Material: Made from fibreglass-reinforced plastic, which is lightweight, durable, and weather-resistant.
Purpose:
o Forms edges, upstands, and junctions on GRP (fibreglass) flat roofs.
o Helps direct rainwater off the roof (e.g., through drip edges or gutter
details).
o Ensures a neat and professional finish to corners, perimeters, and
abutments.

Types:
o Drip Trims – for leading rainwater into gutters.
o Upstand Trims – for walls or edges where the roof meets a vertical
surface.
o Internal/External Corners – for joining trim pieces at corners.
