N-20T Compressible Insulation Board

Pyrotek has developed N-20T for use as a non-asbestos lehr roll cladding material for the glass industry. Its excellent characteristics allow for the manufacture of a very durable, smooth, hard roll surface which is non-marking to glass. N-20T has out performed comparable materials and it has been approved for use by the major U.S. glass manufacturers. N-20T has also been proven to work well when a high-temperature compressible gasket is required.
