Forna has brought in 12mm cork underlayment because of increased demand for thicker underlayments. These requests have come from frustrated condo or apartment owners whose HOA or condo associations will not work with a thinner product. 12mm cork underlayment is had been rare in the past but is becoming more and more mainstream. Too many apartment dwellers are removing the carpet because of health reasons, only to find their way blocked by their HOA. The demands put on solid or hard surface flooring puts the owner between a rock and a hard place.
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
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.
Old fashioned STC/IIC ratings are well documented to be heavily falsified – but no one at on the Board is listening. They can’t hear anything over the noise of thumping feet and or a bouncing bass. Noise complaints are the single greatest producer of written and verbal complaints that an HOA or Condo Board will face. And their idea of a fix is to ask for the moon – or more commonly a luxury condo insulation rating for a lower-than-middle class building. This is common and becoming more and more main-stream as consumers choose to move away from carpet or soft coverings.
In comes 12mm cork underlayment. It has been tested underneath Pergo laminate (considered an acoustic “zero” = 0 dB of insulation) and scored an incredibly impressive Delta IIC rating of 22.0 dB. That’s just for the underlay. Most floor+underlay combinations rate less than 14.0 dB, where the “good acoustic” floor/underlay combos score 14.0 dB or greater.
Forna has also brought in the highest possible density rating for their 12mm cork underlay (210kg/cubic meter). Compare this to the industry standard of 180kg/cubic meter. In the world of acoustics, density reigns. The denser the cork (or any material for that matter) the higher the acoustic rating. That makes Forna’s 12mm cork underlay doubly impressive.
