Window renovation with simultaneous external insulation

This section of the façade is a true-to-the-original illustration of a window renovation with simultaneous or possibly later façade insulation. This may have an effect on the size of the windows.

In this example, reveals and lintel were insulated by 40mm and the existing stone sill by 20mm.
Our specialists will be happy to advise you on what other options are available.

New slat blinds instead of the old roller shutters

Take advantage of new slat blinds. Thanks to our proven renovation technology, it may be possible to install new slat blinds, depending on the situation.

Ask our construction professionals, we will be happy to advise you - even on complex solutions.

Optimal thermal insulation thanks to well thought-out technology

This window renovation was carried out with wooden alu windows. At the same time, the roller shutters were replaced. Working hand in hand with other craftsmen is one of our strengths. Organized and coordinated by our specialists.

Thanks to the perfect detail solutions in the roller shutter box as well as the two-part weatherboard adapted to the inclination of the existing bench, optimal tightness is guaranteed.

Perfectly solved renovation details

Classic example of window renovation with interior roller shutter box, window ledge on brackets and radiator niche.
Thanks to the use of notched special frames, the existing ledge brackets do not need to be removed.

By installing a special service cover groove, access to the shutter through the inspection opening remains granted and the closures can be made airtight.

Precisely fitting window renovation without cover strips

The window fits exactly into the building structure, eliminating the need for unsightly cover strips.

The technicians of Fenstersanierungs AG measure the windows with millimeter precision. In production, the windows are precisely adapted to the building dimensions, so that no cover strips are necessary on the inside and loss of light due to the renovation can be avoided.

In addition, the connections to the building structure can be executed correctly in terms of building physics.
