Thermal bridges are areas where for example more heat is lost through a switch in materials than in neighbouring structural elements. Thanks to the low thermal conductivity of wood the thermal bridge effect of wooden structural elements is very slight. Any thermal bridges that arise can be minimised with the help of simple constructional measures.
With customary wall and roof construction, supporting elements (wood parts) that are used regularly alternate with highly effective insulation materials. The factor that determines the influence of thermal bridges for wooden constructions is thus the proportion of construction timber in the structural elements.
