Windows from the best of hands

Freisinger products have evolved from specialist crafts, then introduced to the market and established through collaboration with medium-sized companies. Each product is therefore also optimised in terms of production technique.

Know-how has emerged through many years of collaboration and the constant improvement processes that resulted. The attention to detail, ambition for quality, achieving the perfect hard-crafted product and the passion to create innovation out of tradition are what characterize the special value of Freisinger products – not just on the technical side.

Sustainable values, which include individual and emotional qualities as well as technical perfection - thus guaranteeing customers comfort, security and impeccable service for the long term.
