Proctor SmartVap 100 Air barrier with variable vapour diffusion resistance

Product Description

ProctorPassive SmartVap 100 (SmartVap) is a two layer AS4200.1 compliant light duty air barrier and variable vapour diffusion resistance retarder.

Applications

When installed as a continuous layer, SmartVap will form an air tight layer, improving the efficacy of ventilation systems and thermal efficiency of the building enclosure. The effective management of air and vapour passage through wall, ceiling and floor assemblies can help protect the building fabric and insulation from condensation and related problems such as mould, timber rot, corrosion and loss of thermal resistance.

SmartVap should not be used on the exterior side of insulation in cold and temperate climates as an alternative to a vapour permeable sarking, where there is a risk that condensation will form on the interior face of the retarder.

Variable vapour diffusion resistance

The functional layer of SmartVap is a polyamide film. Such films passively adjust vapour diffusion resistance depending on the humidity where located. The polyamide absorbs water vapour from the air, opening the molecular pores thus adjusting vapour diffusion resistance according to ambient humidity conditions.
