Accessories for 6mm Pre-Cut Rubber Underlayment

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.

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.

    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.


    Our underlayment is not tested specifically for R-Values, but the typical R-Value for rubber is 1.10.

Good for hardwood underlayment
5/5 6mm Pre-Cut Rubber Underlayment
Kent from St. Louis, MO
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.

Great Product -BEST service!
5/5 6mm Pre-Cut Rubber Underlayment
Pat Blevins from Watsonville, California
We recently purchased 1400 sq ft of the 6 mm rubber underlayment to be installed below the carpet and pad of the beach condo above ours in hopes of being able to enjoy some peace and quiet in our condo for the first time in 8 years. The condo upstairs is rented out all year long and because of the two sets of bunk beds has kids running and jumping ALL the time. No fun for us, until this wonderful product did what they said it would do-- reflect vibration from foot "steps" up into the room instead of down into the timbers and our condo. I started to look into the purchase in Jan 2014. The customer service people worked with me throughout the long wait for the owner of the condo above ours to re carpet his condo. Nine months actually elapsed since I made the first contact and they held true to the discount they offered us for the nine months it took to order the product. Luis Montano gave me such excellent and consistent customer service and support far beyond any experience I've received from any other company. Luis is a true asset to Rubber Flooring, Inc. and anyone who is fortunate enough to work with Luis will not be disappointed. Our order had many atypical nuances and he worked with us individualizing the ordering process to accommodate our needs. We worried the product would not arrive in time to coordinate with the carpet installation, but there was no need to worry. The product arrived in just 8 days after ordering. The professional capet installer said the product was very easy to work with and in no way interfered with installing a thick carpet pad and upgraded carpet over the underlayment. The owner of the condo being carpeted was very pleased with the look and solid feel of walking on all three layers. We worried about the odor of the rubber in a rental unit, but there was no need to have worried. The odor quickly dissipated before the carpet installation was complete. I give this experience the highest rating of approval. Luis Montano and his superb customer service, the shipping and handling component and the product doing what it was designed to do, not to mention a very fair price, are the reasons I have rated this company, its product and our overall experience with 5 stars!
