Cavity Wall Insulation

Do you really need cavity wall insulation? If your home was built between 1924 and 1982, then the answer is probably going to be a yes.

A cavity wall is made of two layers of masonry bricks with a gap of at least 50mm in between. The cavity wall design with masonry bricks was chosen for its damp-proofing properties, but doesn't provide great insulation. It wasn't until the early 1980s that Building Regulations specified that properties with a cavity should be filled. So if your home was built between those dates, you really should take advantage of the cavity wall insulation grants that may well be due to you.

Cavity wall insulation can prevent up to 35% of heat escaping through your walls. In monetary terms, you could be looking at savings of up to £145 a year for a typical family home. You can also cut your carbon emissions by up to 610kg a year. If you're eligible, the whole cost of cavity wall insulation could be paid by a government grant. You'll also get a 25-year CIGA guarantee from the Certified Insulation Guarantee Agency.
