How to Determine The Correct Foam Board Insulation Thickness For Your Project?

Foam board insulation is an essential component in any wall assembly — it boosts R-values, helps manage moisture build up in the wall cavity and eliminates thermal bridging. But how thick should your layer of rigid insulation be? The answer hinges on nine general factors that determine the required thickness of foam board insulation on […]

How Does GPS Perform Compared to XPS and Poly ISO?

Halo Exterra foam board

What Is GPS? Graphite Polystyrene (GPS) is a type of polystyrene foam insulation and is the insulation material that forms the core of Halo’s Interra®, Exterra®, and Subterra® panels. GPS is basically Expanded Polystyrene (EPS) which is infused with graphite particles. These graphite particles reflect radiant heat as it moves through the insulation, thus slowing down heat transfer considerably. […]

Is Graphite Polystyrene (GPS) An Open Or Closed Cell Insulation? (And Why It Matters!)

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 […]

Halo’s Type 1 GPS Still Outperforms!

Neopor being cut

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.

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.

What is Graphite Foam Insulation?

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.

XPS HFC Bans Won’t Matter When You Use Halo

Halo GPS Insulated Home

The entire US is on track to re-join the Paris Agreement and gradually ban HFCs. XPS is not the only high-performance product on the market, and with high, long-lasting R-values and a 0-HFC content, Halo’s GPS is already a better, cleaner alternative.

How Do You Protect Foam Board Insulation From Termites and Ants?

HOW DO YOU PROTECT FOAM BOARD INSULATION FROM TERMITES AND ANTS? For above-grade applications, it is best to protect Halo Exterra foam board insulation from termites and ants by using bug screens. For Below grade applications, Halo Subterra foam board can be purchased from participating plants with a termite-resistant additive. Termite Area Map Exterra is the Halo foam […]
