Double wall duct and fittings mcgill airflow s rectangular k27 duct and fittings provide exceptional noise and thermal control in air handling systems.

Double wall insulated rectangular ductwork.

This double wall insulated ductwork is constructed of a solid metal outer pressure shell and a metal inner liner with a layer of insulation sandwiched between. 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. When a perforated inner liner is specified a retaining fabric must be wrapped between the perforated inner and the glass fiber insulation. In double wall rectangular 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.

This provides some additional characteristic to the duct as well as allowing a few more insulation options. Double wall rectangular ducts utilize the same outer metal shell and insulation media as our internally lined rectangular ducts but have an additional metal inner shell between the insulation and the airstream. This double wall insulated ductwork is constructed of a solid metal outer pressure shell and a metal inner liner with a layer of insulation sandwiched between. The acoustical thermal insulation can be used with air velocities up to 10 000 fpm and temperatures up to 250 f.

Duct liner shall be of the specified materials thickness and density of the contractors request.
