(1) Not available in Wash., Ore., Mont., Wyo., Idaho, Calif., Nev., Utah or Ariz.

(2) 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. R-value determined by ASTM C518.

(3) Vertical compressive strength is measured at 10% deformation or at yield, whichever occurs first.
