Lower your energy bills with external wall insulation
External wall insulation is a popular choice for homes with solid walls where a layer of insulation is added to the exterior of a house. It has huge energy-saving benefits by keeping your house warm and reducing energy bills.
With external wall insulation, you’re not only saving money, you’re also transforming the look of your property and adding value to your home.
Wondering how to tell if your home has solid walls or cavity walls? If it was built before the 1920s, it will likely have solid walls and could benefit from external wall insulation.
How does external wall insulation work?
There are several types of insulation products that can be attached to the outside of the property to insulate externally. These include expanded polystyrene (EPS), mineral wool, phenolic resin (K5) and woodfibre. EPS is the most popular option as it’s cost-effective and easy to install. An installer will always run through the best option for your home and its benefits.
After the exterior insulation material has been applied, the walls are normally finished in a weather-resistant, decorative render that comes in a variety of shades and finishes from pebbledash to a brick-effect design. Other available finishing options include composite cladding and brick slips. Whatever finish you choose, external wall insulation is designed to reduce your heating demand, prevent heat from escaping through the walls and overall improve your home’s thermal efficiency without taking away interior wall space.
