THERMAX White Finish (WF) polyisocyanurate insulation is designed as an insulation and interior finish system for interior masonry or concrete walls, plus walls and ceilings in metal, wood post frame, and concrete or masonry buildings, as governed by building codes. The glass-fiber-reinforced polyisocyanurate foam core of THERMAX White Finish is faced with nominal 1.25 mil embossed white acrylic coated aluminum on one side and 0.9 mil smooth aluminum on the other. The white embossed surface of THERMAX™ White Finish is aesthetically pleasing and easy to clean. It can be pressure-washed up to 1,000 psi with a 15-degree or greater spray tip (at minimum 3' distance).
THERMAX White Finish insulation can be installed exposed to the interior without a thermal barrier.

Building Code Compliance
Complies with ASTM C 1289 Type I, Class 2. Meets IBC/IRC requirements for foam plastic insulation. See NES NER 681.
**Not all product sizes are available in all regions.
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.
Vertical compressive strength is measured at 10% deformation or at yield, whichever occurs first.
1 R-value determined by ASTM C518.
