Mark had always been passionate about sustainable construction. As a contractor with over a decade of experience, he had worked with various materials—plywood, fiber cement, and gypsum board—but he was always searching for something better. When he took on a project to build an energy-efficient home in a coastal area, he knew he needed a material that could withstand moisture, fire, and mold. That’s when he discovered MgO sheathing.
The Search for a Reliable Building Material
Mark’s client, Sarah, wanted a home that was not only modern but also built to last. Living near the coast meant exposure to high humidity, heavy rain, and strong winds. Traditional materials often warped, absorbed moisture, or became a breeding ground for mold. Mark needed a durable solution, so he began researching alternative options.
Putting MgO Sheathing to the Test
Mark ordered a few sample boards to evaluate their performance. He was immediately impressed by the lightweight yet sturdy structure. Unlike gypsum boards that could crumble under pressure, MgO sheathing had a solid, cement-like feel while remaining easy to cut and install.
To see how it performed under extreme conditions, Mark exposed the samples to water for several days. Unlike plywood, which swelled, or fiber cement, which absorbed moisture, the MgO board remained intact. Even better, it showed no signs of mold or mildew growth.
Next, he put it through a fire test. Using a propane torch, he applied direct heat to the board. To his amazement, it didn’t burn or emit toxic fumes. This was a game-changer—especially for Sarah’s home, where fire safety was a top priority.
Convinced of its superior qualities, Mark recommended MgO sheathing for Sarah’s home. The installation process was seamless, saving both time and labor costs. Months later, when Sarah invited Mark over for a housewarming party, she was thrilled with the results. The walls were sturdy, the indoor air quality was excellent, and even during a recent storm, the structure held up without any damage.
