The pure cork is made by processes of heating and steaming whereby cork granulates are molded into a block. The natural resin of the cork acts as a bonding agent. An artificial bonding agent is required for the production of agglomeration cork. Cork is typically used for acoustic and thermal insulation within walls, floors, ceilings and facades.
The findings indicate that increasing the amount of cork aggregate increases moisture retention, with water buffer values ranging from 0.39 to 1.2 g/(m 2.%HR) and water vapour permeability ranging from 2.7 × 10 −12 to 21.4 × 10 −12 kg/(m s Pa) as density decreases. Cork concrete can be used as a thermal insulator, according to these reports.
Harvesting of cork from the forests of Algeria, 1930. Cork is a natural material used by humans for over 5,000 years. It is a material whose applications have been known since antiquity, especially in floating devices and as stopper for beverages, mainly wine, whose market, from the early twentieth century, had a massive expansion, particularly due to the development of several cork-based ...

It is typically smooth and shiny, but can also come in textured varieties, in which case it can sometimes be used as a cheap alternative to veneer .
Homasote contains no adhesives. It is held together by the surface tension between the paper fibers, a process that is augmented by hydrogen bonding and the presence of a wax binder (2% volume). It is available in multiple thicknesses and comes in sheets 4 by 8 feet (1.2 by 2.4 m).
Quercus suber, commonly called the cork oak, is a medium-sized, evergreen oak tree in the section Quercus sect. Cerris.It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls.
