Dämmverbundsystem

A Dämmverbundsystem, often abbreviated as WDVS, is a composite thermal insulation system for building exteriors. It is primarily used for insulating the external walls of buildings to reduce heat loss and improve energy efficiency. The system consists of several layers that are applied directly to the facade.

The core component of a WDVS is the insulation material, typically rigid foam boards made of polystyrene (EPS) or mineral wool. These boards are affixed to the wall using adhesives, mechanical fasteners, or a combination of both. A reinforcing layer is then applied over the insulation boards. This layer usually consists of a base coat of cementitious mortar or synthetic resin mixed with a reinforcing mesh, typically fiberglass. This mesh provides structural integrity and prevents cracking.

The final layer is the decorative finish, which can be a render, plaster, or facade paint. This outer layer protects the underlying insulation and reinforcing layers from weather influences such as rain, UV radiation, and temperature fluctuations. It also provides the aesthetic appearance of the building's facade.

WDVS offers several advantages, including significant improvements in thermal insulation, leading to lower heating costs and increased living comfort. They can also help to prevent condensation and mold growth on interior walls. Furthermore, they can protect the underlying building structure from environmental damage. Installation requires specialized knowledge and adherence to manufacturer guidelines to ensure optimal performance and durability.
