Our Products


high-quality wood or.
wood-aluminium solutions

Quality, not quantity: For us, windows aren't mass-produced items. Rather, they are bespoke products that are individually planned and designed and lovingly made to measure. With outstanding insulating properties and top-quality security systems. Choice wood varieties such as meranti, larch or oak ensure a pleasant indoor ambience. And combinations of wood and aluminium on the outside reliably keep out the elements.



the front door.
a very personal 

Like few other elements, a house's front door connects people with the architecture. Relying on standard solutions here wouldn't do justice to either. That is why we only offer individually created, bespoke front doors.



made by hand.
shaped by experience.

For most people, these days Luxembourg definitely doesn't evoke images of traditional manual crafts. Yet there is one company that has steadfastly specialised in producing handcrafted quality: OST in Grevenmacher. For half a century, we habe been turning out products that meet the highest expectations in terms of aesthetics and functionality.
At first we only made windows. But we have meanwhile extended our portfolio to include front doors, mullion-transom façades and other products. Everything is fashioned by hand with the greatest possible care, skill and attention to detail.

We are proud, to have our statement in our name: OST manufacture.
