Continuous Insulation is a relatively inexpensive and practical building component that boasts many benefits.
Explore the common nailing patterns for fastening non-structural Halo Exterra panels to these different substrate types. Read on to learn more!
To take advantage of Exterra’s breathability, you’ll need that poly vapor barrier on the warm side to block vapor and moisture from traveling inside the building. Learn more about this code requirement here.
Exterra provides an effective air control layer by default, so technically speaking, you don’t need any additional house wrap. So, regardless of the method you go with, you’ll have that integral air barrier in your wall.
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.
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.
If the existing walls do not have a layer of structural sheathing, they may require bracing per local building codes. If corner bracing is used, you will need to take steps to ensure all Exterra panels are flush with those Exterra panels installed at the corners.
What is the difference between Halo Exterra and ZIP Sheathing? Halo Exterra are rigid foam board insulation panels that feature a graphite polystyrene (GPS) foam core that is laminated on both sides with a layer of perforated polypropylene film. Halo Exterra panels marry a water-resistive barrier (WRB) to continuous exterior insulation, eliminating thermal bridging as […]
