External Wall Insulation

Wrap your home in comfort

External wall insulation (EWI) involves fixing an insulating layer to the outside of your home and finishing it with a protective render. This upgrade improves your home’s thermal performance by reducing heat loss through the walls, helping you save on energy bills while keeping your home warmer during. In addition to boosting comfort and lowering running costs, EWI enhances your home’s appearance, protects the structure from weather damage and increases its overall value

WHY CHOOSE US

Here's what sets us apart:

  • Lower energy bills

    EWI dramatically reduces the amount of heat escaping through your walls. By improving your home’s thermal efficiency, you can cut heating costs by up to 35%. Over time, these savings can more than pay back the investment in insulation.

  • Protects your home

    EWI adds a protective outer layer to your walls, shielding them from rain, wind, and fluctuating temperatures. This helps prevent issues like dampness, condensation, and structural wear, extending the lifespan of your home’s walls.

  • No loss of internal space

    Unlike internal insulation methods, which can reduce the usable area inside your home, EWI is installed externally. This means you gain all the energy and comfort benefits without losing any valuable living space.

  • Fresh new look

    External wall insulation gives you the opportunity to completely transform the appearance of your home. Choose from a variety of finishes, colours, and textures to achieve the style you want

  • Better soundproofing

    As well as thermal benefits, EWI adds an extra acoustic barrier around your home. This helps reduce outside noise from traffic, neighbours, or busy streets, creating a quieter, more peaceful indoor environment.
