Quietflex 14MR8 Insulated Pipe Sleeve 14in R-8 5ft

Product Description

The QUIETFLEX 14MR8 is an insulated pipe sleeve rated at R-8 and measuring 5 feet in length with a 14-inch diameter. It is designed to thermally insulate round ductwork and piping in HVAC systems, reducing heat gain or loss across unconditioned spaces such as attics, crawlspaces, and mechanical rooms. The R-8 insulation rating meets current energy code requirements for duct insulation in many jurisdictions. HVAC technicians install this sleeve over existing pipe or duct sections to improve system efficiency and limit condensation on cold surfaces.

This pipe sleeve is suited for residential and light commercial HVAC applications where large-diameter round duct or piping runs through unconditioned spaces. The 14-inch diameter accommodates correspondingly sized supply or return trunk lines. The 5-foot section length allows for straightforward installation in standard joist bays and mechanical chases without excessive field cutting. It is a common component in new installations and retrofit insulation upgrades on existing duct systems.

Key Features

• R-8 insulation rating meets energy code requirements for duct insulation in many climate zones
• 14-inch diameter fits large-diameter round duct and pipe sections
• 5-foot section length reduces the number of joints needed across long runs
• Sleeve design allows installation over existing pipe without full duct tear-out
• Suitable for controlling heat gain, heat loss, and condensation in unconditioned spaces

Compatibility

Designed as an OEM-style insulation sleeve for 14-inch round duct and piping systems in residential and light commercial HVAC installations.

Installation Notes

Installation is typically performed by a licensed HVAC technician. Power down the air handling system before working in tight mechanical spaces. Secure sleeve joints with foil tape rated for duct applications to maintain the thermal and vapor barrier integrity of the assembly. Follow local energy codes and ASHRAE standards for insulation continuity and joint sealing requirements.
