External Wall Insulation

What Is External Wall Insulation?

External wall insulation involves fixing insulation boards to the outside of your home and covering them with a protective render or decorative finish. This creates a continuous thermal barrier around the building, preventing heat loss, protecting the structure from weather damage, and improving your home’s external look.

It’s one of the most effective ways to increase energy efficiency, particularly for older homes that don’t have cavity walls.

Benefits of External Wall Insulation

• Reduced Heat Loss – Keep warmth inside and reduce cold spots for a more comfortable home.

• Lower Energy Bills – Cut heating costs by improving thermal performance.

• Weather Protection – Shield your property from damp, wind, and rain damage.

• Improved Appearance – Refresh your home’s exterior with a clean, modern finish.

• Eco-Friendly Solution – Lower carbon emissions and boost your EPC rating.

• Increased Property Value – Enhance both the look and efficiency of your home.
