Free Cavity Wall Insulation from S6Energy

Most homes built after the 1940s have a gap, or cavity, between the inner and outer walls. This air space was originally designed to prevent moisture from seeping into the inner walls. However, it also acts as a heat escape route, allowing precious warmth to leak during colder months.

Here’s where cavity wall insulation comes in. This process involves filling the cavity with a special insulating material, like mineral wool, rockwool, or polystyrene beads. This creates a thermal barrier, trapping heat inside your home and keeping the cold air out.
