Airstop Diva + Fiber is a smart vapour control that

reacts to ambient humidity. A first class air barrier for

thermal insulation in roofs, walls and floors. During the

winter months the pores of the membrane decrease

in size, preventing hot, moist, heated air from passing

through the membrane from the warm side 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),

under certain conditions the pores of the membrane

increase in size at the right time 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 + Sd of 0.5 to 30 / 0.11 - 7 Perms , offers

one of the highest protection against moisture related

damages on the market. This reinforced membrane is

highly suitable for blown in insulation's.
