Thermax™ Metal Building Board NH provides both insulation value and an interior finish system for walls in metal buildings. It consists of a polyisocyanurate foam core with 1.25-mil embossed aluminum facers on both sides. Thermax™ Metal Building Board NH offers high, long-term thermal resistance, with dual 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™ Metal Building Board NH – with its low perm rating – can help to reduce moisture condensation within and behind the insulation.
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.
