We’re proud to announce that Shelter has signed a technology licensing agreement with WIEHAG, an Austria-based company and one of the world’s leading timber structure manufacturers. WIEHAG has contributed to landmark projects such as Ascent Tower in Milwaukee, USA, and Atlassian Central in Sydney, Australia.
Through this agreement, we will provide two of our core mass timber technologies: COOL WOOD, a self-extinguishing fireproof timber member, and the KES (Kimura Excellent Structure) System, our proprietary timber connection system using steel connectors. These technologies help make high-rise mass timber buildings safer and more viable.
By sharing advanced fireproof timber technologies developed in Japan, we aim to support the wider adoption of mass timber and contribute to a more sustainable urban future.
