Works so well for underlayment for your laminate floor installation. So much better than the thin foam normally sold for this purpose. It eliminates the hollow floor sound. Easier to install, unfold and go. My husband has installed thousands of feet of laminate and his opinion is, "best underlayment I've used for customers that doesn't cost an arm and a leg"
This is much easier than the roll that keeps rolling up while laying down. It lays flat and the notches fit together easily. We sealed ours with tape. Easily cuts with a blade to fit where you need it. This product was a time saver for us.
