What's the difference between basalt rockwool and slag mineral wool?


Insulation stone wool – one of the most environmentally friendly materials. Like any other material to keep warm, it uses air as the most effective thermal insulator. "Fix" air bearing and force it to isolate the room from the cold, his "can" of fiber material in their wool-like condition.

The fibers may be organic, that is, vegetable origin, such as cotton at the pharmacy, or inorganic, ie mineral. Since only suitable manufacturing non-combustible insulation materials used for this purpose are based on mineral fibers.

Minerals from which you can have thin and long fibers, not so much. This is primarily – glass, different slags, and some stones, such as basalt, after appropriate processing.

Consider the most popular insulation material produced on the basis of minerals. The conductors for the three are: glass wool, slaggull and basalt wool.


This insulation is characterized by low thermal conductivity, good vibration loads, and a well-compressed, reducing the amount of six times, reducing transport costs.

The most well-known manufacturers on the market for this type of insulation: "Isover", "KnaufInsulation", "Ursa".


heat conductivity index from the resulting material is lower than glass wool insulation, better and other indicators, such as vibration resistance. It is less absorbing moisture and does not burn. Basalt wool may be possible to have a lower density, and then it will be flexible or raised – and then it will show durable material.

Given that basalt fibers can produce materials with different strength properties, to give them a different shape, and apply a variety of coatings, insulation from it is more versatile than other types of mineral wool.

Elastic, soft stone wool products are used where there is no high mechanical load, low buildings (up to four floors) with insulating wells. Tighter species can be used in the construction of high altitude buildings. It provides sound and thermal insulation, is safe when it comes to fire demands. Figured products from this wool are isolated from the outer tubes temperature and piping.

When the heater will drive the mechanical stresses, rigid insulation is applied basalt wool modification.

One of the most important criteria for the applicability of this or other isolation is its resistance to mechanical strain. Previously reinforced cargo holds only high density materials, but today there were materials and withstand considerable effort at low densities. In any case, it is necessary to take into account the amount of strain it will have in selecting materials.

Stone wool is made on a substrate foil or web of glass filament, for increased strength it can sew with wire or fiberglass wires.

So, if you want to attach the insulation between the discs hardly any suitable insulation wool or slaggull, because they are very fragile crashes. In this case you should choose wool from basalt fibers. When roof insulation is much more important than another indicator of how well it can withstand the pressure and compression.

Another of the best available species minerals – slagg. It is made of blast furnace slag (glass body or rocky mass, which is a deviation in steelworks, melting of crude iron in blast furnaces).

Indicator thermal conductivity of the material It is quite high, but it has some significant disadvantages. Slag absorbs light and fast water, which implies restrictions for its use in wet rooms, for example for thermal insulation of facades and bathrooms. Thus, chemical processes begin which lead to an increase of acid content, and thus destruction of the surrounding metal wool elements. Another disadvantage – low vibration resistance. Currently almost never used.
