1PlastiSpan insulation is evaluated by the ICC-ES Evaluation Service under ESR-1587.
2Material properties meet or exceed requirements for ASTM C578, Type I and are third party certified under a quality listing program administered by Intertek Testing Services.
3Values are minimum per 1-inch (25.4-mm) of thickness at mean temperatures of 75 °F (24 °C) and 40 °F (4.4 °C).
4Values are maximum for 1-inch (25.4-mm) thick samples with natural skins intact. Lower values will result for thicker materials.
5ASTM C578 maximum water absorption is determined using ASTM Test Method C272.
