Window and Door Suites

We are here to make things easier, better and faster. View our range of suites.


Inline window systems

You’ve probably already noticed there’s something different about the way Stärke AMBIANCE™ windows and doors feel. 

We’ve set ourselves a higher standard for performance on almost every measure possible. The difference may be unseen but it’s all around us – creating positive changes in the atmosphere and how it makes your place feel. We make the things you cannot see better – silence, energy, warmth, air quality.
