Light mineral wool board is easy to transport and install, beautiful sound absorption, light and safe, and conducive to fire prevention.

The actual size of mineral wool board refers to the size of mineral wool board that we can actually measure. The actual size is usually less than the nominal size of the mineral wool board. Because the width of keel and installation error must be considered when installing the mineral wool board, the convenient installation space must be reserved in the production and cutting process of mineral wool board. According to the thickness of support keel used by different manufacturers, 5-7mm is usually reserved. The actual size of the mineral wool board is more clearly reflected in the grading mineral wool. At this time, the size of the gradual change edge of the mineral wool board will be clearly reserved for the actual installation.

The thickness of light mineral wool board will affect the ceiling of mineral wool board

1. The thickness of light mineral wool board will affect the mineral wool ceiling through special corner size treatment. When choosing the specifications of mineral wool board, the specifications of gradient mineral wool board and flat board are different. The ink drop size of mineral wool board used in some special places requires the thickness of mineral wool board. When the mineral wool board falls, it should be chamfered according to the thickness of the mineral wool board. If the thickness of the mineral wool board is too small, it is easy to cause serious damage to the falling edge of the mineral wool board. The ceiling loss of mineral wool board is too large, and the mineral wool ceiling is easy to sink, crack and sag.

2. The thickness of light mineral wool board affects the moisture resistance of mineral wool board. The moisture resistance RH index of mineral wool board is directly related to the thickness of mineral wool board. The thicker the mineral wool board, the better the moisture resistance and the higher the RH index. In the area with high air humidity, it is recommended to use mineral wool board with higher thickness, such as 16mm, 18mm, etc., and it is not recommended to use special boards with 12mm and 14mm. Although the thicker the sheet, the more expensive it is, for safety reasons, in order to prevent the mineral wool board with good ceiling from sinking due to moisture, please choose the mineral wool board with strong moisture resistance.

3. The thickness of light mineral wool board will affect its fire resistance. The fire protection index of mineral wool board is the most stringent requirement in buildings, and it is also the general requirement for the use of class a fire-proof building materials in the ceiling of buildings. The thicker the mineral wool board is, the higher the fire index is. For the safety of buildings, please choose the thickness of light mineral wool board with high fire resistance.
