In the world of "global warming." But for some reason, in the autumn-winter period, alas, it does not get warmer ... “The economic walk around the planet” and yet, God knows what, crises. Therefore, prices for heat and natural resources are increasing and increasing ... What remains to us, the average man in the street?
How to create comfort and save heat in their own homes and apartments, provided that prices of coal, gas, oil and electricity are growing at a catastrophic rate? There is an exit. And pretty profitable. This is a house insulation.
Where is the problem and how to solve it
It is good when there are enough funds to “wrap up” a house, like a doll, in insulators from all sides (not only around the perimeter, but also from above and below). If the lack of funds a bit "confuses" the owners of the house or there are suspicions that not all parts of the house need insulation, there is a need to conduct a test. The so-called thermal imaging study. It will allow you to identify the most thermo-vulnerable spots in your structure.
Finding out the most "weak" places at home can only choose the appropriate method and material for insulation.
Warm ceilings in private homes have learned long and successfully. Manufacturers have in stock a lot of different types of insulation for the installation of the so-called "second" ceiling. From natural (wood, straw, clay and others) to synthetic (for example, glass wool, polystyrene foam).
Recently, not only in private houses and cottages, but also in apartments, more and more often they resort to the installation of a “warm floor”. For this, they use both heating (electrical) and various types and degrees of density of insulants for linoleum and laminate.
No less popular and often practiced insulation of windows and doors. Any insulation for windows is used: from paper and wool to foam rubber and greenhouse film. Rationally and partly effective. As for the front door, any known method is the right one. Although, at the same time, it has a destructive effect on the durability of the material from which the door or window itself is made.
In this case, it would be more rational to install modern windows or a door, the manufacturing technology of which initially provides for insulation from the penetration of dust and cold air from the outside and saving heat in the room.
As for the insulation for the walls, the conversation here will be a little more detailed and clearer, as it is often more important than the insulation of the front door, windows, floor or ceiling.
Insulation for walls. Where, how and why
It would be naive to believe that the density of the wall, which protects from the wind, is also impermeable to cold and heat. As from the street to the house, and in the opposite direction.
The greatest heat losses occur precisely through the external walls of the room. After all, their area is the largest percentage of the area of the entire building in contact with the street and external cold air flows.
There are three ways of wall insulation: internal, external and mixed (or combined).
To decide for yourself what kind of house you need to choose the type of insulation, consider a few of these options. The dew point, that is, the freezing point and accumulation of moisture condensate, is always in the center of the wall thickness during the cold season. As in the first picture.
In this scenario, the physical forces of nature about 80% of the heat leaves the room on the street, in its place comes about 40% of the cold from the outside. Even with a high heat of heating devices and high energy costs in the rooms of the building, it turns out to maintain a “normal” temperature.
The use of insulation from the inside of the room at 50-60%. That significantly saves the family budget.
There is certainly one "but." With the accumulation of moisture in the insulation from the inside there is a big risk of the formation of fungus in the wall. Therefore, this type of insulation is only a temporary measure.
Outdoor insulation at home is much more efficient, although it also has the risk of mold or fungus, if you do not follow all the rules for its installation and installation.
Heat saving is the same as with internal insulation. The room receives the greatest protection against heat loss from the combined type of warming. Moisture generated from the collision of warm and cold air currents transfers the dew point to the external insulation, and specifically to the air cushion. As shown in the third figure. And the risk of formation of a destroying wall of mold or a fungus harmful to human health becomes almost zero.
What option of warming the living space to choose - everyone's business. But practice has proven that the combined method of home insulation is most effective, both in terms of heat conservation inside the building, and in terms of security for the building itself.Providing him with not only protection from climatic influences from the outside, but also eliminating the occurrence of harmful microorganisms.
Something about home insulation materials
For high-quality home insulation, first of all, it is necessary to choose the right materials, both internal filler and coating.
The choice of material for home insulation depends on many factors. For example: the climatic conditions of the region, the material from which the house is built, the statute of limitations of construction and the thickness of the walls. Together, these factors form the scheme by which the mechanism for assembling insulation layers will be developed.
It should be noted that the inner, basic layer of insulation provides at this time two well-proven material: polystyrene foam and mineral wool.
Both one and the other material have their own positive and negative characteristics. But, we live in such a century. Of the two evils, we choose the least and continue to live happily. Regarding our topic “home insulation” is also warm.
