Fire Resistance of MgO Boards

Fire Resistance of MgO BoardsNon-Combustible Nature

You want your building to stay safe during a fire. MgO boards give you that safety because of their noncombustibility. When you use these boards, you choose a material that does not catch fire or help flames spread. Many scientific tests prove this. For example, the ASTM E84 test shows zero flame spread on MgO boards. The EN 13501-1 standard gives them an A1 non-combustible rating, which is the highest class for fire safety. You can see how MgO boards perform in the table below:

You get strong fire protection because MgO boards do not burn or add fuel to a fire. Their noncombustibility comes from their mineral makeup. You can trust them to keep your space safer than wood or drywall. A 2019 study found that MgO boards had lower insulation times than gypsum, but when you add steel sheathing, their fire resistance improves even more. Another study in the UK tested six samples and confirmed that most MgO boards meet the needed standards for thickness, density, and strength.

Note: MgO boards meet strict fire safety rules in many countries. They pass EN 13501-1 for Class A1 noncombustibility and follow Canadian standards like CAN/ULC S114 and ULC S135.

High Temperature Performance

You need a board that stands up to high heat. MgO boards do just that. They can withstand temperatures up to 800°C (1,472°F) without burning. Even at 1200°C, these boards stay flame-free. This means you get more time to escape or protect your property during a fire. MgO boards keep their shape and strength under extreme heat, so they do not break down or lose their fire resistance.

  • MgO boards do not burn, even in very hot fires.

  • They keep their structure and do not fall apart.

  • You get more time and better fire protection for your building.

This high level of noncombustibility makes MgO boards a top choice for places where fire risk is high. You can use them in kitchens, boiler rooms, or anywhere you need extra fire resistance.

Fire-Resistant MgO Boards vs. Gypsum Boards

You might wonder how fire-resistant MgO boards compare to gypsum boards. The difference is clear when you look at fire resistance and noncombustibility. MgO boards have a much higher fire rating and last longer in a fire. Here is a table to help you see the difference:
