One、Why do mineral wool insulation boards turn yellow?
1、The quality of mineral wool insulation boards is poor.
When the material of mineral wool insulation boards is defective, or when the quality of the coating materials used for treatment is poor, the mineral wool insulation boards will oxidize and change color after being exposed to air after installation.
2、Mineral wool insulation boards have been used for too long.
Using mineral wool boards for extended periods can also cause them to yellow, but this is a normal wear and tear phenomenon. If it does not affect the insulation performance, maintenance is not necessary.
Two. What to do if mineral wool acoustic panels turn yellow?
1、Contact after-sales service
If the yellowing is caused by quality issues with the mineral wool acoustic board, the manufacturer should typically handle the warranty claim. However, this must be done within the warranty period, and you should bring your warranty card to the manufacturer.
2、Replace again
If the warranty period has expired or the mineral wool insulation board has yellowed naturally due to prolonged use, it will need to be removed and replaced manually. We recommend using products from reputable brands, and choosing darker colors to minimize yellowing.
