No, the cladding did not “cause the building to go up like a matchstick.”
Self-evidently, the fire spread far too fast from a combination of factors:
- Air gap behind cladding, creating a chimney effect
- Lack of effective fire breaks
- No sprinklers
- Fire Brigade did not send tall appliance as a matter of course
The testing of different combinations of insulation and cladding is mostly a charade to divert attention from the four key failings (particularly #1, which is stupidly mandated by most BC departments).
