Moisture-proof performance is a very important indicator to test the quality of mineral fiber ceiling tiles. Moisture-proof refers to the degree of resistance to subsidence of mineral fiber ceiling tiles under a certain temperature environment. For example, in cities with a lot of rain, moisture-proof mineral fiber ceiling tiles must be used for ceilings. There is a lot of rain and high humidity. Ordinary mineral fiber ceiling tiles are easier to sink in this environment, and the visual effect is not very good. Under the condition of correct installation, moisture-proof mineral fiber ceiling tiles is generally not easy to sink. This is also the reason why moisture-proof mineral fiber ceiling tiles are more expensive than ordinary mineral fiber ceiling tiles.

The back of the moisture-proof mineral fiber ceiling board is mainly green and yellow. Customers can specify the color of the back. In order to distinguish it from the products on the market, the color is suggested to be green. The thickness of the moisture-proof board is recommended to be at least 14mm, because the thicker the board, the better the moisture-proof effect. Ordinary quality boards thickness can be as low as 12mm. We can make 12-20mm for thickness.

The raw material of the mineral fiber ceiling board is slag wool, which is an inorganic fiber and has good heat preservation, heat insulation and sound absorption functions. They have the characteristics of low density, low thermal conductivity, non-combustibility, and good sound absorption effect. Moreover, it has a certain degree of elasticity and softness, and is suitable for filling materials in various shapes of thermal insulation and sound absorption projects.
