As the corkboard owes its success to the cellular constitution of the cork; the cells contain 50% of air and have water-proof and expandable walls. When cork expanded in the pressure-cooker, does not lose these qualities but improves them. That is why the corkboard is so used in the building and construction industries.

Any type of corkboard is not only a thermal, Phonic or vibrational insulator. These characteristics considered all together give to the corkboard the exclusivity of being the unique natural product capable of acting in three different ways on insulations, but also a wide range of uses as follows:

* Thermal insulation of floors
* Thermal insulation of doors
* In interior decoration, serving also as insulator
* Against steam condensation
* As gaskets
* Insulation against the structures vibration
* Insulation against machine vibration

          *** Advantage***
The corkboard does not emit any of these gases and even regarding anhydride and carbon monoxide, the amount is so insignificant that there is no danger of poisonous action.

Hotels, schools, public or private building and refigured chambers the use of corkboard is an excellent life insurance, granting at least time to think.

when it is applied outside, eater has no corrosive effect on it. In laboratory tests a sample of corkboard placed in boiling water or in chloric acide for three consecutive hours, did not disintegrate.
