Aerosana Visconn/Aerosana Visconn Fibre is a highly flexible liquid-applied air barrier. As a water-based acrylic dispersion sealant, it can be brushed or sprayed on as a liquid film. Once dry it forms a seamless, elastic, airtight and humidity-variable membrane.

Aerosana Visconn adheres to many types of substrates and can seal gaps up to 3 mm wide and Aerosana Visconn Fibre can seal gaps up to 20 mm wide.

Aerosana Visconn/Aerosana Visconn fibre can be applied via airless paint sprayer, brush or roller and is supplied in 10-litre tins or 600 ml cartridges, the latter being for use with the bespoke Pro Clima Aerofixx sprayer/ sealant gun.

Features and benefits:

Passivhaus-certified airtightness component.
Speedy.
Versatile.
Permanently flexible.
The application can speed up airtightness installation significantly, especially in awkward retrofit areas around timber elements such as timber joist ends.
Once dried it has excellent elasticity giving a robust, long-term flexible airtightness layer which allows for movement.
Use to ensure airtightness at difficult or awkwardly shaped junctions around timber joists or wall plates.
Plasterboards can be dotted and dabbed onto masonry walls where the product has already been applied over.
Can be directly plastered over.

Broad area of application: Wall-to-floor junctions, window reveals, joist ends, doubled-up timber members with a small gap in between, pipe penetrations (especially when a pipe has already been installed, large masonry wall areas/building envelope).
