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.

In everyday life, we sometimes encounter cases of homonyms. During casual conversation, when referring to people with the same name, we have to add prefixes or suffixes for clarification; otherwise, it becomes unclear who we’re talking about. This phenomenon isn’t unique to Chinese speakers—after frequent exchanges between Chinese and foreign literary and artistic works, the prevalence of names like Tom, Jimmy, and David in overseas media has led us to realize that this is a global challenge.
Application of Quick-Install Wall Panels in Public Building Renovation
In the previous article, we discussed material selection for quick‑install wall panels. The key is to stay true to your needs—not necessarily opting for the absolute best materials, but choosing what suits you most. Of course, if you’re rolling in cash and want it all, no one will object. In this piece, let’s talk about installing these panels. Today, renovating public buildings typically begins with removing the existing finishes, which are often ceramic tiles or painted walls. Over time, the surfaces accumulate layers of wear and tear, and seeing them can become increasingly frustrating. Renovation isn’t just about cosmetic makeovers; more often than not, it aims to refresh the mood of those who spend time inside.
Application of Quick-Install Wall Panels in Public Building Renovation (Material Selection)
Many public buildings are quite old and no longer meet current requirements, facing the need for renovation or remodeling. The construction materials used under the historical conditions of their time—such as ceramic tiles applied to walls as cladding panels or plasterboard suspended ceilings in common areas—now reveal drawbacks when viewed through a modern lens: wet‑process methods are time‑consuming and costly, and routine maintenance of overhead services is inconvenient. As a result, many owners prefer to renovate using prefabricated wall panels and ceilings, which allow ongoing operations during the upgrade by renovating one area at a time without disrupting daily business. This section introduces the application of quick‑install wall panels in building renovations.
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.
