AIRSTOP DIVA FORTE Vapour Barrier

Airstop Diva Forte Variable/Intelligent Membrane. Airstop Diva Forte reacts to ambient humidity. During the winter months the pores of the membrane decrease in size, preventing hot, moist, heated air from passing through the membrane into the insulation, therefore ensuring the effectiveness of the insulation and protecting your structure from damage due to excessive moisture. During the summer months (drying-out months), due to ambient humidity and temperatures, the pores of the membrane increase in size, therefore allowing any potential moisture within the structure, to dry back out towards the inside of the dwelling, hence preventing possible mould and rot within the structure. This process is crucial for exterior elements which are non-vapour diffusing or restrict the drying out of moisture to the exterior, such as felt-torched or water proofed flat roofs, pitched roofs with asphalt shingles, and green roofs. The variable vapour permeability of Airstop Diva ranges from 0.2 to 20, offering the highest protection against moisture related damages on the market.Air-Sealing with: Airstop Flex Adhesive Tape, Airstop Adhesive Tape, Airstop Sealant Sprint.
