Table of Contents
Have you been looking for options other than MgO boards lately? We’re in the same boat because chloride leakage is possible if the boards come in contact with water.
And guess what?
We found a hidden gem that can solve this problem and have other benefits. Drum rolls as we introduce the Magnesium Oxide Sulphate boards to you all. These boards have unmatchable fire-resistance and moisture-resistance abilities.
Moreover, they have high impact strength and are sustainable. So, what’s the wait? Let’s get into the topic to know about MSO boards.
But first, take a quick overview of MgO boards.
MgO Boards: A Quick Overview
Magnesium Oxide boards or MgO boards are evergreen and sustainable alternatives to traditional building materials. The substituents are abundant in nature and have multiple indoor and outdoor construction applications. MgO boards are fire-resistant, water-resistant, and mold-resistant. Besides this, the building material has high strength and durability.
Moreover, the production and manufacturing process has fewer emissions and a low carbon footprint. On top of that, MgO boards are recyclable. Noise insulation and all these properties make MgO boards a top pick for residential and commercial buildings.
Here are the potential applications of MgO boards in commercial and residential buildings:
- Ceiling
- Wall panels
- Wall cladding
- Flooring
- Sub-flooring
- Partitions
- Tilebacking
- Furniture and duct-covering
However, everything comes with certain drawbacks. MgO boards have the following limitations:
- High cost
- Difficult to install
- Limited availability
- Moisture sensitivity
- Leaching chloride
For all the above reasons, exploring the alternatives to MgO boards is imperative. The best part is that we have one for you.
Alternative to MgO Boards – Magnesium Oxide Sulfate (MOS) Boards
Magnesium Oxide Sulfate boards (MOS) are a top alternative to MgO boards.
The only difference is the use of adhesive material, chloride in MgO boards, and magnesium sulfate (MgSO4) in MOS boards.
Both boards have good moisture-resistant ability, but MgO boards each chloride when exposed to water for a long time. However, the MOS board does not leach any harmful chemicals. MOS holds the upper hand because of its improved impact and flexural strength, enhancing its stability and performance. Moreover, due to its constituents, MOS boards do not experience the halogen backfire phenomenon.

Key Specifications of MOS Boards
Here’s a list of critical properties you might be looking for when choosing building materials. These key features make MOS boards stand out.
1. Fire-resistant
One of the primary features of MOS boards is their superior fire resistance, which is an important parameter for a building material.
One layer of MSO board can withstand fire for 60–90 minutes without releasing harmful chemicals. Moreover, there is no flame at 800°C and no burn at 1200°C, which shows high non-combustibility of MOS boards.
2. Moisture-resistant
Good moisture-absorbing properties are also considered when choosing building materials. MOS boards possess this property, too. Although MgO boards possess the same property, they’re notorious for chloride leakage.
However, MOS boards are different. This is why they are suitable for areas with high moisture content, such as washrooms, kitchens, and basements.
3. Safe for Health
As mentioned, MSO boards do not emit harmful fumes or materials when exposed to high temperatures. Moreover, there is no by-product when the material comes in contact with water. Therefore, MSO boards are safe for health.
4. High Strength and Durability
MOS boards are sturdy materials that can withstand high pressure. Therefore, they are suitable for rush areas as well. And they can last long without wearing and tearing.

5. Mold and Termite Resistance
MOS boards are not a welcoming host for mold and termites, thanks to the unique blend of materials that made them. The termite and mold resistance also increases their life span.
What’s more?
MSO boards are also fungus-resistant.
6. Easy-to-Install
MOS boards weigh relatively less than MgO boards. Their little to no weight compared to traditional building materials makes cutting, drilling, and transportation easy.
7. Eco-friendly Buiding Material
Similar to MgO boards, MSO boards are also environmentally material. The constituents, production, and manufacturing processes are similar. Only the sulfate replaces the chloride as an adhesive material. Therefore, MSO boards are also an eco-friendly alternative to MgO boards.

8. Versatile Applications
MSO boards have a wide range of applications, and the primary reasons are:
- Top-notch fire-resistance
- High water resistance
- High strength
- Durability
- Safe for health
Due to all these benefits, MSO boards are more suitable for schools, hospitals, and offices. They can also be used as decorative materials to make your space spacious and comfy.
Well, the product specifications are unmatchable. But there is a downside, too. MSO boards are expensive.
