Is it possible to isolate the best thermal insulation material?
With the help of insulation, the movement of air molecules, including warm air, becomes impossible and thanks to this the owner saves on materials such as mortar, brick and aerated concrete, with the help of which they tried to make it difficult to waste calories at home. During the operation of the building, heating costs are substantially reduced. When building it is important to comply with the standards of heat transfer.
All modern thermal insulation materials have a low thermal conductivity and are intended for such purposes: for the technical insulation of engineering systems( for example, pipes), to protect the structure, to protect against heating( cold rooms).
To date, new insulating materials are appearing on the market, but there are those who have earned their popularity for a long time. Mineral wool is a fibrous insulation, which is produced from mineral raw materials( dolomites, marls, balzates).
It is highly porous( almost 95% of the volume is in air voids), which is why it has high insulation properties. Wadding is the best thermal insulation material due to its availability, and also simple technology of obtaining and assembling. You can buy it at an affordable price.
Modern thermal insulation materials - briefly about the main representatives of
Steklovata is made from the same raw material as ordinary glass( lime, quartz sand and soda).Produced by manufacturers in rolls, shells and plates. Its advantages are similar to the advantages of mineral wool, but it is stronger than the basaltic analog, and also has better protection against sounds.
Cellular glass or foam glass is produced by sintering of gas generators( limestone) and glass powder. Its porosity reaches 90%, due to which it is famous for its thermal insulation properties. Given the comparative characteristics of thermal insulation materials, it should be noted thermal insulation concrete , especially gas-filled( cellular concrete, foam concrete and aerated concrete).They are based on lightweight fillers, such as polystyrene concrete and expanded clay concrete.
Cellulose wadding is a wood-fiber material, which in its structure is fine-grained.80% of it is wood fiber, a dry and wet method is used for styling. When choosing a wet method, it is necessary to blow out cotton wool when it is wet.
Its fibers contain pectin, which distinguishes it among others( if we compare the thermal insulation materials listed above) in terms of environmental friendliness.
Types of heat-insulating materials for different applications of
No comparison of heat-insulating materials is possible without determining which element under which coating is more suitable. When deciding to conduct a floor insulation, it is necessary to know that such a solution will ensure a constant temperature in the house. Comparing the characteristics of thermal insulation materials, it is possible to select for this purpose a coating that will withstand the constant pressure exerted on it.
Good compression performance is important. One of the requirements for the material is the preservation of the insulating properties, even if it penetrates the interior of the moisture, and the coating will be subjected to mechanical stresses. Often for insulation use keramzit , if there is an opportunity to fall asleep it when pouring the concrete floor. If your house has a basement, then for insulation of the floor you need to fix the insulation from the cellar or cellar. For this, the is used as a foam polystyrene .
For walls, the classification of insulation materials is somewhat different, it all depends on the place of application - inside or outside the room. To insulate the house outside , mineral basalt wool is ideal, which is distinguished by its durability, absence of deformations. Also, it does not compact and does not thin with prolonged use.
From inside the walls are insulated depending on the permissible insulation layer, sometimes making it big does not allow for the layout features. The most popular method is polystyrene or minidate , but these are the thickest versions. More modern - paint based on ceramics , the layer is required thinner, and it is easier to observe the tightness conditions. However, the choice of material is complicated by the fact that each option has its dew point, and if the place you are trying to cover exceeds the permissible value, your isolation will not bring any result.
To insulate the ceiling, the mineral wool is considered to be the undisputed leader, since it is easiest to put in the necessary amounts in the frame of the rafter system or interfloor overlappings, and almost nothing is threatened with such places( which could reduce the insulation quality).If you give up the convenience of installation and the cheapness of mineral wool, then slag or sawdust with clay could be the best means to keep the heat, but the volume and hardship of the work, and the high price of the material, still do not make them popular.
