Thermaflex’s NEW patent-pending Floating Core (FC) Duct Construction adds a wire helix spacer between traditional bulk insulation and the reflective inner core creating a new and improved insulation system.
The addition of the wire helix spacer creates an air gap allowing the FC to be packaged up to 50% smaller than standard insulated flexible ducting. When unpacked, the Floating Core recovers 20% faster from the packaging allowing for quicker installation times.
The FC is a thermally insulated, fully lined, UL 181 Tested and Approved Class 1 Flexible Air Duct Construction that is also classified by Underwriters Laboratories using ASTM C-518 standard to determine thermal ratings. It’s designed for low to medium pressure cooling and heating HVAC systems.
The FC’s smaller packaging allows for more units to be combined on a single pallet. The pallet to the left shows 36 boxes of 6″ standard KM R8 Insulated Flexible Duct. The pallet to the right shows 60 boxes of the new 6″ KM-FC R8 Insulated Flexible Duct.
Strong polyester film laminated and encapsulating a heavy steel wire helix, forms the inner core. The outer silver film provides a reflective surface on the inner core. An oversized, loose, steel wire helix supports a thick blanket of fiberglass insulation creating an air gap between the reflective inner core and fiberglass insulation. The outer vapor barrier is a bi-directional reinforced metallized vapor barrier that will not unravel. The smooth airtight innercore of polyester is designed for low to medium pressure systems.
