Stone wool

basalt (rock) wool - insulation is manufactured from basalt belonging to the hardest materials, its structure individual species mineral basalt group may include.Size superfine fibers - 3.1 microns, the size of fine fibers ranging from 5 to 15 microns.The average fiber length - 50 mm.These fibers are arranged randomly, endowed matter excellent insulating properties.The photo and video can be clearly seen, it looks like the structure of the material.

Scope

Scope of basalt wool is very wide.You have to understand that this kind of mineral wool.It is the involvement of a group of mineral insulation makes it possible to use this material in the following cases:

• insulation of ceilings, walls, floors, this wool is laid inside the walls, under the screed, plaster, sheathe the top;
• insulation of pipelines;
• improvement of sound insulation;
• formation of fire protection, because this material only melts at very high temperatures.

Types

There are several varieties of basalt rock wool, each of them has its own field of application.

1. Soft.It can be used when heavy loads are not scheduled.For example, for the arrangement of ventilated facades with insulation or frame houses.This version consists of very fine fibers, which are excellent at keeping you warm.
2. medium hardness.Apply in ventilated facades and insulation of the ventilation units and ducts.
3. tough.It can be used where there are assumed to strong mechanical loads.For example, where the insulation is done under the subsequent reinforcement and plaster.This also applies to walls and floors, if on top of wool made screed.
4. Special insulation for pipes in the form of a cylinder.
5. Foil material.It is used for increased thermal protection.After all, this wool is not only retains heat, but also reflects its interior space.

this insulation varies in thickness.Maximum thickness - 100 mm.Of course, the thickness influences the thermal insulation characteristics.The thicker layer is in the warmer environment.However, in the opinion, to work with thicker varieties uncomfortable, so better to stacking in multiple layers.For the convenience of basalt wool comes in several forms:

• in rolls;
• in slabs;
• in the formless state (for pneumatic).

material properties

Among the main properties of stone wool are the following:

• excellent sound insulation and thermal insulation parameters;
• fire safety;
• high strength;
• water vapor transmission rate (as opposed to foam, which does not allow the walls to "breathe");
• durability;
• not rot.

Specifications basalt wool

strength of the material due to good ability to resist stress.This quality is due to the high density of wool - 30 - 100 kg / m³.Such densities provide rigidity, allowing the material to operate for about 50 years.The fibers do not retain moisture, so the material is always dry, and becauseit does not accumulate moisture, accordingly its weight is not increased when contacted with water and does not cause damage.Hygroscopic material low - less than 1%.The thermal conductivity of the material - 0,042-0,048 W / m * K.

material has a porous structure, which gives the ability to absorb air, noise impact.This characteristic makes the basalt wool excellent means providing sound insulation.It is advisable to use the material to protect the structures from potential destruction by fire.He did not light up, it begins to melt at a temperature above 1000 ° C.
