PERFECTION IN DETAIL

made-to-measure and a perfect fit

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. A KELLER product excels in every respect and is an absolutely premium product for those who are satisfied only with the very best.

A perfect fit

The ultra-precise manufacture and finish of KELLER AG is shown for example in the Prestige eaves profile, where optimum fitting to the complex projections immediately jumps out. The same applies for the mitres of the window profiles and joining strips.

Particularly when using different materials such as aluminium, glass and wood, measurements are precise to a millimetre in order to guarantee one hundred percent sealing and functionality, even after many years.

This high precision in the manufacturing allows us to produce the KELLER minimal windows® frameless sliding window system. No other window has such minute production tolerances, which require the precision of a watchmaker.

 

 

Outstanding functionality

A premium conservatory or window from KELLER is not just a visual highlight. We place immense value on optimum ease of use, functionality and quality. Everything needs to be simple, convenient and long-lasting. One example is the sliding window in a  KELLER minimal windows® sliding window system, which can often weigh several hundred kilograms. These open and close with ease (by motor if preferred) as you would expect from a premium product.

Innovative design

For a long time, conservatories were considered as unsuitable for everyday use – being too hot in the summer and too cold in the winter. KELLER has made a huge contribution to transforming this image and its conservatories are fully-functioning rooms for use all year round with designs that are still stunning after many years. The first ORANGERIE Elegance® design by KELLER AG is one of the milestones in the development of the modern home conservatory. The combination of glass side elements and a flat roof structure with glass dome has opened up completely new design perspectives which have served to inspire the competition. However, the perfection and quality of a KELLER Orangerie® remains unequalled.

Pratical Design

With the development of its minimal windows® system, KELLER has clearly demonstrated how to bring visual and functional design into perfect alignment. And the development of the KELLER GLASSHOUSE® only goes to show that we are always thinking a step ahead. Here, the KELLER minimal windows® design sliding windows are combined with the special flat roof construction. The result is a slimline and aesthetically pleasing living space expansion which blends as brilliantly with contemporary architecture as with traditional buildings.

A further innovation is the KELLER minimal windows® highline. It is a floor-to-ceiling glass façade with minimalist post profiles and completely invisible frame profiles.
