Check out our cartoon below about what makes ThermaCork Carbon Negative!

Harvesting cork is a time-honored, sustainable tradition handed down generation to generation.  See cork bark being harvested from the cork oak trees in Portugal's Montado Region and learn from the experts about the sustainability of cork. The cork bark will be made in to cork stoppers, cork flooring, and much, much more!

Cork Harvesting & Production: A 100% Eco-Friendly Process

The harvesting and production of cork is not only sustainable, but it also serves to provide employment and economic purpose for many communities. Cork harvesting is an ancient tradition, using the same method for thousands of years. It is done by hand for two months a year – June and July – when a skilled cork harvester splits off the bark of a cork oak tree without damaging the rest of the tree. Each tree can live between 150 and 250 years, and is harvested every nine years – at least 15 times during its life. No other tree can support and flourish from this process, and cork tree harvesting actually improves the tree’s health and vigor. Furthermore, more than 100,000 individuals in the Western Mediterranean and Northern Africa regions depend on the cork industry for their livelihood. 

After harvesting, the removed bark is dried in the sun, and handled differently depending on its use. Expanded Insulation Cork Board is produced from the natural cork granules which are steam-heated, causing the cork to expand. This activates suberin, a natural binder, thus requiring no added binders or chemicals during the production of insulation cork. Facade Cork is made in the same way, though utilizes different, and slightly superior, parts of the cork product for a smooth and more attractive appearance. Throughout the production process of both products, absolutely nothing is wasted. All waste is returned to the production process, making cork harvesting and production one of the most sustainable business practices on the planet.

This video truly showcases the extremely efficient, carbon negative manufacturing process of ThermaCork.

Albert and his wife Eva Rooks took a vacation to Portugal to check out the cork biofuel power plant that supports our cork insulation here in the US. For more of Small Planet's work, products, and info visit: thesmallplanetworkshopstore.com 

Why Use ThermaCork Standard 

Insulation in Construction?

 

It's the Natural Choice

It's a 100% natural product that supports cork forests, which in turn host a wide range of plants and animals, support local economies, and help reverse planetary damage by absorbing carbon dioxide in the atmosphere and avoiding soil desertification. Once produced, the finished product actually has a negative carbon footprint. The process of production, from harvest to production, is one of the most sustainable sustainable business practices on Earth.

It's an Energy Saver

Cork insulation will drastically reduce energy consumption, and its energy saving qualities will last decades, far longer than most choices. This is due to cork's high insulating range, stability, and its reduction of thermal bridging. 


Superior Qualities

Cork is incredibly stable and can cope with major thermal variations, between (-) 292 degrees F to (+) 248 degrees F. It's hypoallergenic and free of all domestic toxins, all while preventing mold by its ability to "dry through" layers. It's high on the insulating range (R-4 per inch), reduces thermal bridging, and its thermal resistance does not decrease over time like man-made foam. It has excellent sound isolation, is dimensionally stable, and resistant to compression.

Permeability: 

  • 1 1/2" thickness:2.15 US perms
  • 2" thickness: 2.04 US perms
  • 4" thickness:1.26 US perms

Maximum Moisture Content: 8%, with water absorption declared at 0.5 kg/m3

Anti-vibration Qualities

The ability of a material when subjected to loads have a natural tendency to recovery (resilience) to help prevent the spread of vibration over a given surface to be transmitted to the contiguous space. ThermaCork has a recovery to the original thickness of about 98%, which allows the application in these situations.

A Greener, More Sustainable World

In order to build a better world, it will require us to rethink our collective and personal daily choices and behaviors, including how we conduct business. Numerous individuals in the building industry are already rethinking their way of doing business. From architects to designers to builders, many are working tirelessly to create innovative architectural designs, tools, and techniques for a greener industry and greener world.

What is ThermaCork, Anyway?

ThermaCork is a 100% natural, renewable, recyclable, and biodegradable product made from the outer bark of an oak tree, a species called Quercus suber. Cork trees grow primarily in the cork forests of the western Mediterranean, but over 55% of the world's cork production originates from the nationally protected forests of Portugal. In fact, the cork tree even serves as the Portuguese national symbol. One of the most versatile materials on Earth, cork can be used for a wide range of products. Though cork has existed over a century as a building material, the eco-sustainable wave has popularized its use further.

 

Cork Forests: Environmental Benefits

Cork forests are one of the last natural habitats, and host a wide range of indigenous - and even endangered - mammals, birds, and plant species. Cork forests are considered biodiversity hotspots, providing food, shelter, and feeding groups for a number of species. One of the most beneficial aspects of cork forests are their ability to reverse environmental damage. They protect soil from desertification by protecting against wind erosion and also serve as a natural fire barrier, reducing the risk of forest fires. Another major benefit of cork forests is their ability to act as "carbon sinks", capturing greenhouse gases and CO2 in the atmosphere. In fact, cork forests in Portugal trap 4.8 million tons of CO2 emissions a year! 

 

Officially Recognized

ThermaCork has been Officially Recognized as one of the Top 10 Green Building Materials available today by Building Green, the Authority on Environmentally responsible building design and construction!

 

10 Year Total Replacement Warranty

In the off chance that there is something wrong with the cork, the manufacturer guarantees it being free from material or production defects for 10 years. Within that 10 year period, if it doesn't perform the way it should, the manufacturer will replace the defective cork or reimburse the product’s cost.


SIGA Compliant 

ThermaCork has been recently tested by SIGA Cover to ensure ThermaCork meets the requirements needed to function with their entire line of Wigluv, Fentrim and Primur products for all of your air-tight sealing needs!
