Key Takeaways
There are many strong fire resistant materials besides gypsum board. Some examples are fiber cement, MGO, and calcium silicate boards. These materials are all good at stopping fire. Some materials can last up to two hours in a fire. This gives you more time to stay safe. When you pick a fire resistant board, think about how long it will last. Also think about the price and how easy it is to put in. Some boards can also stop water, mold, and bugs. This makes them great for wet or damp places. Using fire resistant materials helps keep your home safe. It also helps you feel calm for many years.
1. Fiber Cement Board
Features
Fiber cement board gives you a strong and reliable wall or ceiling option. Manufacturers make it by mixing cement, sand, and cellulose fibers. This combination creates a dense, solid board that resists damage from water, insects, and mold. You can use fiber cement boards both inside and outside your home. Many builders choose this material for its toughness and long life. Some well-known products in this category include boards similar to Hardie Board or HardiPanel.
Fire Rating
Fiber cement board stands out for its fire resistance. Most fiber cement boards carry a Class A fire rating. This means the board will not catch fire easily and can slow down the spread of flames. In many cases, you can get up to a one-hour fire rating when you install it correctly. This gives you extra time to react in case of a fire.
Pros
High fire resistance
Strong and durable
Resists water, mold, and insects
Works for both indoor and outdoor projects
Low maintenance
Tip: Fiber cement board can last for decades with proper care.
Cons
Heavier than gypsum board

These panels work well in basements and garages where you want extra fire and moisture protection. You can also use them as a base for tile or as a wall covering in commercial buildings. Glass mat panels help you create safer and longer-lasting spaces.
8. Modern Stucco
Features
Modern stucco gives you a strong and fire-resistant finish for your home. You get this material when you mix Portland cement, sand, and lime. These ingredients create a hard surface that can stand up to heat and flames. You can apply stucco over many surfaces, such as concrete, brick, or wood with a proper base. Modern stucco systems often include layers for extra strength and insulation. Some systems use mineral wool insulation, which does not burn. You can choose different textures and colors to match your style.
Tip: Modern stucco works well for both new homes and remodeling projects.
Fire Rating
Modern stucco systems have passed tough fire resistance tests like ASTM E119, NFPA 268, and NFPA 285. When you follow the manufacturer’s instructions, stucco meets important building code rules for fire safety. Some systems use non-combustible insulation to make them even safer. Most codes do not give a specific number of hours for fire resistance, but these systems slow down the spread of fire and protect your home.
Pros
High fire resistance
Durable and long-lasting
Resists mold, insects, and weather
Many color and texture options
Works for inside and outside walls
