First of all, it should be clear that handmade rock wool sandwich panel itself does not have complete waterproof performance. Its surface is usually covered with metal or coating, but this covering layer cannot completely prevent moisture penetration. Especially under long-term use or severe climatic conditions, the surface coating may age, crack or fall off, resulting in moisture penetration.
However, in terms of moisture resistance, handmade rock wool sandwich panel shows certain advantages. The rock wool material itself has certain hygroscopicity and air permeability, which can regulate indoor humidity to a certain extent and reduce the occurrence of moisture. At the same time, during the installation process, a layer of moisture-proof material can be coated on the surface of the rock wool sandwich panel to further enhance its moisture-proof performance.
In order to improve the waterproof performance of handmade rock wool sandwich panel, a series of measures can be taken. For example, special seals are used to seal the joints of the rock wool sandwich panel to prevent moisture from penetrating from the joints. In addition, a waterproof layer, such as waterproof roll or cement layer, can be added to the outer layer of the rock wool sandwich panel to form a more effective waterproof barrier.
It is worth noting that although measures can be taken to improve the moisture and water resistance of handmade rock wool sandwich panels, these measures can only work to a certain extent. In extreme weather conditions, such as heavy rain or long-term immersion, moisture penetration may still occur.
Therefore, when using handmade rock wool sandwich panels, it is necessary to evaluate their moisture and water resistance according to specific application scenarios and needs. If the building requires more stringent waterproofing requirements, it is recommended to use professional waterproof materials or take other waterproofing measures to ensure the safety and stability of the building.
Handmade rock wool sandwich panels show certain advantages in moisture resistance, but additional measures need to be taken to improve their performance in waterproofing.
