# Heat losses through windows

QuickField simulation example

Calculation of the heat insulation of the building walls is an important stage of the design process. Additional heat losses arise from the thermal conductive inclusions such as underfloor bridging, window slopes, balcony plates, brackets of the system of the insulation facing and the other essential elements of the facade.
It is necessary to calculate these losses for accurate determination of the overall thermal resistance value.

Problem Type
Plane-parallel problem of heat transfer.
