Magnesium Oxide (MgO) boards are known for their excellent fire-resistant properties. MgO boards typically have a fire rating of A1 or A2, which signifies the highest level of fire resistance according to European standards. Here are some key points regarding the fire rating of MgO boards:
1. A1 Fire Rating: MgO boards are classified as non-combustible materials, a key feature that contributes to their A1 fire rating, the highest fire resistance level. This rating assures that MgO boards do not fuel fires and do not emit significant smoke or toxic fumes when exposed to flames. MagMatrix Perseverance model BMSC 517 new sulfate MGO board meets the ASTM E136 noncombustible grade that meets the ICC & IRC Type I II for the noncombustible contractions to achieve 1-4 hours fire ratings for the steel frame system and with full loads designs and also help you save for the fire rated gypsum layers to maximum the design of the wall system especially for the exterior wall system with our Perseverance new sulfate magnesium oxide board fire rated structurally exterior sheathing panel.
2. A2 Fire Rating: MgO boards may be classified with an A2 fire rating depending on the specific composition and manufacturing process. A2-rated materials are also considered non-combustible and contribute very little to fire, making them highly fire-resistant. Our MagMatrix BMSC 517 news sulfate MGO sheathing panel of the multi-support owns the A2 grade, is specially designed for the timber frame system, and meets the type III V building code for the exterior wall 1-2 hours fire ratings.
3. High-Temperature Resistance: our MagMatrix BMSC 517 new sulfate MgO boards can withstand high temperatures without igniting or releasing harmful gases. This makes them suitable for applications where fire safety is a primary concern, such as building construction, especially for fire-rated walls, ceilings, and facades.
4. Inorganic Composition: The inorganic composition of MgO boards, primarily magnesium oxide, magnesium chloride, and other minerals, contributes to their exceptional fire resistance. These materials do not support combustion and are inherently fire-resistant.
5. Low Smoke and Toxic Gas Emission: When subjected to fire, MgO boards produce minimal smoke and do not release toxic gases, a crucial feature that helps maintain a safe environment in the event of a fire incident.
Overall, MgO boards are favored for their outstanding fire-resistant properties, making them popular for various construction applications where fire safety and compliance with building regulations are essential. Their A1 or A2 fire rating reflects their ability to withstand fire and contribute to overall building safety.
Magnesium Oxide (MgO) boards are renowned for their excellent fire-resistant properties. The fire rating of MgO boards can vary based on the thickness and specific composition of the board, but they generally have high fire resistance ratings. Here are some typical ratings and characteristics:
Fire Resistance Rating: our BMSC 517 new sulfate MgO boards can achieve fire ratings ranging from 1 hour to 4 hours, depending on their thickness and the specific test standards they meet.
Non-Combustible: Our Perseverance model MgO boards are classified as non-combustible, meeting the ASTM E136 noncombustible grade, meaning they do not ignite or contribute to the spread of fire.
Smoke and Toxicity: our BMSC new sulfate MgO boards produce minimal smoke and toxic emissions when exposed to fire, making them a safer option than other building materials.
Standards Compliance: Our MgO boards often comply with various international fire safety standards, such as ASTM E136 (Standard Test Method for Behavior of Materials in a Vertical Tube Furnace at 750°C) and EN 13501-1 (Fire Classification of Construction Products and Building Elements).
It's essential to check the specific manufacturer's documentation for the exact fire rating and certifications of the MgO board you are considering, as these can provide more detailed and accurate information for your specific application.
MagMatrix brand is an industry leader in providing fire-resistant building boards with our BMSC 517 new sulfate MGO board patents. Our new MGO fireproof building boards are made from a composition of magnesium oxide, non-organic minerals, bonders and fiber mesh composites, and metal-corrosive magnesium sulfate (MgSO4). It contains no metal-corrosive Magnesium chloride. Our MgO board is fire-tested and approved by the CCRR from Intertek, ICC-ESR, and EU regulations, with rigorous Fire testing to ensure that every MgO board complies with international market standards.
