Fire resistance performance of common fireproof boards and glass wool

In the construction and decoration industry, the selection of fire-resistant materials is crucial. Among these, fire-resistant boards come in various types, each with its own advantages, while glass wool, as a commonly used material, has also attracted considerable attention. Below, we will discuss in detail common fire-resistant boards and whether glass wool is fire-resistant.

I. Common Fireproof Boards

Calcium silicate board

• Features: High strength, fire resistance, moisture resistance, heat insulation, and corrosion resistance. Calcium silicate board has excellent fire resistance; it does not burn at high temperatures and does not produce toxic fumes.

• Applications: Widely used in building partitions, ceilings, ventilation ducts, and other parts.

Fiber reinforced cement board

• Features: Made with cement as the main binder and with the addition of an appropriate amount of fiber reinforcement. It features fire resistance, water resistance, moisture resistance, high strength, and good durability.

• Applications: Can be used on indoor and outdoor walls, roofs, floors, etc.

Mineral wool board

• Features: Made primarily of mineral fiber wool, it possesses sound absorption, heat insulation, and fire resistance properties. Mineral wool boards typically have a fire rating of Class A, meaning they are non-combustible and effectively prevent the spread of fire.

• Applications: Commonly used for ceilings in public places such as offices, shopping malls, and hospitals.

Fireproof gypsum board

• Features: Fire-retardant materials are added to gypsum board, improving its fire resistance. Fire-retardant gypsum board has advantages such as being lightweight, high-strength, fire-resistant, sound-insulating, and heat-insulating.

• Applications: Primarily used in building partitions, ceilings, and other similar components.

Magnesium oxide board

• Features: Made of magnesium oxide, magnesium chloride, and other materials, it is fireproof, waterproof, moisture-proof, corrosion-resistant, non-toxic, and odorless. The fire resistance of the magnesium oxide board reaches A1 level, and it maintains structural stability at high temperatures.

• Applications: Suitable for interior and exterior decoration, fireproof partitions, ventilation ducts, and other fields.

II. Fire-resistant properties of glass wool

Glass wool is an inorganic fiber material, its main component being glass fiber. Glass wool itself is non-combustible, and in the event of a fire, it can act as insulation, preventing the spread of fire. Generally, glass wool's fire resistance rating meets the Class A non-combustible material standard.
