made in Luxembourg
For over 50 years, we have been manufacturing high-quality windows, doors and glass facades made of wood and wood-aluminum as a Luxembourg family business.
Whether renovation or new construction: energy requirements set the framework today. Our different product lines, therefore, cover all energy requirements – whether for low-energy houses, passive houses, or even beyond. However, we are not only ideally positioned for new buildings.
We also create custom-fit individual solutions when it comes to identifying and eliminating energy weaknesses in renovation projects or listed buildings.
