What is External Wall Insulation?

A layer of insulating material (typically 60mm boards) is fitted to the outside walls and covered with a type of render or cladding. There are a variety of finishes to choose from, including: smooth, textured, tiled, painted or brick/stone effect.

  • Insulating material fixed to outside walls.
  • Render/cladding applied to make decorative finish.
  • Brick, stone or tiled finishes also available.
  • Adds a protective weatherproof layer.
  • Improves external appearance and property value.
  • Leads to large savings on heating bills.

External Wall Insulation provides a weatherproof layer that will protect your brickwork, increase sound resistance and help to prevent damp problems.

The insulation material is fitted to the outside of a property so it won't reduce the floor area and can be installed with minimal disruption. It will also renew the appearance of your walls, increase the value of the property and will result in large savings on heating bills.

Is my property suitable for External Wall Insulation?

Your property must meet the following criteria before External Wall Insulation can be installed:

  • Be constructed of solid brick, stone or concrete (not timber-frame).
  • Have walls that are structurally sound and not in need of repair.
  • Not be a listed building or in a conservation area/world heritage site.
  • Not have any signs of damp in the walls.
  • Have good access to the outer walls.
  • Not lead directly onto a pavement i.e. have no garden or drive.
  • Not have cavity walls that are already filled or can be filled.

You should also check with your local Council whether planning permission is required. This is unlikely to be granted if the property is a listed building or in a conservation area/world heritage site. If planning permission is not granted, Internal Wall Insulation should be considered.

If your property is brick-built, you need to be sure that it does not have cavity walls. If it was constructed before 1924 it is likely to have solid walls and will require External Wall Insulation. If there are any square brick-ends in the pattern as shown below then it will be solid.

Another good indication is to measure the thickness next to doors or windows as Solid Walls tend to be less than 10" thick, whereas Cavity Walls are normally more than 10".
