Normal temperature inside the house, especially during the cold winter season, is the main condition for a comfortable stay in it. It depends on many characteristics of the house, one of which is the presence of a blind area around its outer perimeter. Experienced craftsmen who know about all the negative aspects of the absence of a blind area, recommend that you always perform this part of the work when building a house.
There is opinion that it is enough to warm only the foundation. Consider that the option is more acceptable due to lower material costs.
In many climatic zones of Russia, the soil during the winter period freezes to a sufficiently decent depth. As a result, the walls are frozen at the base of the house, the foundation. This leads to a decrease in temperature inside the structure, which significantly increases the heat loss.
A warm blind area around the house allows the earth to keep its temperature warmer over the summer. As a result, the foundation and walls of the basement store heat better. The real facts confirm that after warming the blind area around an unheated house in the winter time, the temperature inside it rises by about 60C. Consequently, one-time costs for the construction of a warm blind area will save on heating the house for many years.
A warm blind area is an adjacent walkway, the width of which should ideally reach 1.5 m. It performs the following functions:
The owners of private houses note the negative facts that are caused by the absence of insulation. Approximately five years after the start of the construction of the house, there is a gradual extrusion, destruction of the foundation. Therefore, blind area can significantly extend the life of the structure.

Choice of exterior coatings It is produced depending on the operational properties of the material and the design preferences of the owner. The most popular coating options are:

The insulated blind area around the house, unlike normal, lightweight version, involves the use of additional insulation. The quality and performance characteristics of a blind area of this kind depend on the choice of materials that should have:
Not all materials for insulation meet similar requirements. The following types are most commonly used:
The listed materials are in various degrees suitable for performing such work.
It is a rounded sintered clay granule, characterized by a low specific gravity. Thermal insulation qualities correspond to a high level.
Insulation with expanded clay is the most profitable option in terms of material costs. The only drawback of the material is that it is quickly impregnated with moisture, so work is required to be done with an additional layer of high-quality waterproofing material. The thickness of the expanded clay layer in the blind area must be at least 50 cm.
Expanded clay is sold in packaged form or in bulk.
The material is used, as a rule, during independent insulation work. This is a very easy, inexpensive, widely available option. Its disadvantages:
Professionals do not recommend using foam in works, especially for installing it in the ground. When choosing foam insulation as a heater, it is always used at the same time as high-quality waterproofing.

Effective insulator, used for insulation of all parts of the building. Contained in cylinders under pressure, applied to the surface by spraying.
In the presence of certain devices suitable for the blind area, made with his own hands.
Extruded foam polystyrene, or expanded polystyrene, is produced in the form of slabs of standard sizes, is the most expensive, but also better material. The most suitable for the properties, the most convenient option for the construction of a warm blind area around the house. The joining of the plates is carried out by the groove-ridge method, which ensures the maximum tight fit of the edges. It has the following advantages over other types of materials:
The correct material for warming the foundation and blind area provides protection of the underground part of the house from freezing.
If you wish, you can build a warm blind area around the house with your own hands. The main thing is to understand how to warm the blind area around the house, and in a certain sequence to perform all the steps. However, for an excellent result that you can be satisfied with for many years, you should contact the experts. It is necessary to take into account, the work will require considerable physical effort.
There are several types of blind area. Rigid construction involves the implementation of the upper, outer layer of concreting or asphalting. The concrete mix is poured on the reinforced lattice superimposed on successive layers of waterproofing materials, sand, gravel and insulation. Reinforcement provides resistance to soil movement. Pouring a concrete screed along the entire perimeter of the house is always done at a time. This is the main condition for obtaining a reliable, unified design. Interruptions in the pouring process allow voids to form, which are then filled with water. At negative temperatures, the water freezes, the concrete cracks and collapses.
Soft construction is a more reliable variant of warming the socle and foundation of a building built on mobile soil. Such an erection is resistant to ground layer fluctuations.
As a heater choose any of the above materials. It should be noted that to work with polyurethane foam requires special expensive equipment.
When a warm blind area is constructed around a house, all stages are carried out sequentially according to a proven method. When constructing a blind area, it is necessary to pay attention to significant nuances:
When choosing a soft blind area, road tile or stone is laid.
