To demonstrate mass timber’s fire resistance, engineers put the wood elements in gas-fired chambers and monitor their integrity. Other tests set fire to mock-ups of mass timber buildings and record the results.
These tests have gradually convinced regulators and customers that mass timber can resist burning long enough to be fire safe. That’s partly because a layer of char tends to form early on the outside of the timber, insulating the interior from much of the fire’s heat.
I live in a country where single family homes are built with wood. Everyone seems to trust their life to that. I don’t know why it would be different in an apartment.
Because these are literal sky scrapers. Fire on a wood structure is a recipe for catastrophic failure. A fire in a large structure could have similar effects to those large high rise condos that collapsed in Florida from poor maintenance.
This is very likely dangerous deregulation of the fire code to cut costs being “green washed” as a new thing that needs a hell of a lot more scrutiny. Building large structures with wood WAS a thing in the past, it was outlawed because it’s EXTREMELY dangerous when one of those structures ignites.
They’re only getting away with it because these are composite timbers which have been “tested” to be safer. I’m very skeptical that those tests are comprehensive, at least to the point where I would feel comfortable spending a significant portion of my life in one of these buildings.
