BASF Walltite Cavity Wall Insulation

BASF Walltite Cavity Wall Insulation West Sussex

Masonry cavity wall insulation

WALLTITE® is used to restore the structural stability and reduce the thermal transmittance of existing cavity walls, with masonry inner and outer levels, in which the conventional wall ties have corroded. It is also used in new construction where its superior thermal performance and resistance to flood water is of importance. It has excellent resistance to driving rain and can be installed in all geographical exposure zones.

WALLTITE® is also ideal where the need to reduce air leakage is important. The foam seals the cavity, does not shrink or allow air to pass through it, therefore air leakage through the cavity can be reduced to zero. WALLTITE® stabilises the wall by adhering to the inner surfaces of the cavity and providing a continuous structural connection between the two leaves.

The system can also be used on random stone walls that form uneven cavities.
