Thermal insulation

Thermal insulation is a layer of material or assembly of materials used in construction to reduce heat transfer between a building's interior and its surroundings. Its main purpose is to maintain an adequate indoor temperature - minimising heat loss in winter and limiting heat build-up in summer. Thermal insulation helps to increase the energy efficiency of a building, leading to lower heating and cooling costs and improved occupant comfort. Insulation materials are usually mineral wool, cellulose wool, polystyrene, polyurethane foam or insulation boards (e.g. STEICO facade boards).
