Difference Between Boards Overview

Quick Comparison Table

Note: The table above shows the main difference between boards. Each board has strengths for different needs.

Key Differences

The difference between boards like gypsum board and mgo board stands out in several ways. Gypsum board works well for most indoor walls. It installs quickly and costs less. Many builders use it for homes and offices where normal conditions exist. However, gypsum board does not handle water or impact very well. It can break or grow mold in damp places.

Mgo board offers more strength and durability. It resists mold, mildew, and pests. This board also has higher fire resistance, making it a safer choice for places that need extra protection. Mgo board works best in bathrooms, kitchens, basements, and other wet or high-risk areas. It takes longer to install and costs more at first, but it saves money over time because it needs fewer repairs.

The difference between boards also appears in their maintenance needs. Gypsum board often needs repairs in humid areas. Mgo board needs less care and lasts longer. Builders choose mgo board when they want a strong, safe, and long-lasting wall. They pick gypsum board when they want a quick, low-cost solution for dry spaces.

Composition & Properties

Gypsum Board Basics

Gypsum board has a center made from gypsum. This is also called calcium sulfate dihydrate. Factories heat and crush the mineral to take out water. This turns it into plaster of Paris. The core sits between two sheets of paper. The paper comes from old newspapers. Sometimes, it has special coatings. These coatings help with moisture or paint. Other things like starch and paper pulp are added. These help the board stay strong and light. Foaming agents make the board easier to carry.

Here is a table that lists the main materials and what they do:

Gypsum board stops fire because of the water inside. When it gets hot, the water turns to steam. This keeps the board cool. The paper layers make the board strong. They also help when finishing the wall. Special things added to the board can make it lighter, stronger, or better at stopping water and fire.

MgO Board Basics

MgO board is also called magnesium oxide board. It uses different materials than gypsum board. The main part is magnesium oxide. This makes the board strong and good at stopping fire. Magnesium sulfate helps the board resist water. It also keeps the board from swelling or bending. Other fillers like perlite, wood fiber, and fiberglass mesh are added. These make the board stable and tough.

MgO board is special because it can take very high heat. It does not melt or make toxic smoke up to 1200°F. This makes it great for fire safety. Magnesium sulfate and high alkalinity stop mold and mildew from growing. This works even in wet places. Builders use mgo board where water and fire are big problems.

MgO board is strong, stable, and safe for many building jobs. Its special mix of materials helps it last longer and work better in hard places than gypsum board.

Fire Resistance

Gypsum Board Performance

Gypsum board offers good fire resistance for most building needs. The core of gypsum board contains water in the form of crystals. When exposed to heat, this water turns into steam. The steam helps keep the board cool and slows down the spread of fire. Builders often use gypsum board in walls and ceilings because it meets standard fire safety codes. Many homes and offices rely on gypsum board to protect against fire for a set amount of time, usually 30 to 60 minutes.

The paper layers on each side of the board also play a role. They hold the core together during a fire. Some types of gypsum board include extra additives like glass fibers or vermiculite. These additives improve fire resistance and help the board last longer under high temperatures. However, gypsum board will eventually break down if exposed to fire for too long. It works best in areas where basic fire protection is enough.

Tip: Always check the fire rating of the gypsum board before use. Not all types offer the same level of fire resistance.

MgO Board Performance

MgO board stands out for its excellent fire resistance. The main ingredient, magnesium oxide, does not burn or melt at high temperatures. MgO board can handle heat up to 1200°F without losing strength or making toxic smoke. This makes it a top choice for places that need extra fire safety, such as stairwells, exit routes, and kitchens.

Unlike gypsum board, mgo board does not rely on water in its core to stop fire. Instead, its mineral base stays stable even during long exposure to flames. Builders use mgo board in schools, hospitals, and commercial buildings where strict fire codes apply. The board often earns an A1 non-combustible rating, which means it will not add fuel to a fire.

MgO board also resists damage after a fire. It keeps its shape and strength better than gypsum board. This makes it a safer and more reliable option for high-risk areas.

Note: MgO board offers peace of mind for anyone who wants the highest level of fire resistance in their building.

Moisture & Mold Resistance

Gypsum Board in Wet Areas

Gypsum board does not work well in wet places. Its core soaks up water fast. When the air is damp, the board can swell or break. Mold and mildew can grow if it stays wet for a long time. This makes gypsum board a bad pick for bathrooms or kitchens.

Lab tests show gypsum board does not handle water well. The table below shows how it reacts to different humidity:

These results show gypsum board does not do well with water. Even with extra stuff added, it only gets a bit better. Builders often see damage or mold when using it in wet rooms.

Tip: Only use gypsum board in dry rooms. Pick a different board for wet places.

MgO Board in Wet Areas

MgO board is great at stopping water and mold. Magnesium oxide does not soak up water like gypsum. This helps mgo board work well in bathrooms and basements. The board stays strong and does not swell when it gets wet.

Many builders use mgo board where water or damp air is common. The board does not let mold or mildew grow because it stays dry. This keeps walls and ceilings clean and safe. MgO board also works outside or in places with changing weather.

• MgO board keeps its shape when wet.

• It stops mold and mildew from growing.

• The board lasts longer and needs fewer repairs in damp places.

Note: MgO board is the best for stopping water and mold. It keeps buildings safe from water damage and helps the air stay healthy.

Strength & Durability

Impact Resistance

Impact resistance shows how well a board can handle bumps, knocks, or hits. Gypsum board has a soft core. It can dent or break if someone hits it hard. Many builders use gypsum board for walls in homes and offices. These places do not see much rough use. When someone moves furniture or opens a door too fast, the wall may get a dent or hole. Repairs are easy, but they may happen often in busy spaces.

Mgo board has a much tougher core. It uses magnesium oxide and other strong fillers. This board can take more hits without breaking. Schools, hospitals, and public buildings often use mgo board. These places need walls that stay strong even when people bump into them. Mgo board also works well in garages and basements where tools or equipment may hit the wall.

Tip: For high-traffic areas or places where walls may get hit, mgo board gives better protection than gypsum board.

Lifespan

The lifespan of a board depends on how long it stays strong and safe. Gypsum board usually lasts many years in dry, calm rooms. If the room stays dry and people do not hit the walls, gypsum board can last as long as the building. Problems start when the board gets wet or moldy. Water damage can make the board weak. Mold can grow inside the board and spread to other parts of the wall. In these cases, people may need to replace the board sooner.

Mgo board has a longer lifespan in most cases. It resists water, mold, and pests. Even in wet places, mgo board keeps its shape and strength. Builders often choose mgo board for bathrooms, basements, and outside walls. These boards need fewer repairs and last longer than gypsum board. The extra cost at the start pays off over time because the board does not need to be replaced as often.

Choosing the right board for strength and durability helps keep buildings safe and looking good for many years.

Cost & Value

Material Costs

Material cost is a big factor when choosing between gypsum board and mgo board. Gypsum board usually costs less. Most home improvement stores sell gypsum board at a low price. Builders often pick gypsum board for large projects because it helps save money. The price for gypsum board stays steady in most places.

Mgo board costs more than gypsum board. The materials in mgo board are harder to find and make. This board also lasts longer, so some builders see it as a good investment. Mgo board can save money over time because it does not need as many repairs or replacements. People who want strong walls in wet or high-traffic areas often choose mgo board, even with the higher price.

Here is a quick look at average prices:

Note: Prices can change by location and thickness. Always check local suppliers for the best deal.

Installation Costs

Installation costs also matter when picking a board. Gypsum board is light and easy to cut. Workers can install gypsum board quickly with simple tools. This saves time and labor costs. Most builders know how to work with gypsum board, so there are fewer mistakes.

Mgo board takes more time to install. The board is heavier and harder to cut. Workers need special saws and screws for mgo board. This can raise labor costs. Some installers may need extra training to handle mgo board. Even though the first cost is higher, mgo board can lower costs later because it needs less repair.

• Gypsum board: Lower labor costs, faster to install.

• Mgo board: Higher labor costs, but fewer repairs in the future.

Tip: For big projects with a tight budget, gypsum board is a smart choice. For long-term value and tough conditions, mgo board is worth the extra cost.

Environmental Impact

Sustainability

Gypsum board and MgO board affect the earth in different ways. Gypsum board is made from natural gypsum, FGD gypsum, or recycled gypsum. Each type changes how much carbon and energy is used. The table below shows how these materials are different:

Making gypsum board uses less energy than making cement. It needs lower heat, so less carbon dioxide goes into the air. Using FGD gypsum or recycled gypsum makes the process even cleaner. Factories that use recycled gypsum can lower pollution by more than 40%. This saves resources and helps the planet.

MgO board is made from magnesium oxide, which comes from mining. Some factories use waste to make MgO board, but most use new materials. Making MgO board can use more energy than making gypsum board. Moving heavy MgO boards also adds more carbon to the air. But MgO boards last longer and need fewer replacements, which can help the environment over time.

Picking recycled or FGD gypsum helps builders lower harm to the earth. MgO board lasts a long time, but making it may use more resources.

Health & Safety

Both boards can change the air inside buildings and affect safety. Gypsum board is safe for most people. It does not let out bad gases when used right. Some boards have extra things added, but these do not usually hurt health. If gypsum board gets wet, mold can grow. Mold can cause breathing problems, especially for people with allergies.

MgO board stops mold and mildew from growing. This helps keep the air inside clean and safe. MgO board does not burn or make toxic smoke in a fire. This makes it a good pick for schools, hospitals, and homes. Some MgO boards may have a little chlorine or other chemicals. Good quality boards meet safety rules and do not let out harmful stuff.

• Gypsum board: Safe, but can get mold if it gets wet.

• MgO board: Stops mold, does not burn, and keeps air clean.

Builders should read labels and pick boards that meet health and safety rules. Both boards can make safe spaces if used the right way.

Installation

Ease of Use

Many builders look for the ease of installation when choosing wall boards. Gypsum board stands out for its simple process. Workers can cut it with a utility knife and snap it into place. Most people find it light enough to carry and lift. One person can often install gypsum board on a wall or ceiling without help. The tools needed are basic, such as a knife, tape measure, and screwdriver. This makes the ease of installation high for most projects.

Mgo board feels heavier and harder to cut. Workers need a saw with a diamond blade to make clean cuts. The board also needs special screws that resist corrosion. Two people may need to work together to lift and hold mgo board in place. The ease of installation drops when compared to gypsum board. However, some builders accept this because mgo board lasts longer and works better in tough spots.

Tip: For quick jobs or large projects, gypsum board offers the best ease of installation. Mgo board works better for jobs that need extra strength or water resistance.

Common Challenges

Both boards come with their own set of challenges during installation. Gypsum board can break or crumble at the edges if handled roughly. It does not do well in wet areas, so workers must keep it dry at all times. If the board gets wet, it may need to be replaced before finishing the job.

Mgo board creates dust when cut, which can bother workers. The board’s weight makes it hard to move, especially in tight spaces. Workers must use the right screws and tools to avoid damaging the board. Sometimes, mgo board can absorb moisture from the air before installation, which may cause warping if not stored properly.

A quick look at common issues:

• Gypsum board: Crumbling edges, water damage, easy to dent.

• Mgo board: Heavy, hard to cut, special fasteners needed, dust during cutting.

Workers should plan ahead and use the right tools for each board. Good storage and careful handling help avoid most problems.

Applications & Limitations

Where to Use Gypsum Board

Gypsum board fits many common applications in building projects. People often use it for interior walls and ceilings in homes, schools, and offices.
