Think globally, act locally
OPTIWIN is an international network of medium-sized window construction companies and wooden house builders. The partners develop, produce and distribute energy-efficient and visually attractive windows, doors and facades.

OPTIWIN combines the competence and individuality of the craftsmanship with sophisticated engineering skills. All window, door and facade systems are internationally tested, follow a classic design and can be customized according to customer requirements. A proof of their high quality is the prestigious Passivhaus Component Award, which was awarded the OPTWIN window systems 2014 and 2015 in a row.

Benefit from the comprehensive experience
The product development benefits from the extensive network experience: each partner brings in what they can best: a long-term experience from the renovation in the urban context, a certain manufacturing know-how or a deep understanding of the window construction on the coast in moist, salty Surroundings. In a professionally structured development process, a strong result is achieved, which optimally bundles the abilities of the companies.

Customers profit twice: from a broad-based network and from the regional proximity of the individual companies and their affiliation with the respective building culture.
