Curious if anyone’s tried adding an extra insulation layer underneath to help with both sound and thermal movement?
Extra insulation does help with noise, especially with lighter synthetics. I’ve seen folks use a high-density foam board underlayment—cuts down rain noise a lot. As for brittleness, it can help a bit, but if the material’s prone to curling from temp swings, insulation only goes so far. Fastener placement and making sure the deck’s flat are still huge factors.
