Knauf KoolDuct

Knauf Kool Duct Gives Real Energy Savings

Emphasis is on high performance with the Knauf KoolDuct System: Knauf Insulation presents a revolutionary approach to HVAC ductwork - The Knauf KoolDuct System. This system is a high performance, pre-insulated air ducting system specifically designed for the demanding requirements of the commercial and light industrial sectors. It offers many competitive advantages over conventional sheet metal ductwork systems including 10-20% total installed cost savings, depending on the project. The Knauf KoolDuct System resolves many common design issues such as weight, space, installation time and energy performance.

Complete System Technology: :/b> Why is the KoolDuct System a revolutionary approach? It's a comprehensive system. Along with the materials necessary to build high-specification ductwork, the system includes all the custom tools and machinery to efficiently fabricate every job and the specialized training to ensure our rigorous quality standards are maintained. Specifying the Knauf KoolDuct System assures a premium ductwork installation built with high quality materials-every time. And it's a proven system, used on high-profile projects worldwide for over three decades.



DESCRIPTION

The Knauf KoolDuct® System is a pre-insulated, high performance air duct system for industrial and high-end commercial applications. The system uses a CFC-free phenolic foam board faced on both sides with reinforced foil. Patented, specially engineered, aluminum flanges are designed to connect the duct sections to assure a strong, tight closure.

APPLICATION

The Knauf KoolDuct System is used in commercial, residential and industrial applications. The ducting is versatile and can be installed internally or externally, and concealed above a false ceiling or visibly mounted. It is easily modified and repaired and can be fabricated on-site with non-powered tools.
