LAMELLA is manufactured with perpendicularly-oriented mineral wool bonded together with a high temperature binder. The end grain of the fiber is adhered to a facing surface, making it easy to wrap while providing a high compressive strength. LAMELLA is ideal for insulating pipes, cylindrical ducts, storage tanks, and equipment ranging in temperature from -20° F (-29° C) to 1000° F (538° C)
