External Wall Insulation (EWI) helps reduce heat loss, improve comfort, and reduce energy bills, by applying insulation to the outer walls and then finishing with a protective render. It's particularly beneficial for homes with solid walls, as it prevents cold spots, minimises draughts, and helps keep your home warmer in winter and cooler in summer.
Other key benefits include:
- Enhancing the aesthetic appearance of your home with a smooth, modern finish to the exterior.
- Protecting the building from weather damage, including moisture and wind.
National Insulation supplies offer a range of high-performance insulation products:
