Value retention: Regular maintenance and modernisation increase the value of your

value of your property and extend the life of your windows.

Reglazing

With Zöllner’s re-glazing, existing products can become “energy savers” without having to completely replace the windows.

– All Zöllner wood-aluminium windows from previous generations can be easily upgraded to special thermal insulation glazing.

– Additional installation of a sash overlap seal ensures greater tightness and better thermal insulation.

– Check and, if necessary, replace the existing centre and glass seals

– Checking the windows as a whole for leaks and adjusting the sash in the frame to ensure it is seated correctly.

Conversion of the fittings to security class RC2N

Get increased burglar resistance for your window system to protect your living space by replacing the existing window fittings with high-quality, certified security fittings to RC2N standard.
