A fair point - but several factors, focusing largely on roof design, were highlighted in the article. Taken as a whole, it makes the case that concrete is not a strict requirement.
That's all I'm trying to say.
Being in the same category of a rating system does not mean it truly is as fire resistant as concrete. In Europe it would most likely not be classified as A1:
> An A1-Rated material is defined as a material that does not contribute to fire at any stage, including a fully developed fire.
The rating from the US is a bit more vague on the class A wood:
> Class A is the most desirable category for fire-rated plywood as it indicates a flame spread index of 25 or less.
"or less" isn't zero.
