Cavity Wall Insulation

Cavity wall insulation is one of the most cost effective ways of reducing heat loss in your home. Up to 35% of heat can be lost through the walls of your home.

Cavity wall insulation is a simple solution which can reduce heat loss in your walls by up to 60%. This could save you up to $350 (£200 GBP) per year on a your heating bills, if your home is currently poorly insulated. The cost of installing cavity wall insulation should be recovered within 5 years from the savings in your heating bills.

You first need to check that your walls are suitable for cavity wall insulation. Cavity walls are at least 12 inches (30cm) thick and comprise an outer and inner wall separated by a air gap. If you are unsure then contact a cavity wall specialist.

It's well worth checking to see if you are eligible for a grant. Government grants are available in many countries, to help pay the cost of installing cavity wall insulation.
