The Cork


Elastic, compressible, and resilient

Cork is the only solid that, when compressed on one side, does not increase in volume on the other. Furthermore, it possesses an ‘elastic memory’ that allows it to adapt to temperature and pressure variations. This characteristic is due to the gaseous mixture within each cell, which enables it to be compressed to about half its thickness and then decompressed, returning to its original shape.

Renewable, recyclable, and reusable

Cork is a renewable, recyclable, and reusable raw material.


As a natural product, cork is 100% biodegradable.

Energy Source

Cork dust can be used as biomass, serving as a carbon-neutral source of energy in terms of CO2 emissions.

Thermal, sound, and anti-vibration isolation

Cork has low thermal conductivity, sound, and vibration insulation properties. This is because the gaseous components contained in cork are enclosed in small, impermeable compartments that are isolated from each other.


Over 50% of cork’s volume is air, making it very lightweight, weighing only 0.16 grams per cubic centimeter, and allowing it to float.

Fire retardant

The slow combustion of cork makes it a natural fire retardant. Cork is, therefore, a natural barrier against wildfires. Cork burns without flame and does not emit toxic gases during combustion.


Thanks to suberin and ceroids contained in cell walls, cork is impermeable to liquids and gases. Its resistance to moisture allows it to age without deteriorating
