Application of Silicate Fireproof Board in Smoke Control System
According to the national building standard atlas "Selection and Installation of Smoke Control System Equipment and Components" 22K311-5, five types of galvanized steel plate + silicate fireproof board + rock wool cladding structures are provided, which include fire resistance performance from 40 minutes to 180 minutes. It is basically applicable to the use of smoke control ducts in any environment. The following are the characteristics of silicate fireproof board in the system:
- High Fire Resistance LimitThe silicate fireproof board is mainly composed of inorganic materials, possessing excellent high-temperature resistance. In the event of a fire, it can maintain structural integrity for a long time, providing valuable time for personnel evacuation and firefighting rescue. Many high-quality silicate fireproof boards can easily achieve a fire resistance limit of 1 to 4 hours, fully meeting the strict requirements for duct fire resistance in various buildings. For example, in the smoke control duct system of high-rise buildings, using silicate fireproof board for cladding can effectively prevent the spread of fire through the ducts, ensuring the fire safety of the entire building.
- Non-combustible and Low SmokeThis fireproof board is made of non-combustible materials, which will not burn and produce open flames during a fire, preventing the further spread of the fire. At the same time, the amount of smoke produced at high temperatures is extremely low, and the harmful substances in the smoke are few, reducing harm to the respiratory tract of personnel and lowering the risk of smoke suffocation during a fire, providing a relatively clear escape environment for trapped individuals.
- High Strength and StabilityIt has high strength and good stability, capable of withstanding the weight of the duct itself, internal air pressure, and various external forces during normal use, making it resistant to deformation, cracking, and other issues. Even after long-term exposure to wind, sun, and rain, it can still maintain its original physical properties, ensuring the long-term reliability of the duct cladding system.
- High Dimensional AccuracyThe silicate fireproof board produced in factories has high dimensional accuracy and good flatness. This allows for tight splicing between boards during duct cladding construction, reducing gaps and improving overall fireproofing and sealing performance. At the same time, precise dimensions also facilitate cutting and installation by construction personnel, improving construction efficiency and reducing costs.
- Green and Environmentally Friendly MaterialThe raw materials used in silicate fireproof boards are mostly natural minerals, free from harmful chemicals such as formaldehyde and benzene, and do not cause environmental pollution during production, use, and disposal. For modern buildings that pursue green and environmentally friendly practices, this characteristic makes it an ideal choice for duct cladding.
- RecyclableSome silicate fireproof boards have recyclable properties. When buildings are renovated or demolished, the discarded fireproof boards can be recycled and reprocessed, reducing the generation of construction waste and aligning with sustainable development principles.
- Lightweight and Easy to InstallCompared to some traditional duct cladding materials, silicate fireproof boards are lighter, making them easy for construction personnel to handle and install. On construction sites, boards can be easily cut and drilled with simple tools, significantly shortening the construction period.

The Supporting Role in Wallboard Systems: Metal Trim Strips—Essential Yet Often Overlooked
Let’s start with the conclusion: when choosing decorative wall panels, our attention often focuses on the panel itself—whether it features wood grain, stone texture, or fabric patterns; whether the color palette leans toward light tones or darker shades; and how different colors can be coordinated. Meanwhile, metal trims used to cover joint gaps or corner transitions are easily overlooked, resulting in a final outcome that falls short of expectations. Why does this happen? Consider this scenario: in large‑area spaces like public corridors where wall panels are installed, if exposed trim strips are used, our gaze tends to be drawn to those strips, visibly fragmenting the wall’s overall cohesion. In essence, we end up noticing only the trim and overlooking the panels themselves.
Today, in many public buildings—such as gymnasiums, exhibition halls, underground spaces, and even some schools—observant visitors may notice that the walls and ceilings are fitted with panels riddled with tiny perforations. Upon inquiry, it becomes clear that these perforated panels possess a remarkable property: they can effectively “absorb” noise.
Precautions for Installing Calcium Silicate Board Ceilings
Although calcium silicate boards are now readily available in major building‑materials markets, many construction workers—especially those accustomed to working with gypsum board—still harbor doubts about installing ceiling systems using this material. They wonder whether their established techniques are suitable for calcium silicate boards. This article aims to clarify the issue; as for whether everyone will fully understand it, frankly, we’re not entirely sure ourselves. So let’s put it this way: we’ll explain it, and you can take it from there.
Introduction to the Method of Exposed-Frame Suspended Ceilings
What is an exposed‑grid ceiling? This is the common term people use, but why is it called that? As the name suggests, it refers to a ceiling construction in which the suspension grid members are left visible. It falls under the category of panel ceilings—this distinction is made relative to solid‑board ceilings. The decorative panels rest within the grid framework, with the exposed grid and the panels serving as decorative elements that together create the overall aesthetic. From a construction standpoint, an exposed‑grid ceiling is an assembly‑type system.
