Cavity Wall Insulation

Insulating your property not only creates a warmer home, but gives you an improved energy rating and reduces the costs of your energy bills! And the best thing – it could be fully funded under the government scheme ECO, so you might not have to spend a penny to save money.

What is Cavity Wall Insulation?

If your house was built after the 1920s, it is likely to have cavity walls, whereas older houses are more likely to have solid walls. Cavity wall insulation fills the gap in between the walls and keeps the heat from escaping. The insulation is blown into the walls through drill holes on the external walls of the property by a machine. Once the insulation is in, we fill up the holes and if necessary paint over them.

What material do you use?

GHE use Provincial Seals CWI18 15/5257. It is a glass mineral wool fibre treated with a water repellent. It is durable, rot proof and stable to remain effective as an insulant for the life of the building. It also has a Class A1 Fire Classification, which is the best attainable.

It is BBA accredited and CIGA (Cavity Wall Insulation Guarantee) approved, meaning they will provide a 25 year independent guarantee when fitted by registered installers which GHE are!
