Product Introduction
MGO structural insulated partition board is a sandwich composite panel with double-layer high-density fire-rated MGO boards as the face layer, and professional thermal insulation core material as the middle layer, reinforced with alkali-resistant glass fiber mesh, inorganic mineral fillers and environmental additives. The whole board forms a solid and integrated structure through high-pressure composite and high-temperature curing, which not only retains the all-round performance of pure MGO board, but also realizes the dual functions of partition space and thermal insulation in one board, and the structural strength is far higher than that of single-layer MGO partition board and traditional partition materials.
This fire rated magnesium oxide structural insulated wall panel (referred to as MGO structural insulated partition board) is a high-performance, integrated inorganic building material engineered for internal partition walls, fire partition walls and space division in residential, commercial and industrial buildings. It innovatively combines the core advantages of traditional MGO board (fireproof, waterproof, eco-friendly) with structural insulation integration design, replacing the cumbersome traditional construction process of "partition board + additional insulation layer". With excellent fire resistance, thermal insulation, structural stability and environmental performance, it is a premium green building material for modern building partition systems, and fully complies with international fire protection and environmental building codes.
Advantages of Fire Rated Magnesium Oxide Structural Insulated Wall Panels Eco-Friendly MGO Board Partition
As a partition board tailored for building space division, its performance is fully optimized for the core demands of partition walls: fire protection, thermal insulation, sound insulation, structural stability and construction efficiency. All performance indicators meet international mainstream building standards, and the core advantages are far superior to traditional partition materials such as gypsum board, cement board and aerated concrete blocks.
1. Super Grade Fire Resistance (Euroclass A1/GB 8624 A1)
- Highest non-combustible grade: The double-layer MGO face layer is certified as Euroclass A1/GB 8624 A1 non-combustible material, and the rock wool/glass wool core layer is also A1 grade, realizing full board A1 fire resistance (no burning, no melting, no dripping).
- Long fire resistance duration: The fire resistance time is adjustable according to the board thickness: 50mm thick board (fire resistance ≥1h), 75mm thick board (fire resistance ≥2h), 100mm thick board (fire resistance ≥3h), fully meeting the fire partition requirements of high-rise buildings, public places and industrial facilities.
- Safe fire performance: No toxic smoke, harmful gas or corrosive fumes are released at high temperatures (up to 1200°C), reducing fire casualties and secondary damage, and complying with ASTM E84 (USA) and BS 476 (UK) fire protection standards.
2. Structural Insulation Integration, Energy-Saving & Efficient
- Excellent thermal insulation: Thermal conductivity of the whole board is as low as 0.035-0.06 W/(m·K) (depending on the core material), which can effectively block heat transfer, reduce building air conditioning/heating energy consumption, and meet the green building energy-saving index.
- One board dual functions: Integrates "partition + insulation + fire protection" into one, replacing the traditional construction process of "installing partition first, then laying insulation layer", saving 50% of the construction time and reducing the overall project cost.
- No additional insulation treatment: The board can be directly used as an external partition wall of the building and an internal partition wall of the thermal insulation zone, without secondary pasting of insulation materials, avoiding the problems of insulation layer falling off and delamination.
3. Superior Waterproof, Moisture-Proof & Mold-Resistant
- Inorganic water-repellent structure: The double-layer MGO face layer is made of inorganic non-organic materials, with water absorption ≤8% (premium grade), no swelling, no warping, no disintegration even in long-term high-humidity environments or short-term water immersion.
- Mold-free from the root: No cellulose, starch or other organic components that support microbial growth, fundamentally preventing mold, mildew and algae breeding, suitable for high-humidity partition scenarios such as basements, kitchens, bathrooms, coastal areas and rainy areas.
- Moisture resistance without deformation: Excellent dimensional stability, moisture expansion rate ≤0.10%, no shrinkage, no cracking, no deformation under the change of ambient temperature and humidity (temperature range: -40°C ~ 80°C), and the board shape remains stable for a long time.
4. Strong Structural Stability & Anti-Impact Performance
- High flexural and compressive strength: The whole board has a compressive strength ≥30 MPa and a flexural strength ≥15 MPa, which can withstand the daily impact of buildings (e.g., collision of furniture, construction vibration) without damage, and the structural strength is 3-5 times that of gypsum board partition walls.
- No frame/simple frame optional: The thick board (≥75mm) can be directly installed as a non-frame partition wall, and the thin board (50mm) can be matched with light steel keel for installation, both of which have good structural stability and no collapse risk.
- Anti-settling and anti-cracking: The board has low shrinkage rate (≤0.05%), no post-construction settlement and crack problems, and the joint of the partition wall is firm and beautiful, avoiding the common quality problems of traditional partition materials.
5. Excellent Sound Insulation Effect, Create Quiet Space
- Integrated sound insulation design: The sandwich structure of "double-layer dense MGO face layer + porous insulation core layer" forms a multi-layer sound insulation barrier, which can effectively absorb and isolate air-borne sound and solid-borne sound.
- High sound insulation index: The weighted sound reduction index (RW) of the whole board is ≥40 dB (100mm thick) and ≥35 dB (75mm thick), which can fully meet the sound insulation requirements of residential 分户 walls, hotel guest room partitions, hospital ward partitions and office space partitions, and isolate indoor noise effectively.
6. 100% Eco-Friendly & Healthy, Meet Indoor Air Quality Standards
- Zero harmful substance release: No formaldehyde, no asbestos, no heavy metals (lead, mercury, cadmium), no volatile organic compounds (VOCs), and the emission of harmful substances is far lower than the EU REACH and Chinese GB 50325 indoor environmental standards.
- Natural and recyclable raw materials: The core raw materials are natural magnesium oxide, inorganic minerals and recycled glass fiber, the whole board is 100% recyclable, and the waste board can be crushed and reused as building raw materials, with low carbon footprint and in line with the concept of green and low-carbon buildings.
- Hygienic and easy to clean: The surface of the MGO face layer is smooth and dense, easy to clean and disinfect, and can be used for partition walls in hygienic-sensitive places such as hospitals, food factories and kindergartens.
7. Lightweight & Easy Installation, Shorten Construction Period
- Lightweight design: The density of the whole board is only 350-600 kg/m³, which is 1/3 of aerated concrete blocks and 1/2 of cement partition boards, reducing the structural load of the building and suitable for high-rise buildings and light steel structure buildings.
- Simple construction process: Can be cut, drilled, nailed and screwed on site with ordinary construction tools (utility knife, circular saw), no special equipment is needed; the board is prefabricated in factory, with standard size, and the on-site assembly is fast, with a single worker constructing up to 20 m² per day.
- Flexible splicing: The board is designed with tongue-and-groove joint, which can be spliced tightly, and the joint is filled with MGO special sealant to ensure the airtightness, water tightness and sound insulation of the partition wall; the board can be cut arbitrarily according to the space size, adapting to irregular space division.
8. Insect-Proof, Anti-Corrosion & Long Service Life
- Inorganic material characteristics: No wood fiber or organic components, no termite, rat, cockroach and other insect infestation, suitable for partition walls in tropical and subtropical areas with serious insect damage.
- Corrosion resistance: Resistant to acid and alkali corrosion, salt spray erosion (suitable for coastal areas) and chemical gas corrosion (suitable for light industrial factories), no rust, no rot, no aging.
- Ultra-long service life: Under normal installation and daily maintenance, the service life of the board is more than 50 years, which is consistent with the service life of the main building, and no frequent replacement and maintenance are needed, reducing the later operation and maintenance cost.

Fire Rated Magnesium Oxide Structural Insulated Wall Panels Eco-Friendly MGO Board Partition
Professional Installation Guidelines (Partition Wall Special)
MGO structural insulated partition board adopts factory prefabrication + on-site assembly construction mode, with simple process and low requirements for construction workers. It can be installed in two ways: light steel keel fixation (suitable for 40-50mm thin board) and direct splicing (no keel) (suitable for 75-150mm thick board). The following is the standard professional installation process, which is applicable to most building partition scenarios:
Pre-Installation Preparation
- On-site measurement & board cutting: Measure the actual height and width of the partition wall on site, and cut the board to the required size with a circular saw (diamond blade) or utility knife; reserve 2-3mm expansion gap at the top/bottom and side of the board to adapt to temperature and humidity changes.
- Material preparation: Prepare corrosion-resistant fasteners (stainless steel self-tapping screws/rivets), MGO special joint compound, environmental friendly sealant, light steel keel (optional), waterproof tape and other auxiliary materials.
- On-site cleaning: Clean the ground and wall of the installation area, ensure the base is flat, firm and free of debris; mark the installation line of the partition wall to ensure the verticality and straightness of the partition wall.
- Board acclimatization: Place the board in the installation area for 24 hours of acclimatization (ambient temperature: 18-24°C, humidity: 40%-60%) to avoid deformation caused by temperature difference.
Standard Installation Steps (Light Steel Keel Fixation - Most Commonly Used)
- Install light steel keel: Fix the vertical light steel keel on the ground and ceiling with expansion bolts, the keel spacing is 400-600mm (consistent with the board width); install the horizontal keel at the top and bottom for reinforcement to ensure the keel is vertical and horizontal.
- Fix the MGO board: Align the board with the keel, and fix the board on the light steel keel with stainless steel self-tapping screws (screw diameter: 4.2mm, length: 25-30mm); the screw spacing is 200-250mm, and the screw is 10-15mm away from the board edge to avoid edge cracking.
- Splice the board: Adopt staggered splicing for the board joints (no vertical joint alignment) to enhance the structural stability of the partition wall; paste waterproof tape on the board joints to improve the waterproof and sound insulation effect.
- Seal the gaps: Fill the expansion gap at the top/bottom/side of the board with MGO special joint compound, and apply environmental friendly sealant on the surface for sealing; fill the screw holes with joint compound and smooth it to avoid water seepage and air leakage.
- Finish the surface: After the joint compound is completely cured (24-48h), the surface of the board can be directly subjected to finishing treatment (paint, wallpaper, tile, veneer, etc.) without additional puttying (the board surface is smooth and dense).
Installation Steps (No Keel Direct Splicing - Thick Board ≥75mm)
- Vertical splicing of boards: Align the pre-cut boards with the installation line, and splice the boards tightly with tongue-and-groove joints; fix the adjacent boards with stainless steel rivets (rivet spacing: 300mm) for reinforcement.
- Fix the board to the base: Fix the two ends of the board on the existing wall/column with expansion bolts (spacing: 500mm) to ensure the partition wall is vertical and firm; install the anti-collision strip at the bottom of the board (optional) to prevent ground water seepage.
- Seal and reinforce: Fill all splicing gaps with MGO special joint compound and sealant; paste the corner guard at the partition wall corner (stainless steel/plastic) to enhance the anti-impact performance of the corner.
Key Installation Notes
- Corrosion resistance: All fasteners must use stainless steel or hot-dip galvanized products to avoid rusting and board falling off caused by moisture.
- Verticality control: Use a level to check the verticality of the partition wall during installation, the vertical deviation is ≤2mm/m to ensure the beauty and structural stability.
- Curing time: The joint compound and sealant must be completely cured before surface finishing to avoid cracking and peeling of the finish layer.
- High-humidity scene: For kitchen, bathroom and basement partition walls, apply a layer of waterproof coating on the board surface (1.5-2.0m high from the ground) to further improve the waterproof effect.
