How does it work?

External solid wall insulation is like wrapping your home in a blanket. With the most popular method rigid insulation boards are fixed to the 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 energy efficient.

This extra layer of protection could help make your home more comfortable and save money on your heating bills.

No interior work is carried out, so installing this type of insulation can be done with very little disruption to you. 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.

Does my home have solid walls?

If your home was built before the 1920s, it probably has solid walls constructed of a single brick or stone layer. So to help it retain heat better, your home needs to be insulated, either from the inside or the outside.

To check whether your home has solid or cavity walls, simply measure the width of your wall. Look at an external wall, window or door in your home and if the brick is less than 240mm, then it is very likely to be solid wall.

Benefits at a glance:

  • Improves weatherproofing and enhances sound resistance
  • No reduction to floor area of rooms
  • Installation normally takes between 2-4 weeks, depending on the size of your home and prevailing weather conditions

For homes that are not suitable for external insulation, internal solid wall insulation could be a suitable option.
