WHAT IT IS
Insulation and render, working together.
External wall insulation, or EWI, fixes a layer of insulation to the outside of your walls and then covers it with a protective, decorative render. It's the most effective way to insulate a solid wall property without losing any space inside.
​
For homes that lose heat through their walls, especially older solid wall properties common across the East Midlands, it makes a real difference to comfort and running costs, while giving the exterior a complete refresh at the same time.
01
Lower energy bills
02
A warmer, comfier home
​Keep more heat inside and cut what you spend keeping the house warm through winter.
​Fewer cold spots and draughts, with walls that hold their warmth far better.
03
A transformed exterior
04
Protects the building
​Tired or dated walls finished in clean, modern render in a colour of your choice.
​A weatherproof outer layer shields the structure from rain, damp and the elements.
WHY HOMEOWNERS CHOOSE EWI
The benefits go further than a fresh look.
