What is air duct fire board?

Air duct fireproof board is a kind of fireproof material specially used for ventilation or smoke exhaust duct in construction projects. Huachengxing air duct fireproof board is a new green building material with high stability. The main composition is composed of fiber, siliceous calcium mineral and refractory material, and its flame retardant material is rich, and its thermal conductivity is lower than that of glass, clay and ordinary concrete. In the strength is much higher than the traditional plasterboard, with high fire grade, no pollution, long life, convenient construction and other characteristics, is widely used in a variety of building fire prevention system.


Introduction to Products

I.Production process

 Huachengxing Air Duct Fireproof Board is manufactured using high-grade fire-resistant quartz powder, flame-retardant minerals (mica, perlite), cement, and various additives as raw materials. It is reinforced with premium refractory composite fibers and other mineral fibers. Through advanced production techniques, the board is molded and then specially treated under high pressure, high temperature, and steam curing processes to ensure superior performance.

Ii. Product features:

  1. Lightweight and High Strength: The Huachengxing air duct fire board features a unique structure that is significantly lighter than ordinary concrete or clay bricks, yet offers high flexural strength. It is not only lightweight but also stronger than traditional plasterboards of equivalent thickness. Particularly when used in exhaust systems under external pressure or in air exhaust and smoke extraction systems, it demonstrates excellent characteristics such as high strength, light weight, good ductility, and strong earthquake resistance.

  2. Fire Retardant: Huachengxing air duct fire board meets the Class A standard for non-combustibility. Once installed, it provides superior stability and integrity, offering enhanced fire resistance. In the event of a fire, it effectively contains the flames within the initial pipeline section, ensuring proper isolation. Composed of inorganic flame-retardant fiber materials, the board does not ignite or emit toxic gases under high temperatures, providing added safety. This aligns with the fire safety principle of "prevention first, where prevention outweighs rescue."

  3. Easy to Process: Huachengxing air duct fire board can be easily processed (planed, sawed, nailed, drilled), allowing for greater flexibility in design solutions.

  4. Load-Bearing Suitability: The high strength of the air duct fire board enables it to withstand certain wind loads.

  5. High Durability: Made from inorganic silica-calcium materials, the air duct fire board is resistant to aging, weathering, mold, and corrosion. It maintains structural integrity even under humid conditions and does not easily deform. As a durable and high-performance building material, its normal service life is compatible with that of various building structures.

  6. Eco-Friendly Building Material: The production process of the air duct fire board is pollution-free and generates no hazardous waste. It is a new type of environmentally friendly building material, free from radioactivity and harmful substances, even under varying environmental conditions of temperature and humidity.

  7. Cost-Effective and Practical: The thin profile and lightweight nature of Hua Cheng Xing air duct fire board enhance flexibility in pipeline construction, reduce overall load, and effectively shorten construction timelines. 

Iii. Scope of application

It is commonly used in self-supporting air ducts, workbenches, interior and exterior building walls, fire cladding for steel columns and beams, interior linings for raised floors and tunnels, home renovations, and ceilings and partition walls in industrial and commercial projects. Construction units, designers, and contractors can select this product according to the specific requirements of their projects.

Huachengxing air duct fire board is a specialized fireproof material and has been widely adopted in major first- and second-tier cities such as Beijing, Shijiazhuang, Hohhot, Baotou, Tianjin, Shanghai, Guangzhou, Xi'an, and Dalian.

Main specifications: 1220×2440×9mm, 12mm
If customers require other sizes, the company can cut them accordingly. Special specifications can also be custom-processed upon request.

Iv. Installation method

Self-supporting Fireproof Board Air Duct:
The structure of the self-supporting fireproof board air duct is illustrated in Figure 1, with a detailed enlarged view of its corner joint provided in Figure 2.

Fireproof Cladding for Metal Air Ducts:
The structure of a metal air duct with external fireproof board cladding is shown in Figure 3, and a detailed view of the joint is provided in Figure 4.
A U-shaped light-gauge steel channel is fixed to the exterior of the metal duct, and the fireproof board is then attached to this steel framework.

 

Plate Cutting and Forming:

The four wall panels of a rectangular fireproof board air duct shall be cut according to the construction drawings, duct dimensions, and plate thickness. This includes the plates required for duct bends and sections with diameter changes.

Plate Specifications:

  • Size: 2440 mm × 1220 mm

  • Thickness: 9 mm, 12 mm, or 15 mm

Typically, each duct section is made 1220 mm long based on the plate width. When the duct length is ≤ 1220 mm, or the sum of its two side lengths is ≤ 1220 mm, the duct can be fabricated along the 2440 mm length of the plate to reduce the number of joints.

Splicing of duct panels should be avoided where possible. When splicing is necessary, it shall comply with the requirements shown in Figure 5, and reinforced measures shall be applied at the spliced sections of the duct.
