Why External Wall Insulation Matters
If your home has solid, stone or poorly insulated walls, external wall insulation is one of the most effective ways to improve its energy efficiency.
At Retrofit Design Ltd, we’ve completed hundreds of external wall insulation projects nationwide, helping homeowners reduce heat loss, cut heating costs and give their homes a modern, refreshed look.
With a proper external insulation system, your home stays warmer in winter, cooler in summer and far more comfortable all year round.
What Is External Wall Insulation?
External Wall Insulation (EWI) involves fixing rigid insulation boards to the outside of your home’s exterior walls, then applying a weatherproof render or decorative finish.
This creates a continuous, protective thermal layer around your property, reducing heat loss and enhancing your home’s appearance.
The process delivers:
- Improved energy efficiency
- Reduced heat loss
- A clean, modern exterior finish
