Fireproof A1 Grade MGO Board Magnesium Oxide Board Ceiling

 

 

Advantage of Fireproof A1 Grade MGO Board Magnesium Oxide Board Ceiling

 

1. Fire Resistance 

Certified Fire Rating: Complies with EN 13501-1 and ASTM E136 standards, achieving A1 Class Non-Combustible rating-does not burn, ignite, or spread flames even when exposed to 1200°C high temperatures.

Structural Stability Under Fire: Maintains integrity for 60–120 minutes (depending on thickness) at 800°C, preventing ceiling collapse during fire incidents and winning critical evacuation time.

Safety in Fire Scenarios: No toxic smoke, corrosive gas, or molten drips are released when heated, eliminating secondary hazards caused by burning ceiling materials.

2. Lightweight & Load-Bearing Balance

Optimized Thickness for Ceilings: 6–8mm for lightweight suspended ceilings (suitable for residential spaces); 10–12mm for heavy-duty ceiling systems (commercial/public areas with lighting and ventilation installations).

Low Density & High Strength: Density ranges from 800–1000 kg/m³, significantly lighter than cement fiber boards, reducing the load on ceiling keels and building structures.

Anti-Sagging Performance: Flexural strength ≥12 MPa, resisting long-term deformation or sagging caused by its own weight or mounted equipment (e.g., spotlights, air vents).

3. Moisture & Mold Resistance

Waterproof Mechanism: Dense crystal structure with no hydrophilic gaps, fundamentally preventing water vapor penetration; water absorption rate ≤18% (tested per GB/T 7019 standard).

Humidity Stability: No swelling, warping, or cracking in high-humidity environments (e.g., bathrooms, kitchens, basements, coastal areas); maintains dimensional stability with deformation rate <0.2% under dry-wet cycles.

Mold & Insect Proof: Inorganic composition does not support mold, mildew, or termite growth, avoiding ceiling decay and odor issues common with organic ceiling materials.

4. Acoustic & Thermal Insulation

Sound Absorption: The porous internal structure of lightweight fillers (perlite/vermiculite) effectively absorbs medium and low-frequency noise, with a sound insulation index of 30–38 dB-reducing noise transmission between floors and improving indoor comfort.

Thermal Insulation: Low thermal conductivity (0.18–0.22 W/m·K), helping to stabilize indoor temperatures and reduce energy consumption for heating and cooling systems.

5. Environmental Safety & Durability

Zero Harmful Substances: Free of asbestos, formaldehyde, benzene, and radioactive elements, meeting E1 Class environmental standards; suitable for sensitive spaces such as hospitals, schools, and kindergartens.

Long Service Life: Resists aging, yellowing, and fading under UV exposure; service life of 30+ years under normal use, far exceeding the 5–10 year lifespan of PVC or gypsum ceilings.

Easy Maintenance: Smooth surface is stain-resistant and washable; minor scratches can be repaired with paint without replacing the entire panel.

 Application Scenarios

1. Residential Buildings

Suspended ceilings for living rooms, bedrooms, kitchens, and bathrooms-resisting moisture and fire hazards from cooking and bathing.

Basement and attic ceilings-solving mold and deformation issues caused by high humidity.

Integrated ceiling systems-serving as a fireproof substrate for aluminum gusset plates or PVC decorative panels.

2. Commercial & Public Spaces

Shopping malls, hotels, office buildings, and hospitals-meeting strict fire safety requirements for public gathering places.

Schools, libraries, and elderly care facilities-prioritizing environmental safety and acoustic insulation.

Cinema, theater, and KTV ceilings-combining fire resistance with sound absorption to improve audio effects.

3. Industrial & Special Spaces

Light industrial workshops, warehouses, and logistics centers-resisting fire risks from electrical equipment and goods storage.

Subway stations, tunnels, and airport terminals-withstanding high-frequency vibration and maintaining structural stability.

Chemical plants and power plants-resisting corrosion from mild chemical fumes in the air.

 

Installation & Construction Points

Keel Installation: Use galvanized light steel keels (main keel spacing 800–1000mm, auxiliary keel spacing 400–600mm) to build a stable ceiling frame; ensure the frame is level and firm.

Board Cutting: Cut the MgO ceiling board to the required size with a circular saw or utility knife; polish the cut edges to avoid sharp burrs.

Fixing Method: Use corrosion-resistant self-tapping screws (length 20–25mm) to fix the board to the auxiliary keels; screw spacing 200–250mm, and keep 10–15mm from the board edges to prevent cracking.

Seam Treatment: Fill the 3–5mm expansion joints between boards with waterproof joint compound; paste fiberglass tape over the joints and smooth the surface to prevent cracking caused by temperature changes.

Surface Finishing: The board surface can be directly painted, pasted with wallpaper, or covered with decorative films; for humid environments, apply a layer of waterproof paint to enhance moisture resistance.

Storage Requirements: Store the boards in a dry, ventilated place; avoid stacking them directly on the ground, and prevent rain or moisture from soaking the boards.
