Edge Overlapping


Fibre Reinforced Polyester (FRP) industrial roofing materials are generally designed to match the profile of the main roof and cladding products to be used on any project. The following considerations are important in the design and general support of FRP profiles.

Edge Installation

Alsynite Industrial FRP sheet is designed to lap over, and be supported by the main roofing material on both edges in accordance. The following drawings show typical examples of common profiles. Note all profiles should be supported at both edges.


The overlapping of single layer FRP sheet should lap over the main roof material at least 300 mm and to be sealed with 2*200 sealing washer at both ends.
