ROCK WOOL BOARD
1. Choosing a lower thermal conductivity is an important index to measure the performance of rock wool board. The smaller the thermal conductivity is, the less energy transferred through the material, and the better the thermal insulation performance of the insulation rock wool panel is.
2. Sound absorption coefficient should be high. The sound absorption effect of insulation rock wool board mainly depends on the density of rock wool panel in unit area. The higher the density is, the better the sound absorption effect.
3. Good rock wool panel should have low moisture absorption. After most insulation materials absorb water, their thermal insulation effect will be significantly reduced, because water has a higher thermal conductivity. Therefore, when choosing rock wool panel, it is better to choose waterproof.
4. High quality rock wool panel must have high strength to support self-weight.
