Why MgO Boards Hold An Edge Over Other Board Types

Magnesium Oxide (MgO) boards have gained significant popularity among businesses in the construction sector in the last few years. According to a market study released on June 17, 2020, the global market for magnesium oxide boards is estimated to rise to $2599.8 million by 2026 from $1828.3 million this year at a compound annual growth rate of 5.1 percent.


Ahead, we’ve conducted a thorough comparative analysis of MgO boards with other board types to uncover what’s causing the sharp increase in demand and value of Magnesium Oxide boards.


Resistance to Fire Damage


Both magnesium oxide board and calcium silicate boards are fire-resistant materials. However, in a fire emergency, a structure made of gypsum boards will start to burn at 200°C.


Resistance to Water Damage


In terms of waterproofing and resistance, magnesium oxide boards are the most reliable. Though calcium silicate boards are waterproof too, they are less resistant to water damage compared to MgO boards. On the other hand, gypsum boards aren’t recommended for construction purposes because of no water resistance.

Physical Properties

  • Density


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.


Impact and Bending Strength

Since MgO boards comprise of more durable glass fiber offering higher strength, they are more resistant to impact and bending than calcium silicate and gypsum boards.


Thermal Conductivity and Expansion




When it comes to thermal conductivity and expansion, all three board types react similarly because of their inorganic nature.
