Description - Our 6mm pre-cut rubber underlayment is about a millimeter thicker than our 5mm underlayment, but offers an increased amount of sound absorption comparatively. Our rubber underlayment is the perfect thickness for both commercial and residential flooring projects and provides all the benefits of any other rubber underlayment. You can install this over both concrete and wood and can be loose laid as well as adhered using glue, tape, nails or staples. This flooring underlayment also features an antimicrobial additive which aids in the inhibition of mold and mildew which are properties already associated with rubber. This underlayment also helps reduce the “hollow” or “pingy” sound that you hear with many laminate, hardwood, and engineered wood floors.
Material - Our 6mm pre-cut rubber underlayment is comprised of more than 85% recycled rubber.
Width - 4 feet wide.
Length - Our pre-cut rubber underlayment rolls come in 25’ and 50’ lengths.
Thickness - 6mm (Approx. 1/4”).
Weight - 1.00lb./sqft.
Origin - Made in the USA.
Recommended Uses - Our 6mm sound proofing underlayment offers a solid surface underneath your flooring surface, and is a popular choice for hard surfaces such as hardwoods and natural stone. 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 Composite 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? 
Can you give me an idea of the R-Value of the 6mm underlayment? I'm looking for an underlayment under carpet over a radiant floor.
Rob Lonning
Our underlayment is not tested specifically for R-Values, but the typical R-Value for rubber is 1.10.
What is the STC rating of this product.
Does this meet Field Impact Insulation Class (FIIC) 55 or higher and Airborne Noise Isolation Class (NIC) 55 or higher?
Richard Straus
We do not have results for these exact tests. Our 6mm Pre-Cut Rubber Underlayment has been testing for IIC and STC and has the following ratings: IIC 60 and STC 55.
Does the rubber underlayment act as a moisture barrier as well, or do I need to install a moisture barrier first?
The rubber underlay does not act as a moisture barrier. We recommend putting a moisture barrier down first.
Can this be used in walls for sound transmission?
Our 6mm Pre-Cut Rubber Underlayment can be used on walls to help dampen sound transmission from wall to wall. This rubber underlayment will not be as effective as say foam wall paneling or insulation, but it will give some sounds reduction.

I bought this rubber underlayment to put under a floating engineered hardwood floor. The underlayment is gypsum concrete. I wanted the best soundproofing I could get for my money because I'm in a 2nd floor condo. I have to admit that I was skeptical because the price was so much lower than competitors, but I had no problems with it. I ordered over the phone and customer service was great!! They said shipping could take 2 weeks, but it arrived in 1. It's actually 6.4mm, which is exactly 1/4″. It absorbs sound very well. The only cons are that the rolls are very heavy and its difficult to cut, but that's to be expected because it's rubber.

I was extremely happy with the product and company. The website made it easy to review rubber flooring options. My call to the company was answered immediately, and the representative helped me setup my order of rubber flooring and glue. The packages arrived ahead of schedule. I am an amateur home improvement guy and the install was simple. The glue worked great and the flooring is complete. (The off-gasing is a little strong, but I am airing out the room as much as possible.)
