Windows and doors

More modern than ever, we manufacture wood and wood/aluminium windows and doors for private housing, residential and commercial buildings, for public-sector customers and for cultural heritage as well. It has been a long time since windows, doors and front doors were only functional. They are design elements that form an integral part of the harmony of your living space and interior design. We are manufacturing according to the highest standards in a modern or historic look.

A good investment: thermal insulation and economic efficiency

As the topics of energy efficiency and passive house standard for energy-oriented refurbishment and new construction are becoming ever more crucial, we are able to give architects and builders clear evidence of the advantages of both the wood/aluminium HA Mira Passiv system and the HA Mira Therm 08 system. Those who insulate properly can save energy, and this applies in particular to windows and doors. Excellent air quality and a healthy pleasant indoor climate bring a good quality of life and a comfortable feeling. With the wood/aluminium HA Mira Passiv system and the HA Mira Therm 08 system, you would particularly benefit from their sealing system which fulfills all requirements thanks to their excellent noise and weather protection, and their outstanding performance in thermal insulation. That is a reason for joy, now and in the future, because you will never have to paint your wood/aluminium windows any more. Thanks to the high-value insulated glass equipped with triple glazing and an Ug-value up to 0.5 W/m²K, we are able to offer window elements of the highest standard. In addition, the insulation values are enhanced, owing to the so-called “warm edge” which is a thermal improved edging of the glasses.


Kleinhans attaches the greatest importance to the use of wood from the sustainable forest management. In this respect, the company uses especially local wood. For tropical timber from natural forests, the preservation of the nature for future generations stands at all first place. That is why we are able to process PEFC and FSC certified timber as well. They stem from sustainably managed forests and are subject to strict control by the Forest Stewardship Council (FSC). Pine and pruce are our standard wood, and in addition to these standard supplies we also use oak, larch and meranti in our program. We will be delighted to provide you with personal, individual advice. We are able to process all standard window forms within the range of the following profile system with an almost unlimited choice of colors. Outstanding characteristics, proven technology and years of experience speak for the Kleinhans high standard quality.
