Description - Our 3mm pre-cut rubber underlayment is a millimeter thicker than our 2mm roll, but offers a greater amount of sound reduction comparatively. Rubber underlayments are very popular with hard surfaces because rubber is more rigid and provides the firmness necessary to resist compression from heavy objects and foot traffic. Our underlayment is also mold and mildew resistant due to the addition of an antimicrobial additive that inhibits the growth of both. Our flooring underlayment also doesn’t hold water, which allows for the installation of the underlayment without a vapor barrier. But if the flooring will be installed in an area where water may be present, then a vapor barrier would be required. Also, a vapor barrier may be needed per the manufacturer’s warranty. This soundproofing underlayment is also very popular with our Grid-Loc and Modular tiles because it is very thin and reduces the noise that can be made from them. So if you are looking for an underlayment that is affordable but at the same time gives you good sound absorption, then this is the product for you.
Material - Our 3mm pre-cut rubber underlayment is comprised of more than 85% recycled material.
Size - 4' x 50'
Thickness - 3mm (Approx. 1/8”).
Weight - 0.50lbs./sqft.
Recommended Uses - Our 3mm flooring underlayment is designed to be used in both commercial and residential applications. Rubber underlayment is the favorite to use under hard surfaces such as natural stone and hard woods, but it has also been successfully used under ceramic tile, laminate, engineered wood, real wood, marble, brick, pavers, parquet, carpet and tiles. It is NOT recommended for VCT (Vinyl Composition Tile), vinyl, and linoleum.

Rubber Underlayment

  • Why rubber underlayment?

Rubber underlayment offers superior sound resistance, is versatile and resilient. Comprised of recycled materials, this environmentally friendly product provides cushion underfoot as well as reducing sound transmission and impact sound such as footsteps. Amazingly, a 2mm thick rubber underlayment has similar testing numbers in sound resistance as compared to a 6mm thick cork underlayment.

Do I REALLY need underlay?

  • Yes, most definitely.

Underlayment is an amazing invention created by the flooring gods out of necessity. Underlay has an impressive list of benefits, including: adding warmth to your floors so your feet aren’t so cold on new tile flooring, adding comfort and a slight ‘give’ underneath wood or vinyl floors, reduced sound transmission (great for houses with noisy teenagers!), as well as reducing in room step noise. The image to the left is a very simplified example of using underlayment versus not using it, but as you can see the benefits greatly outweigh any reason not to.

Making your house a home

  • Products that work together

A favorite for use with hard plastic garage tiles, hardwood flooring and stone floor tiles. Rubber underlayment should never be used with vinyl flooring, VCT, or linoleum flooring as it could potentially stain these materials.


  • What does it mean?

Underlayment with a thickness of up to 5mm thick are great when it comes to residential or commercial use, with all flooring types. When you get to more than 5mm thick, these are really great for installations where you need to add thickness to match up with an adjoining/existing floor surface.

IIC / STC Ratings

  • What do they mean?

IIC stands for Impact Insulation Class, which refers to impact sounds such as shoes hitting the ground, dropping a cell phone, or other scenarios where something it dropped or impacts the floor. STC stands for Sound Transmission Class, which refers to any audible noise (not an impact) such as music playing aloud, a conversation, or a loud television, for example. With both of these ratings systems, the higher the number rating is for the underlayment, the better it will suppress sound, and the quieter a room will be. You may want to pay close attention to these ratings when shopping for underlayment if sound reduction is important to you.

Don't see what you're looking for? 
I want to use this rubber underlayment under a heated tile floor. won't this give when you walk on it and break the grout? shouldn't you glue this down so it doesn't move when installing tile? sounds like you can't mud over the rubber and then install the tiles on top, so what goes over the top of the underlayment to mud the heat cables on then the tile? what thickness should you use?
Rubber underlayment can be used underneath floor heating and we would recommend gluing it down in your scenario. The heating element can be installed directly to the rubber underlay, please check with the floor heating product guidelines for that product. 3.2mm thickness is suitable for this application, you may choose another thickness only if you need to add further height to the floor.
Is this the right underlayment for your sports tiles on concrete slab?
You can use our 3.2mm Pre-Cut Rubber Underlayment under sports tiles on a concrete slab. This rubber underlayment will provide you with ample shock absorbency helping to protect your joints while at play.

  Very happy
Installed in Garage under tiles
Hari R. from Bridgewater, NJ wrote...
I am very happy with the purchased of tiles as well as underlayment. I was pleasantly surprised by the low amount of noise being transmitted by the flooring. I put the underlayment first and then installed the floating tiles for my garage. Impressed with the shine and the performance (sound insulation). Whole process took about 8-10 hours (underlayment+Flooring) including the time for cutting the tiles. I did this for the first time and my skill level is minimal. overall I was happy that I was able to do this in 10 hrs. It was a satisfying purchase with not much wastage in material. I went with the material amount suggested by you and was left with about 20 sqft of flooring left which I might need just in case of any repair work. Friendly staff on time delivery made the experience better. I am attaching a few pics of my garage installation.

Self-installed in Pickup truck

I made two slide out drawers in the back of my pickup truck and I used this material as an underlayment under the frame of the drawers to keep it from sliding around in the truck. I also used it in the drawers and on the top so my tools don't slide around.

  Carpet Tile Underlayment
Self-installed in Loft

I did a lot of research before purchasing this underlayment. I was searching for an underlayment that would add a little cushion to a very large Interface carpet tile area rug. I purchased the 3.2 mm underlayment and it worked great. Its easy to work with and I connected the rolls with Gorilla tape as its stronger then duct tape. It made the carpet feel much more luxurious and helps with sound insulation. If I did it again I would use the 5.0 mm for even more cushion. Quality product, great price, easy to cut with a box cutter and the customer service was great. Thanks!
