What is External Wall Insulation?

External Wall Insulation explained

External wall insulation wraps around the outside of your home or business premises and stops valuable heat being lost through your walls.


It’s built up in layers, starting with insulation panels that are fastened to your walls with adhesive and mechanical fixings, and ending with a lightly-textured render that is waterproof and attractive.

As your choice of colour is permanent, you’ll never need to decorate again (although if you do want to change the colour in the future, the render can be painted).

The diagram below shows the build-up, and each element can be viewed in more detail here .
