GRP Expansion Trim E280 – 110mm x 3m

The E280 Raised Ridge Roll is a universal GRP expansion trim designed for use on larger roofs, providing both a functional expansion joint and an attractive decorative finish. It can be used to simulate a traditional lead mop roll or installed over an expansion gap within the roof deck to maintain structural integrity and prevent cracking.

With a length of 3m, a width of 110mm, a raised height of 35mm, and an overall height of 125mm, it is suitable for roofs over 50m² where expansion gaps are recommended. In such cases, a 25mm gap should be formed in the roof deck boards, with the E280 trim fitted over the top using PU trim adhesive and pins to secure it before applying the GRP matting and resin.

Manufactured from high-quality Glass Reinforced Polyester, this trim forms part of a fully integrated flat roofing system suitable for both domestic and commercial applications. It delivers a seamless, durable, and weatherproof finish that performs reliably across a wide range of flat roof and vertical surface installations.

The E280 is compatible with C5 preformed closures and features a unique high-bond surface designed to work with roofing resin and topcoat without risk of delamination. It is flexible enough to accommodate uneven surfaces, pre-pigmented for convenience, UV stabilised for long-term performance, and designed for easy jointing.
