AIRSTOP DIVA+ VAPOUR RETARDER FABRIC-REINFORCED
Moisture-variable, fabric-reinforced vapour barrier for use in the air-tight layer. High back-drying potential with adequate sun exposure. See our product data sheet!
HIGH SD-VALUE RANGE
Is a moisture-variable vapour barrier for use in the air-tight layer. The functional membrane changes its diffusion resistance depending on the current humidity. During the winter months room atmosphere is generally dryer. The sd-value of the vapour barrier increases. This process results in the penetration of only a little water vapour into the construction and/or into the insulation. In summer, when there is sufficient solar insolation, the relative humidity behind the membrane is higher as a result of reverse diffusion. The water molecules are stored in the membrane. The sd-value sinks, causing more water vapour to escape from the construction and into the rooms and the building element becomes dryer.
FIELD OF APPLICATION
construction components with permeable and impermeable outer shell in new constructions and refurbishment
for wall, ceiling and roof
moisture-variable with a very high sd-value range
