What is Cavity Wall Insulation?

Cavity wall insulation is a method of improving a building's energy efficiency by filling the air space (cavity) between the inner and outer layers of external walls. As described in the document, cavity walls became popular in construction after the 1920s

The insulation material, which can be mineral wool, polystyrene beads, or polyurethane foam, is injected into the cavity through small holes drilled in the outer wall. This process creates a barrier that traps warm air inside the building, reducing heat loss and improving overall thermal performance.

Cavity Wall Insulation Benefits

Installing cavity wall insulation offers significant advantages for homeowners. As stated in the document, about a third of all heat lost in an uninsulated home escape through the walls. By properly insulating cavity walls, you can dramatically reduce this heat loss, leading to lower energy bills and a more comfortable living environment.

Cavity wall insulation helps maintain a consistent indoor temperature, reducing the workload on heating and cooling systems. This not only saves money but also reduces your carbon footprint. Additionally, it can help prevent issues like condensation and mould growth by reducing the temperature difference between the inner and outer walls.
