External wall insulation combines the benefits of improving the aesthetic appearance of a building whilst at the same time reducing energy costs. It insulates external walls to produce the appropriate U-value without condensation risk, and allows the fabric of the building to act as a heat store to increase thermal efficiency and prevent cold bridging and mould growth.

Historically it has been used primarily in the refurbishment of social housing, multi-storey blocks of flats and offices, schools, universities, museums, hospitals and health clubs. In more recent years however it has become widely popular for new build developments.

The new Building Regulations Standards (in particular Part L: Conservation of Fuel and Power) are putting increased pressure on designers to provide energy saving solutions within the new build package. External wall insulation and rendering can provide this saving, as well as offering other benefits such as extended building life, weather resistance and decoration.

The external wall insulation systems are applied to the exterior walls of existing or new buildings. The insulant is either mechanically or adhesive fixed direct to the substrate and followed by a render basecoat with a reinforcement mesh. A weatherproof decorative finish is then applied to complete the system.
