What Is Cavity Wall Insulation?
In most houses built after 1924, 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.
Filling 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 with grants or inexpensive to install privately. It is blown 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.
Did you know that around a third of all the heat lost in an un-insulated home is through the walls? Insulating cavity walls reduces heat loss and can save you around £115 a year on your fuel bills.
How does it work?
Cavity wall insulation slows down the rate at which thermal heat escapes, keeping as much of it as possible inside your home for as long as possible. The cavity wall Insulation makes it much more difficult for heat to pass through your walls by filling up the cavity with a material with lots of air pockets in it. These pockets greatly reduce what is known as your walls' U value - which is a measure of how quickly they lose heat - from around 1.5 to 0.5 W/m2K . The lower the U value, the slower heat is lost - and the less energy you need to keep your home warm. You may on occasions also see references to an R-value. This is a measure of thermal resistance and is the inverse of a U-value - the higher a U-value is the lower the R-value is.
