PlastiSpan® 25 Insulation
Increased R-value & compressive resistance
• Meets all building code requirements
• Meets ASTM C578, Type IX
• Thermal resistance - R-value 4.4 per inch
• Closed cell insulation resists moisture
EPS is closed cell, rigid foam plastic insulation that does not contain a
blowing agent that provides temporary increase in thermal resistance.
PlastiSpan insulation applied to continuous insulation over foundations,
walls and roofs eliminates thermal bridging, increasing your total effective
R-value. This reduces energy costs and increases your energy savings.
PlastiSpan expanded polystyrene (EPS) insulation conforms to ASTM C578,
Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation, as
detailed below. PlastiSpan insulation has also been evaluated for
conformance with the requirements of ICC-ES AC12, Acceptance Criteria for
Foam Plastic Insulation per ICC-ES Evaluation Report ESR-1587 and
Intertek Code Compliance Research Report CCRR-1072 (see Code Support
section in Technical Library for additional information).
