Description - Our 5mm pre-cut rubber underlayment offers superior sound insulation at the best price. 5mm rubber underlayment has been shown to outperform all leading forms of underlayment including 12mm cork and 12mm foam. Rubber is great to use in areas that are at and above grade and is a great underlayment in areas where water may be present. This flooring underlayment is also mold and mildew resistant which is due to the fact that rubber does not hold water. This sound proofing underlayment can also be installed directly over concrete or wood and does not have to be adhered to the system via adhesive. You can also float the underlayment in a free floating assembly.

    Would the 5mm work in a wall as a sound barrier? I plan to sandwich it between two layers of sheetrock.

Very happy with the product
5/5 5mm Pre-Cut Rubber Underlayment
Jennifer E. from Virginia Beach, VA
We have finally completed our project! We used the 5mm Underlayment Roll with 1/2 inch tiles over. We also cut pieces of the 1/4 inch mat roll to shock absorb while using weights. It looks great & feels great! We are very happy with the product.

Buffalo in the Attic!
4/5 5mm Pre-Cut Rubber Underlayment
Anonymous from Tennessee
We have a 1920's home. We asked the last tenant to move out of our attic apartment because, although she was a model tenant (she kept it pristine and paid her rent in a timely manner), she sounded like a buffalo pounding the floor above our heads. I couldn't bear it another year. We did our research and here is what we did. We took out the floor including the sub-floor. Then we installed everything new, with the rubber underlayment as one of the steps. We installed porcelain tile and 3/4" hardwood floor. Although I can hear an occasional sound if something is dropped, regular footstep sounds are non-existent. I am thrilled. The reason I gave 4 stars is that when I first called, the young man in customer service told me that we could install porcelain tile directly over the rubber underlayment rather than admit that he didn't know the answer. That is wrong. I would have much preferred that he said he didn't know.

Excellent Product
5/5 5mm Pre-Cut Rubber Underlayment
Anonymous from San Francisco Bay Area, CA
I am very pleased with the product. I was worried about the smell of the recycled tires in the underlayment. However, I was surprised that the product did not smell at all. It is really a good quality product that you can feel good about purchasing.

Used in Multiplex for Sound Reduction
5/5 5mm Pre-Cut Rubber Underlayment
Matt from Sarnia, ON
I just completed installation of this product under LVT and 12mL laminate with marked results. This was installed on the second floor of my multiplex and the tenants below recorded that all footfall noise was eliminated to the point that only hammering was heard. The floor is not insulated and did not have a dropped ceiling below so I am very happy with the result. I paired this product with acoustical caulking for best results. 5mm rubber cut very easy with a sharp box-cutter knife. Recommeded after extensive research and was happy with delivery time and the packaged product arrived with ample packaging for protection. Only thing is this stuff is HEAVY but great for adding density to your floor. Will purchase again for myself and friends. Matt

stable underlayment
5/5 5mm Pre-Cut Rubber Underlayment
Scott from Atlanta
I used this as an underlayment for my home theater. We used 18"carpet tiles on top and it worked perfectly. This product is a good sound dampener and served our purpose well. Rubber does a ground job of Isolating the bass frequencies on the bottom end and eliminating some of the reverberation. Next time i would probably go with the thicker version, as this is only a 1/4" pad, but it still worked well, and will never wear out like foam.

The right stuff
5/5 5mm Pre-Cut Rubber Underlayment
Anonymous from Seattle WA
We remodeled a second floor condominium unit which included floating 1/2" engineered hardwood floors over Gypcrete. We needed an underlayment that would pass muster with our condo board and downstairs neighbors. Rubber Flooring's 5mm pre-cut underlayment fit the bill. Our contractor installed the underlayment and hardwood and even he remarked at the solid feel and "real" sound of the flooring over the 5mm. It's only been down for a few weeks but we're extremely happy with the product. Now if only Rubber Flooring would have included a couple of burly types to help us get the rolls up to our second floor unit...
