Isocell Airstop Diva Forte Vapour Barrier

£194.95 (GBP)

Variable Control Membrane

A vapour-diffusion/permeability variable control membrane for use in the air-tight layer. Airstop Diva Forte reacts to ambient humidity. In the dry-room climate of winter months the Sd-value rises to 20m. When there is sufficient insulation the moisture behind the vapour barrier increases and the Sd-value sinks to 0.2m. This enables a high degree of drying out of the moisture diffusion into the construction during the winter months.*
