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

WALLTITE® cavity wall insulation.
Walltite full fill 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 partial fill cavity wall insulation
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.
Performance data

| Typical u-value post Walltite installation (assumes 60mm existing EPS board with 40mm Walltite) | 0.29 W/m2k |
| Thermal performance improvement in percentage terms | 75% |
| Airtight | Yes |
| Water resistant | Yes |
