Fire safety is a critical consideration for any building, particularly when it comes to protecting essential electrical and mechanical systems. These systems are the backbone of a building’s operations, powering everything from lighting and ventilation to fire suppression systems.
Protecting them during a fire is crucial, not only to safeguard property but also to ensure the safety of occupants. Calcium silicate boards have emerged as a leading material for creating fire-rated E&M (Electrical and Mechanical) enclosure systems that shield these vital systems from heat, smoke, and toxic fumes.
Understanding E&M Enclosure Systems
An E&M enclosure system is a specially designed fire-rated structure that houses electrical and mechanical systems within a building. These enclosures prevent the spread of fire and smoke, maintaining the integrity of critical infrastructure such as power supply lines, ventilation ducts, and fire suppression mechanisms. In the event of a fire, a well-designed E&M enclosure allows essential systems to remain operational for a limited period—typically between 0.5 to 4 hours—enabling safe evacuation and minimizing damage.
E&M enclosures are not just about containing fire; they also maintain safe temperature levels and prevent heat from compromising sensitive equipment. Achieving this requires materials that are highly resistant to heat, dimensionally stable, and durable over time. Calcium silicate boards meet all these requirements, making them an essential component of any effective E&M enclosure.

Why Calcium Silicate Boards Are Ideal for E&M Enclosures
Fire-Resistant and Thermally Insulating
Calcium silicate boards are inherently non-combustible, making them a perfect choice for fire-rated enclosure systems. They act as a barrier against flames and smoke, helping to protect electrical and mechanical systems during critical moments. Their fire resistance can last several hours, depending on thickness and installation methods, providing a reliable safety buffer.
High Temperature Resistance
New Element’s calcium silicate boards are engineered to withstand extreme temperatures of up to 1200°C. This high-temperature tolerance ensures that systems housed within E&M enclosures remain protected even under severe fire conditions. The boards’ thermal stability also contributes to long-term durability, maintaining structural integrity in both industrial and commercial applications.

Low Thermal Conductivity
Thermal insulation is another key benefit of calcium silicate boards. Their low thermal conductivity minimizes heat transfer, helping to maintain safer temperatures inside the enclosure and reduce energy consumption for cooling. This makes them ideal for walls, ceilings, and floors in both residential and commercial buildings, improving comfort and energy efficiency.
Durability and Mothproof Performance
Durability is critical in environments exposed to heat, moisture, and mechanical stress. These fire-resistant calcium silicate boards are resistant to wear, impact, and pests, including moths, which can compromise the material over time. Their robust construction ensures long-term reliability, reducing maintenance costs and ensuring the enclosure continues to protect systems effectively.
Lightweight and Easy to Work With
Ease of installation is a practical advantage of thermal insulation calcium silicate boards. Their lightweight design simplifies handling, transport, and installation, while their manageable density allows for quick on-site cutting and customization. This reduces labor costs and installation time, making them a convenient choice for both small-scale and large-scale projects.
