This work pertains to the ArmorWall™ Plus SIS system by DuPont Performance Building Solutions. I put this system through a series of rigorous simulations representing all climate zones and extreme ‘Year 1’ ASHRAE climate data.  My findings show an elegant system that retains a high level of adaptability while remaining profoundly simple. 

ABSTRACT – Moisture performance of Structural Insulated Sheathing (SIS) was simulated for 15 climate locations representing all North American climate zones. Analyses employed common wall types and a proprietary SIS panel integrating magnesium oxide as the sheathing component. Simulation outcomes revealed a highly effective and adaptable enclosure system. Its performance is linked to a complement of material properties offering high water resistance and exceptional vapor control.
