SKU: fd5x25flex
$107.00Description
- The Lambro Industries 5x25flex Flexible R-4.2 Insulated Air Duct Hose is an industrial-grade, commercial-grade equipment component engineered specifically to ensure efficient thermal airflow delivery and sound attenuation across demanding forced-air system environments.
- Fabricated from a premium laminated metallized polyester inner core encapsulating a tough galvanized steel wire helix, this high-performance layout handles continuous operational airflow velocities while permanently resisting core unravelling, mold formation, and structural jacket wrinkling under pressure.
- The innovative triax fiberglass scrim reinforced black vapor barrier and thick fiberglass insulation blanket significantly improve thermal efficiency to smoothly handle atmospheric branch distribution tasks without causing outer surface duct sweating, thermal convection losses, or audible branch noise rattle.
- Ideal for licensed HVAC/R technicians, mechanical contractors, and multi-family residential building supervisors, this durable flexible duct features a highly compressible architecture to rapidly execute clean, direct field installations, maximize overall energy efficiency, and permanently eliminate expensive thermal loss callbacks.
