How Does GPS Perform Compared to XPS and Poly ISO?
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. […]
Halo’s Type 1 GPS Still Outperforms!
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.
