A lot of materials appeared in the press about the harm to the health of the now widely used mineral wool. In principle, perfectly harmless materials simply do not exist. However, now we will not talk about sanitary norms and maximum permissible concentrations of the premises contained in the mineral in the air, since we are interested in insulation of the house with mineral wool on the outside. In this case, you can not talk about the harmful properties of the material at all. The release of harmful substances from the material is so small that when using the material outside the premises, it makes no sense to talk about it at all.
As an isolation material of the mineral wool, most of the indicators significantly exceeds other materials used today for this. First of all, it is necessary to mention almost complete fire safety. Actually, there is nothing surprising in this if you recall what serves as a raw material for the manufacture of this material. Mineral wool of glass melt (glass wool), rocks (stone wool) or slag (slag wool) is made. Accordingly, insulation of the house with mineral wool provides the highest stability of thermal insulation to the fire. The structure of the mineral wool also provides its excellent soundproof properties. Thanks to the use of this material, the sound permeability of the walls decreases repeatedly. The relatively small share of the material is also of great importance, due to which the load on the supporting structures increases slightly.
Finally, it’s time to talk about the heat -insulating properties of mineral wool. Mineral wool use technology can be different. As a heater it can be used for plastering facades. In addition, mineral wool is used as a heat -insulating filler in ventilated facades. Using glass wools, sandwich panels quite popular today. It is widely used to isolate the inter -story floors and roof insulation. It should be noted that the insulation of the house with mineral wool is very effective, because its thermal conductivity is almost half as much as that of the rather popular foam today.
