Spray Foam Insulation

Refurbished masonry wall insulation (independent metal frame)

WALLTITE® can be applied directly onto a solid masonry wall, around the frame/channel brackets, without the need for traditional adhesion promoters or mechanical fixings.

This method greatly reduces repeating thermal bridges through the insulation caused by either timber studs or metal frames.

The resulting continuous insulation and air barrier system will provide a permanent solution for any ‘hard to treat’ solid wall situation.


WALLTITE® has undergone various performance tests. Certificates are available on request.
