External wall insulation

External wall insulation

Solid walls let twice as much heat escape as cavity walls. External wall insulation reduces the loss of heat substantially and thus decreases the amount of fuel used to heat your home. It also protects the exterior of your home by filling cracks and gaps, weather proofing and increasing sound resistance.

Houses built before 1930 are typically of solid construction and could benefit from external wall insulation. Prior to any work beginning, your home will receive a full survey to ensure it is suitable for external wall insulation. Once viability is confirmed, external wall insulation will be fixed to the outside of your wall and then a decorative finish is rendered on top. Insulation can take up to two weeks to complete depending on the size of your home.
