(1) 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. RSI values are expressed in m2 °C/W. R-value determined by ASTM C518.

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