- External Wall Insulation
External wall insulation is a method used to reduce heat loss in buildings with solid or poorly insulated external walls. Unlike cavity walls, which have a gap between two layers of brick or blockwork, solid walls have no such cavity and can easily allow heat to escape, making the building less energy-efficient. External wall insulation involves applying insulating material directly to the outside of the walls, which significantly enhances their thermal performance and helps to maintain a consistent indoor temperature.
