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.
