Rated 4.7 out of 5 by 32 reviewers.
Rated 5.0 out of 5.0 by No-nonsense underlayment We used this 3 in 1 underlayment to put down 1500 sq ft of laminate flooring. It was very easy to spread, cut around and tape. It was put on after leveling the floor, has provided a sound proof cushion for the12 mm laminate flooring. You can see it under the laminates in the picture below. We never hear any clicking noise. It is a quality product, with a low price. December 10, 2013
Rated 5.0 out of 5.0 by Great Product The underlayment rolled out easy and the taped ends to stick the new roll to was helpful so there was no shifting. October 1, 2014

Rated 5.0 out of 5.0 by Love how it warmed up floors Installed this product on top of 3/8" plywood and under bamboo flooring in a 140 sq ft room last year. Noticed last year that it immediately warmed up the floor when I was installing it, sitting on it. This year, really seeing a difference in ability to keep 1928 house warmer & dryer in January in Houston (humidity outside 60-99%). Room on northeast side of house was impossible to keep warm last year. Now? Toasty with a $40 oil-filled radiator and a 500 Watt radiant heater with outside temps at 37F. Humidity level pre floor install was routinely 70%+. Now? 60% inside humidity, if raining outside, 35-45% today, with outside temp 45F. The product is the most expensive of the line offered at HD, but spend the money, because you will get the savings back in lower heating and cooling costs, and, all around comfort level increase. All the windows in the house will have to be updated (single pane, 80+ years old), and found out the floor in the house didn't have a subfloor beneath it. Weighing my budget on doing 22 windows, or redoing 800 sq feet of floor myself, with a goal of better temp and humidity control, figured in this purchase. The square footage of the flooring letting in humidity through tongue and groove pine was much larger than the square footage of windows. I will probably use any left overs when I go camping, under the tent, or in the tent. It would seem to be the PERFECT product for an ultralite backpacker to carry as a ground cloth to minimize cold transfer. The rolls are pricey at $45 for a 4 x 25 foot section. I wouldn't want the roll to be any bigger, unless I was doing rooms larger than 12 feet wide, because handling the roll, while making cuts around door frames would be more difficult. February 3, 2015
Rated 5.0 out of 5.0 by good quality Not very easy to do with just one person, but was able to completely lay it and secure with duct tape as they recomended June 18, 2015
Rated 4.0 out of 5.0 by Underlayment for flooring project I was really impressed with the noise reduction after putting it down! June 16, 2015
Rated 5.0 out of 5.0 by Great Thermal Barrier Laminate Hardwood over a concrete slab and the floors stay warm. Also provides acoustic insulation as well as the floors sound like a premium hardwood with this installed. January 5, 2015
Rated 5.0 out of 5.0 by Underlayment for New Floors I find that it has insulated the floor before the new floors were put down. The room is warmer and not so much cold is coming through January 6, 2015
