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. Take advantage of our cavity insulation grants and contact us now.
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.
The savings
Around a third of all the heat lost in an un-insulated home is lost through the walls. If you have cavity walls, using cavity wall insulation will make a great difference. This is one of the best energy saving tips along with loft insulation to cut your heating bill.
How the savings add up
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. Do we cover home insulation grants in your area? Check out our areas covered.
