VAPOZINC is a structural mesh with a diffusion-open formwork membrane on the underside. It safely wicks away any moisture between the substructure and the roof covering and can be laid on wooden formwork as well as on large, non-moisture-compensating substrates such as wood-based materials or non-slip insulation. The vapour-permeable formwork membrane minimises the penetration of moisture during the construction phase and at the same time enables drying out in the roof due to its structure. VAPOZINC allows the construction to breathe. Waterlogging in the roof structure is reliably prevented with VAPOZINC. Roofing materials are safely and permanently protected from corrosion and rot.
