Cork has several advantages, thanks to its unique chemical composition and structure, including the following:

  • Lightness

Almost 90% of the volume of cork is air, so it is extremely light, weighing between 0.12 and 0.24 quarts per pound.

  • Elasticity

Cork regains its volume after being damaged.

  • High Friction Coefficient

 Cork won’t slide, thanks to the micro suction cups on its surface.

  • High Impermeability

Plasmodesmata allow vapors to easily escape, but liquids and gasses can’t get in. 

  • Fire Retardant

 Cork won’t release incandescent particles and won’t propagate flames. 

  • Absorbs Impacts

The force of an impact spreads outwards to protect the surface.

  • Regression Coefficient

Stretching cork causes no deformation in the perpendicular direction.

  • Ease of Use

 Changing the water content allows cork to become softer.  

  • Low Water Content

 A moisture balance with the environment of 6% makes cork an inhospitable home to pests and microorganisms.

  • Thermal Insulation

 In nature, cork functions to protect the tree that it comes from. With a temperature range of 32 °F to 85 °F, cork resists heat up to 30 times better than concrete.

  • Acoustic Insulation

 Cork cuts sound by 8 to 12 decibels, and the effect doubles if it is applied to more than one surface.

  • Non-Toxic

 Cork is completely non-toxic.

  • Balance with Nature

Cork trees last up to 500 years. They are cut for the first time at 40 years and only cut every 9 years after that.

  • Habitat Protection

 Cork trees act as protection for flora and fauna.

  • Environmental Improvement

 When cork bark is trimmed from trees, oxygen is released into the environment.

  • Ecological Sustainability

 There are no environmental impacts from extraction, manufacturing, or applying cork.

Modern times call for forward-thinking solutions to reduce our carbon footprint and build a healthier planet. When it comes to insulation, the answer is cork.
