Ductmate 12820GA Insulated Round Duct
This insulated round duct serves HVAC systems requiring thermal protection up to 200 °F. It fits nominal diameters of 19 in and 20 in with a 22 ga wall. The sandwich-style construction uses fibreglass insulation to reduce heat loss and condensation in commercial or residential installations.
Suited for standard 19 in
Builders working with other diameters or requiring a fire-rated assembly should look elsewhere. Systems demanding a higher temperature rating or a different insulation material will not be served by this model. The fixed 22 ga thickness also limits use where heavier gauge metal is specified.
22 ga wall thickness with 200 °F rating
The 22 ga steel shell and fibreglass insulation combine to handle continuous temperatures up to 200 °F. This single specification determines whether the duct meets the thermal and structural demands of the project. Verify the nominal diameter matches 19 in or 20 in before ordering.

Questions about this item
What duct diameter must the existing opening match for the 12820GA to fit?
The access door is designed for nominal duct diameters of 19 in and 20 in, so the round duct opening must match one of those sizes.
Will the 22 ga door frame and 2 in mounting studs align with older ductwork of the same gauge?
Yes, the 22 ga material thickness and 2 in stud length are standard for this diameter range, allowing direct mounting to compatible existing duct sections.
How can I confirm the door seals correctly after installation at the 200 °F rating?
After mounting the two studs and tightening the knob latches, inspect the fiberglass-insulated panel for even compression and verify no air leakage around the 12 in × 8 in rectangular opening.
