""Stoppers are our main business, but we produce different types of products as Amorim Cork Solutions, and one of these is expanded cork insulation," says Edgar Nadais, head of sales to the construction industry. "We take the branches of the tree, which are not used to produce the stoppers, and we make these into granules which are then treated with heat and pressure in an autoclave.""
""This process extracts the cork's resin, which acts as a natural binder to form the cork into a solid piece. "We cut the blocks into several thicknesses to suit different purposes, mainly for use as insulation," says Nadais. "From the raw material to the final block, the whole process takes about 20 minutes." This efficient use of waste cork is one reason why expanded cork insulation is considered an eco-friendly alternative to other materials such as mineral wool.""
Cork insulation is derived from cork oak branches and waste cork left over from bottle-stopper production, formed into granules and expanded. Branches not suitable for stoppers are ground into granules, then treated with heat and pressure in an autoclave to extract natural resin that binds the granules into solid blocks. Blocks are cut to various thicknesses for insulation uses. The full production cycle from raw material to final block takes about 20 minutes. Efficient use of waste cork reduces intervention and makes expanded cork a low-impact alternative to materials such as mineral wool. The material offers thermal and acoustic insulation benefits.
