External wall insulation (EWI systems) improve the thermal performance of a property while also updating its external appearance — but it only works properly when it’s detailed and installed correctly.

We install external insulation systems suited to the property, construction type and environment, helping improve energy efficiency and overall comfort. The process involves careful preparation of the existing structure, precise installation, and considered finishing to ensure the system performs as intended over time.

Particular attention is paid to junctions, openings and penetrations — the areas where performance is often lost if not handled properly. By getting these details right, we help maintain thermal continuity and reduce the risk of issues such as moisture ingress or cold bridging.

This work is often carried out alongside wider renovation or external improvement projects, allowing insulation, finishes and overall appearance to be planned together from the outset.
