tigerwoodKhorns Posted January 18, 2019 Share Posted January 18, 2019 I am adding insulation to my attic to bring it up to R60. I want to add additional fiberglass bats above the existing insulation, but add mineral wool under and near the HVAC units to quiet them down. Anyone have experience with mineral wool? The Johns Manville is much cheaper than the Rockwool at the big box stores. How about a source for this stuff at a cheaper price/ Quote Link to comment Share on other sites More sharing options...
