Overview of Gypsum Wallboard and MgO Board
Gypsum Wallboard: Composition and Features
Gypsum wallboard, also called drywall, is made from gypsum. Gypsum is a natural mineral with tiny air pockets inside. These air pockets make up half its volume. This design makes it light and easy to install.
A key feature of gypsum wallboard is fire resistance. Water inside the gypsum slows fire spread, making it safer. During production, foam bubbles are added to the gypsum mix. This improves how well it works in buildings.
Reports show gypsum wallboard sales will grow fast. By 2032, sales might reach $65.2 billion, up from $45.86 billion in 2024. This shows its popularity in homes and businesses.
Feature | Description |
|---|---|
Core Structure | Tiny air pockets in gypsum make it lightweight. |
Fire Resistance | Water inside gypsum helps stop fires from spreading. |
Fastening Strength | Tested for strength using ASTM standards. |
Manufacturing Process | Foam bubbles added to improve performance. |
MgO Board Wallboard: Composition and Features
MgO board wallboard is made from magnesium oxide and other materials. These include magnesium chloride, perlite, and fiberglass mesh. This mix makes it strong and water-resistant. It comes in thicknesses from 3mm to 20mm for different uses.
One major feature is its fireproof rating of A1. This means it can handle high heat without breaking down. MgO boards also resist moisture well, moving only 0.1%-0.12%. Their strength, measured at 10-16MPa, makes them tough for busy areas.
Other details include a density of 1000-1100kg/m³ and water tests based on BS EN 12467:2012 standards. These features make MgO boards great for projects needing strong, water-resistant materials.
Thickness options: 3-20mm
Fireproof grade: A1
Flexural strength: 10-16MPa
Density: 1000-1100kg/m³
Key Material Properties Comparison
Gypsum wallboard and MgO board wallboard have clear differences. Gypsum wallboard is light, cheap, and simple to install. It works well for regular building projects. MgO boards are stronger, resist fire better, and handle water well. They are best for tough conditions.

Both materials have benefits. Choose based on your project needs.
Detailed Comparison of Gypsum Wallboard and MgO Board
Fire Resistance
Both gypsum wallboard and MgO board protect against fire, but they differ. Gypsum wallboard can resist fire for up to 2 hours. This is because gypsum contains water, which slows flames. However, it may weaken under long heat exposure.
MgO board is much better at handling fire. It can resist fire for 4 hours or more. Even in extreme heat, it stays strong and does not break. This makes it a safer choice for fire-risk areas.
Key Fire Resistance Facts:
Gypsum wallboard: Fire rating up to 2 hours.
MgO board: Fire rating of 4+ hours and stays strong under heat.
Moisture Resistance
Moisture affects these materials differently. Gypsum wallboard does not work well in wet places. Water can make it swell, weaken, or fall apart. This makes it unsuitable for bathrooms or basements.
MgO board resists water very well. It absorbs very little water, moving only 0.1%-0.12%. This makes it great for wet or humid areas. For kitchens, bathrooms, or outdoor projects, MgO board lasts longer against moisture.
Durability and Strength
Strength and durability are important in construction. Gypsum wallboard is light and easy to use but damages easily. It works fine for normal use but not for heavy-duty areas.
MgO board is stronger and lasts longer. Tests show it resists bending, cracking, and wear. It also handles freezing and thawing well. This makes it perfect for busy areas or tough projects.
Characteristic | Gypsum Wallboard | MgO Board |
|---|---|---|
Flexural Strength | Moderate | High |
Freeze/Thaw Resistance | Limited | Excellent |
Compression Indentation | Prone to damage | Highly resistant |
Long-Term Durability | Good for normal use | Best for tough conditions |
For strong and lasting results, MgO board is the better pick.
Cost and Affordability
Gypsum wallboard costs less and fits tight budgets. It is easy to find in stores and cheap to make. This makes it a good choice for big projects needing many materials.
MgO board costs more because of its better features. It resists fire, water, and damage, which raises its price. Though it costs more upfront, it lasts longer and needs fewer repairs. This can save money over time.
Feature | Gypsum Wallboard | MgO Board |
|---|---|---|
Initial Cost | Low | High |
Long-Term Value | Moderate | Excellent |
If you need a low-cost option, gypsum wallboard works well. For stronger and longer-lasting results, MgO board is worth the extra cost.
Environmental Impact
Gypsum wallboard and MgO board affect the environment differently. Gypsum wallboard uses natural gypsum but takes a lot of energy to make. Recycling is possible but not common everywhere.
MgO board is better for the environment. It uses magnesium oxide, which needs less energy to produce. It is also recyclable and breaks down naturally, leaving less waste. If you care about being eco-friendly, MgO board is the better choice.
Environmental Factor | Gypsum Wallboard | MgO Board |
|---|---|---|
Energy Use | High | Low |
Recyclability | Limited | Excellent |
Biodegradability | Moderate | High |
Installation and Usability
Installing gypsum wallboard takes more time and planning. You might need a special team to install it, which can slow things down. It also needs time to cure, adding to the process.
MgO board is quicker and easier to install. Your current crew can handle it without extra steps or waiting for curing. This saves time and avoids delays. If you want a faster setup, MgO board is the better option.
Tip: Using MgO board can help finish projects on time and avoid setbacks.
Installation Factor | Gypsum Wallboard | MgO Board |
|---|---|---|
Preparation Time | Longer | Shorter |
Crew Requirements | Special team needed | Regular crew can install |
Installation Speed | Moderate | Fast |
Applications of Gypsum Wallboard and MgO Board
Common Applications of Gypsum Wallboard
Gypsum wallboard is popular because it is cheap and useful. It is often used in homes, offices, and factories. Its ability to resist fire and block sound makes it great for walls and ceilings.
Here are some common uses:
Residential buildings: Perfect for walls and ceilings in houses.
Commercial spaces: Used in offices, stores, and restaurants.
Industrial facilities: Works well in warehouses and factories.
Institutional buildings: Found in schools, hospitals, and government offices.
Specialized applications: Used for elevator shafts, separation walls, and soffits.
In North America, gypsum wallboard is very popular. This is because people want eco-friendly buildings and are spending more on homes and offices. Pre-decorated boards are also becoming common since they are easy to install and need little care.
Common Applications of MgO Board Wallboard
MgO board wallboard is strong and handles fire and water well. It is used inside and outside, especially in tough conditions.
Application Area | Benefits of MgO Board Wallboard |
|---|---|
