Thermafiber, Inc., headquartered in Wabash, Indiana, is one of the largest manufacturers of mineral wool in the Americas, serving the insulation industry since 1934. Mineral or 'rock' wool is produced from blast furnace slag, a by-product of the steel industry, and other naturally occurring rock. These raw materials are melted in a cupola furnace at temperatures above 2600 degrees F, spun into fiber, and either left loose (granulated) or formed into an insulating blanket or board. Thermafiber products are also considered 'green' due to the fact that we offer products with a pre-consumer recycled content of up to 90%. Since our mineral wool is made from slag and/or rock, so it has a higher density than conventional glass fiber batts. This higher density contributes to superior acoustical performance when isolating mid to high frequency (speech and music) sound sources. Because our fibers are Born In Fire, they resist temperatures in excess of 2000 degrees F. That is why our products are commonly used in high temperature applications and fire rated construction. As pioneers in high-rise perimeter fire containment systems, Thermafiber curtain wall and safing insulation products are among the most specified perimeter fire protection insulations and have been installed in the world's tallest buildings. Thermafiber products are sold to construction markets, power and process markets, and a wide variety of industrial and OEM markets. Thermafiber also provides specialized fabrication, offering a variety of shapes, sizes and facings to fit custom applications.
