What is Magnesium Oxide

Magnesium Oxide (MgO) is a high-performance building material that combines strength, durability, and ease of installation in one streamlined solution. Cemrock MgO boards are composed primarily of inorganic materials, reinforced with layers of glass fiber mesh, and engineered to deliver exceptional fire resistance, sound absorption, and structural integrity.

Speed & Ease of Installation

Cemrock MgO boards install efficiently, often eliminating the need for multiple trades. Their lightweight and durable design simplifies handling and accelerates project timelines.

Inherent Strength

The proprietary design of Cemrock MgO boards includes a layered mesh reinforcement, adding to their structural value and making them a dependable choice for demanding projects.

Sound Absorption

Cemrock boards contribute to achieving high STC and IIC sound ratings as part of sound-tested assemblies, reducing the need for additional sound mats or layers.

Quality Assurance

Cemrock MgO boards are manufactured under stringent quality control standards, ensuring consistent performance and reliability across all applications.

Fire Resistance

Inherently fire-resistant throughout, Cemrock MgO boards are suitable for fire-rated wall, floor, and ceiling assemblies, providing reliable safety for a variety of applications.

Optimize Material & Labor Costs

Cemrock boards offer high-performing solutions that may reduce the need for additional materials and trades, saving time and money while maintaining superior results.

Durability

Cemrock boards are built to withstand jobsite conditions, resist moisture, and maintain their integrity without warping, expanding, or delaminating—issues commonly faced with traditional wood panels.
