Early this year forest fire fighters in Alberta were complaining that new houses have so much plastic in them that they were combusting and consumed in like 5 minutes making saving them impossible and slowing the fire’s spread harder.
I can believe it; in the UK our fire regs have become rather stringent due to the Grenfell fire, though those changes are mostly on flats/buildings more then 3(?) storeis etc.
The PVC external cladding can melt from a mid to large sized bonfire 10-15 foot away. We can’t use it to clad houses above the 2nd floor, though there are exceptions if your replacing existing cladding. So if you want to add a former to your loft you have to use tiles now.
Though there’s this interesting product called magply which is roughly as strong as ply, but is made from magnesium oxide and silicate. It’s considered incombustible so you can clad with it, then render it.
I wonder if we’ll start seeing different materials used in areas prone to forest fires
In the US houses are held together by thoughts and prayers.
Pine with a light dusting of steel & cardboard.
Plastic on exterior walls, paper and chalk on interior walls, and tar and gravel on the roof.

I’m having a hard time finding the quote. I found this explaining houses burn faster now than before because of plastic https://www.cbc.ca/news/canada/windsor/modern-homes-burn-8-times-faster-than-50-years-ago-1.1700063
Considering the ridiculous heat of those forest fires 5 minutes is believable
