Product Introduction
What is Weather-resistant Waterproof Fireproof Safety Inside Outside Magnesium Oxide Board?
As a high-performance green building material, the Weather-resistant Waterproof Fireproof Safety Magnesium Oxide Board (MGO Board) is engineered with advanced formulas and precision production processes. Its core composition-high-purity magnesium oxide, magnesium chloride, reinforced fiber (glass fiber, plant fiber), and special additives-endows it with integrated advantages of weather resistance, waterproofness, fireproofing, and safety. Designed for both indoor and outdoor use, this board breaks the limitations of traditional building materials and provides a reliable, durable solution for global construction projects, complying with international standards such as ASTM, ISO, and CE.
Advantage of Weather-resistant Waterproof Fireproof Safety Inside Outside Magnesium Oxide Board
1. Superior Weather Resistance: Adapt to Global Climates
-
All-weather Adaptability: The board undergoes special surface modification and formula optimization, effectively resisting ultraviolet (UV) radiation, extreme temperatures (-40℃ to +70℃), humidity, and acid-alkali corrosion. It maintains structural stability without cracking, warping, or discoloration even in harsh environments like tropical rainforests, coastal salt-spray areas, or frigid regions.
-
Long-term Durability: After 1000 hours of accelerated weathering tests (including UV aging, thermal shock, and humidity cycling), the board's flexural strength retention rate exceeds 85%, and its service life outdoors can reach 15+ years, significantly outperforming traditional wood-based panels or cement boards.
-
Moisture Resistance: It absorbs less than 10% water after 24-hour immersion, resisting mold, mildew, and termite infestation-ideal for high-humidity areas such as basements, bathrooms, and coastal buildings.
2. Reliable Waterproof Performance: No Leakage for Indoor & Outdoor Use
-
Innate Waterproof Structure: The hydration reaction of magnesium oxide and magnesium chloride forms a dense crystalline structure (5·1·8 phase) with no porous gaps, preventing water penetration from the surface to the core.
-
Waterproof Grade IPX7: It can withstand long-term exposure to water (e.g., outdoor rain, indoor wet areas) without delamination or strength loss. When used as exterior wall cladding or bathroom partitions, it eliminates the need for additional waterproof coatings, reducing construction costs and time.
-
Stable in Wet Environments: Unlike gypsum boards that soften and deform when wet, or wood boards that swell and rot, this MGO board remains intact even in prolonged high-humidity conditions, ensuring consistent performance.
3. Top-tier Fireproof Safety: Protect Life & Property
-
Class A Fire Rating (Non-combustible): The board is made of inorganic materials that do not burn, release toxic gases, or produce smoke when exposed to fire. It can withstand 1200℃ high temperatures for over 2 hours, effectively delaying fire spread and providing valuable evacuation time.
-
Fire Protection Compliance: Meets international fire safety standards such as ASTM E119 (US), EN 13501-1 (EU), and GB 8624 (China), making it suitable for fire-sensitive areas like commercial buildings, hospitals, schools, and industrial warehouses.
-
Structural Integrity Under Fire: Even after prolonged fire exposure, the board does not collapse easily, maintaining partial load-bearing capacity and reducing secondary damage.
4. Environmental & User Safety: Green & Harmless
-
Zero Formaldehyde Emission: Made of inorganic and natural fibers, the board is free of formaldehyde, benzene, heavy metals, and other harmful substances. Its formaldehyde emission is ≤0.02mg/m³, far below the EU E0 standard (≤0.124mg/m³) and US CARB P2 requirements, ensuring healthy indoor air quality.
-
Eco-friendly & Recyclable: The raw materials are non-toxic, renewable, and recyclable, with low carbon emissions during production. It is a green building material certified by LEED and other international green building standards.
-
Safe for Direct Contact: The board's surface is smooth and non-irritating, posing no harm to human skin or respiratory systems. It is suitable for interior decoration (e.g., walls, ceilings) and areas with frequent human contact.
5. Versatile Indoor & Outdoor Application: Multifunctional & Practical
-
Outdoor Applications: Exterior wall cladding, curtain wall backing boards, roof insulation substrates, outdoor kiosks, garden pavilions, and coastal building facades. It can be painted, tiled, or covered with decorative films to meet various aesthetic needs.
-
Indoor Applications: Partition walls, suspended ceilings, floor underlays, bathroom/toilet walls, kitchen backsplashes, and fireproof doors. It is lightweight (density 0.8-1.2g/cm³) and easy to cut, drill, and install, improving construction efficiency.
-
Special Scenarios: Industrial workshops (resisting chemical corrosion and high temperatures), public transportation hubs (fireproof and soundproof), and modular buildings (lightweight and durable).
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.
