It has certifications like ESL-1290 for fire resistance up to two hours.
Lab tests on over 1,000 samples in two years show the board stays strong in fire. The binder in the board turns into magnesium oxide when hot. This makes it even better at stopping fire. Hydrated minerals in the board let out water when heated. This helps slow fire and cuts down smoke. Magnesium wall board does not add toxic smoke, so it is safer for indoor air.
Magnesium oxide board is safer than resin particle boards. It does not make toxic gases or fumes in a fire. This helps keep people in buildings healthier.
No Harmful Gases or VOCs
Magnesium oxide mixes with water to make magnesium hydroxide. When it gets hot, magnesium hydroxide lets out only water vapor. This is why magnesium wall board does not make bad gases or fumes when burning. The water vapor helps slow fire and lowers smoke.
Aspect | Magnesium Oxide (MgO) Board | Particle Board |
|---|---|---|
Combustibility | Non-combustible, lasts in fire up to 4 hours | Burns easily, fire resistance less than 1 hour |
Smoke Emission | Makes very little smoke in fire | Makes a lot of smoke and toxic fumes |
Toxic Chemicals | No formaldehyde or VOCs, no bad chemicals | Has urea-formaldehyde resin that lets out formaldehyde and VOCs that can hurt lungs and cause cancer |
Health Risk from Smoke | Low risk because smoke is not toxic | High risk because smoke is toxic |
Magnesium oxide board only gives off water vapor in fire. So, there are no toxic gases, no bad fumes, and no VOCs in the air. Less smoke and no toxins help protect people from breathing problems. Particle board gives off toxic gases and is more dangerous. Magnesium wall board is much safer.
Magnesium oxide board is also good for the environment. It does not burn or make toxic gases in fire. The board stays strong and protects for up to four hours. It makes very little smoke and no toxic gases, so it is safer for people and nature.
Magnesium oxide board is made from natural minerals and has a low carbon footprint. It can be recycled and does not fill up landfills, which is good for green building.
Magnesium wall board is safe in fires. It does not let out toxic gases, fumes, or VOCs. Only water vapor comes out, so it is one of the safest choices for fire-resistant buildings.
Material Comparison
Magnesium Wall Board vs. Gypsum
Magnesium Wall Board vs. GypsumMagnesium oxide is a great fire-resistant material. It is better than gypsum boards in a fire. Magnesium oxide does not burn at all. It stays strong even when it gets very hot. Gypsum boards can get soft and weak from heat. Both types of boards can stop fire, but magnesium oxide is safer.
Property | Magnesium Oxide (MgO) Boards | Gypsum Boards |
|---|---|---|
Combustibility | Non-combustible; does not burn | Combustible; softens under high heat |
Smoke Emissions | Minimal smoke | Moderate smoke |
Toxic Gas Emissions | No toxic gases emitted | Emits non-toxic gases |

BS476 | UK standard for fire resistance testing of building materials | United Kingdom |
These certifications prove a wall board can handle fire and keep people safe. Some panels get a Class A fire rating. This means flames move very slowly or even stop. Builders use Class A panels in places with more fire danger, like kitchens or hallways. If a product meets these rules, it helps make buildings safer.
Laboratory Findings on Toxicity
Lab tests check if wall boards let out bad gases in a fire. Scientists use special tools to measure gases like carbon monoxide and nitric oxide. In one test, they burned particleboard covered with magnesium compounds. When more magnesium was added, fewer toxic gases came out. Carbon monoxide went down from 1302 ppm to 1091 ppm. Nitric oxide dropped from 415 ppm to 290 ppm. This means magnesium helps lower dangerous gases.
Magnesium oxide boards also go through tests like ASTM E84. These tests look at how fast flames move and how much smoke forms. The results show a flame spread rating of 0/0. This means no flames spread and no smoke is made. The boards do not burn, even at 800°C. This proves they do not let out toxic gases in a fire.
Some labs found that not every magnesium wall board passes all fire tests. Boards with too much organic stuff may not meet the hardest rules. Still, most magnesium wall boards are better at stopping fire than gypsum boards. Their great fire ratings make them a smart pick for safe buildings.
Magnesium wall boards do not catch fire or let out toxic gases. They can handle heat up to 1200°C, which is much hotter than most fires. This makes them safer than drywall or plywood. Experts say to use them in places like schools and hospitals. These boards are strong and do not get damaged by water. They help keep buildings and people safe. Picking magnesium wall boards helps make spaces healthier and safer for all.
