The maximum moisture content permitted for fire-retardant wood structural panels is set at 15%. This specification is crucial because elevated moisture levels can significantly reduce the effectiveness of fire-retardant treatments and compromise the structural integrity of the panels. The fire-retardant materials rely on certain chemical properties that are optimized at lower moisture levels. When moisture content exceeds this threshold, it can lead to diminished fire performance, longer drying times, and potential issues with mold or decay, which poses both a safety risk and affects the lifespan of the structural materials. This is why maintaining moisture levels within the specified range is essential in construction practices.
