R4.2 Insulated Aluminum Flexible Ducting With Fiberglass And PET

Beyond its structural advantages, PET offers several key engineering benefits for HVAC applications:Non-toxic and heat-stable: PET remains stable under high temperatures and does not emit harmful gases during fire or overheating.Hygienic and clean: The smooth, non-porous inner surface prevents dust accumulation and microbial growth, ensuring clean air delivery.Low airflow resistance: The duct’s stable and smooth interior minimizes turbulence and pressure drop, improving overall system efficiency.Self-supporting: Once extended, the duct retains its shape without sagging—ideal for long or suspended runs.Easy installation: Lightweight, flexible, and easy to cut, suitable for confined spaces and modular layouts.High mechanical strength: PET provides up to 3–5 times the impact resistance of traditional duct liners.Superior barrier properties: Its low gas and moisture permeability prevents air leakage, condensation, and odor diffusion.Wide system compatibility: Suitable for high-, medium-, and low-pressure HVAC applications, including supply, return, and exhaust ducts.
