Graphite polystyrene (GPS) rigid board insulation with double-sided reflective film that improves thermal comfort and energy efficiency.
High performing and cost effective non-structural graphite polystyrene (GPS) rigid insulation board for exterior wall applications on wood or steel frame construction. The expanded polystyrene (EPS) core is embedded with graphite particles which increase the thermal performance, compared to conventional EPS.
In addition to the increased thermal resistance, the foam is laminated with a reflective film on both sides increasing board strength and flexibility, reducing site damage and waste. The reflective laminated surfaces are micro perforated giving the panel high water vapor permeance greatly reducing the likelihood of trapped moisture through the increased drying potential. The larger panels and laminated film help improve job site efficiency and reduce labor costs.
