Do you worry about exposing foam board insulation to the outdoors? Or leaving it uncovered inside a home? Read more to explore the perils of exterior and interior exposure, and how you can get the most of your foam board insulation.
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.
Discover how Halo is powered by Graphite Polystyrene (GPS) and the benefits of our Neopor core. GPS provides a long-term thermal performance of R5 per nominal inch (1.06″) while offering a minuscule embodied carbon footprint compared to XPS.
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 […]
WILL 2 LAYERS OF EXTERRA STILL BE PERMEABLE? No. Two layers of Exterra will not meet the minimum requirement of being “permeable”, which is 60 ng/Pa-s-m2, or 1 perm. A single layer of Exterra maintains it’s breathability up to a maximum thickness of 2” (71 ng/Pa-s-m2 or 1.2 perms at 2”). Exterra panels are laminated […]
