Why Adding a Layer of CI Is the More Cost-Effective Way to Increase Effective R-Value of Above-Grade Walls
Simply adding a layer of CI, such as Halo’s Exterra, can give you a whopping 34.5% R-Value boost, while only increasing your costs slightly. This method also creates a higher thermal lag, leading to reduced long-term energy costs.
What Is the Difference Between Halo Exterra and Comfortboard?
Halo Exterra performs two functions in a building enclosure assembly (thermal resistance + functions as the water control layer with sealed joints), whereas Comfortboard by Rockwool only performs a single function providing a somewhat lower thermal resistance.
