Why do we use insulation? Obviously, so that the temperature in the house is comfortable and the heat does not evaporate. Everyone understands this. But the fact that the insulation does not heat is not known to many.
Don't believe me? Check it yourself! Take an ordinary thermometer and wrap it in insulation. Even after a few hours, its readings will not increase, the thermometer will not heat up.
In reality, insulation is not a source of heat, it is intended to preserve it. If you touch the insulation, you can feel the warmth. However, this will only be a reflection of the heat of the human body. Unfortunately, many cannot come to terms with this fact, and they begin to use insulation (polystyrene, expanded polystyrene, etc.) literally everywhere.
I can argue that in the absence of a direct source of heat, the use of insulation is useless. After a while, the structure will still freeze through and through.
What happens if the thermos is left for a long time at sub-zero temperatures? Naturally, it will soon lose its main function - it will cease to store the heat released by water. Several hours will pass, and instead of water, there will be ice in the thermos.
The conclusion is this: in the presence of insulation, it becomes easier to keep heat in the home only if there is a heat source inside the house that works regularly.
Some craftsmen use insulation in unthinkable places. Don't repeat their mistakes!
1. There should be no insulation inside the house
Having decided to insulate the dwelling from the inside, the household members with their own hands reduce the service life of the walls. The house will not get warmer, on the contrary, the walls will freeze faster, since moisture accumulates under the insulation layer. The heat will go away from the home, but the dampness will remain. In such conditions, no finish will last long.
2. Partial house insulation
Thermal insulation of houses is a necessary measure. When laying the insulation on the walls of the building, the seams of the slabs are minimized. At the same time, the slabs should cover the entire area of the house, fit well to the outer walls. If you insulate the structure only partially, this will not give any effect.
3. You need to insulate the foundation correctly
In this case, you need to proceed from the ultimate goal of the activities performed. If there is a basement in the building, the foundation support unit will be located lower than the ground begins to freeze. Then the use of insulation will only help save the budget when heating the basement floor.
In the absence of a basement, the foundation can be of different types, including shallow and deep foundation. In the first case, the bearing unit is located where the soil freezes, and therefore one cannot do without warming both the foundation and the soil.
If you lay a layer of insulation under the blind area, the risk of heaving is reduced to zero. In addition, the material will retain heat from both the building and the ground. To increase the effect, you can make an extra layer.
In the case of a deep foundation, the earth does not require insulation. The material must be selected based on the climatic conditions of the region where the house stands. If warm weather prevails, and winter is not characterized by severe frosts, then you can do without warming the foundation, it will be enough to make waterproofing.
If the climate is cold, then it is advisable to insulate the foundation, otherwise the underground of the building will freeze through, fungus and mold will appear on the walls and floor.
4. Communications should be warm too
People often miss this moment and do not pay due attention to the laying of communications. It is best to hide wires and pipes in a special insulation. But many, in order to save money and time, use extruded polystyrene foam, which is simply laid on top of the communications.
As a result, the pipes are not kept warm, the cold will easily bypass the insulation, and the communications will freeze.
