How are expanded cork granules made? Zero waste!

It's a sustainable process. First, we heat natural cork grains in special moulds to very high temperatures. The cork particles expand during the process of heating – just like popcorn. That's how the natural material acquires improved properties compared to other products or even a traditional form of natural cork. During the production of expanded cork, the material releases a resin (suberin), which naturally binds all the particles. Expanded cork granules are made from products that have not been used in the production of the insulation boards made from expanded cork.
