TUFF-R™ Commercial Insulation features a patented high-performance polyisocyanurate foam core with reflective foil facers on both sides, providing additional durability.
TUFF-R™ Commercial Insulation is used in commercial construction behind a minimum 1/2" gypsum board or equivalent thermal barrier interior finish.
Building Code Compliance
Complies with ASTM C1289 Type I. Meets IBC/IRC requirements for foam plastic insulation. See ICC-ES ESR-3089. Calif. Std. Reg. # CA T383. FM specification tested.
TUFF-R™ Commercial Insulation features reflective foil facers for enhanced thermal performance, moisture resistance and durability in commercial building applications.
|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) 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.
