SilveRboard® Graphite XS is an expanded polystyrene (EPS) base material that incorporates a carbon graphite coating which increases the thermal performance of the EPS insulation. The graphite EPS beads reflect radiant heat energy similar to the effect of a mirror and reduce thermal conductivity which increases the materials ability to resist the flow of heat or R value. SilveRboard® Graphite XS is a higher performing insulated exterior wall sheathing compared to Extruded Polystyrene (XPS).

SilveRboard Graphite XS is a combination of graphite coated EPS beads surrounded by air pockets, laminated on both sides with perforated reflective polystyrene film. Ninety-Eight percent of the EPS in SilveRboard Graphite XS is air, we call this insulation “Engineered Air”. This highly effective combination provides one of the most energy efficient, environmentally friendly, sustainable and cost effective insulation products available today. SilveRboard Graphite XS, performs better than traditional flat-sheet insulation by providing a built in vapour and Air Barrier plus the colder the climate the higher the thermal resistance or R value.
