OSB is combustible, susceptible to moisture damage, and contains formaldehyde-based binders. MagSheathing™ beats OSB on fire safety, moisture resistance, mold resistance, and environmental impact — while matching it for structural sheathing and subflooring applications.
Standard drywall is not suitable for wet areas, exterior use, or high-humidity environments. MagSheathing™ replaces drywall wherever moisture, fire, or durability is a concern — with superior performance in every category.
Cement board is heavy, brittle, and environmentally costly to produce. MagSheathing™ is lighter, more flexible, and eco-friendly — providing equivalent or better moisture and tile-backer performance without the weight penalty.
