IKO Permaphalt is the result of extensive research and development, and the careful selection of polymers to provide improved performance in all flat roof specifications.

IKO 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.

IKO Permaphalt mastic asphalt is suitable for insulated warm roofs, un-insulated cold roofs and inverted/green roof configurations.
