Rubberseal Vapour Control
PROVAP S/A is a self-adhesive bituminous membrane that forms a barrier against vapour and gases. Consisting of a self-adhesive bituminous compound re-enforced by a composite aluminium foil with integral glass-fibre mat. The upper foil surface is polyester coated offering protection from alkalis and provides a surface on to which LIQUIFLEX PRO and most other polyurethane systems and adhesives will adhere.
The exceptionally high vapour resistance enables use in buildings with extreme internal conditions and high humidity such as sports halls, swimming pools, bathrooms, kitchens and wet industrial processes. Fast and easy installation achieves waterproofing of a roof structure prior to the installation of the insulation and waterproofing, providing a vapour barrier without the need for hot works or naked flame in application.
Suitable for use on most common substrates such as concrete, plywood/OSB and metal decks. The high integral strength of PROVAP S/A withstands puncturing from foot traffic when used on profiled metal decks.
