Mineral cotton wool photo High sound insulation and heat insulation characteristics, as well as moisture resistance and fire resistance make mineral wool products when building objects of the most varied value irreplaceable.

Thermal conductivity of mineral wool

Mineral wool is a heat-insulating fibrous material that is obtained as a result of melting metallurgical slag, mountain silicate rocks and their mixtures. From such a material, thermal insulation panels are manufactured for building objects, which can be used in external and internal insulation systems. If necessary, some types of insulation are installed under tension, gypsum or suspended ceilings. Its properties make this material indispensable and widely used.

Because of the raw materials used for production, mineral wool is divided into slag and stone. In the latter case, such rocks as diabase, dolomite, basalt and limestone are used, and in the first - slags( industrial waste of metals).Raw material undergoes excessive heating with further formation of mineral fiber by centrifugal or blowing method. The flow of the melt is effected by centrifugal force, compressed gas or water vapor, resulting in the production of the finest fibers that are subsequently compressed. The resulting mineral wool has an increased sound insulation and thermal insulation ability, moisture resistant and non-flammable.

Thermal insulation characteristics and properties, are based on reduced thermal conductivity. The orientation of the compressed fibers is not the least important: the scattered arrangement guarantees better thermal insulation, however, the vertical position helps to create a lower density plate if the strength is maintained. Non-combustibility allows its use in the form of fire insulation, as products made of such material, sufficiently effectively prevent the spread of the flame and do not emit harmful and toxic substances under its influence.

Mineral wool - good sound insulation

Mineral wool good sound insulation photo The soundproofing characteristics of mineral wool are also achieved due to the peculiarities of the structure of the insulating product. Between the chaotically arranged fibers, sound waves are not created. Water-repellent characteristics, the material receives by impregnation with special compositions, which, if necessary, allows the insulation of the objects even in rainy and wet weather.

Heat-insulating mineral wool products are used in heat-insulating multilayer systems, among which is the external insulation of the "wet" type, the insulation of the internal walls of the structure( sandwich panels, three-layer reinforced concrete or concrete panels, laminated masonry), the heat-insulating layer in ventilated hinged facades.

In those facilities where the insulation is subjected to stress during the operation or during installation, rigid mineral wool heaters are used, which are also used for thermal insulation of socle buildings and floor systems, not only insulating it, but also significantly increasing the soundproofing properties of the interfloor floors.

Such boards are designed for use for insulation of surfaces without a screed device made of reinforced concrete or metal profiled flooring. For the most effective thermal insulation, contact mineral wool with the surrounding air.

Mineral mats are used for thermal insulation of heat carriers in road communication systems, as well as for insulation of equipment and pipelines of industrial enterprises. In addition, mineral wool mats are used to insulate rooms that are subject to increased environmental requirements.

Mineral wool is a filler of sandwich panels. It is laid between the walls of panels so that the position of the fibers is vertical, which in turn gives additional rigidity to the panels and provides them with higher thermal insulation qualities.

High water resistance and fire resistance, low thermal conductivity, as well as the durability of mineral wool make it an indispensable product for sound and heat insulation of pipelines, industrial premises, residential buildings, and other objects, for these properties it is so popular. At the present time, mineral wool mats, plates and other products firmly occupy the first places among effective and environmentally friendly thermal insulation materials.

There are general rules that experts recommend when working with such material.

Mineral wool - useful tips for using

Useful tips for using mineral wool photo Accurately following the instructions on the packaging will avoid unpleasant mistakes and alterations. Cutting of such material is carried out with the help of a special knife.

Working with such material, it is necessary to pay attention to the fact that its edges are not torn and worn.

From time to time, the material must be laid in several layers to obtain the desired thickness of the thermal insulation layer.

Mineral wool should adhere well to the surrounding structures. For a quality effect, the space to be insulated must be full.

Application of this material is gaining momentum, due to its useful properties and characteristics, is being introduced into many stages of apartment repair by one's own hands.
