Building Code Compliance
Complies with ASTM C 578 Type IV. Meets IBC/IRC requirements for foam plastic insulation. See ICBO-ES ER 2257, BOCA-ES RR 21-02, NES NER 699, Und. Lab. Inc.® Classified, see Classification Certificate D369.
**Not all product sizes are available in all regions.
††Vertical compressive strength is measured at 10% deformation or at yield, whichever occurs first.
†R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2•h•°F/Btu.
