DELTA® METAL MESH Blankets are manufactured by enclosing mineral wool {bonded together with a limited amount of high temperature binder} between various combinations of metal facings. It is a highly efficient, semi-flexible insulation recommended for industrial applications up to 1200°F.*(649°C*). DELTA® METAL-MESH Mineral Wool Blankets have a wide range of applications including use on high temperature expansion joints, coke drums, power and process equipment, and where withstanding extreme shocks and vibration are desired. Generally, attachment is by means of weld pins and clips, or strapping, and then finished with either metal, plastic lagging, or reinforced mastic.
