About Cork
Cork is one of Mother Nature’s most extraordinary products. The all-natural material comes from the bark of the cork oak tree (Quercus Suber L.) and is composed fully of natural plant tissue.
Cork is a natural cellular material of biological origin with an interesting and unique combination of properties. It has low density, buoyancy, very low permeability, low thermal coefficients, elasticity, and withstands large deformation without fracture under compression. These properties are the reason for the material’s various applications, namely as a sealant and insulator.
Cork’s properties are the combined result of the features of its cellular structure, particularly its cell dimensions and topology, its cell wall ultrastructure, and the cell wall chemical composition. The chemicals in the cell wall include suberin, the major chemical component and cork’s fingerprint. Together, these properties define cork’s behavior.
What is Carbonized Cork?
Carbonized cork consists of a honeycomb of microscopic cells filled with air-like gas and coated mainly with Suberin and lignin. Other compounds are identified in its chemical composition, although in less quantity, such as polysaccharides, ceroids and tannins. A single cubic centimeter of cork contains almost 40 million cells – around 800 million in a single natural cork stopper.
The outer bark of cork wood is crushed, then the crushed pieces are placed in the mold and heat pressed at around 300°C temperature.
• We use 100% natural cork raw material only without any additives
• Corkboard are produced using 100% environmental friendly processes.
• 90% of production is using only biomass; organic and renewable source of energy
• Any wastes or scrap products are 100% recyclable.
• Strict quality measures are met by following EN131 72D & EN13170 standards
• Quality maintenance inspection is performed every 6months according to CSTB standards
Our promise to sustainable materials
Cortiça Garden uses 100% natural cork raw material without any additives, and they are produced using environmentally friendly practices. In fact, 90% of its production strictly uses biomass, an organic and renewable source of energy, and any waste or scrap products are 100% recyclable. In addition, quality maintenance inspections are performed every six months in accordance with CSTB standards.
Cork oak increases its ability to absorb the harmful Co2 gases during the natural regeneration process following stripping – a stripped cork absorbs, on average, five times more CO2 and the ability to retain carbon dioxide is also passed on to manufactured cork products, which continue to ensure this function to absorb CO2.
It is estimated that for every ton of cork produced, cork oak forests captures over 73 tons of CO2, a vital contribution for reducing greenhouse gas emissions, the main cause of climate change
