Belt-shaped thermal insulation materials


MG BELT is made by cutting MG BOARD into strips and reinforcing it with cheesecloth.
The fibers stand upright in the thickness direction, and so it has excellent flexibility and is easy to wrap around pipes and circular ducts. Nichias’ product lineup also includes a cheesecloth-affixed product and an ALGC-decorated product.
