External Wall Insulation

< Back to all products

Did you know?

Up to 35% of the heat lost from your home goes through the walls.

If your home was built before 1920, it probably won’t have cavity walls. External wall insulation (or solid wall insulation) is an alternative to cavity wall insulation which will prevent heat-loss, reduce carbon emissions and save you money. Similar to cavity wall insulation, it acts like a blanket around your house to keep heat in.

How does is work?

A layer of insulation material is fixed to the outside walls of your house. It is then covered with a special type of render and can be finished to your liking — smooth, textured, painted, tiled, panelled, pebble-dashed, or finished with brick slips.

What are the benefits?

External wall insulation generally has more advantages than internal wall insulation, and is less disruptive. It will improve the appearance and lifespan of your walls and can help prevent damp and condensation (any existing penetrating or rising damp will need to be dealt with first).

Can I get a grant?

If you are receiving certain benefits, then you may qualify for FREE external wall insulation through the GEARS program. Read more about GEARS here.

How much will I save?

For a typical 3 bedroom semi-detached house, you could save around £475 a year in heating bills, and 1.9 tonnes in CO2 emissions per year.
