Choosing a ceiling, it's important to break away from concepts.

In the current decorative ceiling industry, metal ceilings are relatively simple, with more emphasis on surface treatment processes rather than material differences. Non-metal ceilings are far more complex. Just considering the materials, there are mineral wool, calcium silicate (fiber cement), fiberglass, gypsum, rock wool, etc. Due to the different properties of the materials, the advantages and disadvantages of ceilings made from different materials are equally obvious. Many customers feel at a loss when faced with such a wide variety of non-metal ceilings, unsure of how to choose. Of course, there are also many manufacturers in this industry who come from a marketing background, skilled at creating new terms and concepts, which makes customers unfamiliar with the products even more confused.

This short article cannot solve all your problems, but it hopes to point out a direction or another way of thinking when you are confused, rather than making you even more confused.

Apart from the materials of non-metal ceilings, their installation methods are nothing more than exposed and concealed frames; semi-exposed and semi-concealed can be classified as mixed or pieced together.

Let's talk about exposed frames first. The official term is an installation method where the furring strips are exposed. This type of ceiling is common. Depending on the treatment of the ceiling edges, the ceiling can be divided into flat and stepped types. For flat ceilings, the requirements for the furring strips are high, and through furring strips should be used as much as possible. This way, the formed surface of the furring strips is on the same horizontal plane, and after placing the flat ceiling, the gaps are not obvious. For stepped ceilings, overlapping furring strips can be used. Even if there is a height difference in the formed surface of the furring strips due to the thickness of the furring strips, the drooping of the stepped edge can hide this defect.

Next, let's talk about concealed frames. Compared with exposed frames, it naturally means that the furring strips are hidden. This installation method is more selective about materials. Although there are many non-metal materials, mineral wool, rock wool, or fiberglass are preferred for concealed frames. Other materials can also be used, but it is not recommended. Because whether T-shaped or Z-shaped furring strips are used for concealed frames, side grooves will be involved, and there will be higher requirements for the thickness of the ceiling panels. The panels need to be thicker, and naturally, the lower the density, the safer. For materials such as gypsum and calcium silicate boards, if they are to be made into concealed frames, the thickness generally needs to reach 15mm or 20mm, and the weight per square meter is more than 10 kg. The general ceiling height is around 2.5 meters. The stability of the side slot fixing method is inherently inferior to the interlocking structure of the exposed frame. If this thing falls, it's no joke. Therefore, although hard inorganic materials can also be grooved to make concealed frames, from a safety perspective, choosing mineral wool, rock wool, or fiberglass is still better at present, unless a more stable concealed frame structure appears.

Once we have determined the installation method we want, choosing the material becomes much easier.

For exposed frames, if it is a standard specification of 600*600mm, any material is fine. When selecting, we only need to look at what we care most about: fire resistance according to the non-combustible level; calcium silicate board, decorative gypsum board, and rock wool board are superior to fiberglass board and mineral wool board; moisture resistance, cotton materials are inferior to inorganic hard materials; sound absorption and noise reduction, cotton materials are superior to inorganic hard materials; resistance to sagging, calcium silicate is stronger than gypsum, etc.

For long boards, such as 600*1200mm, 600*1500mm, 600*1800mm specifications, the cost ranking is: cotton materials > gypsum > calcium silicate. The longer the length, the more obvious the price advantage of calcium silicate.

For concealed frames, as mentioned earlier, only cotton materials need to be considered.

Since choosing a ceiling is not complicated, why does our title say that it is important to detach from concepts?

Due to the special nature of non-metal materials, the decorative surface of most non-metal ceilings relies on sprayed coatings. Concepts such as antibacterial and negative ions contained in the coatings are naturally added to the ceilings. Of course, among non-metal materials, in addition to cotton materials, other materials such as calcium silicate and gypsum can also add small amounts of silver ions and vermiculite to increase product selling points. These added product selling points are optional compared to the material itself. Having them is better, but not having them doesn't affect anything. If we choose materials based on these added selling points, it's a bit of a case of putting the cart before the horse. The story of "buying the casket and returning the jewel" is repeatedly staged, not because of stupidity, but because of bad intentions.
