Suitable whether basalt rock wool to create a warm and quiet in the house ?

Basalt mineral wool: Production

mineral wool based on basalt produced by mixing and melting metallurgical slags and rocks (basalt).The result is a fibrous material with the best performance and long life.This is achieved by the fact that in the manufacturing process rocks applied without adding any mineral and synthetic substances.

Only in some cases include a composition or blend of 10-35% limestone to the material was more resistant to corrosive components, and high temperatures.But to say that the mixture thus manufactured is a basalt fiber, it is impossible.Rather, it's just a rock wool.

Continuing to speak of mineral wool on the basis of basalt, remember that it can be performed at a pre-set parameters of length and thickness.There are the following kinds of it: BTV and BSTV .The first is thin basalt fibers with a thickness of 5-15 microns.Second - superthin basalt fiber with a thickness of 1-3 microns.Length - 50 mm (in both species).Plus, a very popular mineral basalt slab.

Basalt mineral wool: properties

As already mentioned, thanks to special components within the composition of the material, provided the relevant performance characteristics.Positive properties are:

  • Provides long life , an average of about 30-40 years.
  • not create favorable conditions for the development of mold, fungi and other microorganisms .
  • has low thermal conductivity . created it through the fiber structure of mineral wool.
  • Fireproof and non-combustible material.In addition, flame-retardant and does not emit toxic substances.
  • provides excellent sound insulation.
  • Resistant to vibration and is not destroyed by it (unlike other insulation).
  • eco-friendly material does not contain any carcinogens.Further, its chemical formula is the same as that of the basalt.
  • withstands extreme temperatures and can be used at t up to 700 ° C (long-term) and up to 1100 ° C (short-term).

Negative properties include the high cost.Also, due to the existing gaps between the tiles material can pass the heat to the outside.

But these minor shortcomings do not prevent consumers to use mineral wool in different areas of construction.It is used in civil, industrial, residential insulation.In particular, you can often find the material for power equipment, marine structures.Plus, of course, it is used for the insulation of houses, saunas, steam baths and other facilities.

few words about laying flooring

Basalt mineral wool on the walls, the roof, attic, facades, flooring, interior walls of the room.When installing the floor insulation is laid directly on the concrete slab under a cement screed.Moreover, its density must be 160kg / m3.

If it is assumed in the installation logs, you must first lay the insulation with a density of about 50 kg / m3.Only then he laid the floor.In both these methods, Basalt mineral wool is placed without any particular attachment (ie no need to use dowels or glue).

If you plan to wall insulation (usually it is "wet" method), then to start preparing the ground.Eliminate the old coating.To do this, you need to know how to remove the old plaster, paint.

Then clean any protruding parts and primed base.And then proceed to laying of the insulating material to have a density of about 80 kg / m3.Attach it with glue and dowels.Then reinforcement is applied and decorative plaster.
