OUTSTANDING CHARACTERISTICS

This unique, natural raw material with its lightweight, flexible honeycomb structure, is impermeable to liquids and gas, which makes it an ideal material for a myriad of household products. Each cubic centimeter of cork contains between 30 and 40 million cells. The properties and essential characteristics of cork are derived naturally from the exceptional structure and chemical composition of these inner cells.

Insulation: Because 90% of the tissue consists of gaseous matter, the density of cork is extremely low, giving the material wonderful insulating properties; thermal as well as acoustical. 

Resilience: When cork is subjected to pressure, the gas is compressed and volume decreases considerably.  This action creates a comfortably firm but cushioned walking surface. 

Durability: Cork is remarkably resistant to wear due to its cellular structure.

Impermeability: The presence of Suberin, a natural, waxy substance, makes cork impervious to both liquids and gas which prevents rotting. 

Hypoallergenic: Cork does not absorb dust and, consequently, does not cause allergies. 

Fire Retardant: A natural fire retardant, cork does not spread flames or release toxic gases during combustion.
