Areas of application

AEROSANA FLEECE is a supplementary product for working with spray-on or brush-on seals from the AEROSANA VISCONN family.
It can be used to reliably cover cracks or joints that are wider than 3 mm (1/8") in the case of AEROSANA VISCONN or 20 mm (3/4") in the case of AEROSANA VISCONN FIBRE.

Installation instructions


AEROSANA FLEECE can be used on subsurfaces that are slightly uneven and/or structured. To achieve airtight and/or windtight installation, it is important that AEROSANA FLEECE is coated with AEROSANA VISCONN or AEROSANA VISCONN FIBRE on both sides in the area where it is in contact with the subsurface.
Recommendations for subsurfaces that AEROSANA VISCONN products can be used on can be found in the relevant application recommendations.
