External Wall Insulation (EWI)

Enhance thermal performance and transform your property’s exterior aesthetics.

What We Do

Stop Heat Loss

For buildings with solid walls, up to 45% of heat escapes through the external fabric. Our EWI systems wrap your property in a thermal blanket of high-grade insulation (EPS or Mineral Wool), which is then finished with a professional render system.

Why Use External wall Insulation

The Long-Term Value of Thermal Upgrading

Installing an EWI system is one of the most effective ways to add tangible value to your property while significantly reducing operational costs. 

  • Lower Energy Bills: Maintain consistent internal temperatures year-round by drastically reducing the rate of heat loss through external walls.

  • Improved EPC Rating: Directly increase your property’s market value and efficiency, making it more attractive to future buyers or tenants.

  • Enhanced Internal Comfort: Eliminate the cold spots and draughts that lead to uncomfortable living conditions and the formation of interstitial condensation.

The Process

Protecting the Fabric of Your Building

External Wall Insulation does more than just trap heat; it acts as a protective shield for the building’s structural fabric. By moving the “dew point” (the point where moisture condenses) from the inside of the wall to the outside of the insulation, EWI prevents the damp and rot issues that often plague older solid-wall properties. This process effectively wraps the building in a breathable, weather-tight skin, ensuring that the original brickwork or stonework remains dry and preserved for the lifetime of the system.
