External Wall Insulation
Home / Services Details
- A powerful upgrade for older homes with solid walls
FREE EXTERNAL WALL INSULATION
If your home was built before the 1930s, it probably has solid external walls that are prone to significant heat loss. Unlike cavity walls, solid walls don’t have an insulating gap, so heat escapes easily, making your home colder and your heating bills higher.
External Wall Insulation (EWI) is one of the most effective ways to improve the energy efficiency of these older properties. By attaching an insulating layer to the outside of your home and covering it with a durable, weather-resistant render, you can keep more heat inside, reduce your energy bills, and give your home a fresh new look.
External wall insulation not only reduces heat loss but also helps protect your home from damp and cold spots. The insulation layer acts as a thermal barrier, keeping your home warmer in the winter and cooler in summer, providing year-round comfort.
Key Benefits
- Lower energy bills
- Improved sound resistance
- Protecting against weather damage
- Boosted property value
What is External Wall Insulation?
External wall insulation involves fixing high-performance insulating boards to the outside of your home, then applying a protective render or cladding over the top.
The process typically involves:
- Preparing your external walls by cleaning and repairing any damaged areas
- Attaching insulation boards securely with fixings and adhesive
- Applying a reinforcing base coat and mesh for strength
- Finishing with a weatherproof, decorative render that can be customised to your preferred colour and texture
This external layer improves your home’s thermal efficiency while also giving it an attractive, modern exterior.
How Does It work?
External wall insulation is a proven way to improve the energy efficiency of solid-walled or poorly insulated homes. The process involves fixing a layer of insulating material, such as rigid insulation boards, to the outside of your property’s walls. This is then covered with a protective, decorative render or cladding to seal and weatherproof the surface.
By wrapping your home in a thermal blanket, external wall insulation reduces heat loss through the walls, keeping your home warmer in winter and cooler in summer. It also helps prevent damp and condensation, improves soundproofing, and can give your property a fresh, modern look.
The result is lower energy bills, improved comfort, and a reduced carbon footprint, without losing any interior space.
Why External Wall Insulation?
Switching to external wall insulation is a powerful way to improve your home’s energy efficiency and comfort. By adding a layer of insulation to the outside of your walls, you significantly reduce heat loss and protect your home from damp and cold spots. This method not only helps lower your heating bills but also enhances the appearance of your property with a fresh, modern finish.
