Доска оксида магния (MgO board) has become one of the most reliable building materials for modern construction. Known for its огнестойкость, защита от влаги, environmental safety, и долговечность, MgO board is widely used in interior walls, потолки, основания для пола, and exterior cladding systems.

However, selecting the right MgO board for your project requires evaluating several technical factors. This guide provides a clear, professional, and practical approach to help builders, подрядчики, and project managers make the best decision.

1. Check the Fire Rating (A1 Grade Recommended)

Fire safety is a top concern in commercial and residential projects. A high-quality MgO board should meet the A1 non-combustible standard, meaning it will not ignite or contribute to fire spread.

Key fire-performance indicators:

Проверенный A1/A fire rating
Fire resistance up to 800–1000°C
Third-party test reports from accredited laboratories
Suitable for fire-rated walls, лифтовые шахты, corridors, школы, больницы, и общественные здания

Selecting A1-rated MgO boards ensures maximum fire protection and compliance with international safety codes.

2. Evaluate Moisture Resistance and Durability

Moisture stability directly affects service life. Poor-quality boards absorb water easily, leading to deformation, растрескивание, и плесень.

A reliable MgO board should offer:

Water absorption ≤ 15%
High dimensional stability in humid environments
Mold-resistant and anti-bacterial surfaces
No swelling or delamination under prolonged moisture

This makes MgO boards ideal for ванные комнаты, подвалы, кухни, and coastal buildings.

3. Review Material Composition and Mechanical Strength

The core material determines long-term stability.

A high-quality MgO board should use:

High-purity active magnesium oxide
Alkali-resistant fiberglass mesh as reinforcement
Eco-friendly fillers to improve density and toughness

Recommended mechanical properties:

Прочность на сжатие: 8–12 MPa (high-end boards reach 20–40 MPa)
Flexural strength suitable for framing systems
Thermal conductivity: ≤ 0.06 W/(m·K) for better insulation
Density range: 0.85 – 1.5 t/m³ depending on application

These indicators ensure the board can withstand impact, load, and structural stress.

4. Confirm Environmental and Health Certifications

For residential and commercial environments, material safety is essential.

A qualified MgO board should be:

Formaldehyde-free
Без асбеста
Нетоксичный и без запаха
In compliance with ISO environmental certifications
Compatible with LEED green building standards

These features make MgO board suitable for sensitive applications such as школы, больницы, nursing homes, and children’s rooms.

5. Choose the Correct Specifications for Your Project

Most MgO boards come in standard sizes such as 1200 × 2400 мм, which are easy to cut, сверлить, и установить.

Factors to consider:

Толщина (6–20 mm depending on walls, потолки, полы)
Плотность (higher density for flooring or exterior use)
Surface finish (гладкий, sanded, ламинированный)
Installation method (screws, framing systems, adhesives)

For example:

Interior walls / потолки: 6–10 mm
Floor underlayment: 10–12 mm high-density
Exterior panels: 8–12 mm with moisture protection

6. Verify Real Performance Through Case Studies or Manufacturer Tests

A professional supplier should provide:

Fire test reports
Bending strength and compressive strength data
Long-term moisture stability tests
Application case photos or engineering records

7. Compare Cost vs. Производительность

MgO board prices vary depending on thickness, плотность, and surface treatment.

Typical price range:

Standard MgO board: affordable, suitable for indoor partitions
Водонепроницаемый / Structural MgO board: higher cost but better stability
Decorative MgO board: premium finish for visible surfaces

Balancing performance and budget ensures the best value for your project.

Conclusion: Choose Wisely for Long-Term Performance

Selecting the right MgO board is not simply about price—it’s about ensuring безопасность, долговечность, environmental protection, and installation efficiency.
