The origin of the material

The Expanded Insulation Corkboard was born of an accident.

In the year 1891 and the U.S. already imported large quantities of cork for the manufacture of many materials: cork stoppers, buoys, life jackets, and other materials. It was exactly in New York in a buoys and life jackets factory of John T. Smith that the recklessness took place ... At that time, the filling of lifejackets was done using a metal cylinder which allowed to keep the lifejacket open while the worker filled the cylinder with granulated cork. One of the cylinders was clogged and set apart and inadvertently rolled a brazier going unnoticed until the next morning.
The next day, Smith with the help of a worker while cleaning the ash from the brazier noticed that the cork inside the cylinder had not been burned, and the heat was sufficient to bind the entire mass in a single form-brown chocolate.
The original process was repeated intentionally to be able to prove that the material could bind without any additive foreign substances to cork and thus registering a patent on the manufacturing process.
