Percussion noise insulation consists in reducing the noise level of impact noises on the slabs, transmitted to the floor immediately below. For an effective reduction, it is necessary to guarantee a total independence between the floor and the property´s flooring and structure. The interposition of an elastic element, expanded cork agglomerate, between the flooring and the slab, produces a reduction in the transmission of vibrations and noises resulting from impacts. It will also be important to maintain the discontinuity between the flooring screed and the surrounding walls, thereby eliminating marginal transmissions.



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.
