Magnesium Board Stands Out As Preferred Green Fireproof Building Material With Versatile Superior Properties

Industry research data in 2026 reveals that driven by the implementation of the new national standard for combustion performance classification of construction products and rising demands for prefabricated buildings and clean engineering, the market size of glass magnesium boards keeps surging, hitting 42 billion yuan with a year-on-year growth rate of over 27%, outperforming traditional decorative panels by a large margin.

Made of magnesium oxide, magnesium chloride and glass fiber mesh, glass magnesium boards have passed numerous engineering tests and proved outstanding in comprehensive performance. In fire resistance, they reach Class A1 non-combustible grade with a maximum fire resistance limit of 4 hours. Exposed to open flames of 800–1200℃, the panels will not collapse or release toxic smoke. They have become standard partition materials for high fire-risk areas including electronic factories, hospital operating rooms and data centers, effectively slowing fire spread and buying more time for evacuation during fires.

Unlike gypsum and wooden boards prone to damp damage, glass magnesium boards feature great moisture and mildew resistance. They barely absorb water even in 95% high-humidity environments, so they will not swell, deform or grow mold in basements, coastal buildings, kitchens and bathrooms. As inorganic materials, they resist termite erosion and acid-alkali corrosion, with an indoor service life of 30 years and over 15 years for outdoor use, cutting long-term maintenance costs greatly.

Eco-friendliness makes them fit the national carbon peaking and carbon neutrality goals. No formaldehyde, benzene or other harmful volatile substances are generated during production or usage. Major qualified glass magnesium boards have been included in the national green building material catalog, suitable for schools, residential apartments and other enclosed living spaces. Besides, the panels are lightweight yet high-strength, easy to cut, drill and veneer. Their microporous structure provides sound insulation and thermal insulation effects to reduce building energy consumption, widely applied in partition walls, ceilings, ventilation ducts and clean workshop enclosures.

Industry insiders mention that conventional boards can only meet single construction demands, while glass magnesium boards balance fire safety, humidity resistance, environmental protection and workability with few performance defects. Thanks to updated anti-halogen modification technology, exports have expanded rapidly, with orders from European, American and Australian green construction projects jumping 87% year on year. Market analysts predict that glass magnesium boards will occupy an increasingly larger share of Class A fireproof panels in the next five years, acting as all-round new building materials with both safety and low-carbon value.
