Lightweight, One-Trade Installation
Dual-Tech® revolutionizes HVAC ducting with a fully prefabricated, lightweight, double-layer construction that allows for true single-trade installation. Built from SMACNA-compliant Kingspan KoolDuct® panels and encased in a .032" aluminum Kynar jacket that holds a 30-year warranty, Dual-Tech® eliminates the need for a separate insulation process saving significant time, labor, and coordination on-site. Each system arrives factory-assembled and fully sealed, ensuring airtight performance right out of the crate.
At less than 2 lbs. per square foot, Dual-Tech® weighs approximately one-third the weight of traditional sheet metal and insulation, easing handling and reducing roof load demands while maintaining exceptional structural integrity. This pre-insulated design enables installation speeds up to twice as fast as conventional systems and eliminates oversizing at T.D.C. joints since the insulation is integrated into the duct wall itself. The result is a clean, streamlined installation process that minimizes disruption, shortens construction timelines, and consistently delivers measurable cost savings
Coverage for a Lifetime
Engineered for long-term performance, PTM’s Dual-Tech® carries a 20-year limited warranty; a reflection of its proven reliability and superior construction. The system’s patented interlocking joints and vapor-tight seals achieve less than 1% air leakage, far exceeding SMACNA Class 3 standards. With thermal ratings of R-12 or R-16 (higher values available), Dual-Tech® dramatically reduces HVAC system runtime and operating costs, improving overall energy performance and extending system life.
Its inner layer is UL-181 Listed as a Class 1 Air Duct system, ensuring compliance with stringent air distribution and fire-safety standards. The rigid phenolic insulation core resists moisture, mold, and mildew, maintaining consistent performance in all weather conditions and eliminating the maintenance concerns typical of traditional ductwork systems. Over its 20-year life,
Dual-Tech® delivers whole-life cost savings of up to 30%, lowering both energy consumption and long-term service expenses while providing the confidence of guaranteed durability.
All-in-One Duct System
Dual-Tech® combines the high-efficiency phenolic technology of Kingspan KoolDuct® with the durable exterior protection of Techna-Duc®, creating an all-in-one, pre-insulated ducting solution for interior and exterior applications. Its environmentally responsible design uses a CFC/HCFC-free blowing agent with zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP), contributing to a lower carbon footprint and a cleaner built environment. The smooth aluminum air stream eliminates fibrous materials from the airflow, making Dual-Tech® ideal for facilities with stringent indoor air quality or hygiene requirements such as healthcare, education, and clean manufacturing environments.
With airtight, factory-sealed seams, superior thermal performance, and long-term resistance to weather and wear, Dual-Tech® represents the next generation of HVAC air distribution, lightweight, energy-efficient, sustainable, and built to last. Ductwork fabricated from this system can even contribute to LEED credits under the U.S. Green Building Council’s rating system, supporting sustainable design goals while improving indoor air quality and energy efficiency. Wherever performance, reliability, and environmental responsibility are priorities, Dual-Tech® delivers unmatched results for the lifetime of the building.

Single-Layer
Through a meticulous process of assembling, sealing, and weatherproofing a base product of the Kingspan KoolDuct® system, PTM Manufacturing, LLC creates a durable and simple exterior ductwork system. Following SMACNA construction of the KoolDuct® ductwork, a jacket system of .032” aluminum (multiple finishes & colors available) is applied in such a way to shed water at all seams. The airstream ductwork is fabricated from Kingspan KoolDuct® panels that are UL listed as a Class 1 Air Duct System meeting the standard UL 181. CFC/HCFC-free, using a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP). PTM’s Single Layer Dual-Tech® Ductwork System has a single-trade install application; eliminating the need to install insulation as a second operation, thus reducing time onsite and improving overall construction schedules through even faster installation speeds. Once installed, our ductwork solution improves energy efficiency and is built to last.
Double-Layer
PTM's Double-Layer Dual-Tech® is a prefabricated ductwork system with an 0.32" aluminum jacket(multiple finishes & colors available) that uses KingSpan KoolDuct® Panels that are UL Listed as a Class 1 Air Duct System meeting the standard UL 181 CFC/HCFC-free, using a blowing agent that has zero Ozone Depletion Potential(ODP) and low Global Warming Potential(GWP). PTM Dual-Tech® has a single install application; eliminating the need to install insulation as a second operation, thus reducing time onsite and improving overall construction schedules through faster installation speeds. PTM Dual-Tech® improves energy efficiency and is backed by a PTM 20-year limited warranty. PTM Dual-Tech® is the perfect choice for all HVAC Supply, Return, Exhaust, Fresh Air, and Outside Air ductwork needs, providing long-term energy efficiencies that will also improve the IAQ of the building.
