Composition cork rolls and sheets are perhaps the most versatile of all cork products. Manufactured from natural cork grains, they maintain most of the same characteristics attributed to cork in its natural state. They are great for bulletin and tack boards, gaskets and protective pads, underlayment and insulating material, coasters, hot pads, model, crafts and hobby needs, and much more. Indentations created by the use of push pins will naturally "heal" to allow an attractive smooth finish to display your items and it can be cut to any shape or size required. Comprised of a thin layer (1.2mm) of fine grained cork adhered to a fibreboard backing, the total thickness for this cork and backing combined is 1/2".
