Innovation and tradition go hand in hand at Schaden Fenstersanierung. The company emerged from the oldest carpentry workshop in Styria, which was founded in 1888. The first box-type windows were produced here 130 years ago. The production of new box-type windows is one of the company’s core competencies, along with window renovation. A 70-strong team at Schaden Fensterhandwerk ensures that up to 1,500 windows a year shine in new splendor. In the process, the windows are not only preserved, but also significantly improved using the latest methods and materials. The renovation of historical box-type windows, which we bring up to the sound and insulation values of today’s windows by means of a patented system, is also one of our specialties.
