The corkboard material is a natural product (vegetal) originating from cork. The cells of the expanded cork, contain 50% of air, are waterproof and are expandable. The Corkboard is not only a thermal but also a phonic and vibratic insulator.
The cork granulates are placed in a pressure cooker, heated to a temperature of 300°C and without any contact with the air. The blocks are then removed and cooled. Afterwards they are sawn to the dimensions required. After cleaning the fibres are compressed into sheets.
Applications for the corkboard are insulation of walls, floors, ceilings, refrigerators, pipes, doors. It is also used against steaming condensation and structure and machine vibrations, as gaskets, for acoustic correction, etc.
