Thermax™ Basic NH
DuPont™ Thermax™ Basic NH Insulation is a non-structural, rigid board insulation consisting of a glass-fiber-infused, closed-cell polyisocyanurate foam core laminated between 1.0 mil smooth reflective aluminum facers on both sides. As a result, Thermax™ Basic NH offers high, long-term R-Value providing continuous, durable insulation within the building envelope.
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 consistent over time and a range of temperatures.
