Acoustic and Thermal Cork

Acoustic Cork

Sound absorption is the ability of a material to absorb sound waves. Cork can be used to absorb sound in specific environments reducing noise levels in such places as halls, auditoriums, concert halls, schools, restaurants, hotel rooms, apartment blocks, board rooms and private cinemas. The correct cork should be used depending on the frequencies and reverberations of the noise.

Acoustic cork has been recognised in the building industry as one of the most effective sound control materials. Cork’s amazing thermal and acoustic insulation qualities are due to its unique cellular structure ,which consists of approx. 40 million air filled cells per cubic centimetre. The entrapped air serves as a very effective noise barrier. Acoustic cork
should be used in buildings where it is necessary to reduce noise transmission from floor to floor or from room to room.

There are two areas where sound has to be controlled. The impact sound transmission (moving furniture, hammering, walking on wooden or stone floors) and the airborne noise transmission (music, loud conversation, street traffic). Both of these sound transmissions can be measured. ASTM and ISO acoustical testing methods are used as the criteria to determine acceptable sound transmission standards.

Acoustic cork in 6mm thickness exceeds most sound deadening requirements. Acoustic cork is available in many different thicknesses depending on the IIC and STC requirements.

Thermal Cork

Thermal Insulation – Cork provides natural thermal insulation and a high capacity to retain thermal energy. Cork insulates walls as it does not transfer heat or cold. It saves money on heating or cooling costs. By using thermal cork as an underlay for underfloor heating systems it helps to reduce energy consumption.
