Categories:	Other Engineering Material
Material Notes:	Fiber-free, elastomeric duct liner for round ducts. This product is a fiber-free elastomeric duct liner for spiral ducts, considered to be the most efficient ducts made. An easy-to-cut, flexible olefin backing is pre-laminated to the foam and shipped in convenient rolls. Fiber free and easier to clean than fibrous duct lining Good at attenuating airborne noise from HVAC systems Ducts with AP Spiralflex liners are 20% lighter than dual wall ducts. This can translate to cost savings in duct hangers, construction supports and other building costs Simplified one-step installation: Eliminates costly encapsulating films and the inner metal wall for round ducts ASTM E 84 25/50 rated for smoke and flame Information provided by Armacell®
