Injected Cavity Wall Insulation

Contact us

A polyurethane (PUR) foam system can be injected into a cavity of a property via holes in the outer leaf producing insulation with excellent adhesive, structural and thermal properties. The product bonds the inner and outer leaves together thus eliminating, or even treating, the problem of wall tie failure.
