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.

 

Features and benefits

  • Low thermal conductivity 
  • Adds structural strength prolonging the life of the building

Walltite full fill cavity wall insulation

Walltite Cavity Wall InsulationWALLTITE 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 Refurb

WALLTITE cavity wall foam insulation is ideal for restoring the structural stability and reducing the heat loss associated with existing cavity walls already partially filled with rigid board insulation.

Walltite is also ideal where the need to reduce air leakage is important. The insulation seals the cavity, does not settle or allow air to pass through. 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.
