3 in 1 UNDERLAYMENT Laminate Foam 3mm 200 Sq.Ft. Floor

The rolls are not continuous, so one roll you order will have 3 or so pieces that you have to tape together end to end. The way the Mylar is attached onto the bottom is not consistent, sometimes there is a inch and one half to tape to the next row, other times there is none sticking out. Also this stuff is LOUD under small sections of flooring that don't press down on it much (like a hallway). It does not have an adhesive to join two pieces, so you have to go buy tape to use it. The Mylar backing makes lots of crinkling noises, under a large surface area it works fine though from a noise perspective. I just put it in, so I don't know if the noise will lessen over time, but currently it is annoying especially since they really claim to have noise REDUCING features. All in all I was disappointed in this product, but it was cheap so it does have that going for it.

For the price you can't beat it! But it's very spongey with thinner laminate hardwood flooring. It does what it suppose to do. Easy install.
