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. Seal with reinforced HVAC tape (sold separately).
Commonly used in furnaces and engine compartments, these flexible silica fiber sheets resist corrosive acids. They perform best at temperatures above 1000° F.
Install these adhesive-back sheets to reduce noise from vibrating surfaces, such as duct and equipment housings.
Acrylic Plastic and Butyl Rubber sheets have an aluminum surface layer that helps resist corrosion.
Plastic sheets resist oil and grease.
