The open cell insulation allows moisture laden air within the attic to permeate through it where it will then pass into the outside environment through gaps and through roof tiles. This combats the buildup of "cold wet air" within the roof which would lead to mold growth and timber rot.
Insulation that is sprayed in buildings protects against moisture, which provides the benefit of reducing the chance of harmful mold and mildew. Eliminating mold growth reduces the likelihood of rotting wood in a home, and allergic reactions to mold spores.
Closed cell spray foam insulation is used in commercial, agricultural, and industrial applications.
Closed cell spray foam is easily applied to any metal concert or wooden surface. Unlike open cell spray foam, closed cell foam does not 'breathe' is rigid and dense when applied and expands much less than open cell.
When applied to asbestos roofing it helps encapsulate the asbestos forming an airtight seal which prevents the cancerous fibres escape.
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.
