Graphite EPS Product with Enhanced R-Value

DuraLyte gray polystyrene (GPS) is built to last. With an increased thermal resistance (R-value), construction applications built with DuraLyte maintain their insulative properties for at least 50 years.

Not only does DuraLyte have a higher R-value, but its gray color does not show dirt like traditional EPS.
