Thermal bridges

Thermal bridges are also colloquially called cold bridges. These “weak points” have a negative effect on the energy balance of a building, as heat is lost from the inside to the outside. In the area of windows, thermal bridges can occur at the building connection, in the sealing planes or in the area of the glazing.

The so-called dew point plays a decisive role in thermal bridges. If this temperature is undershot, the moisture in the room air begins to condense. In simple terms, this is known as condensation. In addition to the energy loss caused by thermal bridges, which should be avoided anyway, this is one of the main problems, as it can lead to component damage and mold growth.
