Fibertex 650 has an NRC of 1, which is the highest possible rating for soaking up sound. It is also known as stone wool insulation or Rockwool and is composed of mineral fibre.
Want to make your own sound absorbers? This industrial acoustic insulation is ideal for you. Additionally, you can wrap it in fabric and customise its look. This is a heavy-duty product and can handle continuous operation up to 650°C. Moreover, it is non-combustible. Panels can be installed in large generator bays, around pool equipment and many enclosures where reverberation noise needs to be controlled. However, the best part about Fibertex is how cost-effective it is!
