Plylok® is a thermal insulation board for use in warm flat roofs under traditional bituminous waterproofing and single-ply waterproofing membranes.

Plylok® consists of an insulation board bonded to a 6mm plywood top layer. It boasts high compressive strength and dimensional stability meaning it’s the ideal choice for contractors and installers for both new build and refurbishment projects.

Our Plylok® is CCPI verified, as noted in the verification marking below:
