PlastiSpan® 40 Insulation
High compressive resistance for geotechnical applications

PlastiSpan® 40 Insulation is used in Roadways, Sidewalks and Utilities.


PlastiSpan® 40 insulation is a moulded expanded polystyrene (EPS)
insulation.

• Meets all building code requirements
• Meets ASTM C578, Type XIV
• Thermal resistance - R-value 4.4 per inch
• Closed cell insulation resists moisture

EPS is a closed call, rigid foam plastic insulation that does not contain a
blowing agent that provides a temporary increase in thermal resistance.

PlastiSpan insulation applied a 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 Polystyne 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).

Sustainability

As part of its commitment to quality and ongoing sustainability initiatives, Plasti-Fab maintains GREENGUARD Gold
Certification
for PlastiSpan 40 insulation with UL Environment, an independent global safety science organization.
The GREENGUARD Gold Certification mark on PlastiSpan 40 insulation gives assurance that insulation designed for
use in indoor spaces meets strict chemical emissions limits, which contribute to the creation of healthier interiors.
