Cork Underlayment
Cork underlayment is a natural choice for commercial, industrial and residential use or for wherever resilience is important. Cork is a natural acoustic insulation material that is resilient to heavy usage. The cellular structure of this naturally harvested and renewable material has made it the most well-known and efficient insulator for acoustics, heat and mechanical vibration. Our natural cork underlayment helps insulate sounds.
This environmentally friendly and durable performer is a natural for underlays. Cork underlayment does its duty under dance floors, in gyms, offices, hospitals and homes. Even if you don’t want a certain floor to have the look of cork, you still have the feel of cork.
