Expanded polystyrene EPS insulation board is a high-performing thermal insulation at the centre of our external wall insulation systems. It significantly upgrades the thermal properties of a building, improving U-values, and
reducing the risk of water penetration and condensation. EPS boards are compatible with timber, masonry and system-built properties, as well as tile hanging and a wide range of rendering systems.Although external insulation is an expensive insulation solution, it can also resolve other issues, such as rain penetration, poor airtightness and frost damage, provided the product used is NSAI Agrément certified
