Wall Fillets & Right Angle Trims

Wall fillet and right angle trims are used at internal junctions where a flat roof meets a vertical surface - typically at the base of a parapet wall or where the roof deck meets an upstand. They provide a smooth, pre-formed 90° transition that eliminates the sharp internal angle, allowing the GRP laminate or membrane to follow the junction cleanly without bridging or lifting away from the corner.

Two profiles are available: the D200, which provides a standard fillet angle suited to most domestic and commercial junctions, and the larger D260 for situations requiring a more substantial internal corner profile. Both are available in 1.5m and 3m lengths and are supplied in light grey GRP. Fixed using PU adhesive; bracing against the junction before the laminate is applied ensures the trim remains correctly positioned during installation.
