An E&M (Electrical and Mechanical) enclosure system is a fire-rated structure designed to protect essential mechanical and electrical systems and services within a building, preventing fire, smoke, and toxic fumes from spreading. These enclosures are crucial for maintaining the functionality of critical systems like power, ventilation, and fire suppression during a fire, allowing for safe evacuation and minimizing damage.

And our calcium silicate board is one of the important part of the E&M (Electrical and Mechanical) enclosure system, which is won't burn, protecting the essential mechanical and electrical systems for 0.5-4 hours.
