Bamboo is a grass, not a timber, and that shows up here every March. Natural cane takes on water through cut ends and split skin, then freezes, and each cycle opens the split wider. Kept off the ground, sealed annually, and clear of roof runoff, it holds up. Treated as install-and-forget, it grays and cracks fast. Engineered board does not move that way.
Two very different products under one name: natural cane panels that screen for a handful of seasons, and engineered bamboo board that performs like composite for twenty years. Massachusetts winters are what separates them.
