Filling the gap in your walls
Cavity wall insulation is fitted from outside in a few hours, with no mess indoors.
Before: heat escapes through the gap
Most homes built from the 1920s onwards have outside walls made of two layers with a gap, the cavity, between them. Left empty, the walls are where an uninsulated home loses much of its heat.
Step 1: small holes drilled from outside
Our installers drill a pattern of small holes through the mortar of the outer wall. Everything is done from outside, so there's no mess indoors.
Step 2: insulation blown into the cavity
Insulation is blown through each hole under pressure until the cavity is full, from the bottom of the wall to the top. Most homes are finished in a few hours.
After: the warmth stays in
The holes are filled to match the mortar, so you'd hardly know we'd been. The insulation slows heat passing through the wall, keeping your rooms warmer and your heating bills lower.
