Earthkweek developed a green roof system based on the expanded cork of Pro Suber. In this way they help to reduce the city’s temperature and temper the effect of heavy short term rainfall. By using the cork based system there will be a cooling effect in the summer and an extra layer with insulation capacity that would lower the heating costs in winter. The cork modules are grown in a various selection of thickness and choice of plants; like different sorts of sedum but also flower and herbs modules that will provide a natural habitat for bees, butterflies and other insects which will attract more birds. The cork used for these modules is 100% biobased and from a renewable source; the cork oak (quercus suber). Furthermore the modules are filled with both circular substrate and capillary mat of used clothing. The foil used under the modules is Biobased and instead of pebbles around the green roof borders there was chosen to work with natural dried ‘Peach-stones’. All plants are grown and nurtured on the farm without the use of chemical-products, and mainly native plants are used to help and support the local flora and fauna. In conclusion this cork based living roof can truly be called “a real green roof”. More info on

All the mentioned cork products consists of expanded cork, an excellent insulating material and 100% natural. The material is made by heating the cork granulate, which pops like popcorn, releasing a resin (suberin) that binds the granulate naturally.
