Rockwool mineral wool: technical specifications, purpose, testimonials. Rockwool Heater
If you seek to live in peace and comfort, then,must, like many others, try to protect your house from extraneous noise. The attendant issues here will be the insulation of the building and its protection from the summer heat. Quite often, mineral wool based materials have recently been used as insulation. They allow to solve the above-described tasks. In general, to the category of "mineral wool", according to state standards are products that are classified into several varieties, among them: glass wool, stone wool and slag wool.
Mineral wool may have a different density,which affects the level of thermal conductivity. This characteristic of this insulation is negligible. However, in the process of operation, the thermal conductivity increases, because the structure penetrates moisture. In order to make the thermal insulation system more efficient, the layer must be protected. Among others, Rockwool mineral wool is on the market. It will be discussed below.
Description of the material
Mineral wool from the manufacturer Rockwoolis made on the basis of natural basalt, it allows using the material for soundproofing and warming of any structures and structures. This includes hospitals and children's institutions. Raw materials in the production process are exposed to high temperatures, resulting in the formation of fibers that are formed by pulling in the thread. For form stability and hydrophobicity, a certain amount of binder is added to the thermal insulation, this makes it possible to obtain fibrous plates that are distinguished by outstanding operational characteristics.
Rockwool mineral wool found its wideSpread. The manufacturer offers for sale material that allows you to solve a variety of tasks for repair and construction. Thermal insulation helps in creating an acoustic and thermal barrier in the area of:
With the help of mineral wool, you can heat steam,saunas and baths. The material has found its application in the isolation of commercial, residential and industrial premises. With its help it is possible to heat insulate equipment, fireplaces, stoves, tanks and piping systems. Rockwool mineral wool can be an effective fire retardant for structures and cable penetrations.
The products described are rather competitive, according to consumers, it has many positive features, among which:
- fire safety;
- acoustic comfort;
- ecological compatibility;
- ability to preserve heat.
Mineral cotton wool under the influence of fire willprevent its spread. This sometimes allows you to create suitable conditions for saving people. Fibers can undergo heating up to 1000 ° C. In case of fire, structures covered with mineral wool can become protective.
At extreme heating, the layer of cotton wool does not smoke, butalso does not become a source of molten droplets. Rockwool mineral wool, according to buyers, provides acoustic comfort. Plates are capable of absorbing structural, vibrational and other noises. The protective layer copes with these tasks more effectively in comparison with similar materials. This property was achieved thanks to the chaotic interweaving of fibers, between which air cavities are formed, communicating with each other.
Why choose Rockwool?
Mineral wool was awarded a marksecurity EcoMaterialGreen, which speaks of environmental friendliness. Use thermal insulation can be in buildings of any purpose, even for the warming of children's rooms. The products have a positive energy balance. This indicates that the energy saved exceeds the energy costs of production.
Consumers enjoy more and durability. It is provided by a special structure, which guarantees the shape stability and rigidity. You can not be afraid of deformation of the plates, which do not shrink during the entire service life. Buyers especially emphasize that mineral wool copes well with the preservation of heat.
It has a low coefficientthermal conductivity. The material can be compared to a wall of a bar. The same amount of heat will pass through a 100-mm layer of insulation and a 440-mm layer of timber. These parameters can be compared with brick masonry, the thickness of which reaches 1960 mm.
Rockwool mineral wool is a heater thathas outstanding technical characteristics. For example, the coefficient of thermal conductivity is equal to the limit from 0.036 to 0.038 W / mK. These parameters are among the best among the heaters of the described class. The most commonly used thickness is 50 mm. Shrinkage does not occur even with prolonged use.
The structure is unique, itassumes a chaotic arrangement of fibers. This difference can be distinguished by comparing mineral wool with fiberglass - the last filament is almost longitudinal. This quality has a positive effect on rigidity and tear resistance. Fibers interact with each other, so the heater, even with a vertical installation, does not add up under its own weight.
The density of Rockwool mineral wool affectsthermal conductivity. The relationship between mass and volume is the reverse. The lower the density, the higher the thermal conductivity. This characteristic is equal to the limit of 35-37 kg / m3. In the production process, the material is processedwater-repellent oils, they provide hydrophobicity, which is expressed in the ability not to absorb, but repel moisture. This feature can be called unique, because in a moist environment the material does not collapse. Therefore, it can be used even in damp areas.
The insulation of "Rockwool" is quite highvapor permeability, it is 0.25 mg / (m · h · Pa). Thermal insulation lets air and steam through. This gives a positive effect, because the condensate does not accumulate during operation, and the walls breathe freely. A heater is also capable of performing soundproofing functions. The wave, passing through the layer of insulation, fades out, there is an absorption of sound.
Compressibility and bioinertness
The structure of the insulation is unique and hasa lot of air pores, so the material is easily compressed - from the original volume, it can change the size by 30%. Fibers have a certain melting point, so the material in the conditions of ignition will be able to protect the structures from fire, hindering the process of pore destruction. The insulation begins to melt at 1000 ° C. The insulator "Rockwool" is also good because it is not able to become a suitable environment for the life of living organisms. This applies not only to bacteria, but also to small rodents.
Rockwool's 50-mm mineral wool hasingredients are a strong binder component. The material for the thermal insulation of pipes, roofs and walls is used. It can become a part of construction and engineering industrial buildings, office buildings and residential buildings. Isolation can be used for internal overlaps.
