PUF VS. Rockwool Panels, Which Should You Pick?

Before you can pick between the two, it is best to understand their differences first. The PUF panels are made by combining polyol and isocyanate in the ratio 2:1, respectively. As for rockwool panels, they are made by spinning molten rocks, slags, and ceramics into fine fibers.

PUF is seen as a better heat insulator with a lower K value. So, it would provide better insulating properties. On the other hand, Rockwool has a higher K value than PUF panels meaning its ability to contain heat is less.

PUF is more flammable than rockwool. It is why the material would not be recommended for use where fire hazards seem like a big concern. Rockwool panels can withstand high temperatures of even 1000 degrees Celsius without melting. This makes the panel highly resistant to fire.

PUF panels have a lower density. This means they will be lighter generally and easier to handle. Also, the installation is faster than when using rockwool, which is heavier. The rockwool panels would also need more people to complete the job.

The clean room PUF panels are not the best when soundproofing is vital. You should rather opt for rockwool as it will break the acoustic waves and thus have better sound-absorbing properties.

If you are on a budget, the PUF panels will be a great choice. Rockwool will cost an average of 15% more than the PUF panels. So, the rockwool panels are considered premium panels.

Since the clean room PUF panels are cheaper and better heat insulators, they are a great choice for hotels, hospitals, cold storage, commercial buildings, and pharmaceuticals. Rockwool is best for applications that need better soundproofing and fire resistance. So, its applications include studios, offshore platforms, and marine applications.


Clean room PUF panels are some of the most versatile clean room panels you can buy today. They are designed to deliver on the best performance in terms of insulation, fire resistance, and more. As such, you should be able to handle your clean room applications better.
