Product Introduction
Magnesium Oxide Boards MGO Fireproof Panels for Ceilings
Magnesium Oxide Board (MGO Board), also known as Glass Magnesium Board or Magnesium Board, is a composite building material with magnesium oxide (MgO) as the core raw material. It is composed of activated high-purity magnesium oxide, magnesium chloride (MgCl₂) or magnesium sulfate (MgSO₄), alkali-resistant glass fiber cloth, plant fibers, lightweight perlite, and polymer additives.

Withstands 800℃ high temperature for 2-3 hours while maintaining structural integrity.
Releases water vapor when exposed to fire to inhibit flame spread, with no toxic smoke emission.
2. Moisture & Water Resistance
Non-absorbent and impermeable; no deformation or swelling in humid environments.
Ideal for kitchens, bathrooms, basements, and other damp areas (prevents mold growth).
3. High Strength & Durability
Flexural strength reaches 12-18MPa (2-3 times that of ordinary gypsum board).
High impact resistance, no easy deformation or cracking; service life exceeds 50 years.
Aging-resistant, corrosion-resistant, and unaffected by termites or insect infestation.
4. Environmental Friendliness & Health Safety
Asbestos-free, formaldehyde-free, and radiation-free (non-toxic and harmless).

Processability: Easier to cut with less tool wear; can be processed with ordinary woodworking tools.
Water Resistance: Similar performance, but MGO Board offers better stability in long-term humid environments.
Environmental Friendliness: Lower production energy consumption and CO₂ emissions, meeting green building standards.
Installation Methods & Precautions
1. Preparation
Tool List: Tape measure, chalk line, utility knife, straightedge, electric saw (carbide blade), screwdriver, hammer, safety gear (goggles, mask).
Material Preparation: MGO Board, rust-resistant screws (316 stainless steel is preferred), washers, sealant, joint tape, putty.
Substrate Treatment: Ensure the ceiling structure is firm, flat, dry, clean, and free of oil or dust.
2. Installation Steps
① Measurement & Cutting
Accurately measure the ceiling dimensions, plan board layout, and reserve 5-8mm expansion joints.
Cut thin boards (≤6mm) with a straightedge and utility knife; use an electric saw for thick boards (>6mm) to ensure straight cuts.
Wear a dust mask during cutting to avoid inhaling magnesium oxide dust.
② Board Fixation
Start installation from the center of the room and expand outward to reduce stress concentration.
Use rust-resistant screws with a spacing of 200-250mm; keep screws ≥12mm from board edges and ≥50mm from corners.
Drive screws perpendicular to the board surface, ensuring tight fixation without over-tightening (to prevent cracking).
③ Joint Treatment
Leave 3-5mm gaps between boards and fill with elastic sealant or special joint compound.
Cover joints with glass fiber mesh tape and apply special putty for a smooth surface.
Additional waterproofing (e.g., waterproof glue) is required for humid areas.
3. Key Precautions
Expansion Space: MGO Board expands slightly with temperature/humidity changes; expansion joints are mandatory (especially for large-area installations).
Fastener Selection: Avoid ordinary iron nails (prone to rust); use 316 stainless steel screws or corrosion-resistant special screws.
Board Protection: Prevent scratches or impacts from sharp objects during installation.
Dust Protection: Cutting dust irritates the respiratory system; ensure ventilation and wear protective gear.
Maintenance & Care Tips
Daily Cleaning: Wipe with a damp cloth (no special cleaners needed); avoid strong acids or alkalis.
Regular Inspection: Check annually for cracks or deformation, especially at edges and joints.
Waterproof Maintenance: For humid areas (bathrooms/kitchens), inspect waterproof sealing every 2-3 years and reapply sealant if necessary.
Repair Methods: Patch small damages with cut-to-size MGO Board; replace entire boards for large damages (reserve expansion gaps between new and old boards).
Comprehensive Analysis of Core Differences Between Magnesium Oxide Board (MGO Board) and Gypsum Board
As commonly used building materials, magnesium oxide board (MGO Board/Glass Magnesium Board) and gypsum board have significant differences in performance, application scenarios, and cost, rooted in their raw material compositions and production processes. Below is a detailed comparison from four core dimensions-key performance, application scenarios, installation & maintenance, and cost-effectiveness-to help distinguish their differences accurately and efficiently:
Comparison of Core Performance (Most Critical Differences)
|
Comparison Dimension |
Magnesium Oxide Board (MGO Board) |
Gypsum Board (Ordinary Paper-Faced Gypsum Board) |
Key Conclusion |
|---|---|---|---|
|
Fire Rating |
A1-Class Non-Combustible (Highest Grade)- Melting point of 2800℃; withstands 800℃ high temperature for 2-3 hours- Does not burn, support combustion, or spread flames; no toxic smoke emission- Maintains structural integrity to block fire spread |
B1-Class Flame-Retardant (Medium Grade)- Decomposes, softens, and collapses at high temperatures (≥150℃)- Does not actively burn but may assist combustion and release small amounts of harmful gases- Short fire resistance duration (usually within 30 minutes) |
MGO Board significantly outperforms gypsum board in fire safety, ideal for scenarios with high fire protection requirements |
|
Moisture & Water Resistance |
Excellent (Water Absorption Rate <1%)- Non-absorbent and impermeable; no deformation or swelling in humid environments- Suitable for damp areas such as kitchens, bathrooms, and basements- Prevents mold growth |
Poor (Water Absorption Rate ≥20%)- Easily absorbs water, softens, deforms, and molds- Only applicable to dry indoor environments (e.g., bedrooms, living rooms)- Requires additional moisture-proof treatment (e.g., waterproof paint) in humid areas to avoid damage |
MGO Board is the only viable option for humid environments; gypsum board's moisture resistance is irreplaceable |
|
Strength & Durability |
High Strength & Durability- Flexural strength: 12-18MPa (2-3 times that of ordinary gypsum board)- High impact resistance; not prone to deformation or cracking; service life exceeds 50 years- Aging-resistant, corrosion-resistant, and termite/insect-proof |
Low Strength & Easily Damaged- Flexural strength: only 4-6MPa; prone to breakage and cracking- Service life: 10-15 years; requires regular maintenance and replacement- Susceptible to termite infestation and moisture erosion |
MGO Board offers superior long-term stability and lower maintenance costs compared to gypsum board |
|
Environmental Friendliness & Health Safety |
Asbestos-free, Formaldehyde-free, Radiation-free- Made of natural mineral raw materials and plant fibers; non-toxic and harmless- Low production energy consumption: CO₂ emissions are only 60% of gypsum board- 100% recyclable |
Contains Chemical Additives- Low-cost products may have excessive formaldehyde (residues from adhesives)- High energy consumption during production; difficult to recycle- Some old-fashioned gypsum boards contain asbestos (gradually phased out) |
MGO Board better aligns with green building and healthy living needs, with no environmental hazards |
|
Sound & Thermal Insulation |
Excellent- Sound insulation capacity: >40dB, effectively blocking noise transmission- Thermal conductivity: 0.18-0.22W/m·K, providing good thermal insulation |
Average- Sound insulation capacity: 30-35dB; limited soundproofing effect (requires additional sound insulation layer)- Thermal conductivity: 0.3-0.4W/m·K, weak thermal insulation performance |
MGO Board has advantages in acoustics and energy efficiency |
|
Dimensional Stability |
High- Minimal deformation or warping due to temperature and humidity changes- Only small expansion joints (5-8mm) need to be reserved |
Poor- Prone to expansion, contraction, and warping with temperature/humidity changes- Frequent expansion joints required for large-area installations to avoid cracking |
MGO Board maintains flatness more easily after construction, reducing later maintenance |
