Thermax™ Light Duty
DuPont™ Thermax™ Light Duty Insulation is an easy-to-install, easy-to-clean insulation and interior finish system for walls and ceilings in metal, wood post frame and concrete or masonry buildings, as governed by building codes. It consists of a glass-fiber-reinforced polyisocyanurate foam core faced with nominal 1.25-mil embossed white thermoset-coated aluminum on one side and 1.25-mil embossed aluminum on the other. The tough white embossed aluminum surface makes it a durable insulation/finish choice for use in moderate-impact areas, and it can be pressure-washed at up to 2,000 psi with a 15-degree or greater spray tip (at 3’ minimum distance).
DuPont™ Thermax™ Brand insulation delivers wall performance you can count on. It’s ready to meet your toughest building challenges – both outside and inside the wall – with a robust ISO insulation product line and an R-value that’s proven consistent over time and a range of temperatures.
