Drip Roofing Trims

They are used at the lowest point of the roof and fitted to the edge of the roof which allows drainage into the gutter.

Raised Edge Trims

Raised Edge Roofing Trims or ‘B’ Roofing Trims are used to keep water on the roof whilst directing it to the lowest point. This can be an outlet or a drip.

The wall fillet GRP Roofing Trims are used where the fibreglass flat roof butts again an existing wall to create a 45-degree angle which will redirect rainwater from the wall to the roof.

Internal and External Trims

The AT195 Internal trim is used wherever the laminate needs to cover an area which continues perpendicular to another laminated surface. The AT195 External Trim is supplied with a high-adhesion finish on its outer fascia and is mainly used for capping applications.
