Polyester R1.0 Insulated Flexible Duct
Description
SGS Polyester Insulated Duct Black PVC Outer Layer
The 6 inch insulated flexible duct (6 x 25 ft) is an R6-rated air duct engineered for HVAC systems in manufactured housing and
mobile home environments. This duct features a high-efficiency nonwoven polyester insulation layer, a double-layer aluminum
foil inner core, and a black PVC outer jacket, offering both mechanical strength and energy-saving thermal performance.
Its oversized core allows for a snug yet easy fit over standard collars and register boxes—reducing leakage and installation hassle.
Lightweight and pre-compressed, this 6 x 25 flexible duct R6 model is ideal for confined or retrofit HVAC layouts requiring both airflow flexibility and insulation reliability.

Why Choose Polyester Insulation?
As an R1.0 polyester insulated duct, this product delivers a clean, safe alternative to fiberglass while maintaining stable thermal performance. Polyester insulation is:
- Non-toxic and low-irritation – Ideal for residential or low-contact installation environments
- Structurally resilient – Maintains its shape after compression, preserving R-value over time
- Eco-conscious – More recyclable and cleaner to handle compared to glass-based insulations
The R6 rating makes this duct suitable for most HVAC applications, particularly when ducts pass through unconditioned zones or attics where heat loss can be significant.
Conclusion: A Professional Choice in Insulated Flexible Duct Work
When selecting ducting for temperature-sensitive or space-limited environments, the 6 inch insulated flexible duct with R1.0 polyester insulation and PVC jacket is a reliable, durable, and code-compliant solution. Designed for energy efficiency and installation ease, it meets the demands of modern HVAC system upgrades or new builds.
