Fire-resistant board for ventilation ducts It is a fire-resistant material specifically designed for ventilation or smoke-extraction ducts in construction projects. As a new type of green building material, it boasts high stability and is primarily composed of fibers, siliceous and calcareous minerals, and refractory materials. It contains abundant flame-retardant components and has a thermal conductivity significantly lower than that of glass, clay, and ordinary concrete. Its strength is more than twice that of conventional gypsum boards. This material features high fire resistance, zero pollution, long service life, and ease of installation, making it widely used in fire protection systems across various types of buildings. Below, we’ll introduce the product characteristics and application scope of ventilation duct fireproof panels:

　　I. Product Features of Fire-Resistant Boards for Ventilation Ducts:

　　1. Lightweight and high strength: The product features a special structural design that makes it significantly lighter than ordinary concrete and clay bricks, while also boasting high flexural strength. It is lightweight yet has twice the strength of conventional gypsum boards. In particular, when used as an external pressure smoke exhaust system or a smoke and exhaust system in construction projects, the ventilation duct fire-resistant board can fully leverage its advantages of high strength, light weight, excellent ductility, and strong seismic resistance.

　　2. Fire Resistance and Flame Retardancy: The product’s non-combustibility shall meet Class A standards. After installation, the fire-rated panels exhibit excellent stability, integrity, and fire resistance. In the event of a fire, the panels can effectively contain and isolate the blaze within the main ducts. Since the flame-retardant fiber material is inorganic, it is inherently non-combustible and will not release toxic gases even under high temperatures, providing an additional layer of protection for your health.

　　3. Easy to process: The product can be processed in any way (planed, sawn, nailed, drilled), offering more design flexibility.

　　4. Appropriate load-bearing capacity: The product has high strength and can withstand certain wind loads.

　　5. High Durability: The product is made of inorganic calcium silicate material, which is resistant to aging and weathering and boasts excellent mold- and corrosion-resistant properties. Even in the presence of water, it will not deform. It is a durable, high-performance building material whose normal service life can match that of various types of buildings.

　　6. Green building materials: Fire-resistant board for ventilation ducts Not only does it produce no pollution during the manufacturing process, but it also generates no hazardous waste. It is a new type of green building material that is completely pollution-free. It is non-radioactive and does not release harmful substances even when exposed to changes in ambient temperature and humidity conditions.

　　7. Economical and practical: The product features a thin profile and light weight, making pipeline construction more flexible, reducing the overall load on the pipeline, and effectively shortening the construction period.

　　II. Scope of Application for Fire-Resistant Boards for Ventilation Ducts:

　　Commonly used for self-supporting ductwork, workbenches, wall panels for interior and exterior building walls, fire-retardant coatings for steel columns and beams, raised access floors, indoor projects such as tunnels, home décor, and ceiling and partition walls in industrial and commercial applications. Construction companies, design firms, and contractors can select products based on the specific requirements of their projects. Fire-rated ductboard is a specialized fire-resistant material widely adopted in first- and second-tier cities across the country. Main specifications: 1220*2440*9, 12mm. If customers require other specifications, the manufacturer can provide cutting services or can also process custom-specification orders upon request.
