The #1 Flexible Duct in the World.

Floating Core Residential Product Line

Thermaex’s NEW patent pending Floating Core (FC) Duct Construction adds a wire helix

spacer between traditional bulk insulation and the reective 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 exible 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 classied 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.
