Very good at dampening sound and insulating from heat. Just be aware it is unfaced, and unfaced is rather unpleasant to work with

Attic instalation 24inch
Would RecommendWell packaged. Solid. We have noticed an immediate difference in keeping room cooler when its hot out and warmer during recent cold snap. We needed the 24 inch to insulate a covered porch that we had converted into a sunroom and this was perfect for the job.
