Comfortable living
Wood is nature at its most pure. Wooden windows convey warmth and comfort. They guarantee a natural and cozy living. Wood-aluminum windows offer all of these advantages because when seen from inside your home, they do not differ from classic wooden windows.
Durable and stable in value.
STEMESEDER wood-aluminum systems significantly increase the service life of your windows and make your property more stable in value.
Admittedly: A wood-aluminum window with wood-aluminum systems from Stemeseder is also a piece of personal luxury.
Extremely easy care.
Wood is a natural product and can be adversely affected by the sun, wind, and weather. Wooden windows, therefore, need a lot of care and have to be painted on a regular basis. This is where the modern material aluminum comes into play:
The exterior wood-aluminum system from Stemeseder almost completely eliminates the need for maintenance. The externally fitted STEMESEDER wood-aluminium system means that painting your windows is no longer necessary!
The premium aluminum systems from STEMESEDER come supplied with the beneficial GS Premium® surface. The GS Premium color tones are distinguished by this highly weather resistant surface and provide a sense of long-term elegance.
If the building is situated in a coastal area with a high airborne salt content or near roads that are salted heavily in the winter, we recommend our specialist »Seaside Protect« surface treatment.
