Gypsum Board System Q&A – Expert Answers
Q1: What raw materials are used to produce gypsum boards?
A1: The core material is made of 100% eco-friendly desulfurized gypsum. Through a unique foaming process, functional additives are precisely formulated to meet different performance requirements. The core is then laminated with high-quality, eco-friendly facer paper. This ensures the boards are free from formaldehyde, benzene, and phosphorus, making them a truly green and safe building material.
Q2: What is Nano Active Manganese?
A2: Nano Active Manganese is a high-tech catalyst with a nanoscale particle size of 10–20 nm, giving it exceptional catalytic activity. It can effectively decompose formaldehyde into harmless carbon dioxide and water. Since it functions as a catalyst, it does not participate in the chemical reaction itself, ensuring long-lasting performance without reduction or degradation over time.
Q3: Why can gypsum boards adsorb formaldehyde?
A3: Gypsum boards undergo a unique foaming process during production, resulting in a highly porous structure within the board core. The uniform and fine pores not only reduce the board’s weight and enhance its physical properties but also provide a “breathing” capability, allowing it to effectively adsorb certain harmful gases in the air and help regulate indoor humidity. However, simple adsorption alone is not enough—if formaldehyde is only absorbed and not actively decomposed, saturation can lead to a “desorption effect,” causing secondary pollution.
Q4: Should gaps be reserved between gypsum boards during installation? If so, how much?
A4: During installation, a gap of approximately 3 mm should be left between gypsum boards. The boards must be installed parallel to each other, with uniform gaps, and the edges should be free of cracks or broken pieces. For proper treatment of the gaps to prevent cracking, please refer to the Jason Joint Treatment System and the Jason Inside & Outside Corner Treatment System.
Q5: Why are measurement markings printed on the surface of gypsum boards?
A5: Measurement markings are primarily for the convenience of workers during installation. They help ensure proper alignment of the entire board, indicate the positions of the studs, and allow each self-tapping screw to be fixed in the optimal position, thereby enhancing the overall stability of the system.
Q6: Can gypsum boards be used outdoors?
A6: Generally, gypsum boards are not suitable for outdoor use. They are designed as interior wall and ceiling panels and are not intended for exterior environments. However, in some special construction scenarios, functional gypsum boards may be used—for example, the Jason Glass-Fiber Faced Water- and Fire-Resistant Board has been applied in the middle layer of ceiling installations.
Q7: Can light steel keel ceilings be used to create irregular shapes?
A7: Extremely complex shapes are not feasible, but standard curved ceilings and partition walls are generally achievable. Please refer to the Jason Curved Wall System for guidance.
Q8: Why should light steel keels be used for gypsum board ceilings and partition walls?
A8: Compared to traditional wooden keels, light steel keels are made from galvanized steel strips processed through cold rolling, making them lightweight, strong, and resistant to deformation. They also offer two major advantages over wood: moisture resistance and insect resistance. Even in humid environments, they are unlikely to rust, deform, or crack.
Q9: Is the Jason UBEST a gypsum board? How does it differ from regular gypsum boards?
A9: The Jason UBEST is essentially still a gypsum board. However, thanks to Jason’s independently developed special manufacturing process, its core strength and nail-holding capacity are comparable to those of wooden substrate boards. It can fully replace wooden substrate boards in construction, while retaining the inherent eco-friendly advantages of gypsum boards.
Q10: I want a ceiling design without a main light, but my ceiling height is only 2.5 meters. I’m worried it might feel cramped. What can I do?
A10: If the ceiling height is sufficient, a traditional suspended ceiling system can be used. For lower ceilings, a cassette keel ceiling system or even a seamless ceiling system is a perfect solution. These systems can reduce the actual ceiling thickness to within 5 cm, allowing a no-main-light design even in spaces with limited height.
Q11: Can gypsum boards be used for bathroom ceilings?
A11: Yes, they can. However, it is recommended to use gypsum boards with explicit water-resistant properties, such as Jason Water-Resistant Paper-Faced Gypsum Board.
Q12: Are gypsum boards environmentally friendly?
A12: Absolutely. Jason gypsum boards are made entirely from desulfurized gypsum, which is naturally free of formaldehyde, benzene, and phosphorus. No formaldehyde-containing additives are used during production, making gypsum boards truly zero-formaldehyde building materials.
Q13: What are lightweight building materials, and why should they be used?
A13: Lightweight building materials are materials that, while achieving the same construction volume and functional performance, have a lower self-weight. Extensive use of lightweight materials reduces the load on the building structure, effectively enhancing the building’s durability. For individual users, the main advantages are lower transportation costs and reduced overall usage expenses compared to heavier, non-lightweight materials.
Q14: Can tiles be installed on gypsum boards?
A14: Ordinary paper-faced gypsum boards are not suitable for tiling. However, Jason UBEST, a high-performance gypsum-fiber board, can be tiled and is suitable for lightweight partition walls with light steel keels in areas like kitchens and bathrooms where tiling is required.
