TUFF-R™ Commercial Insulation

Nominal Board Thickness(1), in R-Value(2) Board Size, ft Edge Treatment Min Compressive Strength(3), psi
1.0 6.5 4' x 8' / 4' x 9' Square Edge 25
1.50 9.8 4' x 8' / 4' x 9' Square Edge 25
2.0 13.0 4' x 8' / 4' x 9' Square Edge 25

(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 yield, whichever occurs first. Since Dow polyisocyanurate insulation is a visco-elastic material, adequate design safety factors should be used to prevent long-term creep. For static loads, 3:1 is suggested. For dynamic loads, 5:1 is suggested.
