What is external wall insulation?
External walls can be insulated by adding an insulating layer, either on the inside or the outside, to prevent heat from escaping through your walls while keeping the cold out. This will cost more than insulating a cavity wall but the savings on your heating bills will be bigger too.
Wondering what the difference is between solid wall and a cavity wall?
- Solid walls have no gap, so they can’t be filled with cavity wall insulation.
- Cavity walls are made of two layers with a gap or ‘cavity’ between them.
How can I tell if I have a solid wall?
Solid walls come in many different forms. Here are some common ways to tell if your home has solid walls:
- It was built before 1920
- The walls are less than 260mm thick
- The brickwork looks similar to that in the photo
You might need to have planning permission before installing solid wall insulation — check with your local council before starting.
Why is external wall insulation a good idea?
A cold wall will take heat away from anything around it. Solid wall insulation adds a thermally protective layer to the outside of your home. Here are some more reasons for insulation:
What our external wall insulation customers say
Before we were spending £25 to £30 per week on our gas and electricity during the winter and we had to have our heating on day and night. But now, the exterior wall insulation that has been installed keeps the cold out and the warmth in and we're spending much less.
Before the external wall insulation we used to have our thermostat on 25 degrees most of the winter but now we only have it on 15 degrees, any higher and the property gets too warm. Also we are definitely saving money on bills.
