DuPont™ Thermax™ Light Duty Insulation* is designed as an insulation and interior finish system for walls and ceilings in metal, wood post frame and concrete or masonry buildings, as governed by building codes. Thermax™ Light Duty 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 1.25 mil white embossed aluminum surface makes it a durable insulation/finish choice for use in moderate-impact areas, and it can be pressure-washed up to 2,000 psi with a 15-degree or greater spray tip (at 3’ minimum distance). Thermax™ Light Duty meets the USDA requirements for “Incidental Food Contact Materials” when used as surfaces not in direct contact with food, such as floors, walls, ceilings etc.)
Thermax™ Light Duty also offers high, long-term thermal resistance, with facers that help prevent water and water vapor intrusion into the insulation foam allowing it to stabilize at a higher R-value*. Used in conjunction with the appropriate joint closure system for the application, Thermax™ Light Duty – with its low perm rating – can help to reduce moisture condensation within and behind the insulation.
