The GSE Integration Flexalu Waterproofing Strip is designed for professional solar installers and homeowners looking for a reliable, lead-free sealing solution for roof-integrated mounting systems. Its primary benefit is providing a robust, watertight barrier that conforms effortlessly to complex roof textures, though its 330mm width may require careful planning when overlapping on steep or irregular pitches.

It is highly versatile and works on most slate, tile, and metal roof profiles due to its high malleability.
No, it is manufactured from high-quality lead-free aluminium.
The material can be easily cut using standard heavy-duty snips or shears.
While it is designed for GSE integration, it acts as a universal flashing strip and can be used for general roof sealing tasks where flexible flashing is required.
The black finish is designed for outdoor durability and weather resistance, though like all exterior materials, it will perform best when installed in accordance with standard roof flashing practices.
Ensure the strip is pressed firmly into the roof contour and check that it is properly overlapped by mounting components or flashing clips.
Use a rounded wooden block or rubber mallet to gently tap the material into the crease, ensuring you do not over-stretch or tear the aluminium.
To install, unroll the necessary length and position the strip over the gap between your GSE mounting system and the roof covering. Gently mold the aluminium by hand or with a rubber mallet to conform to the contours of the tile or metal profile. No specialized chemical adhesives are usually required for the strip itself, as its physical positioning under or over the mounting brackets secures it. For maintenance, periodically inspect the seal after extreme weather events to ensure that no lifting has occurred at the edges. Clean the surface periodically with water and a soft brush to remove dust or organic buildup.
