Semi Rigid Expanded Insulation Cork Board

This all-natural cork board is one of the most environmentally friendly building materials available. Semi rigid expanded insulation cork board is produced from the natural cork granules created as the by-product of the stopper industry. These cork granules are steam-heated which causes the cork to expand activating suberin, a natural binder that is in the cork. No other binders or chemicals are added.

A light-weight, multi-functional, green building material
