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 insulated rectangular ductwork.

Pro fab sheet metal s double wall rectangular duct and fittings provide exceptional noise and thermal control in air handling systems. Duct liner shall be of the specified materials thickness and density of the contractors request. The acoustical thermal insulation can be used with air velocities up to 10 000 fpm and temperatures up to 250 f. When a perforated inner liner is specified a retaining fabric must be wrapped between the perforated inner and the glass fiber insulation.

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. 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.
