Product Introduction
As a specialized indoor-focused variant of magnesium oxide (MGO) boards, this product features a precision-crafted composition of high-purity magnesium oxide, multi-layered reinforced glass fiber mesh, food-grade magnesium chloride, and advanced modified inorganic binders. Its innovative inorganic matrix structure inherently eliminates flammability and toxic emissions, while the integrated reinforcement layer boosts structural stability-perfectly suited for the unique demands of interior wall environments (e.g., temperature fluctuations, humidity, and decorative requirements).
Fully compliant with global safety and environmental standards, it holds Class A1 non-combustible certification (GB 8624-2012), meets ASTM E84 (U.S.) and EN 13501-1 (EU) fire performance criteria, and achieves E0-grade formaldehyde emission levels (≤0.1mg/L). This ensures a healthy, fire-safe indoor environment without sacrificing functionality or design freedom.
① Top-Tier Fire Protection for Indoor Safety
Inherent Non-Combustibility: Classified as A1-grade non-combustible, the board remains structurally intact even at temperatures up to 1200℃, with no burning, melting, or release of flammable gases under direct flame exposure.
Toxic-Free Combustion Response: In high-temperature scenarios, it emits zero toxic fumes (e.g., formaldehyde, cyanide) or dense smoke, safeguarding indoor occupants and reducing fire-related health hazards-critical for public spaces, homes, and healthcare facilities.
Extended Fire Resistance Rating: Delivers 60–120 minutes of fire resistance (depending on thickness: 10mm ≥ 60min, 12mm ≥ 90min, 15mm ≥ 120min), outperforming traditional gypsum boards and plywood, and meeting strict fire codes for residential and commercial buildings.
② Eco-Friendly & Health-Conscious Design
Ultra-Low Formaldehyde Emission: E0-grade certification ensures formaldehyde levels are well below international indoor air quality standards (e.g., EU E0, U.S. CARB P2), eliminating "sick building syndrome" risks and making it safe for bedrooms, nurseries, and hospitals.
100% Inorganic & Non-Toxic: Free of volatile organic compounds (VOCs), heavy metals, or harmful additives, the board's natural mineral composition aligns with green building trends and sustainable construction requirements.
Mold & Mildew Inhibition: Inorganic materials create an environment hostile to mold and mildew growth (compliant with ASTM G21-15 standards), making it ideal for humid indoor areas like bathrooms, kitchens, and basements.
③ Versatile Decorative Potential & Easy Installation
Customizable Surface Options: Available in a range of finishes-plain, sanded, embossed, melamine-coated, PVC-coated, or pre-painted-compatible with diverse interior design styles (modern, minimalist, industrial, or classic). It can be directly painted, wallpapered, or tiled without the need for additional substrate layers.
Lightweight & Easy to Process: With a density of 1.1–1.3g/cm³ (lighter than standard MGO boards), it can be cut, drilled, and sanded using common woodworking tools, reducing labor costs and shortening construction timelines.
Seamless Installation Experience: Standard sizes (1220×2440mm/4×8ft, 1220×3050mm/4×10ft) fit most interior wall dimensions. It can be fixed with anti-rust screws or adhesives, and joints can be easily sealed with putty for a smooth, professional finish.
④ Long-Lasting Durability & Low Maintenance
Exceptional Structural Stability: The reinforced glass fiber mesh layer enhances bending strength (≥10MPa) and tensile strength (≥3MPa), preventing deformation, cracking, or warping even in fluctuating temperatures (-40℃ to 80℃).
Superior Moisture Resistance: With a 24-hour water absorption rate of ≤12%, it resists swelling and delamination in humid environments, ensuring long-term performance in moisture-prone areas.
Low Maintenance Requirements: A service life exceeding 20 years with proper installation; routine cleaning only requires a damp cloth to remove dust or stains-no special treatments needed.
Magnesium oxide wall board is a technologically advanced building material that offers superior performance in every category when compared to traditional wood, gypsum and cement based products.
Magnesium Oxide Wall Panels are cementitious substrate products reinforced with magnesium oxide fibre matting.
Fire resistant magnesium oxide wallboard is a new type of refractory material. It is widely used primarily as a wallboard alternative to conventional gypsum-based drywall and plywood.
It is non combustible and fire rated Class A1. With options for up to a 2 hour fire resistance, MgO Board offers an innovative passive fire protection alternative for your construction projects.
MgO board has very good fire performance. It does not spread flames or smoke. It is noncombustible and fire-rated A1, which helps protect homeowners, tenants and building occupants while mitigating damage and loss.
Magnesium oxide wall board is made of magnesium oxide, magnesium sulfate or magnesium chloride, glass fiber mesh, perlite and wood fiber.
It is an upgraded product of fireboard. A properly constructed assembly with our MgO fireproof wall board can achieve a 3-hour fireproof rating.
Fire Resistant Internal Wall Board
Our Fire Resistant Internal Wall Board is a fiberglass reinforced magnesium oxide cement board. It can be used to replace traditional gypsum drywall for wall and ceiling finishes and sheathing.
Fireproof Exterior Wall Panels
Magnesium oxide board is a new type of fire-resistant building material. The main raw materials are magnesium oxide, magnesium chloride/sulfate and perlite.
We are a company dedicated to magnesia cement products. Our main products are Magnesium Oxide Boards (MGO Board) for construction and laminated MgO boards for furniture and renovation. Our mission is to provide the world's construction markets with environmentally friendly, high-performance and sustainable green materials.
We work with China Magnesium Materials Association (CMMA) and Magnesium Oxide Association (MOCA) in North America to raise awareness and promote the use of magnesium oxide cement products. We focus on the quality control and consistency of the MGO products. We have been actively involved in developing American Society for Testing and Materials (ASTM) standards related with MGO products.

Installation & Maintenance Guidelines
Installation Steps & Tips
Substrate Preparation: Ensure the wall substrate is flat (tolerance ≤3mm/m), clean, and dry. Remove any dust, oil, or debris to ensure proper adhesion.
Cutting & Fixing: Use a circular saw or utility knife for precise cutting. Attach the board to wooden or steel studs with anti-rust self-tapping screws (spacing: 200–250mm), leaving a 3–5mm expansion gap at edges and corners to accommodate thermal expansion.
Joint Treatment: Fill gaps between boards with waterproof putty, embed fiberglass tape to prevent cracking, and sand the surface smooth once the putty is fully cured.
Finishing Touches: The board's surface is ready for direct painting, wallpaper application, or tile installation-no additional plastering or priming is required (sanded finish recommended for painting/wallpapering).
Maintenance Recommendations
Clean the surface with a soft, damp cloth to remove dust or stains. Avoid abrasive cleaners that could scratch or damage the finish.
Repair any scratches or cracks promptly with waterproof putty to prevent moisture penetration and maintain structural integrity.
Protect the board from prolonged direct water exposure (e.g., leaking pipes) to preserve its performance and appearance.
