Quality
Keller Minimal Windows by AluK has been manufacturing in the north of Luxembourg since 1990 and in 1994 we were awarded the “Made in Luxembourg” label. All phases of the work, from development and planning via manufacture to assembly are performed in-house.
We use only the highest-quality aluminium profiles which have been extruded especially for our product lines and we work with trusted partners and suppliers to ensure that the products made in our factory are of absolutely the top quality. Every home conservatory is fully preassembled and tested at the factory before it is delivered to its future owner. New product series and components are exhaustively tested and optimised before they find their way to our customers.
Perfection in detail
Along with aesthetics, the perfection of our products is a central aim. We place immense value on sophisticated design but also on care and attention to detail. We use the highest quality materials, modern production processes, the long term experience and innovative ideas of our engineers and the craft skills of our employees.
