External wall insulation is a way of wrapping your home in a protective, insulating layer on the outside of the walls. Think of it like putting a warm, weatherproof coat around your house. It helps keep heat inside during winter and keeps your home cooler during summer.

By insulating the outside walls, it reduces heat escaping through brick or blockwork, which can help lower energy bills and make rooms feel warmer and more comfortable. It can also help reduce draughts and cold spots inside the home.

Another benefit is protection. The outer finish helps shield your home from rain, wind, and changing weather, which can help prevent damp problems and keep the structure in better condition over time.
