Typical EWI is generally applied to solid wall buildings i.e. no cavity within the brick wall construction. However EWI can also be applied to Cavity wall constructions to enhance thermal performance. There are a wide range of finishes available, the sysem pictured above shows Weber.therm XP. Other finishes include through colour silicone & acrylic, scratch render through colour finish, brick effect, brick slip & aggregate dash - all in a wide range of colours.

EWI systems that are available from our suppliers come with a British Board of Aggrement certificate and a 10 year warranty.

When installing EWI to building regulation requirements, the property energy rating typically increases from F to C/B on solid wall properties.


Roto Fix

The Insulation within an EWI system is often mechanically fixed with a cementitious adhesive. However, as with all industries, manufacturers are striving for improvements to their systems.

Roto Fix is a patented fastener solution that can create a cavity without the need of timber or metal battens. This can also alleviate problems occurring from an uneven background or to achieve Architectural features such as curves.
