What is External Wall Insulation?

External wall insulation is a layer of insulating material added to the outside of a building. It’s then covered with a special render or cladding to protect it from weather. EWI is really good for homes with solid walls, which are harder to insulate than cavity walls.

EWI has lots of benefits. It can really cut down your energy bills by keeping heat inside your home. It does this by creating a warm layer around your house that stops heat from escaping through the walls. EWI also helps keep your home cool in summer. Another cool thing about EWI is that it can make your home quieter by blocking out noise from outside.

One of the best things about EWI is that it can make your house look nicer. You can choose from lots of different finishes to make your house look how you want. Concrete rendering is a popular choice because it lasts a long time, can be used in many ways, and can give your house a modern look.

The Role of Concrete Rendering in Insulation

Concrete rendering is really important for EWI. It’s a mix of cement, sand, and other special materials that’s put on the outside of buildings. When used with EWI, concrete rendering does more than just make your house look nice. It helps the insulation work better too.

Concrete rendering creates a strong, waterproof layer over the insulation. This protects the insulation from water and weather, which helps it last longer and work better. It also helps the insulation work better by sealing any small gaps where heat could escape. You can choose different types of concrete rendering to make your house look smooth and modern or more textured and traditional.
