Very nice quality

This was great for the price. The only con is that the rolls are rolled in the wrong direction. They should be rolled inside out so that when you go to roll it out on the floor it rolls easily & you don;t have to turn it for underneath. But other than that it’s great stuff.

by TheViper - Home Depot Review

Easy to use

Used it under Cali Vinyl over 1700sq ft. Worked perfect.

Great value

We used it under first floor hardwood for sound dampening, and on basement concrete for sound and moisture control.
