Permaphalt is the result of extensive research and development, and the careful selection of polymers to provide improved performance in all flat roof specifications.
Permaphalt can be applied to form a continuous waterproof covering over flat, sloped or curved surfaces. It can be worked round pipes, roof lights and other projections to provide a completely seam free membrane.
Permaphalt mastic asphalt is suitable for insulated warm roofs, un-insulated cold roofs and inverted/green roof configurations.
