Quietflex ss0660 Insulation Sleeve 6in X 5ft R6.0

Product Description

The QUIETFLEX ss0660 is a pre-formed insulated sleeve designed to wrap over new or existing hard pipe duct sections, providing R6.0 thermal insulation in a 6-inch diameter by 5-foot length format. It reduces heat transfer along the duct run, helping warm or cool air arrive at the register closer to its intended temperature. The reinforced metallic polyester vapor barrier controls condensation on the outer duct surface, which is a common issue in humid environments. HVAC technicians install this sleeve during new construction or as a retrofit on exposed rigid duct runs in attics, crawl spaces, and mechanical rooms.

This insulation sleeve suits residential and light commercial HVAC duct systems where hard pipe needs thermal and vapor protection. It is particularly useful in unconditioned spaces where temperature differentials drive condensation and energy loss. The 5-foot standard length works for individual duct segments, and the included starter cap simplifies the termination of each run. The silver metallic facing is compatible with standard duct wrap installation practices used in forced-air heating and cooling systems.

Key Features

• R6.0 insulation value for effective thermal performance on hard pipe duct
• 6-inch diameter x 5-foot length fits standard rigid duct sections
• Reinforced metallic polyester vapor barrier reduces condensation buildup
• One starter cap included per box for clean duct terminations
• Also available in R4.2 and R8.0 insulation ratings for different application requirements
• Available in boxed packaging for clean jobsite handling and storage

Compatibility

Designed for use on new or existing rigid hard pipe duct sections in residential and light commercial forced-air HVAC systems requiring field-applied insulation sleeves.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Power down the air handling equipment before working on or near duct sections. Slide the sleeve over the hard pipe duct and secure ends per local mechanical code requirements, referencing applicable sections of the International Mechanical Code for insulation continuity and vapor barrier integrity. Do not compress the insulation material, as compression reduces the effective R-value.
