Warum es für Werkstoffe bedeutsam ist
Wood dominates low-rise residential construction wherever it grows, because it is strong enough for the spans involved, light enough to be carried by two people and cuttable with hand tools on site. The demand is cyclical and interest-rate sensitive, and sawmill capacity cannot be added inside one cycle - which is the whole explanation for how violently lumber prices move.
