What is external wall insulation?

Do you have cold solid exterior walls? You can insulate a solid wall by adding external wall insulation.
External wall insulation is the process of insulating your home by applying insulation to the external walls.
If your home was built before the 1930s, then you might have solid walls that need insulation. External wall insulation involves fixing a layer of insulation to the wall, then covering all the wall surfaces with a special type of render.
External wall insulation is the most cost-effective form of insulation for solid walls where there is no cavity between the walls that can be filled.
How does external wall insulation work?
With external wall insulation, you can enjoy great energy savings without having to reduce the floor area of your home.
Your external wall insulation will also help improve your home’s weatherproofing and sound resistance, and you’ll extend the lifespan of the brickwork while giving the property a makeover too.
There are a number of different materials that can be used for external wall insulation, so it’s important to choose one that is suitable for your home.
