Accessories for 3mm Eco-Cork Underlayment

Description - Our 3mm cork underlayment is a very easy and inexpensive way to upgrade the underlayment under your new and existing floor. Cork underlayment offers a higher level of sound reduction versus most standard foam underlayments and is also a great way to match the level of existing floors in other rooms. Cork also is mold and mildew resistant and will expand and contract with your floor. Our 3mm cork underlayment is the perfect underlayment to use under floating floors.
Material - This flooring is made from cork, which is harvested bark off of the cork tree. The bark of the tree grows back for over 200 years and can be stripped every 9 years, making this product a truly renewable product.
Width - 4 feet wide rolls.
Length - Available in 50’ lengths.
Thickness - 3mm. (.118”).
Weight - 0.23lbs./sqft.
Origin - Made in the USA
Recommended Uses - 3mm cork underlayment is a favorite of wood floors, but has been successfully used under ceramic tiles, hardwoods, natural stone, vinyl, linoleum, luxury vinyl tiles and planks, engineered wood, vinyl composite tiles, cork flooring, bamboo, and laminate.

Customer Questions & Answers

    does your cork or other floors require an adhesive or any additional products. I'm looking at the cork and the sound proofing (foil looking one)?


    In most installations the cork underlayment needs to be adhered with a urethane adhesive and a vapor barrier would need to be included. Our Sound Blocker Underlayment can be installed without the need for adhesive to the subfloor but you will need to remember to tape the seams with moisture resistant tape. Always follow installation instructions for any underlayment.
