External Wall Insulation (EWI)

Heat Loss is one of the major issues in properties pre 1940. With solid brick walls, there is no cavity that can be filled with insulation. This can cause up to 35% heat loss through the walls alone. To help counter act this, we can install insulation, be that internal or external. By doing either of these options below, you will be adding a number of benefits to your property.


When installing external wall insulation, we are proud to say we are a Weber Recognized Contractor. That means when we install a EWI system, it's done to a specification, supplied to us by weber. This means you know the system has been installed correctly.

The main External Wall Insulation system we use is Webertherm XM. This is a multi-Layer system, starting with the insulation it self. This is covered with a 6mm adhesive render coat with a mesh laid within. When dry, this can be finished with a silicone textured finish similar to thin coat rendering or a brick-effect.

There are 2 different types of insulation boards that can be installed.
