MgO panels outperform wood and gypsum sheathing in durability and weather resistance. Each panel is manufactured from MgO cement that commonly withstands:
- Extreme temperatures, freeze/thaw cycles, and direct UV exposure – for several months during open-air construction
- Impact from tools, foot traffic, and equipment
- Prolonged exposure to wind, rain, snow, and humidity
Built for Harsh Environments
Where traditional sheathing products may warp, swell, delaminate, or break down under tough conditions, MgO panels retain their integrity and continue performing – giving your project longer-lasting results with fewer delays or repairs.
Install in Any Weather
- No curing time needed – unlike gypsum concrete
- Install rain or shine, allowing your team to stay on schedule
- Fewer jobsite delays due to material degradation during adverse conditions
Whether you’re working in humid bathrooms, busy kitchens, wet basements, or exposed exterior walls, MgO panels deliver strength, stability, and peace of mind. Mold- and mildew-resistant by nature, these panels stand up to moisture and protect what matters most – your build, your timeline, and your investment.
Abuse Resistance
Jobsite-tough and built to last, MgO panels resist impacts, abrasions, and everyday abuse. From the warehouse to the worksite, these panels are designed to handle real-world conditions without cracking, chipping, or deforming.
Proven Impact Performance
In laboratory testing and jobsite demonstrations, many MgO panels sustain no significant damage when struck by sharp metal objects such as hammers and drills. In practical terms, that means:
- Panels won’t crack or chip if tools are dropped during install.
- No damage from scuffs, scrapes, or dents caused by workers or materials bumping against surfaces.
- Unlike gypsum panels with paper facers that tear easily, most MgO panels are a single-layer cement panel – no facers to peel, no laminates to bubble or delaminate.
These characteristics minimize the need for repairs during construction and contribute to faster job completion and reduced material waste.
Corrosion Resistance
Modern MgO panels perform comparably to conventional sheathing products in terms of corrosion resistance when properly formulated and installed. The MgO building products industry recently developed corrosion resistance standards and testing to provide clear evidence of qualifying panels that pose no significant risk of corrosion. Strong quality control measures by the MgO panel manufacturer and installer adherence to manufacturer’s guidelines further reduce the risk of corrosion.
