💡 How do you properly install rock wool insulation for best noise reduction results?

Getting solid acoustic performance with mineral wool batts comes down to proper fitting and securing since these dense panels rely on full contact with your framing. - A handy move is dialing in your measurements so the sheets seat tight against the framing. - You really ought to run some hanging wire above the drop ceiling since the weight pulls fast without backing. - Pair these slabs with double layer gypsum to choke out stubborn gear rumble in practice spots. - Keep a shop vac nearby because cutting generates fine dust that coats your garage floor quick.✝️
