Looks like someone already corrected you on the drywall part but just for further clarification, drywall is literally used as a fireproofing material. In hot work rooms on commercial properties building codes actually call for 2 layers of drywall specifically for fire prevention. You can take an oxyacetylene torch to drywall and it won't do much more than smolder and smoke a bit. It is intensely fire resistant. A fire needs to be pretty damn big already to make it through the drywall to the wood frame of the building. Modern wood frame construction is pretty good as far as fireproofing goes. The big issue the US has are the houses built during the post WWII housing boom that use shit like masonite or wood paneling for wall coverings and then fill the walls with shit like tar paper and shredded rags for insulationbwhile also having shody wiring.

Drywall isn't wood, it's also called "sheet rock" for a reason. It's mostly gypsum and it does a pretty good job slowing the spread of fire.
