Insulation Cork for Concrete Slab Floors

Cork Underlayment available at Warm Your Floor is 1/4″ thick (actually 6mm or .236″) and is manufactured by Amorim Industrial Solutions, the world’s leading manufacturer in every cork product category.

Amorim Industrial Solutions has specially engineered the state of the art cork insulation AcoustiCORK R60, which provides thermal efficiency to most types of floors. AcoustiCORK R60 is particularly useful under floor heating systems as it increases efficiency and reduces energy consumption, saving you money on operating costs.

Unlike most of its synthetic alternatives, AcoustiCORK R60 insulating underlayment has the ability to keep its acoustic and thermal insulation performance over many years. The physical structure of our cork, with nearly 200 million completely sealed air filled cells per cubic inch, makes it a very effective insulating material. This same physical structure also provides R60 with the ability to be repeatedly compressed, yet recover nearly 100% of its original shape and size.

With an R-Value of 3.1 per inch, the cork acts as a “thermal Break” and slows the heat transfer into a concrete slab sub floor when placed on top of the slab.

The floor heating elements are installed on top of the cork, and secured with tape or glue.

Cork underlayment also functions as a crack suppression membrane. Acousticork R60 is the economic and effective solution for stress crack prevention under ceramic tiles and hardwood floors. Quality cork underlayment sheets, like our product from the industry leader Amorim, have been tested extensively for use under tile installations.

Acousticork R60 is often used as a sound insulator in multi-story condominium buildings, too.

Amorim’s Acousticork R60 cannot be compared with most other cork products on the market. Our Cork is manufactured using a special process which provides the cork with unique features. Millions of square feet of AcoustiCORK^TM have been successfully installed under a wide variety of finished flooring materials in projects throughout the world.

This is NOT like bulletin board cork – this is an engineered cork product made specifically for the Tile Industry. The high compression ratio of our cork prevents cracking of tile and grout.
