Future oriented from the start

For generations our family-owned company, founded in 1919, has focussed on innovation. Because at the end of the day, we want you to feel comfortable with our windows! Therefore, we produce our high-quality products at our own factory in Speyer, Germany.

To ensure that you will be satisfied with our windows for many years to come, we combine cutting-edge technology with specifically developed patents. Durability, comfort, safety, light-related design and a highly-efficient energy balance are values which are important to us. And that’s how we always stay one window ahead.
