Great ProductReview by Frank G.
Ease of Installation
Used this underlayment on installations on a first floor engineered hardwood floor over a wood subfloor, and in finishing a basement under a laminate floor over concrete subfloor. Worked great for both applications. Very good noise suppression for the wood floor, and nice easy feel under the laminate while completely eliminating any echo from the flooring. Both were floating installations. Great value and could not be happier with the results. (Posted on 7/25/2017)
5 Stars!Review by Tyler E.
Ease of Installation
We purchased the Floor Muffler Ultraseal Underlayment Jumbo Roll and we are extremely satisfied. I wanted my flooring to look and feel like hardwoods but be scratch proof for my dogs. This underlayment paved the way. It is super quiet, makes the laminate feel like hardwoods, and best of all, it didn't break the bank. 5*! (Posted on 5/18/2017)
Very SatisfiedReview by Steven C.
Ease of Installation
Product was shipped quickly and arrived earlier than estimated. Package was secure and was undamaged upon arrival. Underlyment was easy to unroll, instructions were easy to follow and had no problems. Other reviews I read said there were issues with unfolding barrier but I had no issues and thought it was very easy to install.

After completion the underlyment provides proper stability and reduces noise. I'm very satisfied with my experience with the product and best laminates service.

Thanks best laminate!
