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.

This flooring underlayment is also mold and mildew resistant which is due to the fact that rubber does not hold water.

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.

Would the 5mm work in a wall as a sound barrier? I plan to sandwich it between two layers of sheetrock.
Our 5mm Pre-Cut Rubber Underlayment can be used as a wall sound barrier between sheetrock.
Can any of your rubber underlayment can be used with heating floors? (for example, the underlay would be directly on concrete floor in the basement, with electric heating mat over the underlay and laminate floor on top) Thank you!
All of our underlayments can be used with heated floors.
can this be used as underlayment for porcelain tiles.
Rubber underlayment is a popular choice for use underneath stone and tile floors.
Can this be used under foam tiles without applying adhesive? I want to use this in my hallway under some 5/8" foam tiles I purchased and over existing hardwood flooring.
We would not recommend using this directly over hardwood flooring. Please note that putting any flooring over hardwood can be damaging to the hardwood.
We live in a condo, and 2 years ago, new 5mm vinyl plank flooring was installed and glued down to the concrete gypsum floor. The flooring is in really good shape, but now the condo association wants a 5mm rubber underlay installed for noise suppression for the suite below us. Can we install your 5mm rubber underlay overtop of the existing plank flooring and install new floating locking laminate flooring over it? Or do we need to strip the 5mm vinyl planks off before installing your underlay?
You can install our 5mm Pre-Cut Rubber Underlayment over an existing vinyl floor.

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

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.

Except for the rolls being heavy (for me), it is a great product
