WALLTITE® injection insulation
Used to reduce the heat loss of existing and new build cavity walls. Installed as a liquid through a pattern of 12mm pre-drilled holes it expands within the cavity to gently fill each void eventually setting as a rigid polyurethane high-density insulation.

WALLTITE® wall solutions
Cavity wall insulation
WALLTITE cavity wall foam insulation is used to reduce the heat loss of existing and new build cavity walls consisting of masonry innerand outer leaf construction. Installed as a liquid through a pattern of 12mm pre-drilled holes it expands within the cavity to gently fill each void eventually setting as a rigid polyurethane high-density insulation. WALLTITE seals the cavity thereby preventing air leakage. The increased airtightness effect adds to the systems already superior thermal performance helping to reduce energy bills and creating a more comfortable living environment. WALLTITE insulation is also used to restore the structural stability of existing cavity walls in which conventional wall ties have corroded and in new build and reform construction where its resistance to flood water is of importance. WALLTITE stabilises the wall by adhering to the inner surfaces of the cavity and providing a continuous structural connection between the two leaves. It has excellent resistance to driving rain and can be installed in all geographical exposure zones.

Preparation
Application
Timber frame insulation
WALLTITE foam insulation is spray applied directly between timber studwork onto the OSB at the required thickness. Ordinarily a 25mm cavity will remain between the insulation and vapour control layers to allow for services. WALLTITE guarantees additional support and stability for the whole of the timber frame construction. The resulting continuous insulation and air barrier system will provide a cleaner, healthier more comfortable environment. WALLTITE Polyurethane spray is hypo allergenic and so contains no fibres or dust and no noxious vapours. BASF WALLTITE is very quickly installed by Foam Master contractors sing specialist equipment.

Masonry wall insulation – steel stud
WALLTITE spray foam insulation can be applied directly onto a solid dry masonry wall, between steel studwork fixed floor to ceiling. This allows for a layer of WALLTITE to remain unbridged by studwork thereby helping to reduce u-values further. The foam will engage any light steel framework to provide a more solid, secure wall when compared to other insulation methods. Ordinarily a 25mm cavity will remain between the insulation and vapour control layers to allow for services. WALLTITE guarantees additional support and stability for the whole of the wall construction. The resulting continuous insulation and air barrier system will provide a cleaner, healthier more comfortable environment for any “hard to treat” home situation.

Masonry wall insulation – timber stud
WALLTITE spray foam insulation can be applied directly onto a solid dry masonry wall, between timber studwork either fixed directly to the wall or anchored floor to ceiling. The latter method allows for a layer of WALLTITE to remain unbridged by timber thereby helping to reduce u-values even further. Ordinarily a 25mm cavity will remain between the insulation and vapour control layers to allow for services. WALLTITE guarantees additional support and stability for the whole of the timber frame construction. The resulting continuous insulation and air barrier system will provide a cleaner, healthier more comfortable environment for any “hard to treat” home situation.
