Datasheets & Downloads
Thermaflex EverClean Flexible Insulated HVAC LEED Duct- 4 inch Diameter- 25 Ft. Length
EverClean™ is designed for use in custom built homes where improved indoor air quality (IAQ) is desired or required. EverClean flexible ducts perform well in low to high pressure cooling and heating systems and can be utilized in either supply or return sections. Specific applications include branch ducts and branch connections to or between mixing units, induction units, control or terminal units, and diffusion devices.
NFPA Standards Compliance allows installation lengths longer than the normal connector limitation. And EverClean provides excellent efficiency in higher-pressure systems because its liner and reinforced, metallized vapor barrier work in combination to supply a double air seal.
No other residential flexible duct comes close to EverClean's feature package. For homeowners, builders and HVAC contractors who want a superior IAQ product, EverClean comes Greenguard-certified and features a lifetime warranty to the original homeowner.
- Designed to prevent mold and mildew growth, EverClean ducts are GreenGuard™ certified and meet stringent IAQ standards.
- Increasing duct insulation reduces energy bills, and provides constant comfort.
Improved Indoor Air Quality
- Insulated ducts reduce condensation and resulting mold growth.
- The fiber glass core serves as an excellent acoustic insulator.
- Thermaflex now provides a lifetime warranty to the original homeowner.
Fire Retardant Inner Core
- Duct components are flame-resistant and self-extinguishing.
