The AL3 aluminium window was honoured with an iF quality seal at the ceremonious iF Design Award Night 2015 in the BMW Welt conference centre in Munich.

The design competition has been run by Industrie Forum Design e.V. for over 60 years, and is one of the most famous internationally. The iF DESIGN quality seal is a globally recognised trademark for exceptional design. The iF brand is internationally established as a symbol of outstanding design performance.

This year alone, almost 5,000 submissions have been made from 53 countries, and assessed by a jury of highly qualified experts. The sought-after iF quality seal in the Product / Building Technology category for the new AL3 aluminium window was accepted personally by executive director Marcel Hug.

The highly insulating AL3 aluminium window impressed the jury with its elegant, discreet design and its classic shape, and now has the right to bear the sought-after iF quality seal.
