See how Halo’s GPS core still surpasses the new Foamular 150 NGX. The NEW and improved XPS still uses more energy and resources than Halo’s Type 1 GPS and creates a foam board product that offers lower long-term 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.

Halo’s rigid insulation system relies on an advanced graphite foam core that outperforms its leading XPS contenders in efficiency and low emissions. Halo’s products — Interra, Exterra, and Subterra — are each tailored to a specific application.

We’re committed to equipping you with all the right tools and information before you build with Halo. These installation guides, as well as our interactive webcasts, should help you kick off your next project.

Halo Subterra is a below-ground rigid insulation that is offered at a variety of compressive strengths, starting at 16 psi.

Adding Continuous Insulation, such as Halo’s Exterra, to your wall assembly can simplify your path to code compliance. Apart from helping you keep up with the evolving energy code regulations, designing walls with CI like Exterra can also lessen the load on your conditioning systems and save valuable resources.
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.

With Halo® Exterra® rigid insulation, Structural wood sheathing and Zip System Sheathing are both compliant bracing methods that integrate perfectly into the building’s envelope.
