MgO board is special because it is naturally fireproof, does not burn, and fights mold and water.

Here is a table to help you see the main types of fire resistant sheathing:

Tip: Always look at the fire ratings and rules for each type before you pick a fire resistant sheathing board.

Why Fire Ratings Matter

You need to look at fire ratings and rules when you choose fire resistant sheathing. These ratings tell you how long a board can stop fire. They help you know if a product will work in a real fire. In tests, fire resistant sheathing boards like gypsum and calcium silicate did well, but MgO board did not always do as well. Adding steel sheathing made all boards better at stopping fire. This means how you put in fire resistant sheathing can change how well it works in a fire. Fire ratings and rules help you follow building codes and keep your building safe.

Fire Codes & Building Code Compliance

Key Fire Codes and Standards

You need to know the main fire safety codes before you choose fire resistant sheathing. These codes help you keep your building safe and meet building code compliance. Here are some of the most important fire safety rules and standards you should follow:

• The International Wildland-Urban Interface Code (IWUIC) sets rules for fire safety in areas with wildfire risks.

• SFM 12-7A-1 is a certification from the California State Fire Marshal for fire rated sheathing boards.

• UL 263 and ASTM E119 test the fire resistance rating of materials and check how well they hold up during a fire.

• ASTM E136 checks if a material is non-combustible.

• Local or state WUI codes often use the IWUIC as a base and change it for local fire risks.

You must follow these fire safety codes to make sure your fire resistant sheathing meets all fire safety rules.

Understanding UL and ASTM Ratings

You will see UL and ASTM ratings when you look at fire rated sheathing. These ratings show how well a product can stop fire. ASTM E119 is the main test for fire resistance rating in the United States. It checks how long fire resistant sheathing can keep fire from spreading. UL uses similar tests, so you can trust both ratings. In Canada, ULC 263 matches ASTM E119, so you get the same level of fire safety. When you see these ratings, you know your fire rated sheathing meets strict fire safety rules.

IBC Requirements for Sheathing

The International Building Code (IBC) gives clear rules for fire resistant sheathing in different building types. You must check the fire resistance rating for your project. Here is a table that shows what the IBC asks for:

If you do not follow these fire safety rules, you can face big problems. You might get fines, lawsuits, or have to fix your building.
