Thermax™ Metal Building Board
Thermax™ Metal Building Board* provides both insulation value and an interior finish system for walls in metal buildings as well as in standing seam metal roofs. It consists of a polyisocyanurate foam core with 1.25 mil embossed aluminum facers on both sides and a Sound Transmission Classification (STC) of 15. Thermax™ Metal Building Board offers high, long-term thermal resistance, with 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 – with its low perm rating – can help to reduce moisture condensation within and behind the insulation
