Product

Green Cork Holdings, LLC, an Arizona-based company, has developed a product, Green Cork Spray™, which uses cork as a spray addressing four major market areas:

• Residential and commercial replacement for cement-based stucco
• Sound abatement
• Fireproofing
• HVAC thermal protection

Green Cork Spray™ is “Made in America” with material provided through an exclusive agreement with the world’s leading provider of cork, Amorim Composites in Portugal. www.amorim.com

Cork is one of nature’s most extraordinary materials. Cork is the outer bark of the cork oak tree. One hundred percent natural, reusable, and recyclable, cork is, whether from the environmental, social, or economic perspectives, one of the world’s most versatile materials. It takes each cork oak 25 years before it can be stripped for the first time, which becomes the raw material for Green Cork Spray™. Cork is harvested every nine years without any tree being felled. The cork oak is the only tree whose bark regenerates, acquiring a smoother texture following each harvest. Over the course of its lifetime, which on average lasts 200 years, it may be stripped around 17 times.

Key characteristics of Green Cork Spray™:

• Excellent Thermal Insulation: the air inside the cork cells makes it an excellent insulator, leading to very low thermal conductivity over a wide range of temperatures.
• Excellent Resistance to Fire and High Temperatures: Cork is also fire retardant. It burns without a flame and does not emit toxic gases during combustion.
• Excellent Elasticity and Compressibility: It is the only solid which, when compressed on one side, does not increase in volume on another; and as a result of its elasticity, it is able to adapt, for example, to variations in temperature and pressure without suffering alterations.
• Extremely Light and Buoyant: Over 50% of its volume is air, which makes it very light – it weighs just 0.16 grams per cubic centimeter and can float.
• Hypoallergenic: Because cork does not absorb dust, it helps protect against allergies and does not pose a risk to asthma sufferers.
• Impermeable to Liquids and Gases: Thanks to the suberin and ceroids contained in the cell walls, cork is practically impermeable to liquids and gases. Its resistance to moisture enables it to age without deteriorating.
• Comfortable and Warm Feeling: The natural texture of cork combines softness and flexibility to the touch with a naturally uneven surface.
• Excellent Acoustic Insulation: Cork has low conductivity to noise and vibration. This is because the gaseous components contained in cork are enclosed in small impermeable compartments, isolated from each other by a moisture-resistant substance.

Green Cork Spray’s™ cork ingredients come from cork forests that are natural CO2 retainers, the major cause of global warming. It is estimated that every year cork oak forests retain up to 14 million tons of CO2, a sizeable contribution to reducing greenhouse gas emissions. Equally surprising is the fact that the cork oak increases its ability to absorb these gases during the natural regeneration process following stripping. The more it is harvested, the more the cork tree protects the environment.

Green Cork Spray™ is fully certified in North America for use in the United States and Canada and has several active demonstration sites underway in Arizona and California. Green Cork Spray™ can be blended to any color desired.
