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.
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.
Halo Exterra is not structural – it does not contribute structural strength to a home or building. However, despite not being structural, Halo Exterra can replace OSB sheathing if structural bracing is provided at the corners and certain sections of the wall to provide the needed resistance to wind and seismic loads.
When choosing an acceptable adhesive for your foam board insulation, you should use a weather-resistant construction glue that is compatible with expanded polystyrene foam to secure Halo products to wood or concrete surfaces. Discover two great options here.
To help protect against termites in high infestation areas (which are generally concentrated in the South east USA) Halo Subterra and Exterra products are available from our plants in Tennessee, Mississippi and Kansas with foam cores treated with Preventol, which adds an secondary layer of defense against termites.
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.
Is Graphite Polystyrene (GPS) An Open Or Closed Cell Insulation? (And Why It Matters!) Insulation can be referred to as either open or closed cell
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.
Halo Subterra is a below-ground rigid insulation that is offered at a variety of compressive strengths, starting at 16 psi.
