Product Details
Thermaflex S-LD non-insulated flex ducts are an economical alternative where insulated ducts are not required, designed for low to medium heating and cooling systems. These HVAC ducts feature a reinforced metal film laminate jacket bonded to a corrosion-resistant steel wire coil, ensuring secure air sealing. The spiral ducts are constructed to prevent unraveling when cut and incorporate a self-extinguishing inner core that will not support flames. They operate effectively within a temperature range of -20°F to 250°F and are available in diameters ranging from 3" to 14". Additionally, these ducts are GREENGUARD certified and come with a 10-year limited warranty.
