Ease of install is the main thing. We found that working with ROCKWOOL, we’re a much faster crew and a much cleaner crew. We don’t have nearly as much waste on the job because our cutoffs with mineral wool can be put up in the rim joist and add additional R-value rather than loading up the landfill.
