GRP bonding strips are used where two walls meet, and different roof finishes are present. GRP bonding strips are particularly useful when reroofing and provide a watertight junction above the party wall where roofing materials change.

Eaves trays, or eaves protectors, are manufactured from GRP or PVC, provide a long-lasting and durable form of protection to prevent structural damage. If timber is exposed to water or moisture over a long period, mould, damp and rot can occur.

Eaves trays, or eaves strips, are the first sheet laid along the eaves of a roof and bridge the gap between the eaves and the gutter system. The eaves tray or eaves strip then directs any rainwater into the gutter and prevents the water from affecting the eaves of the building.
