WALLTITE®
Spray Foam Insulation

Refurbished masonry wall insulation (timber frame)

WALLTITE® can be applied directly onto a solid masonry wall, between 90mm or 140mm timber studs, without the need for traditional adhesion promoters or mechanical fixings.

Mechanical and electrical services can be fixed between the foam and the plasterboard.

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.
