How much heat disappears through your walls?

Cavity wall insulation is a fantastic way to significantly reduce the amount of energy you need to heat your home. Between 2002 and 2005 around 800,000 households installed cavity wall insulation. It is estimated that this will have saved nearly 400,000 tonnes of CO2, enough to fill the new Wembley Stadium 47 times.

In most houses built after the 1920's, 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 slice of your energy bills will be spent heating the air outside.  Quite simply - insulation saves you money and keeps you warmer when the evenings get chilly.

How cavity wall insulation works

Filling the gap between the two walls of the house with an insulating material massively decreases the amount of heat which escapes through the walls. Cavity wall insulation will help to create a more even temperature in your home, help prevent condensation on the walls and ceilings and can also reduce the amount of heat build up inside your home during summer hot spells.

did you know?If all the houses with unfilled cavity walls had them filled with cavity wall insulation, the energy saved could heat a staggering 1.4 million homes each year.

How is it installed

Cavity wall insulation is quick, clean and relatively inexpensive to install. It's injected into the cavity from the outside taking between two and three hours in a three bedroom semi-detached house.

what our customers say

"I was delighted with the service from start to finish and both the people on the phone and the workmen who did the job were polite and helpful at all times. The insulation installation was done quickly and efficiently and I can't fault the workmanship, everything was cleared away after the work was done too."Mrs Soloman, Greenwich
