About

External wall insulation boards are a type of insulation material that is applied to the exterior walls of a building. These boards are made from a variety of materials such as polystyrene, polyurethane, or mineral wool, and can be applied using different methods, such as adhesive or mechanical fixings. The purpose of these boards is to improve the thermal insulation of a building by reducing heat loss through the walls. This can help to lower energy costs and improve the overall energy efficiency of the building. The insulation boards may also improve the air tightness and prevent condensation inside the walls. They can also be used to improve the aesthetics of the building by providing a smooth finish to the walls and can be covered by various finishes such as plaster, brick, or wood cladding.
