Composition of Fireproof MGO Sheet

MGO (Magnesium Oxide Board) panels are produced from a mixture of natural materials, compressed under high pressure and dried at controlled temperatures. Main ingredients include:

• MgO (magnesium oxide): accounting for about 45%, is the core component that creates fire resistance. The melting temperature of MgO reaches 2,852°C, much higher than most common construction materials.
• MgCl2 (magnesium chloride): about 15%, acts as a binder, helping to bind the ingredients together into a solid block.
• Perlite stone (perlite): about 5%, is an expanded mineral with a porous structure, helping to reduce weight and increase thermal insulation.
• Man-made synthetic fibers: about 30%, replacing traditional fiberglass mesh, reinforcing the panels against bending and compressive forces.
• Other additives: about 5%, including hardness, moisture and setting time regulators.

MGO panels do not contain asbestos, formaldehyde or benzene, so they are safe for users and environmentally friendly. The surface of the plate has two sides: a glossy side and a rough side. The rough side helps increase adhesion when applying paint or coating. Fireproof MGO panels distributed by Oval Vietnam are genuine imported goods, packaged on pallets, usually 120 panels per pallet.

Detailed Technical Specifications of MGO Sheets

Below are typical technical specifications of popular fireproof MGO panels on the Vietnamese market:

Why Choose Fireproof MGO Panels for Room Partitions

Room partitions in houses, offices, schools, hospitals, factories... all need a material that is both light, strong enough, and meets fire protection requirements. MGO panels meet these three factors simultaneously.

Fire resistance: The panels are class A1 — the highest level in the fire response classification, meaning the material is non-combustible and does not contribute to the spread of fire. When exposed to fire, MGO panels do not produce toxic smoke, which is an important advantage because smoke is the main cause of death in fires.

Moisture-proof and mold-proof: The waterproof rate is up to about 95%. The panels are not deformed or destroyed when exposed to moisture, and the surface does not support mold growth. This is especially useful in humid climates like Vietnam, and is suitable when constructing partitions in kitchen areas, toilets, and loggias.

Soundproofing and heat insulation: The sound insulation coefficient reaches over 44 dB, enough to separate noise between two rooms. Low thermal conductivity (0.169 W/m·K) helps reduce heat transfer, saving cooling and heating energy.

Easy to construct and complete: MGO panels can be cut with a hand saw or electric saw, drilled, and screwed directly into the light steel or wooden frame. Flat surface, ready to putty and paint without complicated treatment.

Compare Fireproof MGO Panels with Plaster

Many investors consider between MGO panels and fireproof plasterboard for partitions. Both are frame-mounted sheet materials, but there are distinct differences in functionality.

Mechanical durability

MGO panels have a much higher flexural strength (18 MPa when dry) than gypsum (usually less than 6 MPa). You can shoot screws and hang light objects on the MGO wall without worrying about cracks or punctures. Plaster is more brittle and easily cracks when impacted.

Moisture resistance

Plaster absorbs water quickly and softens and expands when hydrated — this is why it deteriorates in humid environments. MGO panels are dimensionally stable when moist, do not soften, and do not mold. If the partition is in contact with a humid area such as the kitchen or bathroom, MGO is a better choice.

Price

Gypsum panels are cheaper than MGO panels. A 12mm fireproof plasterboard costs about 120,000–150,000 VND/sheet, while an MGO sheet of the same thickness ranges from 280,000–350,000 VND/sheet. If the budget is tight and the area is dry, plaster is still an acceptable solution. But when long-term durability and moisture resistance are needed, the MGO price difference is a worthy investment.

Fire resistance

Both are class A fireproof, but MGO panels do not emit smoke when exposed to fire, while gypsum releases crystallized water vapor that can cause structural cracks when the temperature is too high. In projects requiring strict fire protection, MGO panels are often given priority.

Construction Process of Room Partitions Using MGO Panels

Construction of partitions with MGO panels is similar to construction of plaster, using U-shaped and C-shaped light steel frame systems. The process includes the following steps:

Step 1: Prepare the Steel Frame

Fix the U frame (tubing) to the floor and ceiling with expansion screws or nails. The standard distance between C-frame bars (vertical bars) is 600 mm center to center. If the wall needs to withstand higher loads, the distance can be reduced to 400 mm. Check the verticality of the frame with a hydrometer.

Step 2: Cut MGO Sheet According to Size

Standard 1,220 × 2,440 mm MGO panels usually need to be cut to the actual height of the room (usually 2,700–3,000 mm from floor to ceiling). Cut with a fine-tooth hand saw or an electric undercarriage saw. Wear a mask and goggles because cutting dust can cause irritation.

Step 3: Install the MGO Sheet to the Frame

Drive self-tapping screws at 200–250 mm intervals along the frame bars. Screw from the center to the edge to avoid cracking. When installing two layers of panels, the second layer compensates the joint compared to the first layer, the screws are longer corresponding to the total thickness of the two layers plus the frame.

Step 4: Joint Processing and Finishing

Use mesh tape or paper to tape the joints, then seal them. The surface of MGO panels is flat and adheres well to putty and paint. Wallpaper can be pasted, laminated or painted directly. If higher sound insulation is needed, rockwool can be stuffed into the space between the two layers of panels before installing the second layer.

Choose the Suitable MGO Sheet Thickness for the Partition

Choosing MGO sheet thickness directly affects soundproofing, load-bearing capacity and cost. Below is a selection guide by application:

• 5–6mm: Suitable for non-load-bearing interior partitions, decorative walls, and door core panels. Light weight, easy to install, low cost. Should not be used for partitions that require high sound insulation.
• 8mm: The most popular choice for room dividers in homes and offices. Hard enough, soundproof enough, moderate weight. One layer of 8mm per side with a standard steel frame is the standard configuration for most interior partitions.
• 10–12mm: Used for partitions that need to withstand higher forces, exterior walls, and public area walls that are subject to impact. You can use one thick layer instead of two thin layers to save frames.
• Double layer (2×8mm or 2×10mm): Used for partitions that require high sound insulation (meeting rooms, studios, server rooms) or require fire resistance level EI60 or higher. The double layer also helps cover joints, increasing surface flatness.

If you are constructing a regular bedroom or office partition, one layer of 8mm panels on each side is enough. If the partition is between the karaoke room and the residential area, it is recommended to use two layers of 10mm with rockwool stuffing.

Notes When Buying and Installing MGO Panels

Check plate quality: Good quality MGO panels have a flat surface, uniform color, no cracks, no air holes. Pick up the plate and tap gently to hear a solid sound, not buzzing like a hollow plate. Avoid buying panels with crow's feet on the surface — a sign of low density or poor pressing technology. MGO panels from Oval Vietnam have quality certification and clear specifications on each shipment.

Notes on humidity during storage: Although MGO panels resist moisture better than plaster, during storage and transportation, it is necessary to keep the panels horizontal on a flat surface, avoiding direct contact with rainwater or wet ground. If the panel is soaked in water for many days, the surface may become yellow even though the structure is not damaged.

Select included accessories: Use self-drilling screws specifically for MGO panels (disk head screws, anti-rust zinc plated). Light steel frames should be standard galvanized, 0.6–0.8mm thick. Joint mesh tape should choose fiberglass to prevent cracking. Avoid using silicone caulk instead of screws — MGO panels are heavier than plaster and require a sturdy screw mechanism.

Who should not use MGO panels? If you only need temporary partitions, have a lifespan of less than 2 years, and are on an extremely limited budget, standard plasterboard will be significantly cheaper. Similarly, if you need ultra-light partitions (less than 5 kg/m²), PVC panels may be more suitable, although their fire resistance is much less.
