R-values for rigid insulation vary from R-3.85 to R-6.8 per inch of thickness. Polyiso has the highest R-value, followed by XPS and EPS. The key to all rigid insulation high R-values are small air pockets that exhibit high thermal resistivity properties: Small air pockets visible in Styrofoam.
Insulation R-Values & RSI-Values of Materials - InspectAPedia
Additional R-value for a masonry wall constructed using these materials needs to add the insulating value of additional wall components typically included, such as 1" solid foam (polyisocyanurate R 8, extruded polystyrene R 5, expanded polystyrene R 4, …
LONG TERM INSULATION VALUE R-value means the resistance to heat flow. The higher the R-value the greater the resistance to heat flow. The thermal perfor-mance of EPS insulation, as with any insulation product, depends upon the correct installation using good building practice. When properly installed, the R-value of EPS insulation remains constant
StyrofoamTM Brand SM Insulation’s closed-cell structure resists water absorption, enabling it to retain a high R-value (RSI)** over time – a necessary property in below-grade residential foundation applications. It helps to protect foundation damp-proofing and waterproofing, especially during backfilling.
