Vapourstop is designed for use as a vapour barrier in conjunction with the Marley Waterproofing range of high performance roofing membranes. It provides a permanent water vapour resistance to protect the insulation and on metal decks can provide resistance to wind uplift and protection against deck corrosion.

Vapourstop consists of a thick, impervious aluminium core reinforced with hessian and coated with bitumen.
