Cavity Wall Insulation
Cavity Wall Insulation Grants are available to completely cover the cost of installing Cavity Wall Insulation. Up to 35% of the heat lost in your home escapes through the walls. Cavity Wall Insulation will help to prevent this heat loss and save you money on your heating bills. It is also a little known fact that Cavity Wall Insulation has the opposite effect in the summer by keeping you cooler.



What Is Cavity Wall Insulation?
In most houses built after the 1920s, the external walls are made of two layers with a small air gap or 'cavity' between them. If your home has unfilled cavity walls, a considerable portion of your heating bills will be spent warming the air outside.


Injecting the gap between the two walls of a house with an insulating material decreases the amount of heat escaping through the walls. Cavity Wall Insulation is quick, clean and FREE or inexpensive to install. It is injected into the cavity from the outside, typically taking two or three hours. All cavity wall installations are backed by a 25 year independent guarantee from CIGA, The Cavity Insulation Guarantee Agency.
