  • Cavity walls are made of two layers with a gap or ‘cavity’ between them.

What types of solid wall insulation are available

installing external wall insulation

What is external wall insulation?

External wall insulation is usually defined as a layer of insulation that's fixed to an existing external wall. 
This layer is finished either with a coat of render or with an alternative cladding to protect it from the elements.

For a typical home, external wall insulation starts from £11,100

What is internal wall insulation?

Internal wall insulation is used to insulate solid wall properties by fitting insulation to the inside walls of your home, creating a thermal barrier between the inside of your home and the outdoors, dramatically reducing heat loss. 

For a typical home, internal wall insulation starts from £6,875

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 solid 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 or inside 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.

Mrs W, Kingston

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.
