Quietflex SS0860 Insulation Sleeve 8in X 5ft R6.0

Product Description

The QUIETFLEX SS0860 is a pre-formed flexible insulation sleeve designed to wrap around hard pipe duct runs in residential and light commercial HVAC systems. Rated at R6.0, the sleeve reduces heat transfer along supply and return ducts, improving the efficiency of both heated and cooled airflow. The reinforced metallic polyester vapor barrier limits condensation buildup on cold duct surfaces, which is critical in humid climates or unconditioned spaces such as attics and crawlspaces. Each box includes one starter cap for a clean, complete installation at the duct end. HVAC technicians and sheet metal installers work with this sleeve on new construction and retrofit applications alike.

The SS0860 is sized for 8-inch round hard pipe duct and comes in a standard 5-foot length. It is suited for residential forced-air systems and light commercial installations where existing or newly installed galvanized or sheet metal round duct requires insulation to meet energy code requirements. The R6.0 rating satisfies common energy code minimums for duct insulation in conditioned and semi-conditioned spaces. The product is also available in R4.2 and R8.0 ratings for applications requiring different thermal performance levels, and in 10-foot custom lengths for longer uninterrupted duct runs.

Key Features

• R6.0 thermal rating reduces heat gain and loss along duct runs
• Reinforced metallic polyester vapor barrier controls condensation buildup
• Fits 8-inch round hard pipe duct — residential and light commercial use
• Standard 5-foot length with one starter cap included per box

Compatibility

Designed for use on 8-inch round hard pipe duct in residential and light commercial forced-air HVAC systems requiring insulation of supply or return duct runs.

Installation Notes

Installation is typically performed by a licensed HVAC technician or sheet metal contractor. The HVAC system should be shut down and the air handler de-energized before working on duct runs in enclosed or overhead spaces. Verify local energy code requirements for minimum R-value on supply and return ducts before selecting sleeve rating. Secure sleeve ends with approved mastic, foil tape, or mechanical fasteners as required by local mechanical code.
