Noncombustible Insulwool Blanket - 1" Thick

Used to enclose the space between existing chimney & new liner to eliminate cold air infiltration


 INSULWOOL-HP BLANKET was developed to meet the demand for a high temperature, flexible blanket insulation with a low iron content of less than 1%. INSULWOOL-HP BLANKET has excellent strength, both hot and cold. It remains in place on the furnace anchors even at high temperatures and can resist damage even when subjected to normal mistreatment in shipment and handling. If INSULWOOL-HP BLANKET becomes wet from water, steam, or oil, its thermal and physical properties are restored upon drying. Its sound absorption ability is greater than dense or insulating refractories and it stores some 95% less heat than dense firebrick and about 75% less than insulating brick. INSULWOOL-HP Blanket is NOT approved for Fire Safety or Food/Cooking Linings.
