Fire Resistant Board Fire Resistant Boards, also known as FR Boards, are specially designed gypsum boards that provide excellent fire protection due to their unique core composition. Made from aerated gypsum, glass fiber, and additives, these boards have low thermal conductivity and high heat absorption, ensuring resistance to fire for 60 to 120 minutes, depending on thickness and installation. The strong pink-colored paper liners further enhance durability and fire resistance. Fire-resistant boards are widely used in both residential and commercial applications, including kitchens, server rooms, inverter rooms, and office spaces. Their easy installation, eco-friendly composition, and superior durability make them an essential choice for fire-prone areas in modern construction.
