EPS frequently has a high recycled content. Its vapor permeability is higher and its R-value lower than XPS insulation. EPS insulation is classified by type: Type I is lowest in density and strength and Type X is highest. panels separated by 99% post-industrial recycled polypropylene plastic webbing on 8" centers. The webbing serves as strapping for attachment of interior and exterior finishes and as support for steel reinforcing rods within the wall. Each standard interlocking Arxx block is 4' long, 16-3/4" high, and 11-1/2" thick with a steady-state R-valueMeasure of resistance to heat flow; the higher the R-value, the lower the heat loss. The inverse of U-factor. of 22.1. Other thicknesses (4", 8", and 10") and configurations are available, as are a number of accessories that facilitate construction.
