"What is External Wall Insulation?"
A simple system that makes your home warmer, cheaper to heat, and more efficient.
External Wall Insulation (EWI)
It is a system that adds a new insulated layer to the outside of your home. This keeps heat inside, reduces energy bills, and refreshes the look of your property.
Why External Wall Insulation Matters
-
Stops heat escaping through your walls
-
Makes your home warmer all year round
-
Cuts energy bills noticeably
-
Reduces damp and condensation
-
Adds a fresh new look to the outside of your home
-
Increases your property value
External wall insulation is one of the most effective ways to improve comfort and efficiency in older homes with solid walls.
Who Is EWI Best For?
EWI is ideal for:
-
Homes built before 1930
-
Solid wall or non-cavity properties
-
Homes suffering from damp or cold walls
-
Park homes
-
Homes with high heating bills
-
Anyone wanting a warmer, quieter home
-
Anyone wanting a full exterior makeover
⭐ Warm Coat Tip!
“Think of EWI like putting a warm winter coat on your home — it keeps the heat in, the cold out, and makes everything feel more comfortable.”
How External Wall Insulation Works
External Wall Insulation adds a high-performance insulation layer to the outside of your property. This “thermal jacket” stops heat escaping through the walls and prevents cold from entering. The insulated boards are fixed to the exterior, reinforced with a strong mesh system, and finished with a protective render that seals your home against the weather.
Why It Works
-
Creates a continuous thermal layer with no gaps
-
Stops heat bridging through cold walls
-
Keeps internal temperatures stable year-round
-
Cuts heating costs by improving energy efficiency
-
Reduces the risk of damp, mould, and condensation
-
