Double Wall Insulated Round Duct

Double wall round duct mcgill airflow s double wall round duct is fabricated to exacting tolerances that make it easy to assemble and essentially leak free.

Double wall insulated round duct.

Double wall duct and fittings will consist of a perforated or solid inner liner 1 thick x 1 0 lb ft layer of glass fiber insulation and a solid outer pressure shell. In double wall round spiral duct a metal inner liner insures that high airflow velocities cannot separate insulation by pulling away from the duct s outer wall and creating erosion or airflow problems. Dual wall also called double wall insulated spiral pipe dual wall insulated spiral pipe consists of two concentric spiral pipes with insulation filling the space between the pipes. It is a kind of metal duct designed and produced to offer an excellent acoustical and thermal function for hvac ductwork applications.

Three standard types of double wall. Smc double wall round spiral duct is a dependable erosion resistant alternative to lined round spiral duct providing improved protection for insulation exposed to the airstream. It is shipped from the factory with the insulation pre installed reducing job site labor costs. This insulated duct provides excellent acoustical and thermal control with the efficient airflow performance of single wall round duct.
