Understanding Fire Resistant Wallboards
What Are Fire Resistant Wallboards?
Fire resistant wallboards are special materials that help stop fires. They are important for keeping homes and buildings safe from fire. These wallboards are made from materials that do not burn easily. Instead of catching fire, they block flames for a certain amount of time. For instance, some wallboards can stop fire for up to two hours, depending on their type.
Unlike regular wall materials, fire-resistant wallboards have special features. These features make them perfect for areas needing extra fire safety. They are often used in stairways, hallways, and shared walls in offices. Using these wallboards helps meet fire safety rules and keeps people safer.
How Fire Resistant Wallboards Work
The fire-stopping ability of these wallboards comes from what they are made of. Wallboards made with gypsum, like Type X or Type C drywall, hold water inside. When fire heats them, the water turns to steam slowly. This slows down heat and keeps flames from spreading. Some wallboards also have things like fiberglass or vermiculite to make them even better at stopping fire.
Some wallboards grow thicker when heated, forming a shield to protect structures. This is very useful in big buildings where materials must handle high heat for a long time. Special coatings, called intumescent coatings, are added to some wallboards. These coatings expand with heat, adding more protection against fire.
Common Applications
Fire resistant wallboards are used in many places to meet fire safety rules. In offices, they are put in walls, ceilings, and dividers to stop fire. In homes, they are used in garages, basements, and utility rooms where fires might start.
You can also find these wallboards in schools, hospitals, and theaters. Since they don’t burn easily, they help protect people and reduce damage. As safety rules change, more people use fire-resistant materials to create safer spaces for everyone.
Types of Fire Resistant Wallboards
Fire Rated Gypsum Board
Fire rated gypsum board is a popular fire-resistant material. It has a gypsum core between two paper layers. Fiberglass and other additives make it resist fire better. When heated, the gypsum releases water vapor. This slows down flames and keeps fire from spreading. It is used in homes and offices for fire-rated walls.
Different thicknesses give different fire resistance times. A 12.7 mm board lasts about 51 minutes. A 15.9 mm board lasts around 52 minutes. Two layers of gypsum board can last up to 79 minutes. Below is a chart showing fire resistance times for various types:
This board is great for walls, ceilings, and partitions needing fire safety.
