Cork Sheet is a natural, versatile material made from the bark of cork oak trees. It is used for insulation, soundproofing, and as a protective layer in various applications. Cork sheets are lightweight, resilient, and eco-friendly, offering excellent thermal and acoustic insulation properties. Cork sheet is also moisture-resistant and can be used in flooring, wall coverings, and bulletin boards.
