Rubber Underlayment is a rubber floor mat that assists in the elimination of noise problems relating to floors and ceilings.  It is an excellent approach for decoupling floors and/or ceilings in commercial and residential applications to help isolate and reduce both impact and structure-borne noise.  The rubber material provides a resilient layer within the flooring assembly for reducing vibration noise. 

Available in 3 thickness options: 2, 5 and 8 mm.  Rubber Underlayment is 48" wide and comes in roll form, 50' or 25' per roll.  Product can be easily cut with a utility knife or heavy-duty scissors to allow for exact coverage around obstructions.

Rubber Floor Underlayment can be used in new or retrofit construction.  It can be installed directly under any hard flooring elements such as engineered wood, laminate, stone, tile or vinyl. [When installing Tile directly over Rubber Undelayment only use the 2 mm thickness, anything thicker than that may cause shifting under the tiles. If you install plywood/OSB over the rubber underlayment and then the tile you can use any thickness including the 8mm].

How To Order:

When figuring how much underlayment is needed, add an additional 5-10% to the area of the room to allow for wastage while installing.  Choose from our three thickness options of 2, 5 and 8 mm.  Product is 48" wide and is available in roll form, 50' long for 2 and 5 mm thicknesses and 25' long for 8 mm thickness. We carry the 3, 6, 10 and 12 mm thicknesses too. Please call our office for pricing.

General Installation Instructions:

Rubber Floor Underlayment can be installed directly under hard surface flooring such as engineered wood, laminate, stone, tile or vinyl.

Finished flooring installation guidelines for all flooring types:

1. Follow the manufacturer's installation instructions.  Use their recommended materials.

2. Engineered Wood or Laminate is best if floated-don't glue.

3. Leave a 1/4" around the wall perimeter of the Rubber Floor Underlayment.

4. Tile, grout or laminate should be installed in contact with any wall.

5. Do not use mechanical fasteners through the Rubber Floor Underlayment as this will negate the acoustical performance of the system.


If cement backer board is required, glue it to the Rubber Underlayment with the recommended adhesive or mortar.


Top Rubber Floor Underlayment with a thin layer of adhesive.  Use a moisture cure urethane with a 1/32" trowel or adhesive recommended by flooring manufacturer.  Test to determine if the vinyl flooring/Rubber Underlayment assembly is able to resist indentation by heavy appliances, furniture etc.


Seal Rubber Underlayment perimeter with a non-hardening acoustical caulk.  Install baseboard on wall, but do not allow it to contact the finished floor, as this will reduce the acoustical performance of the Rubber Underlayment.

Customers Questions and Answers

1) Meghna C: Hello - My downstairs neighbor complains about my children running upstairs. They will not float their ceiling. Our floor/ceiling assembly is plywood subfloors with wooden joists. I don't think there's any insulation between floors. We have already put down thick rugs and felt pads, but they continue to complain. We can't remove our floors. Do you think an additional layer of some kind of impact noise reducing underlay might help? We would need to put it on top of our finished hardwood floors, then the pads, then the rugs on top. If so, which product would you recommend? Many Thanks.

Hi Meghna, I would suggest the Premium Carpet Underlayment with at least half inch of foam. We have gotten good feedback from our customers. Thank You,

2) David I: If I would be installing on to concrete floor, would I need to add a moisture control layer down before I installed the rubber underlayment? Also, what is the general STC rating for the 2mm rubber underlayment? David

Trademark Soundproofing Reply: Hi David, Rubber underlayments are mostly tested for impact reduction IIC Ratings. The 2 mm underlayment has tests of IIC 49 and STC 51 approx. However keep in mind these tests usually include other sound control mechanisims as well. Usually including resilient channel on the ceiling below and gypsum concrete on the floor. So unless you want to follow the exact floor/ceiling design put forth in the tests you will not achieve similar results..

3) Jackson: Hey guys, I have a duplex built in the 40's with wood joists between the two and I'm sure there isn't any insulation between the two. On the upper unit, there are hardwood floors. Couple of options here. 1) On the upper unit, rip out the old hardwood floors and put down the 8mm rubber underlayment. I'm not sure where I saw this but then lay plywood on the underlayment and then another layer perpendicular and then the flooring on top of that. I would like to install new hardwood. Or go all out and... 2) Same as #1 but before putting down the underlayment, cutting out some sections of the subfloor so I could insert some insulation between the joists. So my questions... 1) Do either or both sound like a good idea to control the noise between the two units? 2) I know you are not supposed to attached/screw anything through the underlayment into the subfloor but can you use short screws to attach the two layers of plywood together? 3) what thickness plywood would you suggest? 4) Am I missing anything or do you have another suggestion? I like your site because you have the thickest underlayment I have seen so far (8mm) and it seems the thicker the better in these cases. Thanks in advance!

Hi Jackson. The 2nd option is better. It may be easier to drill some holes in the floor between the bays and blow in cellulose insulation. You can screw the 2 upper layers together and if your budget allows, put some Green Glue damping compound between the 2 layers. We actually have 10 and 12 mm rubber underlayment as well. Thank you.
