Accessories for 6mm Eco-Cork Underlayment

Description - Our 6mm cork underlayment offers superior sound absorption while offering superior protection of your floor. This industry standard thickness outperforms foam underlayment and has the ability to suppress cracks in the floor due to fracturing in the sub floor. Cork also has the ability to ‘breathe’ which allows moisture to move through the floor which in turn helps to prevent mold and mildew. 6mm thick cork is equivalent to 2mm thick rubber, making it a great and inexpensive option for most of your flooring needs.
Material - Our 6mm flooring underlayment 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 truly 'green'.
Width - 4 feet wide roll.
Length - Available in 50’ and 98’ standard lengths.
Thickness - 6mm (~1/4”).
Weight - 0.27 lbs./sqft.
Recommended Uses - 6mm cork underlayment is a favorite of wood floors, but has been successfully used under ceramic tiles, hardwoods, and natural stone, vinyl, linoleum, luxury vinyl tiles and planks, engineered wood, vinyl composition tiles, cork flooring, and bamboo.

    I am wondering if I can use this product without putting anything on top? No furniture would be on top of it. Light walking only. I want to use in my craft room. It has wood floors in there now, and it's a cold room. I thought this might warm it up, and make it quieter, and look nice. Please let me know.


    This is a very unique application. You could try it or go with one of our soft foam flooring tiles (a common choice in craft rooms). The cork underlayment is not 'sealed' in any way, so if any damage was to occur it may cause flaking.
