Nothing works better at reducing noise and sound transmissions between floors than cork. Now you can have our Acoustic Underlay – cork underlayment in a fabulous 12mm (1/2”) thick sheet.

Control the acoustic ambience of your home with our cork underlay. Cork is derived from the single most sustainable wood materials found in nature.

Each and every tree is left standing and able to provide future harvests.

Synthetic Foam

Wood, Laminate, carpet and ceramic floors absorb out body heat, thus the floors have a colder feel. Classic synthetic foams do not provide thermal insulation.

Forna cork underlayment placed under the floors reflect heat of our body, thus offering a more comfortable feel and protecting the natural warmth of your feet.

Our 12mm cork underlayment is the thickest sheet design. Comprised to provide the best when it comes to acoustic underlayment, we present it in a natural board pre-cut sheet format. Sturdy and rigid, you can work stress-free knowing these sheets will not break apart easily. 12mm sheets come in a 2ft x 3ft (24” x 36”) size and are packed 15 sheets per box. This will allow for a coverage of a 90 sq feet area. We use only 100% agglomerated cork bound together by a water-based adhesive or binders during the manufacturing process. As with the rest of our cork based product line, we are proud to state that our acoustic underlayment is toxin free and recyclable. Compare that to spray foam or fiberglass and you’ve got a better material for a cleaner earth.

Need help reducing airborne and impact noise. Cork offers a higher level of sound reduction versus most standard foam underlayment. Unlike synthetic foams, cork is a material that is by the very nature of its honeycomb like structure, which is composed of millions of air tight cells, a natural inhibitor resistant to the transfer of heat or sound. 12mm of cork can reduce noise up to 22 decibels, according you a little bit of peace and quiet. Acoustic cork underlayment can also be successfully used under wood, ceramic tiles, hardwoods, natural stone, vinyl, linoleum, luxury vinyl tiles and planks, engineered wood, vinyl composite tiles, cork flooring, laminate and bamboo.

Our underlayment is formaldehyde free and will act as a thermal barrier so a colder subfloor such as concrete will not leech thru to chill a room. With cork underlayment you’ll also get relief when it comes to heating and cooling bills as well. Cork helps to hold the ambient temperature in a room for longer periods, so you’ll cut back on running heaters and fans.

Imbued with some pretty fantastic natural properties, cork has demonstrated what beneficial qualities to can bring. Add our cork underlayment to your home and witness this for yourself.
