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 insulation. Cell structures of closed-cell insulation are completely closed. Whereas open-cell insulation is made up of cells that aren’t completely closed – cell walls are open or shared. Both 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.
Halo Subterra is a below-ground rigid insulation that is offered at a variety of compressive strengths, starting at 16 psi.
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.
Is Halo Insulation an Air Barrier? Halo Interra Series Can Function as an Air Barrier, While Halo Exterra Cannot. An air barrier is a component of the building envelope system that blocks air movement between a conditioned and an unconditioned space. As its primary goal is to stop drafts and leaks, an air barrier must […]
Can Foam Board Insulation Be Used Between Studs Instead of Batt Insulation? This application is not typically recommended for the following reasons: Rigid foam board pieces are difficult to fit snugly between studs so you would have to spray foam to fill any gaps. Unlike loose-fill or batt, foam board insulation can’t easily be cut […]
