Wärmedämmverbundsystem

WärmedämmVerbundsystem, often abbreviated as WDVS, is a German term for External Thermal Insulation Composite Systems. These systems are widely used in building construction to improve the thermal insulation of exterior walls. A typical WDVS consists of an insulating material, such as expanded polystyrene (EPS) or mineral wool, which is adhered or mechanically fastened to the existing wall. This insulation layer is then covered with a reinforced base coat, into which a reinforcing mesh is embedded. Finally, a decorative render or plaster is applied as the outer finish. The primary purpose of a WDVS is to reduce heat loss from a building during winter and heat gain during summer, thereby improving energy efficiency and occupant comfort. By creating a continuous insulation layer on the exterior, WDVS effectively minimizes thermal bridges, which are areas where heat can escape more easily. Installation of a WDVS can lead to significant reductions in heating costs and a decrease in the building's carbon footprint. These systems are available in various thicknesses and with different types of finishes to suit aesthetic and performance requirements. Proper installation is crucial to ensure the long-term effectiveness and durability of the system.
