KELLER AG considers itself more than ever to be a specialist in individually planned window and door elements which, thanks to the unique wood-aluminium combination, combine an almost infinite variety of manufacturing options in terms of shape, colour, equipment and finishes with the best possible service for the building owner.
KELLER offers its wood-aluminium windows and doors in the opening variants side-hung, bottom-hung, turn / tilt and as tilt / slide systems.

Passive house certified

KELLER develops intelligent windows and doors. The high-quality thermally insulated wood-aluminium windows and doors from KELLER AG are ideally suited to passive house construction and meet the passive house energy standard for new buildings.
Our customer-oriented way of working is characterised by individual detailed planning and quality assurance. KELLER's expertise is also reflected in the very elaborate system maintenance and continuous product development. The premium customer offer is rounded off by thermal calculations, computer-controlled simulations and 3D visualisations.

The perfect mix
of materialsWood-aluminium windows combine the good thermal insulation of wood with the resistance to weathering of aluminium. Thanks to the exterior aluminium, preserving coatings are no longer necessary and the windows still look lovely even after decades of use.
All materials, surfaces, shapes and colours can be matched to your house in order to create an atmospherically unique ambience that will delight you.
We attach great importance to top quality, perfection and purposeful support to create your dream windows.
