1Conditioned thermal values were determined by ASTM Test Method C 518 at 75° mean temperature. Test specimens were conditioned in accordance with procedures outlined in ASTM C1289, Section 11.1.2.1.
2“R” means resistance to heat flow. The higher the R-value, the greater the insulating power.

Provides continuous insulation for exterior above- and below-grade walls for Type I-V construction.

  • Below grade exterior foundation walls
  • Under slab foundation
  • Available scored at 16ʺ and 24ʺ o.c.
  • Exterior framed walls with wood or steel studs
  • Exterior walls of masonry or concrete
