Quietflex ss0880 Insulation Sleeve 8 in X 5 Ft R8.0

Product Description

The QUIETFLEX ss0880 is an 8-inch diameter, 5-foot insulated sleeve designed to wrap new or existing hard pipe ductwork in residential and light commercial HVAC systems. Rated at R8.0, it reduces heat gain and heat loss through exposed duct runs, improving the efficiency of conditioned air delivery. The sleeve features a reinforced metallic polyester vapor barrier that limits condensation buildup on cold duct surfaces. Licensed HVAC technicians and sheet metal contractors install this sleeve as part of duct insulation upgrades or new system commissioning.

The ss0880 is suited for applications where hard pipe ductwork lacks adequate insulation — including attic runs, crawlspace installations, and unconditioned mechanical rooms. Its 8-inch diameter fits standard 8-inch round metal duct. The R8.0 thermal rating meets high-performance insulation requirements common in energy codes for unconditioned spaces. Each box includes one starter cap, supporting a clean, complete installation on a single duct section.

Key Features

• R8.0 insulation value for high-performance thermal resistance on hard pipe duct runs
• Reinforced metallic polyester vapor barrier reduces condensation buildup on duct surfaces
• Standard 5-foot length fits typical residential duct section intervals
• 8-inch diameter fits standard round hard pipe ductwork
• One starter cap included per box for complete single-section installation
• Also available in R4.2 and R6.0 ratings and in boxed packaging for jobsite convenience

Compatibility

Designed as an insulation sleeve for 8-inch round hard pipe ductwork in residential and light commercial forced-air HVAC systems where exposed duct runs require thermal insulation and vapor control.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. Power down the air handling equipment before working on duct runs. Secure the sleeve ends with approved foil tape or mechanical fasteners per local energy code and SMACNA guidelines. Do not compress the insulation material, as compression reduces the effective R-value of the installed sleeve.
