One of the characteristics that make the Expanded Cork Black Agglomerate an ecological product is its ability to be recycled. The result of this recycling is the granulate of expanded cork, which is obtained from the grinding of the Black Cork Agglomerate.
Cork regranulate can be used in direct incorporation into concrete, creating a light concrete, making residential floors more lightweight with thermal and acoustic advantages. The filling of air gaps on flooring is also a use of the cork regranulate, providing acoustic and thermal correction.


The Expanded Cork Agglomerate, internationally called “INSULATION CORK BOARD” or ICB, is a product of plant origin that comes from the falca, which is a very specific type of cork. This cork comes from the pruning and cleaning operations of cork oaks. After the falca extraction, it is crushed to separate the gravel and later granulation. The falca granules are placed in autoclaves and expanded by the action of water vapor.
Since the grains are confined to the space of the autoclave and have nowhere to expand, they become a block of agglutinated grains by means of the released resin.
Once stabilized, the Expanded Cork Agglomerate blocks are sawn in different thicknesses and packed in order to be placed in different markets.
The Expanded Cork Agglomerate is a 100% renewable product that provides an energy saving, with corresponding increase in comfort, provided by a natural and sustained isolation that does not compromise the needs of future generations.
