DuPont™ Thermax™ Light Duty NH Insulation
Non-Halogenated (NH), Durable, Glass-Fiber-Reinforced Insulation with Aluminum Facers
DuPont™ Thermax™ Light Duty NH Insulation
Non-Halogenated (NH), Durable, Glass-Fiber-Reinforced Insulation with Aluminum Facers
<br><b>DuPont™ Thermax™ Light Duty NH Polyisocyanurate Insulation</b> 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. <br><br> <b>Thermax™ Light Duty NH Insulation</b> features a glass-fiber-reinforced polyiso foam core with 1.25 mil embossed white thermoset-coated aluminum on one side and 1.25 mil embossed aluminum on the other. This durable insulation is ideal for moderate-impact areas and can be pressure-washed up to 1,000 psi with a 15-degree or greater spray tip at a minimum distance of 3 feet. It meets USDA requirements for incidental food contact materials, making it suitable for surfaces like floors, walls, and ceilings. <br><br> Additionally,<b> Thermax™ Light Duty NH Insulation</b> offers high, long-term thermal resistance. Its facers prevent water and vapor intrusion, stabilizing the insulation at a higher R-value. When used with the appropriate joint closure system, its low perm rating helps reduce moisture condensation within and behind the insulation.

FAQ
Is there a paint color formulation to match DuPont™ Thermax™ Brand Insulation white acrylic-embossed insulation boards (DuPont™ Thermax™ White Finish NH Insulation, DuPont™ Thermax™ Light Duty NH Insulation and DuPont™ Thermax™ Heavy Duty Insulation)? Yes. Customers from anywhere in the United States can obtain the paint color match for Thermax™ white acrylic-embossed insulation boards at any Sherwin-Williams paint store nationwide. No primer is required, and usually one coat will be sufficient; however, two coats also appear satisfactory. Apply the paint with brush, roller or spray.

Can DuPont™ Thermax™ Brand Insulation be left exposed to the building interior? Thermax™ Brand Insulation products can be left exposed to the building interior (i.e., without a thermal barrier such as 1/2 inch gypsum wallboard) in specific non-rated ceiling assemblies or non-rated construction in commercial, industrial and agricultural buildings. Thermax™ Brand Insulation products cannot be left exposed to exterior conditions.
The use of Thermax™ Brand Insulation exposed to the building interior is documented with a Code Compliance Research Report (CCRR-0440).
NOTE: Thermax™ cannot be used as a duct work or plenum insulation- it does not meet the IBC /IMC for flame spread of 25 or less and smoke developed of 50 or less
Can DuPont™ Thermax™ Light Duty NH Insulation be washed with a spray/power washer? Yes. The following table outlines the conditions under which these Thermax™ Brand products can be power washed.
How much does DuPont™ Thermax™ Light Duty NH Insulation weigh? 0.197 lb/ft2
To get weight of 1 inch x 4 feet x 8 feet board multiple the value by 32
Example: Thermax™ Light Duty NH Insulation 1in x 4ft x 8ft weighs (0.197 x 32) = 6.3 lbs What are the ASTM C1289 classifications for DuPont polyisocyanurate products ? The ASTM C1289 classifications for DuPontpolyisocyanurate products are as shown below:
Type1 - Faced with aluminum foil on both major surfaces of the core foam. Class 1 - Non-reinforced core foam. Class 2 - Glass fiber reinforced core foam. Dimensional stability will be greater than Class 1 when fastened properly. ASTM C1289 Class 2 exceeds Class 1 requirements.
