How to identify the quality of rock wool board?
The quality of rock wool board directly affects its thermal insulation, sound absorption and noise reduction, fire retardant and other properties, so it needs to be carefully identified when purchasing. Here are some ways to identify the quality of rock wool board:
- Observe the appearance:
Color: High-quality rock wool board has uniform color, yellow-brown or grayish white.
Surface: The surface is flat, without obvious defects such as bumps, cracks, impurities, etc.
Fiber: The fiber is fine and uniform, without lumps, breaks, etc.
- Measure density:
Density: The density of rock wool board directly affects its performance. Generally speaking, the higher the density, the better the performance.
Method: You can use an electronic scale to measure the weight of the rock wool board and then calculate its density.
- Check the test report:
Test report: Rock wool boards produced by regular manufacturers will provide product test reports.
Content: The test report should include indicators such as thermal conductivity, sound absorption coefficient, and fire rating.
- Other methods:
Burning test: Use a lighter to light the rock wool board. High-quality rock wool board is not easy to burn, and there is no black smoke and odor after burning.
Feel: High-quality rock wool board feels soft and elastic.
Price: The price of high-quality rock wool board is relatively high, but the cost performance is also higher.
In short, to identify the quality of rock wool board, it is necessary to consider factors such as appearance, density, and test report. Only by choosing products produced by regular manufacturers can its performance and safety of use be ensured.
The following are some common questions about the quality of rock wool board:
Is the higher the density of rock wool board, the better?
The higher the density, the better the thermal insulation, sound absorption and noise reduction, fire retardant and other properties of rock wool board, but the price is also higher.
How to judge the fire resistance level of rock wool board?
You can find out the fire resistance level of rock wool board by checking the test report or consulting the manufacturer.
How long is the service life of rock wool board?
The service life of high-quality rock wool board can reach more than 50 years.
