Treated lumber is a thing, and in my experience it’s harder to light than carbon fiber and resin.

My garage almost burned down once because I didn’t notice sparks from my angle grinder were pooling on a CF/R panel, and it set off a couple other things (paper towel bar, shop towel, solvent residue close to the towel) while I ran to the extinguisher.

This “article” is just an ad, and shouldn’t exist without actual journalism going on, but let’s not pretend wood can’t be fire resistant.
