External Wall Insulation

Add an insulated layer on top of your outside walls to keep out the cold and transform the look of your property.

What is external wall insulation?

Cavity wall insulation is unsuitable for pre-1920s, solid-walled homes. One great alternative suited to these properties is external wall insulation, where we apply a layer of insulating material to the home’s exterior walls, covered over with render or cladding. This job isn’t without its challenges, so proper forethought and care must be taken beforehand.

How does external wall insulation work?

External wall insulation typically involves fitting an insulated layer over your exterior walls, finished with either a coat of render or a layer of weather-proof cladding. Unlike internal wall insulation, adding insulation to external walls causes no disruption inside the property, nor does it affect the interior floor space – and the additional exterior layer helps cut down on outdoor maintenance as well. However, such a project is likely to require planning permission as it affects the facade of the building, and consideration must be given to windows and doors which may be adversely affected by a change in wall thickness.
