Humidity resistant ceilings avoid “ceiling sag”

Our stone wool ceiling products stand up to humidity.

Stone wool is a hydrophobic material, meaning it does not absorb water and does it not hold moisture. This makes stone wool ceiling panels not only humidity-resistant but also sag-resistant. They remain dimensionally stable even up to 100 percent relative humidity (RH) and in temperatures ranging from 32 to 104 degrees Fahrenheit (0 to 40 degrees Celsius).

Ceiling sag

With some acoustical ceiling tiles, humidity can weaken the structure of their materials and cause them to sag, drooping beneath their ceiling suspension system. In extreme cases, sagging ceiling tiles may even fall out of their grid. This often will happen in buildings under construction, where the building is not yet temperature-controlled and humidity-controlled, or materials have not yet dried.

Our stone wool ceiling panels do not warp, curl or cup. They do not rot nor corrode. With virtually no organic content, they are naturally resistant toward mold, mildew and microorganisms. There is no risk of sagging – even inconsistently ”wet” rooms like kitchens, restrooms and pool areas.

Stone wool ceiling panels can be installed in the early stages of construction, when the windows are not fully sealed, without any risk of sagging. Our moisture resistant acoustical ceiling tiles characteristics remain unaltered over time, maintaining their shape and physical characteristics throughout a building’s lifecycle.

We tested ceilings for moisture resistance and compared Rockfon with products from other manufacturers. We placed different samples into containers of water and compared the results. The other ceilings disintegrated, while the Rockfon ceilings were totally unaffected.
