Window renovation with simultaneous external insulation

This façade section faithfully illustrates a window renovation with simultaneous or possibly later façade insulation. This may have an effect on the window size.

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

New slat blinds instead of the old roller shutters

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

In order to create space for the slat package, the new windows were moved inwards in this example.

Optimal thermal insulation thanks to sophisticated technology

This window renovation was carried out with wooden aluminum windows. The roller shutters were replaced at the same time. Working hand in hand with other tradespeople is one of our strengths. Organized and coordinated by our specialists

Thanks to the perfect detailed solutions in the roller shutter box and the two-part weatherboard adapted to the inclination of the existing sill, optimum tightness is guaranteed.

Perfectly solved renovation details

Classic example of a 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 allows access to the roller shutter through the inspection opening and the closures can be made airtight.

 

Perfectly fitting 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 precisely adapted to the dimensions of the building so that cover strips are largely unnecessary 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.
