Why should I use solid wall insulation for my home?

Solid wall installation normally takes between 2-4 weeks and can be done with very little disruption because no interior work is needed.

  • Save energy

Solid wall insulation stops heat escaping from your home and keep you toasty while using less energy.

  • Lower your bills

You'll be able to heat your home for less money.

  • Improve your EPC rating

Your EPC rating (Energy Performance Certificate) shows how much your building costs to heat and light and how you can make it more energy efficient. Insulation makes a huge difference to your EPC rating.

How does solid wall external insulation work?​

External solid wall insulation is like wrapping your home in a blanket. There are a number of methods, but in the most popular, rigid insulation boards are fixed to your outside walls and then covered with a weatherproof coating. You then choose a finish, from a range of options (modern render, pebble-dash, brick-work), so you can change the look of your home at the same time as making it more comfortable and energy efficient.

Is my home suitable for solid wall insulation?

You need to check what kind of walls your home has before you consider solid wall insulation. If your house was built before the 1920s, it probably has solid walls constructed of a single brick or stone layer. It's easy to check whether you have solid or cavity walls. Just take a look at an external wall, window or door in your home and measure the thickness of the wall. If the brick is less than 240mm, then it is very likely to be solid wall.

Things to consider:

  • You won't need solid wall insulation if you have cavity walls.
  • If you're in a listed building or a conservation area, you should check if you'll need planning permission before get wall insulation.

How will solid wall insulation benefit my house?

Wish you could add more curb appeal to your home or make sure less outside noise gets in? Solid wall insulation not only means you use less energy and save on your bills but it has other great benefits too.

It can transform the look of your home – you'll be able to choose the finish of your walls from modern render, pebble-dash and brick-work. External wall insulation also improves weatherproofing and enhances sound resistance.

It's worth remembering that if your home is a listed building, within a conservation area, or is subject to other forms of planning constraints, then you may need planning permission.
