Overview

GenFlex HD Comp consists of a 1/2” GenFlex HD ISO laminated directly to GenFlex GL ISO. By combining these two proven products in an in-line manufacturing process, the building owner receives a high-performing, energy-efficient insulation board, while the installer saves time and labor due to not having to adhere another layer.

 

In addition, since GenFlex HD ISO is made in a controlled environment, the risk of other variables that can impact the performance of the product be it dirt, adhesive application, etc. are greatly reduced.
