The Finnish manufacturer Paroc has been manufacturing basalt mineral wool for more than 50 years. This insulation is widely used for thermal insulation of objects for various purposes. The main raw material is stone fiber. Due to this basis, the product also meets fire-retardant requirements.
Consumer Reviews
Quite often, recently, customers choose products of the company Paroc, the insulation of this brand has excellent technical characteristics. According to users, installation can be done without special tools and skills. The plate takes the necessary shape, and its size is permissible to change with a conventional knife. No effort is required, but no dust is generated.
Buyers claim that after carrying out insulation work, the fire safety of the building remains at its best. This is because the melting point of the fibers is 1000 degrees. The material is resistant to moderate acidic environments, solvents and oils, and also contributes to high quality insulation. The canvas is not affected by temperature extremes, so compression and expansion are not typical for them.
Hygroscopicity
Choosing a product brand Paroc (insulation, in particular), you should read more in detail the reviews of people who have purchased this material and managed to experience it during operation. So, hydrophobic properties provide insignificant absorption of moisture by canvases. If it gets wet, after drying, the cotton wool will restore its thermal insulation characteristics. Home craftsmen note that the structure provides the most tight fit to the surface of structural elements of buildings. Among other things, you can count on the fact that the material throughout its life will retain its original shape.
Main characteristics
By purchasing Paroc insulation, reviews about which are often quite positive, you get the opportunity to create the optimal microclimate for the person inside the building, thereby significantly reducing heat loss. The service life of buildings is increasing, as is their energy efficiency. The low density of the material is explained by a random alternation of fibers, between which air is contained. This structure provides low thermal conductivity, which contributes to thermal insulation.
Experts note that the thermal resistance of basalt-type cotton wool can be compared with wood. In this case, the thickness of the materials will be 100 and 400 millimeters, respectively. At the same time, brickwork with the same characteristics will have a thickness of 1800 millimeters; as for concrete, this figure increases to 4700 millimeters.
Thermal conductivity
When choosing a Paroc insulation, you should consider the characteristics in advance. Among the main ones, it is necessary to highlight the thermal conductivity, which varies, depending on the state. Under wet conditions, this indicator increases, due to the fact that water increases the area of contact between the fibers. For this reason, when choosing thermal insulation, it is necessary to take into account the waterproofness.
Fire and environmental performance
Basalt rock acts as the main raw material for the manufacture of the described products. For the most part, the material consists of stone threads and a certain amount of various additives. This indicates that the plates do not support active combustion. After the temperature reaches a limit above 1000 degrees, the canvas can receive maximum damage. Paroc is a heater that meets the stringent fire safety requirements, which is why it can be used as fire insulation and fire protection without restriction in structures for various purposes. When choosing products of the brand Paroc, the insulation of this manufacturer you should consider in more detail. After reviewing the characteristics, you will understand that the material does not have a negative impact on human health. It is biologically stable; pathogenic microorganisms cannot form on its surface and inside the structure. Stone wool does not contain harmful substances such as asbestos, this allows us to classify the material as a group of particles that are safe in emission.
Hydrophobicity characteristics
The described material can show high efficiency in the dry state. But sometimes it is impossible to provide and guarantee optimal conditions of use. That is why you should know how the material behaves when exposed to moisture. Stone fibers have natural water repellent characteristics. During the manufacture of cotton wool, additives are added that enhance hydrophobicity. This allows you to expand the scope of use, providing the possibility of installation in different climatic zones. When the material is immersed in water for 2 hours, the volume of water in the material will be 1% or less. If you increase the duration of the dive to 2 days, then the volume of water can be equal to three percent. Vata has a high vapor permeability, so it almost always remains dry. During the operation of the building water vapor will form, which will freely pass through the structure of the material.
Heater Paroc, whose density is 33 kilograms per cubic meter, is resistant to mechanical stress. The material is not able to create a favorable environment for the development of corrosion processes. Organic materials, as well as solvents and alkalis, which are not capable of causing damage to the structure or properties, can affect the surface of the material. Due to the fact that the insulation has a neutral environment, it is successfully used when conducting insulation works in the field of pipelines, frame structures and ventilation facades.
Characteristics of insulation Paroc Extra
Heater Paroc Extra, the characteristics of which will allow you to understand whether to purchase it, is made on the basis of diabase or basalt. You can use it when warming the pitched roof, walls, floors and partitions. The sizes of the plates vary from 1200x600x50 to 1200x600x200 millimeters. In the first case, the price per package is 800 rubles, while in the latter case - 900 rubles. For a cubic meter, the consumer will have to pay 1,580 rubles for the dimensions of the slabs that were mentioned in the first case.
The density of the plates is 35 kilograms per cubic meter, while the thermal conductivity is 0.036 W / m * ° C. The dimensions of the plates are designed taking into account the standard dimensions of the frame structures of facades and roofs. This allows for ease of installation, and also ensures that there is no need to use additional fasteners. During installation, the plates are laid as tightly as possible, which ensures close contact, excluding the conditions for heat leakage and the formation of cold bridges. Among the advantages, a high degree of elasticity, which manifests itself in the absence of a constant load, should be highlighted.
Consumer Reviews
The Paroc Extra insulation has a stable density over the entire thickness, and after installation the material does not shrink, the structure is preserved in its original form, which eliminates the deterioration in the quality of thermal insulation over time. The plates are made in such a way that they have a clearly formed elastic edge, which, according to most users, is an important quality to ensure a tight fit of the plates to the frame. When purchasing a Paroc Extra insulation, you should read reviews about it in advance. Perhaps they will allow you to understand in favor of what material to make a choice. Consumers like that in the composition of the material there are hydrophobic additives that spread evenly throughout the thickness. This provides hygroscopicity. Subject to installation technology and operating conditions, the service life of the material can reach 50 years.
Conclusion
Having visited the store, you can find several varieties of insulation Paroc. Among them, Linio-15, which is characterized by increased density, should be distinguished. This indicator can vary from 96 to 120 kilograms per cubic meter. If you also decided to choose Paroc products, insulation, in particular, you should know that in the assortment you can also find the FAS 3-30 variety, which is used to equip facades. The material is a hard stone wool in the form of individual slabs.
