-
Assessment – A trained installer inspects your walls to make sure they’re suitable for cavity insulation.

Drilling Small Holes – Tiny holes are drilled at regular intervals along the exterior wall.
-
Injecting Insulation – The insulation material (usually foam or beads) is injected into the cavity between the bricks.
-
Filling the Cavity – The insulation spreads evenly, filling the gap and creating a thermal barrier that reduces heat loss.
-
Sealing the Holes – The small holes are carefully sealed, restoring the wall’s appearance.
-
Finished & Efficient – Your walls are now insulated, helping keep your home warmer in winter, cooler in summer, and more energy-efficient.
