Technological approaches to the device of insulatingcoatings are already quite firmly established. Manufacturers produce materials in the form of plates, panels, loose components, but the most promising is the foam filler. In the market, this material is known as a sprayed insulation. Unlike most conventional insulators, it provides almost 100 percent leak-tightness. And at the same time is not inferior in terms of strength. Foam insulation can be made by any home wizard using a suitable tool. This aspect is very conducive to the popularization of the material, although it also has certain shortcomings.
Unlike most insulating materials,the foam acquires a complete functional structure only after installation. The basis of the composition is formed by polyurethane, which, in turn, is formed during the mixing of the polyol and isocyanate. The resulting mass is sprayed onto the working area through the spray gun. The cooling procedure takes only a few seconds. On the one hand, this makes the wizard more efficient in carrying out work with large volumes of coating, and on the other hand, a high polymerization speed eliminates the delay of subsequent assembly activities.
It is important to note another specificA feature that is accompanied by insulation with foam based on polyurethane. From the moment of its application and until the final hardening of the insulator, the mass increases tens of times. In the same period, the adhesive bonding process takes place. It is for the possibility of organic fixing foam to different materials it is called a universal insulation. Also worth noting is the absence of seams and gaps in the structure that forms, which provides and waterproofing qualities.
A mounting foam of this type can be usedpractically for all building structures and surfaces, which can be finished with traditional insulating means. It can be floor covering, facade, roof, walls, ceiling, etc. It's another matter that there are different kinds of heat insulator, each of which is suitable for this or that area.
Under certain conditions, foam insulation can beproduce and in technical areas, in storage and hangars, where high humidity prevails. Spray trains are also handled by car trailers, which allows to ensure not only the preservation of heat, but also the tightness. But, as in the case of other heaters, the most common base formulations for interior decoration. They can even be sprayed by a layman.
This is the most popular type of polyurethaneinsulation foam. Such means are used both in everyday life and in professional construction. The features of the "family" Sealection include the possibility of technical alignment with respect to a variety of surfaces. For example, the insulation of a roof with foam allows one to cover several roofing structures at once, providing the same quality of connection. As a result, a monolithic base is formed in the form of an air parobarrier.
With regard to performance, the formulationsThis brand is strong, undemanding in care and harmless. It is environmental cleanliness that has largely caused the popularity of such funds among private house owners. The foam safety is explained by the fact that it uses recycled plastic components with ecological additives. In addition, the material has a good thermal conductivity. This is the optimum foam for wall insulation, as the formed insulation layer reliably protects the room from the cold bridges.
In this case we are talking about a rigidtwo-component foam with high density. This is a material with a greenish tinge. It has good adhesive properties, it does not have chemicals harmful to the environment and human health, and is also suitable for a wide range of applications. The main function of this composition is to create the optimal microclimate.
If compared with the previous representativeinsulation foam, the foam for heat insulation of the Heatlok Soy line helps minimize excess energy consumption. That is, if the main task of most heat insulators is to prevent heat leakage, in this case the material serves as a regulator. In rooms with such a substrate for finishing, you can count on the preservation of light cold in the summer.
Combining several functions for heat insulatorshas always been a common occurrence. The simplest natural insulation, even without special additives, also contributed to the preservation of the silence in the room. If we talk about sprayed compounds, from the point of view of noise insulation, then the most effective tool is Sealection. If it is required to make a slope in the direction of steam and waterproofing, the best option will be insulation with U-200 foam.
To some extent, any polyurethaneThe coating can act as a barrier to the formation and spreading of condensate. Prolonged contact with water or exposure to moisture is not recommended for such products. But the material U-200 is just designed for such purposes.
The material is applied by means of a specialequipment. Usually the set of this technical equipment includes a pneumatic gun and a compressor. There are also forms of delivery of the insulator, which are equipped with a spray can, is the best option for home use. Initially, the mixture is in a liquid state, so during processing it easily covers the most complex areas. By the way, it is in hard-to-reach places that work should begin. These can be ventilation passages, panel junctions, underground niches and other problem areas.
It is important that insulation with polyurethane foamwas performed under conditions of optimal temperature and humidity. In wet weather and even more so in the rain, it is not recommended to insulate the facade. On the other hand, in the heat at 50 ° C, first apply a thin layer, and when it hardens, proceed to a full treatment. After the final polymerization of the material, if necessary, it can be corrected for its mass, since during expansion the foam composition often exceeds the boundaries of the planned heat insulation zone.
Despite all the advantages, this material has been preserved andquite attractive value. Even budget foam assembly, the price of which is about 300 rubles per container with a capacity of 0.75 liters, provides a good result in terms of performance. In the market there are a lot of premium modifications from large manufacturers that sell products for 500-600 rubles. in the same format. But, as practice shows, the difference between price groups is small. Usually it determines only the external design and the availability of devices for spraying.
If it is planned to perform large volumeswork, it is better to contact specialists. These services will require a separate expense item, but you can count on the high quality with which the mounting foam will be applied. The price of spraying per 1 m2 varies on average from 400 to 600 rubles.
Users mark and worthy characteristicspolyurethane as a heater, and the convenience of its use. In particular, many homeowners emphasize that the very structure of the insulator and its spraying technology minimizes the risk of performance of insufficient coverage. In addition, users assure that the foam insulation is very hard to clean from the surfaces. If the material gets on the clothes, then, as a rule, it is thrown away. Therefore, during the spraying process, careful handling should be carefully restricted.
Segment insulating materials regularlyreplenished with new proposals. Manufacturers are faced with a choice: either to develop more technologically synthetic compounds, or to improve the quality of natural remedies, which is much more difficult and not always possible. In this context, foam for house insulation can be considered as a universal composition. It does not have a major drawback, for which users criticize artificial insulators - this is a high content of toxic substances. This fact in itself can be regarded as a separate dignity. At the same time, the sprayed materials do not lose their performance characteristics and the same artificial analogs, and natural thermal insulators.
