ift-Montageplaner (ift-Installation Tool)


The professional installation of windows will be described in the "Guideline for installation of windows and external pedestrian doors (Montageleitfaden)" in detail, and there are a lot of suitable sealing and installation systems whose fitness for use has been verified by tests performed according to the ift-Guidelines MO-01/1 „Wall connection of windows" and MO-02/1 „MO-01/1 „Wall connection of windows - Part 2“ .

However, the implementation to specific installation situations and wall connections is still extensive. This is the starting point of the ift-Installation Tool, that was designed by ift Rosenheim in cooperation with Company Würth as a first pilot project.
