Who Knew?! – Advantages of CLT over concrete for stairways in commercial buildings. In addition to the reasons most of mass timber advocates can list, apparently in the USA your building can also generate “WELL AP Credits” See the last bullet point.

CLT-based wall panels outperform traditional masonry shaft walls in several ways. Unlike poured concrete or masonry, CLT is:

• Lower Cost: CLT panel installation does not require as much labor nor the use of multiple tradespeople;
• Not Weather Dependent: CLT panels can be installed in all weather conditions, enabling more predictable scheduling and maintaining project timelines;
• Quicker to Install: Prefabricated panels can be installed in hours, by a single trade and require only a single inspection
• Sustainable: Sterling’s CLT panels are made from 100% domestically grown, regenerative timber dramatically reducing embodied carbon and supporting the health of US forests
• Generates WELL AP Credits. When left exposed in stairs, CLT generates WELL AP credits by making stairs biophilic which encourages people to take the stairs which leads to healthier lifestyles.
