GRP Internal Fillet Corner (C3) – Pre-Formed Corner Trim for Seamless GRP Roofing

The GRP Internal Fillet Corner (C3) is a pre-formed, hot-pressed corner trim designed for a clean, professional finish where two fillet trims meet on a GRP flat roofing system. Engineered for durability and a perfect fit, this internal corner enhances both the look and watertightness of your fibreglass roof installation.

It’s quick to install and ideal for both residential and commercial flat roof projects, saving time on-site and ensuring a smooth, reliable finish.

Key Features:

✅ Precision Moulded – Hot-pressed for a consistent shape and fit
✅ Internal Corner Compatibility – Designed for junctions where two fillet trims meet
✅ Quick Installation – Fix with nails and PU adhesive; easy to bandage and finish
✅ Seamless Appearance – Use tissue bandage for a smooth, watertight joint
✅ Made from GRP – Long-lasting, weather-resistant and impact-resistant material

Trim Fitting Instructions:

Nail the corner to the deck at both ends and in the centre.
Seal joins between trims and corner using a thin line of PU adhesive.
Smooth the adhesive with a moist finger to seal the joint.
Bandage over the joint with fibreglass tissue for a flush finish.
