Distribution, technical support, and application expertise for commercial phenolic duct systems
Thermatuff® is an engineered phenolic insulation panel developed for commercial HVAC insulated ductwork and duct liner applications. The panel can be fabricated into a complete pre-insulated duct system that combines duct construction and thermal insulation in one assembly, or mechanically retained inside sheet metal ductwork as a durable phenolic duct liner. Thermatuff® gives contractors, fabricators, and engineers a versatile alternative for projects requiring high-performance insulated ductwork.
How You Can Find Savings With the Thermaduct® Thermatuff® System
Thermatuff® is available in R-6, R-8, and R-12 insulation values to meet the requirements of demanding commercial HVAC systems. When used as pre-insulated ductwork, the 2-in-1 system can reduce the need for separate field-applied insulation and help simplify fabrication, installation, and project coordination. When used as a sheet metal duct liner, Thermatuff® provides a smooth, non-fibrous insulation surface that can be mechanically retained without relying on adhesive installation. Building owners, fabrication shops, and installing contractors can benefit from reduced installation steps, dependable thermal performance, and greater flexibility across both new construction and retrofit projects.
Lightweight
Thermatuff® pre-insulated duct systems are significantly lighter than comparable insulated sheet metal assemblies, making duct sections easier to transport, lift, position, and install. Reduced weight can help crews work more efficiently while placing less load on supports and surrounding building structures.
Efficient Installation
Thermatuff® can be fabricated in sections up to 13 feet and require fewer hangers than traditional metal ductwork. This alone can offer significant savings over the course of an application. Larger fabricated sections and system-specific support requirements can help contractors install more ductwork with less handling and improved schedule control.
Pre-Insulated
With Thermatuff®, there’s no need to insulate your ductwork after. Our rigid insulated panels come at a minimum R6 insulated value! Because of this, duct can be installed flush to the ceiling. This 2-in-1 approach can reduce trade coordination, simplify installation in congested areas, and provide consistent insulation coverage throughout the duct system.
No Duct Sealing
Thermatuff®'s installation process provides some of the lowest air leakage rates in the industry. An low leakage design means you won’t need to be sealing your ductwork after it is hung. Properly fabricated and installed systems can reduce the field sealing, testing corrections, and rework often associated with conventional duct construction.
