What is external wall insulation?

It’s a technique used to improve the energy efficiency, thermal comfort, and external appearance of buildings by adding insulation materials to their exterior walls.

This process is particularly beneficial for properties with solid walls or those without cavity walls, as they tend to have lower insulation levels and higher heat loss rates.

External wall insulation offers several benefits:

Improved energy efficiency

By reducing heat transfer through the walls, it can lower heating and cooling costs, making your home more energy-efficient and comfortable.

Condensation control

By increasing the wall’s temperature, it helps to minimize condensation and associated issues, such as dampness and mold growth.

Noise Reduction

The added insulation can also help to reduce external noise levels, improving the overall living environment.


External Wall Insulation can enhance the appearance of a building, giving it a modern look or preserving its original style.

EWI can be a significant investment upfront, although this is often offset by long-term energy savings and potential grants.

Installation disruption
The installation process may cause some inconvenience, as it takes place on the building’s exterior.

If the external finish or sealant is damaged, water may penetrate the insulation system, causing dampness and reducing the insulation’s effectiveness.

Structural issues
In rare cases, adding external wall insulation may exacerbate existing structural problems or create new ones if not properly assessed and addressed before installation.
