Phenolic Interior Ductwork
The Kingspan KoolDuct® System, distributed by PTM Manufacturing, is a pre-insulated, high-performance phenolic air duct system designed for commercial, industrial, and residential applications. Constructed from a CFC/HCFC-free phenolic foam board with reinforced aluminum foil facings on both sides, KoolDuct® delivers exceptional thermal performance with R-6 at 7/8" thickness, R-8 at 1 ³⁄₁₆" thickness and R-12 at 1 ¾" thickness. The air stream flows only across smooth aluminum surfaces, providing a non-fibrous, clean, and hygienic solution ideal for sensitive environments. Fully SMACNA Phenolic Duct Construction Standards compliant, KoolDuct® meets UL 181 and ASTM-E-84 Smoke and Flame ratings for safe use in the U.S. and Canada, and its antimicrobial silicone helps prevent mold and mildew growth.
The One-Trade Solution
KoolDuct® simplifies coordination and installation through its single-trade installation process, eliminating the need for separate duct and insulation crews. Each duct section is fully assembled and factory sealed, with engineered, patented flanging systems ensuring strong, tight connections and long-term system integrity. The system easily integrates with fire dampers, VCDs, attenuators, and conventional sheet metal ductwork, providing flexibility without added complexity. PTM ensures consistent quality by supplying all fabrication materials and requiring that certified contractors complete specialized training, ensuring each project meets the highest performance and quality standards. With KoolDuct®, you get faster installation, consistent results, and measurable energy savings—all from one trade.
Saving Space, Weight & Time
The Kingspan KoolDuct® System offers significant advantages over traditional insulated sheet metal ductwork. KoolDuct® is up to 85% lighter, thinner, and requires roughly half the hangers and joints compared to conventional systems—resulting in faster installation and reduced labor costs. The virtually airtight, leak-free jointing system minimizes air leakage and improves energy performance, while the superior insulation properties of the phenolic panel reduce HVAC runtime and lower heating and cooling loads. These benefits collectively compress construction timelines, reduce installed costs, and improve building energy efficiency—making KoolDuct® the smart choice for modern, high-performance HVAC design.

The Icehouse Case Study
Read about how PTM Manufacturing contributed to Philadelphia's first LEED certified Multi-Family Low-Rise Complex and how it paved the way for a more sustainable outlook on future projects. The Icehouse is a three-story complex of 36 condominiums focused on energy efficiency, green attributes & sustainability. Partnering with the contractor, owners, and the design team, PTM provided the KoolDuct® that assisted this project in reaching its goal and delivering exceptional results.
Luther Homes Case Study
When it comes to designing energy-efficient buildings, even small choices in HVAC ductwork can have a huge impact. This case study explores a rare, side-by-side comparison of two nearly identical residential cottages at Luther Home of Mercy, each outfitted with a different air distribution system: one using The Kingspan KoolDuct® System, the other traditional sheet metal ducts insulated with glass fiber wrap. The results are striking; differences in air leakage, energy consumption, carbon emissions, and long-term costs reveal the true potential of modern ductwork solutions. Beyond the numbers, this study highlights how smart material selection can drive sustainability, reduce operational costs, and support ambitious carbon reduction goals, making it essential reading for anyone designing buildings for the future.
