Features stone (basalt) cotton

Basalt (stone) wool - moderninsulation material in the production of natural ingredients which are used. In this sense, it is close to such materials as glass, slag and combines them into one group - mineral insulation materials.

Home of the main characteristics of stone wool -its ability to retain heat, and this indicator is very close to the standard: fixed air gap. This is achieved by the fact that the material has a highly developed fibrous structure in which a lot of air and held stationary. Fiber material is very thin, their amount per unit volume greater than the other materials, respectively, and they can hold large quantities of air.

Insulation stone wool is obtained from the veryhard rock, such as basalt and gabbro. In the production of rock is melted and the melt is then passed through filters to fiber formation.

This applies when installing insulation of walls, floors, walls, roofs of different types, tubes and pipes, as well as in industry for protection against the cold production units.


  • Fire. Basalt (stone) wool is not combustible and its fibers begin to melt only at temperatures of more than a thousand degrees.
  • Heat. Due to the low thermal conductivity values ​​of the room, warmed by this material, well retain heat during the cold season, and protect from excessive heat in summer.
  • Moisture. Stone does not get wet in water, respectively, and fibers produced from rocks, not absorb moisture. Such material is not afraid of rain and leaking.
  • Time. One of the unique characteristics of stone wool - its ability to not lose their insulating properties for a very long time. The period during which it maintains performance - more than a century!
  • Ecology. This material does not contain substances that can harm health - hence can not allocate them to the surrounding atmosphere.
  • Sound. Insulation rock wool because of its structure and has good sound-insulating material. Planted under the roof, it will mute the sound of the rain and under the floor in the nursery - will ensure a relaxing stay around.
  • The form. The properties of the material and its structure is such that mechanical loads on it practically does not react. This allows the use of basalt (rock) cotton in areas where it may be exposed to pressure, torsion, or other influences.
  • Saving. The advantages also include a fairly simple technology at work laying the insulation, which reduces installation costs. Also it is necessary to take into account an increased efficiency in heat saving, because the insulation rockwool twenty times superior to this indicator, the brickwork. Savings on heating at the same time can be up to 60%.


  • Negative characteristics include rock wool primarily rather high price of insulation made from it.
  • Furthermore, to ensure a tight connection to docking locations of sheets is difficult.
  • Another negative point: with a heater to work in a respirator, because it can be split into very small particles, which are harmful to health.
