Flame-Resistant Flexible Synthetic Fiber Insulation Sheets for Ducts
 |
Also known as fire wrap, these flame-resistant sheets meet ASTM E84 0/0 for flame and smoke and create a fire barrier around rectangular and round ductwork. They are often used to wrap kitchen grease exhaust ducts and air ducts.
