5mm Rubber Underlayment for Vinyl Flooring


  1. Mold and mildew resistant
  2. Dampens noises for a quieter environment
  3. Permanently resilient and will not become brittle with time
  4. Environmentally friendly, often consisting of tires that have been recycled, and often can be recycled again in the future


The most common type is rubber floor underlayment. Versatile and offering excellent sound dampening properties, it can be installed in areas where moisture may be an issue. It is resistant to mildew, making it a great choice for many applications.

It can be loose laid or adhered with an adhesive strip, glue, staples, or tape. We offer it in a variety of thicknesses and designs to suit the project.



It is available for athletic installations. Athletic floor underlayment plywood is designed to cushion the impact on the lower body joints versus doing repetitive motions on hard floorings. This provides cushion from hard surfaces, like concrete, and does not break down or compress. Dry lay this for a simple installation.

3/8 Cork Underlayment for Wood Floors


  1. Thermal insulation maintains warmth underfoot
  2. Durable material won't compress
  3. Moisture resistant for a healthier living environment
  4. Hypoallergenic
  5. Environmentally renewable resource

This is a popular choice for both commercial and residential buildings where dampening of sounds is a priority. It has a “spring back” property that allows the corks to return to their original shape, even after being compressed. Additionally, it is naturally filled with air pockets, making it an efficient thermal insulator.



Ours are found in sheets for easy handling and simplified installation. Think about our 3mm Roll for use when the assembly system is ceramic, natural stone, or wood with a suspended ceiling.



The AcoustiCork PR60 Wave Textured offers top quality high performance control of sounds. This is suitable for multifamily applications, and the unique wave texture minimizes direct contact with subfloors.

This innovative design results in a 25-point improvement in impact noise transmission. This is the highest documented performance for a model less than 1/4 inch thick x 4 feet wide.



For a thicker tile underlayment for tile floor installs, consider our 12mm product, available in a 2x3 foot sheet.

Rubber Cork Underlayment


  1. Aids in crack suppression as buildings settle
  2. Feels warmer on bare feet
  3. Yields a quieter space
  4. Expands and contracts naturally
  5. Resists mildew and mold for a healthier environment


This combines the properties of both rubberized materials and corks. This is most frequently favored due to its ability to perform suppression of cracks, as it can help to prevent cracking during settling of the structure. It carries thermal benefits, yielding a more comfortable space.

Please note that it should not be installed under linoleum due to the potential of staining the tile.

 If looking for maximum quality, then consider the AcoustiCork RC1000 10mm 15-Foot Roll. This combines renewable corks and recycled tires, making a model that provides the ultimate in sound control. It can be used with virtually any hard surface.

This is also available in a 5mm thickness to meet or exceed building code, developer requirements, or condominium association rules.

Soundproof Underlayment



Our SilentTread 1/2-Inch x 25 Foot Roll has three times the dampening weight of competitors' products.

This is made from recyclable tires and can yield points toward LEED Green Building Council Certification. The floor underlayments will not be crushed or degraded over time.



If working in an area where water is an issue, then consider the SilentTread XL with Vapor Barrier.

This offers the same exceptional noise protection as other SilentTreads, but it also includes vapor guards. This has a laminated polypropylene film that prevents damage due to transmission of vapors through a concrete subfloor or a waterproof wood subfloor. It's an excellent way to help maintain the investment.


We have a variety of models in our catalog that are suitable for the home project to the commercial application. While exploring options, please don't hesitate to give us a call. Our experts would be happy to help find the right product. They can also provide samples and detailed information on shipping.

FAQ Floor Underlayment Q&A


Do I need foam underlayment for laminates on plywood?
Where dampness is a problem, such as on the lower level of a home or above a crawl space, installing a vapors moisture barrier over plywood is a good idea. It is not necessary on the upper levels of the house. A thin foam pad as a floor underlayment is a nice solution, although other materials work well too.

What does wood floor underlayment do?
Here are the advantages of wood underlayment:
  1. Reduce sound vibrations and movement between floors
  2. Provide cushion to athletes
  3. Even out minor subflooring imperfections for a more stable feel underfoot
  4. Keep floorings feeling warmer by preventing cold from coming through
  5. Prevent water from permeating it (if purchased with vapor barriers)

Is a cork floor underlayment necessary for hardwood floors?
If there are concerns regarding dampness seeping through and reaching the hardwoods, the carpet padding, or the vinyl planks, such as with basements, then basement subfloor underlayment is a worthy investment. In areas with no worries about excess water, installing this is not a necessity.

What is the best plastic floor underlayment?
Plastics work nicely where firmness is required. Beyond plastics, all cork underlayments that we offer are acoustically tested with results acceptable to national standards. Rubberized and cork flooring underlayment improves the finished product and serves as a best underlayment for laminate flooring on concrete. Polyethylene foam floor underlayment has cushioning properties that are beneficial.

What is the difference between subfloors and floor underlayment?
Subfloors are made to provide support to the structure of the floorings, and they are installed in the majority of homes and buildings. Choosing an underlayment is ideal when installers have a specific function in mind, such as noise reduction or prevention of dampness from reaching the laminate and engineered wood when installing laminate flooring.
