Thermal - Acoustic insulation
Cork is a natural product, non-polluting, difficult to combust, dimensionally stable, rot-proof, good insulator against electricity, resistant to rodents and insects, etc. It also stands out as the most important of all the properties of cork, which meets all at the same time and without detriment to any. Within these properties we will highlight some that make it suitable as a construction material.
Cork has physical properties that are a direct result of its air-filled cellular structure. Compressibility and resilience.
Cork in building construction
It has a low thermal conductivity: because the air that fills the cells is an excellent thermal insulator, since it delays the transfer of heat at low and moderate temperatures. This property together with the low density and resistance to pressure makes cork one of the best thermal insulators.
It also generates acoustic absorption: it is used as an insulator and of absortion against noise. The broken cells on the outer face of the cork form an ideal surface for absorbing acoustic waves. The resilience property of cork has made it an important tool in acoustic insulation. The air-filled cells of the cork receive vibrations, absorb them and reduce them so that they are not transmitted through the cork.
Aplications:
- Airborne noise insulation.
- Insulation to impact noise.
- Insulation to sound absorption.
- Reverberation time correction.
With these properties, the thermo-acoustic pure ecological black agglomerated cork and the BL-NAT Crudo ECO thermo-acoustic agglomerated cork stand out with these properties.
