Class 1 Flexible Air Duct Code Compliance: NFPA 90A & 90B, UL181 Reinforced, metalized polyester vapor barrier Airtite polyester inner core Standard lengths of 25ft Diameters 4″-20″ Available in R-4.2, R-6.0, or R-8.0
All thermal performance (R-Values) are classified by Intertek Laboratories in accordance with ADC Flexible Duct Performance and Installation Standards using ASTM C-518 (1991), at installed wall thickness, on flat insulation only.
Air Tight Inner Core
Double lamination of strong polyester encapsulates a steel wire helix.
Insulation
Formaldehyde- free Multi-thicknesses (R4,R6,R8) wraps the double layer inner core. Mold and mildew resistance. ECOSE non petroleum base binding Technology.
Jacket
Tough and durable Bi-Directional fiber reinforced metalized polyester jacket.
Royal Metal Flexible Duct Conforms to U.L. standard 181 for Class 1 Flexible Air Ducts, and is manufactured with a Bi-directional reinforced fiberglass scrim with a metalized out jacket. The three products have an air-tight inner core designed to operate at medium to low pressures in HVAC systems. The product is insulated to meet geographic building code requirements. Narrow wire spacing on core allows for low friction loss and low operating cost. Insulation Formaldehyde free, mold and mildew resistance with ECOSE Technology prevents itching when installing.
Product is designed for indoor use as a supply or return air duct in low to medium pressure residential and commercial heating and air conditioning systems. All three R values can be used to complete air duct systems’, branch duct, connecting to mixing boxes, diffusers, room inlets, or other devices. R factor requirements are determined by geographic building codes. UL 181, NFPA 90A & 90B
