External Wall Insulation (EWI)

Background

Insulating solid walls with External Wall Insulation (EWI) can help reduce some of the heat loss that occurs from this area of a property.

EWI is a fantastic system that can insulate newer and older properties including those that don't have post-1930s cavity walls. 

External wall insulation has a greater impact on the energy efficiency of a property than brand new A-rated double glazing or a new condensing gas boiler.

External wall insulation systems also provide a significate upgrade to the appearance of your property. We offer a huge range of different finishes, including different render granularity, almost limitless colours, brick slips and even pebble dash systems.

Why install external wall insulation?

Insulating your home could cut your heating costs considerably. Solid walls are notorious for letting through twice as much heat as cavity walls.
