Dual-TechTM Description

Shop-fabricated Dual-Tech is shipped to the site up to 8 feet long and ready to install.
PTM Dual-Tech is available in a variety of colored finishes.
The pre-insulated Dual-Tech system facilitiates a one-trade installation that speeds up install time.

PTM Dual-Tech combines the features and benefits of Kingspan's KoolDuct® with Techna-Duc in an all-in-one air distribution system.

Dual-Tech is a pre-fabricated, double-layer ducting system that is suitable for indoor and outdoor applications.  Its .032 embossed aluminum jacketing protects the Kingspan KoolDuct pre-insulated ductwork that is UL 181 listed as a Class 1 Air Duct system.  It is CFC/HCFC-free, using a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

The Dual-Tech system eliminates the need to install insulation as a second operation; this faster, single-install process reduces time onsite and improves overall construction schedules.

PTM Dual-Tech improves energy efficiency with its R-14 to R-16 insulation rating.  And it’s backed by PTM’s 10 year limited warranty.


Recommended Uses

PTM Dual-Tech is primarily designed for exterior HVAC ducting applications on new construction and existing HVAC upgrades. It delivers a maximum Static Pressure of positive 4 in. w.g./1000Pa and negative 3 in. w.g./750Pa. that will easily achieve SMACNA air leakage Class 3.  PTM Dual-Tech is suitable for interior applications as well. It is ideal for exposed ducting in mechanical equipment rooms, gymnasiums or anywhere a protection jacketed duct is needed. PTM Dual-Tech is the perfect choice for all HVAC supply, return, exhaust, fresh air, and outside air ducting needs, providing long-term energy efficiencies that will improve the IAQ of the building.
