Laminated wood basically doesn't combust, so the fire hazard is comparable to most modern construction materials. Also, the way it's processed makes it extremely structurally sound.
- baybal2 6y agoExcuse me, but you were succesfully made to swallow the coolaid. No construction technique out there can make wood a safe construction material, no way, and no how. The wood still burns no matter how much fire retardant you soak in it, and it will inevitable rot, warp, and slip off fasteners. The vodoo cult of "wooden skyscrapers" is bizarre, and the way they slip past building regulations is even more. In BC, the wood lobby effectively managed to undo a fire safety testing for building materials, and rewrite a big part of fire code to make wooden skyscrapers possible.

- q_andrew 6y agoIn many situations, you are right. For instance, the five-over-ones being built in basically every city in the US exist because of a regulation loophole for building wooden structures (that constructing a fireproof barrier between two wooden structures allows you to build large, multi-story apartments with it). They are infamous for burning down during construction because they don't have sprinkler systems yet: https://www.bloomberg.com/news/features/2019-02-13/why-america-s-new-apartment-buildings-all-look-the-same https://www.bloomberg.com/news/features/2019-02-13/why-ameri... Cross-laminated timber has a "char layer" that keeps the other layers from burning through, and is even known for withstanding higher temperatures than steel: https://www.greenspec.co.uk/building-design/crosslam-timber-fire-resistance-and-rating/ https://www.greenspec.co.uk/building-design/crosslam-timber-...
