Unique renovation technology
Window renovation is a matter of experience.
Our window fitters, all of whom have years of experience, specialize in renovations. We place particular emphasis on treating our customers' property with care.
Thanks to our unique renovation technology, from window quality and old window removal to professional building connections, the professionals at Fenstersanierungs AG guarantee the highest possible quality.
Window renovation with simultaneous external insulation
This facade section illustrates a faithful reproduction of a window renovation with simultaneous or possibly later facade insulation. This may affect the window size.
In this example, the reveals and lintels were insulated by 40 mm and the existing stone bench by 20 mm.
Our specialists will be happy to advise you on the options available.
New slatted blinds instead of old roller shutters
Take advantage of the benefits of new slat blinds. Thanks to our proven renovation technology, it may be possible to install new slat blinds, depending on the situation.
In this example, the new windows were set inward to make room for the slat package.
Ask our construction professionals, we will be happy to advise you—even on complex solutions.
Optimal thermal insulation thanks to sophisticated technology
This window renovation was carried out with wood-aluminum windows. At the same time, the roller shutters were replaced. Working hand in hand with other tradespeople is one of our strengths. Organized and coordinated by our specialists.
Thanks to the perfect detail solutions in the roller shutter box and the two-part weather strip adapted to the slope of the existing bench, optimum tightness is guaranteed.
Perfectly solved renovation details
A classic example of window renovation with internal roller shutter box, window sill on brackets, and radiator niche.
Thanks to the use of notched special frames, the existing sill brackets do not need to be removed.
The installation of a special service cover groove strip ensures access to the roller shutter through the inspection opening and allows the ends to be made airtight.
Precision-fit window renovation without cover strips
Windows fitted precisely into the building structure, eliminating the need for unsightly cover strips.
The technicians at Fenstersanierungs AG measure the windows with millimeter precision. During production, the windows are adapted precisely to the building dimensions so that, as far as possible, no cover strips are necessary on the inside and light loss can be avoided during the renovation.
In addition, the connections to the building structure can be made in a structurally correct manner.
Conventional window renovation. Wall differences are concealed on the inside with cover strips.
Best possible product quality
We have selected the best possible window manufacturers for our customers. Whether in the areas of heat, sound, or burglary protection, in terms of workmanship or aesthetics:
"Only the best is good enough."
