The function of rock wool is to prevent fire and block the gaps in its apertures to walls, floors, and ceiling. Rock wool’s resistance to fire feature has been under a more-than-four-hour test and is measured. Their property of covering the gaps in plaster or concrete structures, walls, and also in the application of floor where pipeline, cables, and canals crosses them, is measured and approved.

One of the most outstanding features about rock wool is their unique fire endurance. Rock wool is neither flammable nor it easily ignites. So it is kind of known as a fire protection. Metal structures in the time of fire because of the high level of heat lose their mechanical strength. Their melting and transfiguration results in the break-down of the whole structure. In order to prevent the issue of Metal structures it is common to, especially forStructures, insulate them by an appropriate means and using rock wool. Consequently, even if a fire persists for even ten hours there will be no problem for the structure what so ever. For this reason, in some countries insurance companies tend to give special discount for the structures which is insulated. Furthermore, all of the buildings in Oil platforms which are designated for the residence of staff are structure-insulated, in case a fire breaks out they will be safe until the arrival of help.

Durability

Contrary to some of the Polymer Foams which have not enough durability and lose their figures and qualities over time, rock wool insulation won’t age and become defective. Furthermore, they preserve their features as effective insulations and they even will survive as long as the building lifetime.
Another important feature of rock wool is that not only they are very good insulations, but they also can be used as soundproof or fire insulation. The fiber structure of rock wool provides acoustic and sound absorption features for these insulations. However, their wonderful resistance feature toward high temperatures and also the feature of resisting fire have resulted in them being among fire insulations. Accordingly, rock wool as thermal insulation, sound proof, and fire insulation can be considered as the best choice of insulation for constructions such as residential, hospitals, schools, libraries, mosques, stadiums, restaurants and etc.
