A non-halogen insulation, designed for long-term thermal resistance in interior applications
Equipped with a glass-fiber reinforced polyisocyanurate foam core, DuPont™ Thermax™ Light Duty NH Insulation combines long-term thermal resistance with a durable, aesthestic white thermoset-coated aluminum facing. Thermax™ Light Duty NH uses halogen-free flame retardants and is manufactured with zero ozone-depleting potential.
Thermax™ Light Duty NH
DuPont™ Thermax™ Light Duty NH Insulation is an easy-to-install, easy-to-clean insulation and interior finish system for walls and ceilings in metal, concrete or masonry buildings. It consists of a glassfiber-reinforced polyisocyanurate foam core faced with a 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 1,000 psi with a 15-degree or greater spray tip (at minimum 3’ 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 polyiso insulation product line and an R-Value that’s proven to be consistent over time and a range of temperatures.
Available Sizes
Standard Thermax™ insulation board dimensions are 4'x8'. Custom lengths are available up to 30'. Please contact your local DuPont representative for additional availability details or call our product support team at 1-833-338-7668
