DuPont™ Thermax™ White Finish NH Insulation
Non-Halogenated (NH), Embossed White Acrylic Coated, Glass-Fiber Reinforced Polyiso Foam Insulation
DuPont™ Thermax™ White Finish NH Insulation
Non-Halogenated (NH), Embossed White Acrylic Coated, Glass-Fiber Reinforced Polyiso Foam Insulation
<br><b>DuPont™ Thermax™ White Finish NH Polyisocyanurate Insulation</b> is designed for use as both an insulation and interior finish system. It is suitable for interior masonry or concrete walls, as well as walls and ceilings in metal, wood post frame, and concrete or masonry buildings, adhering to building code requirements.
<br><br>
<b>Thermax™ White Finish NH Insulation</b> features a glass-fiber-reinforced polyisocyanurate foam core, with one side faced with 1.25 mil embossed white acrylic-coated aluminum and the other with 0.9 mil smooth aluminum. The white embossed surface is aesthetically pleasing and easy to clean, capable of withstanding pressure washing up to 1,000 psi. It also meets USDA requirements for incidental food contact when used on surfaces like floors, walls, and ceilings.
<br><br>
Thermax™ Brand Insulations are manufactured using an exclusive free-rise process, resulting in a closed-cell foam with enhanced fire performance. This foam core, combined with durable facers, provides high R-value, excellent dimensional stability, and moisture resistance. When paired with the appropriate joint closure system, <b>Thermax™ White Finish NH Insulation's</b> low perm rating effectively prevents moisture condensation within and behind the insulation.
