Fireproof boards are a broad category that encompasses various fire-resistant materials, such as calcium silicate boards and magnesium oxide boards. Glass-magnesium fireproof boards are a subcategory of fireproof boards and belong to the family of inorganic fireproof panels.

　　Categorical relationship: Fireproof board is a broad concept that encompasses various fire‑resistant materials, such as calcium silicate boards and magnesium oxide boards; glass‑magnesium fireproof board is a subclass of fireproof board and falls under the category of inorganic fireproof boards.

　　Material and Composition: Glass-magnesium fireproof boards use magnesium oxide, magnesium chloride, and alkali-resistant fiberglass cloth as their primary raw materials, whereas other fireproof boards may employ different substrates—such as density board or particleboard—or be finished with a fire-retardant surface layer.

　　Performance focus: Glass-magnesium fireproof boards emphasize a high fire‑resistance rating (up to Class A1), superior high‑temperature resistance, water and moisture resistance, and environmental friendliness; by contrast, standard fireproof boards may prioritize decorative appeal or short‑term flame retardancy, with relatively lower fire‑protection performance.

　　Glass-magnesium fireproof boards typically offer advantages such as light weight, high strength, and ease of sawing and nailing, making them suitable for applications like interior partitions and suspended ceilings. Meanwhile, “fireproof board” is a general term that encompasses a broader range of products, including decorative fire-resistant materials.
