Windows in aluminium: Windows with thermally insulating properties

Matched to your design idea and the stipulated protection standards, we plan and manufacture aluminium windows for residential, industrial and office buildings. Depending on the thermal insulation requirements, insulated or non-insulated window profile systems are used. Profile solutions from Bühlmann provide a great deal of design flexibility regarding aesthetics and styling.
