Duct Liner (optional):

1.5″ ‐ 2″ thick fiberglass which meets flame spread and smoke developed ratings requirements set forth in NFPA 90A.

Fabrication:

Ductwork is formed from a coil of galvanized metal. Standard or SMACNA gauges are available, based on your specifications. Seams are snap lock or Pittsburgh. Connections are slip & drive, TDC, or bolt connector. Ductwork can be produced in a one piece assembly or in an “L” shape, depending on size.

Fittings are manufactured of galvanized or paint grip metal with a lock seam or lap seam (i.e., tacked welded, solid weld, or riveted). These may be with or without duct sealant. Gauges are standard or SMACNA, based on your specifications.
