Firwin 1200 Insulation is a mechanically bonded glass fiber insulating blanket that provides reliable, superior performance at temperatures up to 1,200ºF. Manufacturing controls include use of carefully selected long glass textile fibers to ensure uniformity of mechanical bonding without additional binders and a finely engineered needling process that creates uniform insulating efficiency during extended exposure to elevated temperatures.

Firwin 1200 Insulation offers good drapability, conforming to irregular surfaces with ease. It is odorless, does not contribute to metal corrosion, and resists decay, mold, and vermin. It offers excellent sound absorption properties and resistance to vibration without powdering.
