Dual-TechTM Features and Benefits

  • Dual-Tech resolves issues that exist with many traditional sheet metal systems with insulation – such as weight, space, installation time, and energy performance.  

  • Dual-Tech is ideal for jobs where a non-fibrous solution is desired. The air stream in the sealed duct flows only on aluminum, making it ideally suited for high specification applications.

  • The patent-pending system combined with the fully sealed duct seams produce a system that is virtually airtight.  

  • Dual-Tech yields significant savings in reduced heating and cooling loads due to the superior insulating properties of the phenolic panel and minimal air leakage of the jointing system.

  • Dual-Tech offers significant installed cost savings over other insulated sheet metal systems.
