Southwark Metal CBR8141422 Cube Closed Plenum R8 14 Inches X 14 Inches X 22 Inches with 2 Inches Liner

Product Description

The Southwark Metal CBR8141422 is a cube closed plenum designed for residential and light commercial HVAC duct systems. This unit measures 14 inches wide by 14 inches long by 22 inches tall and includes a 2 inches interior liner. It is built with an R8 insulation rating, making it suitable for installations that require higher thermal performance and energy code compliance. HVAC technicians and sheet metal contractors use closed plenums like this one to terminate or transition ductwork at air handling units, furnaces, and fan coil units. The plenum creates a sealed air chamber that helps direct conditioned air efficiently while reducing heat gain or loss through the duct walls. The CBR8141422 is constructed from galvanized steel at 26 gauge thickness. The galvanized finish provides corrosion resistance, which extends service life in both humid and dry environments. The 2 inches liner inside the unit adds acoustic dampening in addition to thermal insulation, helping reduce mechanical noise in occupied spaces. This closed cube design has no flange, which simplifies installation in tight spaces where flanged connections are not required. With a unit weight of 11 pounds and a cubic measurement of approximately 2.5 cubic feet, this plenum is manageable for single-technician handling on the job site. It ships as a single unit and is manufactured in the USA. Trade professionals looking for R8 insulated plenums, galvanized HVAC plenums, or closed box plenums for residential HVAC retrofit or new construction applications will find this unit meets common performance and code requirements. It is a reliable component for supply or return air plenum configurations at the air handler.

• R8 insulation rating meets energy code requirements for insulated ductwork in many jurisdictions
• 26 gauge galvanized steel construction provides durability and corrosion resistance
