Insulated Double Wall Spiral Duct MSSP® By ATRITUBE
Double wall spiral ducts are, as the name suggests, comprised of two walls. First, there is the larger duct that's visible to everyone. Next, there's the second inner spiral duct. These two components help ensure a more consistent airflow temperature during delivery.
Double Walled Spiral Ducts at Rs 1125/square meter Spiral Duct in
Double wall duct and fittings will consist of a perforated or solid inner liner, 1″ thick x 1.0 lb/ft³ layer of glass fiber insulation, and a solid outer pressure shell. When a perforated inner liner is specified, a retaining fabric must be wrapped, between the perforated inner and the glass fiber insulation.
Double Wall Grease Duct
We fabricate double wall duct in round, rectangular and flat oval. The pressure shell is fabricated according to our duct construction standards for gauge and reinforcing. Our standard for constructing double wall duct is to sandwich the insulation in between the outer wall, or pressure shell, and the inner lining of solid or perforated metal.

Double Wall Grease Duct
REDUCED AIR LEAKAGE One issue that rectangular ducts run into is air leakage. With an ovular shape and a double wall, air leakage is reduced virtually to zero in double wall oval ducts. This not only ensures more consistent air temperature, but it also ensures more efficient air delivery throughout your building.
