External Wall Insulation
What is External Wall Insulation?
​
External Wall Insulation, also referred to as EWI, is a system of components applied to the exterior of a property to insulate, protect and enhance its aesthetics. There is a wide range of materials, fixings and finishes helping us to ensure that the performance and aesthetics are perfect for our customer's needs.
​
Why should you use External Wall Insulation?
Insulates your property, significantly improving the thermal efficiency of a property
Reducing money spent by residents on heating bills
Reducing carbon emissions
Provides a new, improved look to properties in need of refurbishment
Pushes the dew point externally helping to prevent condensation
Highly durable finish
Eliminates cold bridges in property walls
Protects the structural fabric of the building from the elements
In the UK almost a third of all homes have been constructed with solid walls that cannot be insulated via cavity wall insulation.
​
Properties constructed in this way lose a significant proportion of all their heat through the walls unless they are insulated.
​
The effectiveness of all your investments from improved heating systems, new doors and windows and insulated lofts and floors are minimised. Therefore, insulating solid walls is essential if these properties are to be made thermally efficient.
