FAQ

Q: What is magnesium oxide used for in construction?

A: MGO board is used in place of traditional gypsum drywall. It is also used in various other construction applications such as fascias, soffit, wall sheathing and also as a tile backing material. It's not paperfaced and is available in a range of sizes to suit the application.

Q: What is the difference between magnesium oxide board and gypsum board?

A: MgO board comprises of a glass-fiber that offers higher durability and low density, making these boards extremely light-weighted, but powerful. In contrast, calcium silicate and gypsum boards are made of shorter fibers, which means they can only offer more strength at a higher density or weight.

Q: Is magnesium oxide board waterproof?

A: The boards are still structural and dimensionally stable even when wet. They do not swell, warp, or delaminate. They even protect against moisture when underneath basement flooring boards. It is essential to note that MgO boards are moisture and water resistant but not waterproof.

Q: What is the purpose of magnesium oxide?

A: Magnesium oxide may be used for different reasons. Some people use it as an antacid to relieve heartburn, sour stomach, or acid indigestion. Magnesium oxide also may be used as a laxative for short-term, rapid emptying of the bowel (before surgery, for example). It should not be used repeatedly.

Q: What are magnesium oxide panels?

A: MgO panels are cementitious panels that are primarily made of inorganic materials reinforced with layers of glass fiber mesh. EXACOR® MgO panels are manufactured to provide a streamlined solution for strength, fire resistance and sound performance.

Q: Is MgO board structural?

A: When compared to wood-based products, MgO panels offer significant improvements in fire resistance, structural performance, and overall durability. Furthermore, MgO panels exhibit greater mold resistance and remain dimensionally stable when exposed to moisture.

Q: How thick is magnesium oxide board?

A: Description - Magnesium Oxide Boards are the most eco-friendly multi-purpose building panels. This 12mm (1/2 inch) thick sheet is most commonly used as walls and ceilings.

Q: Can you paint a magnesium oxide board?

A: Magnesium Oxide (MgO) boards are breathable and a characteristic of this property is a high suction. Prior to painting, plastering or tiling, the boards should be coated on receiving faces and edges with an acrylic based primer - applied in line with the manufacturers guidance for use.

Q: What happens when you mix magnesium oxide with water?

A: When magnesium oxide is dissolved in water, magnesium hydroxide is formed.

Q: How is magnesium oxide used in construction?

A: Magnesium oxide, more commonly called magnesia, is a mineral that when used as part of a cement mixture and cast into thin cement panels under proper curing procedures and practices can be used in residential and commercial building construction.
