Graphite Polystyrene Insulation: R-Value Performance for Building Envelopes
Rigid foam insulation has carried a growing share of the building envelope for decades, and graphite polystyrene is the latest step in that line. Graphite polystyrene is expanded polystyrene with microscopic graphite particles added during manufacturing. The particles absorb and re-emit radiant heat, which lets the board reach higher R-values at thinner profiles than conventional […]
