This is what Europeans never understand, because they have no native Douglas Fir over there. The mutation that lets them grow so fast isn't found in any of Europe's native species (which are mostly hardwoods anyways): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5592940 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5592940 > and treated it for flame resistance better. I don't. Almost all wood treatments off-gas toxic chemicals. The floor of my wellhouse is treated lumber and I don't care to spend much time in there. It's great for making decks though. Downside is that the treatments corrode screws and nails, so you have to use epoxy-coated fasteners but even those don't last more than a decade or two. Flame resistance is what sheetrock is for.
