Ideal for metal structures, Thermax? Metal Building Board NH delivers long-term R-value and is listed in 1-, 2-, 3- and 4-hour UL fire rated wall assemblies. Thermax? Metal Building Board NH uses halogen-free flame retardants and is manufactured with zero ozone-depleting potential.
Thermax? Metal Building Board NH
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 ¨C with its low perm rating ¨C can help to reduce moisture condensation within and behind the insulation.
k8ÓéÀÖ? Thermax? Brand insulation delivers wall performance you can count on. It¡¯s ready to meet your toughest building challenges ¨C both outside and inside the wall ¨C with a robust polyiso insulation product line and an R-Value that¡¯s proven consistent over time and a range of temperatures.
