Halo Exterra

Halo Exterra is a rigid graphite polystyrene (GPS) insulation board designed for exterior above-grade wall assemblies. Its perforated laminate facing helps support outward drying, while the GPS core delivers continuous insulation and strong long-term thermal performance. Exterra is suited for residential, commercial, and industrial wall systems where energy efficiency and moisture management are both important.
