The webinar, presented by Sterling Minter from Ducts and Cleats, focuses on the advantages of using Pro-R pre-insulated phenolic ductwork for exterior applications. The session emphasizes the superior performance, energy efficiency, and durability of Pro-R ductwork compared to traditional insulated metal duct systems.
Sterling begins by introducing Ducts and Cleats, a union sheet metal contractor based in St. Paul, Minnesota, specializing in fabricating custom ductwork, including the Pro-R pre-insulated phenolic duct. Pro-R is positioned as the premier phenolic duct system in the U.S., adhering to SMACNA standards and designed to offer long-term energy efficiency and durability.
A key focus of the presentation is the inherent issues with traditional insulated metal ductwork. Sterling explains that conventional duct systems have a high failure rate, often within a few years, due to moisture absorption in the open-cell fiberglass insulation commonly used. This leads to problems like mold, mildew, thermal bridging, and structural integrity loss. Traditional duct systems also suffer from significant air leakage, which reduces energy efficiency. According to SMACNA standards, insulated metal ducts are classified as Class 6 leak systems, meaning they leak 6% of the air per inch of static pressure for every 100 square feet of duct. This leakage not only wastes energy but also allows moisture to penetrate, further degrading the system.
In contrast, Pro-R duct, made from phenolic material, provides several advantages. The core material has a very low water absorption rate (0.14% after 24 hours), making it highly resistant to moisture. Pro-R also eliminates the need for field-applied insulation, reducing labor costs and installation errors. The system includes a double-layer construction with a phenolic core sandwiched between two layers of aluminum, providing superior insulation and durability. This design makes Pro-R ductwork a double-duct system with integrated flanges and gaskets that reduce air leakage to less than 1%, significantly improving energy efficiency.
Pro-R duct is particularly suitable for exterior installations, with a durable embossed aluminum jacket that is the same material used for metal roofs and comes with a 20-year warranty. The system is available in various colors and can be customized to meet specific project needs without impacting production timelines. The installation process is simplified, requiring minimal training and ensuring a tight, leak-free seal.
In conclusion, Pro-R duct offers a modern, efficient solution for exterior ductwork, outperforming traditional insulated metal duct systems in terms of energy savings, durability, and resistance to environmental factors. The webinar encourages contractors and engineers to consider Pro-R as their go-to solution for exterior duct applications, highlighting its long-term benefits in reducing air leakage, preventing moisture damage, and cutting energy costs.
