Although they are both excellent insulators there are a few differences which explains why mineral wool is becoming more prominent nowadays. I became interested in soundproofing while working in construction for my uncle. Rockwool also doesn't absorb water as fiberglass does. Thankfully, both Rockwool and fiberglass insulation have good resistance to water damage, which can even be improved further if you buy faced insulation, which includes a layer of foil or a paper-like material on the outer layer to serve as a sort of vapor barrier. Note: Here I will be going over which type of insulation material works best when put inside a typical interior wall with of drywall on either side, which has an STC rating of 34 on its own, and how it increases this rating. Rock wool and fiberglass are made from natural materials, and both have insulating properties. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal and acoustical insulation properties.

The short answer is open-cell foams perform about the same, acoustically, as fiberglass and mineral wool. Because of its nature, it does not ignite and keeps the fire from spreading. Rockwool is made of mineral wool and is better at absorbing low frequency sound ranges while fiberglass contains small particles of glass and suited for most soundproofing jobs. The flame spread index is determined by the distance that a flame travels along a test substrate in a specific timeframe to determine its propensity to burn and how rapidly it can spread flames. plant growth widely used as soil for plants, it comes in different forms and sizes.
