Fire-resistant board for ventilation ducts It is a fire-resistant material specifically designed for ventilation or smoke-exhaust ducts used in construction projects. In fact, the fire-resistant duct boards we’re talking about here are a new type of green building material characterized by high stability. Next, let’s take a brief look at some basic introductions to fire-resistant duct boards for ventilation systems.

　　The main components of the ventilation duct fireproof board consist of fibers, siliceous and calcareous minerals, and refractory materials. It is rich in flame-retardant substances 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 product features high fire resistance, zero pollution, long service life, and easy installation. The ventilation duct fireproof board is also widely used in fire protection systems for various types of buildings. The product is primarily made from high-quality fire-resistant quartz powder and flame-retardant minerals (mica, perlite), supplemented by cement and various additives. It is reinforced with multiple mineral fibers, including superior fire-resistant composite fibers. The board is manufactured using advanced production processes, including special techniques such as high pressure, high temperature, and steam curing. Due to its unique structural composition, Fire-resistant board for ventilation ducts It is much lighter than ordinary concrete and clay bricks and boasts higher flexural strength; its weight is light, and its strength is more than twice that of conventional gypsum boards. Moreover, especially when duct fireboards are used in this project as smoke exhaust systems or external-pressure smoke exhaust systems, their strengths—high strength, light weight, excellent ductility, and strong seismic resistance—can be fully leveraged.

　　The fire-resistant board for ventilation ducts meets the Class A standard for non-combustibility. After installation, the fire-resistant board exhibits excellent stability and integrity, as well as superior fire resistance. In the event of a fire, it can naturally contain the initial blaze within the duct, effectively isolating the fire. Since the flame-retardant fiber material is inorganic, it neither burns nor emits toxic gases even under high temperatures. Thus, it provides an additional layer of protection for your health—a true embodiment of the preventive approach, where prevention is better than firefighting! The fire-resistant board for ductwork can be freely processed (planed, sawn, nailed, or drilled), offering greater flexibility in design solutions! It boasts high strength and can withstand certain wind loads. That’s all I’d like to share with you today. Fire-resistant board for ventilation ducts It is also primarily composed of inorganic calcium-silicate materials, which are resistant to aging and weathering and exhibit excellent mold- and corrosion-resistant properties. Even under wet conditions, it remains dimensionally stable, making it a durable, high-performance building material whose typical service life can match that of various structures. Consequently, the fire-resistant panels for ventilation ducts are not only pollution-free—producing no hazardous waste during manufacturing—but also represent a new type of green building material that is zero-pollution, non-radioactive, and does not release harmful substances due to changes in ambient temperature or humidity. In particular, their thinness and light weight make duct installation more flexible, reduce the overall load on the ductwork, and effectively shorten the construction period.
