Cavity walls are named for the gap in-between their two wall layers. Cavity Wall Insulation involves filling the gap between your walls with the insulation material of your choice: mineral wool, polystyrene beads, or other foamed insulants.
Why should you insulate your cavity walls?
Uninsulated cavity walls can only retain about a third of the heat generated by your home’s central heating system, allowing up to £475 worth of heat to escape, every year.
