Each owner of his own apartment or house, who wants to live in comfort and peace, tries to protect himself from extraneous noise and winter cold as much as possible. For heating, at first the fire of fireplaces and boilers was used, after which they were joined by electric heaters. All this is not so effective if the house is not well insulated and has places through which precious heat escapes. However, if you use mineral wool insulation, you can protect your home from frost in the winter and also from the heat in the summer.
Mineral wool insulation has several varieties, each of which has its own advantages and disadvantages. In order to make the right choice in the direction of one or another insulation, it is necessary to become more familiar with the quality characteristics of the materials.
Main types of mineral wool
After reviewing the information provided in GOST 52953-2008, you will learn that three materials belong to mineral wool, namely: stone wool, fiberglass and slag wool. Any of them can be purchased by visiting the building materials store. Each of these varieties hasa certain thickness and length of the fiber, and also differs in quality characteristics. For example, they have different resistance to stress, moisture resistance, and thermal conductivity.
Glass wool has been used for a very long time, and today it can be purchased at the lowest possible price. But working with it, unlike slag wool and stone wool, is very difficult, since it is prickly. The master during the installation process will have to use personal protective measures.
Glass wool characteristics
If you need mineral wool insulation, then you can pay attention to glass wool, which consists of fibers with a thickness ranging from 5 to 15 microns, while their length can vary from 15 to 50 millimeters. Glass wool is strong and resilient, and its thermal conductivity varies from 0.03 to 0.052 watts per meter per Kelvin. It is possible to heat the material without damaging the structure up to 500 degrees, and the optimum temperature, when the thermal insulation will retain its characteristics, is 450 degrees. As for the minimum temperature, it reaches -60 degrees.
Slag characteristics
Mineral wool insulation is also on sale and slag, which is made from blast-furnace slag. The thickness of the fibers of the material is equal to the limit from 4 to 12 microns, but their length is equivalent to 16 millimeters. Due to the fact that slags have residual acidity, in a damp room they are able to act on metal objects. Slag wool absorbs moisture well, so itshould not be used for thermal insulation of external walls of buildings.
For the above reasons, this material cannot be used to insulate water pipes that are made of plastic or metal. The thermal conductivity coefficient is greater compared to the variety described above and ranges from 0.46 to 0.48. The insulation can be heated up to 300 degrees, while it will not lose its quality characteristics. If this value is exceeded, then the fibers will begin to sinter, and the material will lose its thermal insulation characteristics. The hygroscopicity of this insulation is very high.
Stone wool characteristics
Mineral wool insulation is also presented in stores in the form of stone wool, the fibers of which are approximately the same in size as those of the above-described slag wool. However, the advantage is that the elements do not prick, so it is safer to work with stone wool. The thermal conductivity coefficient can be equal to 0.077, while the maximum value is 0.12. The material can be heated up to 600 degrees without losing its properties.
Characteristics of bas alt mineral wool thermal insulation on the example of "TechnoNIKOL Technofas Effect"
Bas alt mineral wool insulation of this brand is intended for use not only in industrial, but also in civil construction. Such plates are used as sound and heat insulation in external insulation systems.walls. After the installation of the material, a protective and decorative layer of thin-layer plaster is laid. Thermal insulation does not burn, it is represented by hydrophobized slabs, which are made on the basis of rocks of the bas alt group. A low phenolic binder is used in the manufacturing process.
Quite often, specialists are interested in the density of mineral wool insulation. In the described case, this parameter changes from 131 to 135 kilograms per cubic meter.
It is possible that for installation work you will have to equip the crate, for this you need to ask about the dimensions of the plates. For example, the length can be equal to 1000 and 1200 millimeters, as for the width, it is equivalent to 500 or 600 millimeters. Thickness in increments of 10 mm varies from 40 to 150 mm. The vapor permeability of this insulation is 0.3 Mg / (m h Pa), while the humidity by weight does not exceed 0.5%. Water absorption is not more than 1% by volume, and the organic content can be 4.5% maximum.
Characteristics of rockwool insulation brand "Rockwool Light Butts"
Rockwool mineral wool insulation is very popular among consumers today. A variety of thermal insulation "Light Butts" is a hydrophobized thermal insulation boards, in the manufacturing process of which stone wool based on bas alt rocks is used. The main feature of this insulation is a unique technology that provides for the formation of oneedges of the plate so that it has the ability to expand and contract. Due to the ability to spring, installation is facilitated when mounting structures on a metal or wooden frame.
The described mineral wool boards have many advantages. Among them, it is worth highlighting the absence of cold bridges, durability, environmental friendliness, fire safety and the most dense adjoining to each other.
Use of Rockwool "Light Butts" insulation
These slabs are used as a non-load-bearing layer in the construction of attic spaces, light coverings, interfloor ceilings, as well as partitions and walls of low-rise buildings. This can include sloping and vertical walls in attics, as well as a layer in hinged facade systems. In the latter case, there is a need to form an air gap when a two-layer insulation is installed. These mineral wool boards should not be subjected to significant loads. During the installation process, the master will be able to form a surface without the formation of cracks. As a result, drafts will not form inside the premises, and a comfortable temperature will be maintained in the rooms.
Thickness Rockwool "Light Butts"
In order to provide the house with thermal insulation qualities as efficiently as possible, you need to ask what is the thickness of the mineral wool insulation. In the Light Butts variety, this parameter varies from 50 to 100 millimeters. While the length and width remain the same and are equal1000 and 600 mm respectively.
