  • Details
  • Installation Info
Description - Our 6mm cork underlayment Overstock 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. Overstock rolls are in great condition, available at a huge discount and are priced to sell. These rolls cannot be returned.
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 - 50’ long.
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.
