Hi!.🌞

Cork is the bark of the cork oak (Quercus suber), a plant tissue that in botany is called phelema and covers the trunk of the tree. Each year, a new peridermis grows – formed by rings that grow from the inside to the outside of the cork oak – which overlaps the older ones, thus forming this bark.

Features:

  • Lightness: due to the fact that 88% of its volume is air, which translates into a low density.

 

  • Elasticity: elasticity is the capacity to recover the initial volume after undergoing deformation, which justifies, among other things, its use as a covering.

 

  • High friction coefficient: the surface of the cork is covered with micro-suction cups that give it great adherence and make it difficult to slide.

 

  • Impermeability: the diffusion of liquids and gases through cork is very difficult, thanks to the suberin and ceroids present in the walls of its cells, cork is practically impermeable to liquids and gases.

 

  • High calorific value: the capacity of cork to generate heat is equivalent to that of charcoal, around 7000 Kcal/kg.

 

  • Easily handled: by artificially modifying the water content of cork, for example by boiling, industrial processes are facilitated, mainly cutting, as it becomes softer and more elastic.

 

  • Low water content: the equilibrium humidity of the cork with the environment, once the scrape has been removed, does not exceed 9% of its weight, normally 6%. This low humidity makes the proliferation of microorganisms impossible.

 

  • Thermal insulator: cork’s natural function is to protect the living parts of the tree that generates it. Its alveolar structure (preventing air circulation), its low water content and the lack of conductivity of its compounds allow it to fulfill its insulating function effectively. It presents a resistance to the passage of heat thirty times higher than concrete.
