How to Install Cavity Wall Insulation

Modern built houses, from the 1970s and 1980s onward, are likely to have a cavity built into the walls. This is a gap between two layers of bricks. More modern homes by standard have insulation built into the cavity, whereby a thick piece of usually spun glass insulation is placed between the cavities. Before the 1990s houses often didn’t have this insulation placed during the build. Installing Cavity wall insulation is cheap and very effective. It involves blowing insulation material into the cavity of your walls, resulting in your inner wall no longer taking heat away from the building.
