23.06.01  |  Development of the ICC 1125 Standard for Classification of Magnesium Oxide Boards and Construction

The Code Council is developing this new standard to be referenced in the I-Codes. In response to feedback from industry, the Code Council identified that a North American product standard for building and construction uses of Magnesium Oxide (MgO) boards does not exist, and the product is viewed as unique to each manufacturer.  MgO board usage in North American construction is growing, and an industry standard to establish minimally acceptable performance levels to ensure proper MgO board performance in buildings is needed.
