More about Expanded Cork Board Insulation

Cork insulation boards are made by exposing cork granules to super-heated steam in a block-shaped press mold. The super-heated steam causes the cork pieces to swell and expand, but because their movement in the press mold is limited, the granules are forced together under pressure. Suberin, a waxy resin naturally present in cork, is activated by the steam and pressure, and acts as a binder between the now expanded granules. After the molded blocks are cooled, they are cut into slabs of varying thicknesses. No flame retardant or antimicrobial additives are necessary.
