Comparison to Traditional Materials

You may wonder how MgO boards compare to other common materials. Magnesium oxide boards are highly resistant to flames. They carry top ratings from groups like ATSM and the International Code Council. Traditional materials, such as gypsum board or plywood, do not match this level of fire resistance. OSB burns much faster and cannot protect your home as long as MgO boards. Gypsum board may slow down a fire, but it does not last as long as magnesium oxide. When you choose MgO boards, you get a fire resistant product that outperforms most other options. This makes MgO boards a smart choice for anyone who wants better safety and peace of mind.
