Window location in structure
For the entire window structure to meet the energy saving requirements and ensure good comfort it is necessary to install the window in the warm part of the wall. This means that it should be installed as deep into the wall as possible, which has a number of advantages.
It creates good conditions for appropriate fixing and a well functioning joint. The risk of condensation is reduced due to a higher surface temperature. The joint between the frame profile and the wall shall be made with two step sealing. This means that it should consist of an outer rain barrier with an underlying air channel, a mineral wool insulation layer and an inner diffusion sealing joint.
Fixing principles
Windows must be fixed to a stable and suitable wall structure. The choice of fixing method depends on the wall type. The number and location of fixing points depends on the size of the window.
