If your house was built before 1920, it’s likely that it was built with solid walls. Twice as much heat escapes from solid walls than cavity walls, so insulating solid walls can considerably cut your heating bills.You’ll also notice a fresh new look, as external insulation can enhance your home’s appearance. Whether you’re renovating or building new, it’s a smart step toward better living and energy efficiency.

Exterior wall Insulation
External wall insulation works by adding a protective layer to the outside of your home, helping to reduce heat loss and improve energy efficiency. It’s especially useful for solid wall properties that don’t have cavity walls. By wrapping the exterior in insulation, your home stays warmer in winter and cooler in summer.
The system typically involves several layers. First, an insulation board (usually made of materials like expanded polystyrene or mineral wool) is fixed to the external walls. Then a reinforcing mesh is applied over the board, followed by a base coat. Finally, a decorative render or finish gives your home a fresh new look while protecting the insulation beneath.
