Working to help reduce the amount of energy you need to heat your home, investing in cavity wall insulation could return a £140 saving each year.
With an estimated 33% of a home’s heat lost through the walls, it’s essential to ensure your walls are correctly insulated.
To decide if cavity wall insulation is suitable for your home, it’s important to first work out what type of walls you have. In some cases you can tell by the pattern of the brickwork or the period of your property, but if you’re unsure you should always call a registered engineer.
In most homes built after 1920 it’s likely that cavity walls are present. This is where the external wall is made of two layers that have a small gap, or cavity, running between them.
Cavity wall insulation fills that gap, preventing heat from escaping and also working to reduce condensation and damp within the home.
To install cavity wall installation holes are drilled in the outside wall and the insulation material is blown in using specially designed equipment. Once the cavity is full the holes will b seealed.
