Quality

 KELLER 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.

KELLER ORANGERIE

The KELLER ORANGERIE Elegance® is a real masterpiece of home conservatory extension and pays homage to the classic, English Victorian originals of days gone by. High-quality slimline aluminium insulating profiles with optimum triple glazing in insulating glass make the KELLER ORANGERIE Elegance® an exclusive living space extension in summer and in winter.

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.

Energy efficiency

The home conservatories from the KELLER GLASSHOUSE® and ORANGERIE Elegance® series are so outstandingly well-conceived and insulated that they fulfil and indeed fall below the low-energy standard for windows with insulation values.

The path to your project
