Tall Mass Timber Fire Testing

Fire Test screenshot

Identically furnished, multistory, one-bedroom apartments constructed of exposed, partially exposed, and unexposed (protected) five-ply cross-laminated timber (CLT) passed a series of five rigorously monitored fire tests. The purpose of the tests was to provide data that helped inform recommendations the ICC Ad Hoc Committee on Tall Wood Buildings (TWB) proposed for the 2021 International Building Code.

Misinformation About Fire Safety is Dangerous

Fire is a danger for all buildings and construction sites – regardless of building material. Fires start in the contents and furnishings we bring into our homes, and occur in concrete, steel, masonry, and wood buildings alike. What is most important is building to code to ensure safe buildings for occupants and first responders.

The Construction Fire Safety Coalition is a collaborative, multi-stakeholder coalition that is dedicated to reducing the occurrence of fires in buildings under construction, alteration, or demolition. To achieve this goal, coalition partners will align on best practices and agree to promote awareness of the coalition and offer educational materials and opportunities to stakeholder organizations that value a fire safe construction site. Information on becoming a partner is available upon request by email at
