WebMay 8, 2024 · This is a code requirement for all insulation systems used on rooftop ducts 2. Beyond the closed-cell nature of poly-iso foam, it is also light weight and offers high compressive strength when compared to fiberglass (poly-iso >16 psi vs. fiberglass <1 psi). This can make it much easier to utilize and fabricate on a rooftop, and its compressive ... WebExtruded polystyrene (XPS) has a higher initial thermal resistance per inch compared to EPS, but this resistance degrades over time as the blowing agents in XPS escape. Recent industry research indicates the R-value of XPS is near 4.3 per inch after 50 years. EPS has a stable, long-term R-value that does not degrade over time and provides ...
