Insulation Boards for EWI

Insulation boards for External Wall Insulation (EWI) are specially designed panels used to enhance the thermal performance of buildings. Typically made from materials such as expanded polystyrene (EPS), extruded polystyrene (XPS), phenolic foam or mineral wool, these boards are fixed to the exterior walls of a property and then covered with a protective render or cladding. The primary purpose of insulation boards is to reduce heat loss, improve energy efficiency, and create a more comfortable indoor environment. They also help to minimise condensation and mould growth, contributing to the overall durability of the building. Available in various thicknesses and sizes, insulation boards are a popular choice for both new builds and retrofit projects, offering an effective solution for improving thermal insulation in residential and commercial properties.
