 ====== Thermal bridge calculation ======
-[[basics:building_physics_-_basics:thermal_bridges:thermal_bridge_definition|Thermal bridges]] are an important instrument for identifying in more detail the heat losses from the building envelope. In highly efficient buildings such as Passive Houses, the influence of these losses has to be minimised. In ideal cases this is referred to as [[basics:building_physics_-_basics:what_defines_thermal_bridge_free_design|thermal bridge free connections or thermal bridge free design]]. Besides the heat losses, surface temperatures can also be determined with the aid of heat flow simulations, which allow conclusions to be drawn regarding thermal comfort, moisture development and the risk of mould growth.

+====  Installation thermal bridges ====
+Windows are essential for the energy demand of a building. If not properly installed, it results in high thermal bridges, reducing the overall performance of the building's insulation and leading to unnecessary heat loss. [[basics:building_physics_-_basics:thermal_bridges:tbcalculation:Thermal bridges of transparent components | Read more]]
