How are cork floor tiles made from ground cork?

Cork floor tiles are manufactured by taking ground cork granules and subjecting them to heat. This process, which can involve either prolonged heating or rapid high-frequency heating, causes the granules to adhere to one another. The resulting material is a resilient mixture that is compressed and baked to form tiles, typically ranging from two- to five-sixteenths of an inch in thickness.12

These tiles are valued for their comfortable, resilient feel and their ability to absorb sound, though they are generally considered to have only fair durability and aesthetic properties.1
