Cavity Wall Insulation

Cavity wall insulation fills the gap between the inner and outer walls of your home with insulating material. Around a third of heat lost in an uninsulated home escapes through the walls. The process involves drilling small holes in the outer wall and injecting insulation material, which is then sealed. Most installations are completed in a few hours with minimal disruption.
