Fensterinform Energy

Our broad expertise and experience underpin our window calculations as well as our window statics, window insulation, window sealing and therefore the future development of windows, too.


  • We provide calculations as a basis for window certification or to guarantee specific building requirements, e.g. concerning the window material.

  • We apply for the “Q-Signet” (quality mark) on behalf of the window manufacturing firms, for fire protection certification, for Minergie or Minergie-P and we make the necessary calculations and drawings.

  • We assess software solutions and advise our customers on the preparation of all the production processes in the window industry. Window production à la carte.
