Why the basement - the coldest place in the house at any time of year

Sometimes, we ask ourselves why the basement is the coldest place in the house or how to make it so. And if there is no basement in a private cottage? What else can serve as a special multifunctional room intended for storage of winter spins, household utensils, sports equipment, accommodation of communications? What is the difference between a cellar and a cellar? The advantages and disadvantages of each of them are briefly described in this article.

Cellar or cellar?

Answering the question, it is important to understand the goal-setting, the purpose of a particular room. The basement is an underground non-residential part of the building. Often it is adapted to a workshop, utility room, garage and other useful area of free planning. It is characterized by durability, height in full growth of the person, absence of a natural sunlight, constancy of average daily and average annual temperature modes. When it is adjusted to a depth of 2 meters or less, the plug of the average annual temperature fluctuates within +5 - + 10ºС both in the heat and in severe frosts, even when nobody lives in the house and it is not heated. That's why the basement is the coldest place. Usually it is arranged under the kitchen, but it can pass along the perimeter of the whole apartment building.

The cellar serves only as a storage place for blanks. It is a kind of roomy refrigerator equipped with shelves and partitions. Can be equipped with a house in the same basement, or stand alone in the suburban area, often on dry slopes, elevations to minimize contact with groundwater. Compact in comparison with the "colleague", in some constructions you can only glance to get the can of the workpiece from the shelf. Its size will depend on the needs of the owner and the expected volume of blanks. Finance is less expensive.

Why is the basement the coldest place in the house?

The average student studying the basics of physics will be able to answer this question on the move: the cold air is heavy, dense, it goes down. This is the so-called natural convection. And the heat generated from the heating of the roof by the sun's rays does not reach the lowest room. But this is not the only possible answer.

Qualitative characteristics of the cellar

The basement requires significant investment in construction and finishing (about a quarter of the estimated cost of the entire house). Why? The basement is the coldest place in the house. In order for this statement to correspond to reality, it is necessary to build a structure qualitatively, requiring the determination of the soil structure, the implementation of land (for the preparation of a volumetric trench), drainage (for abstracting surface and groundwater), concrete works. Also it is necessary to make a clay lock of dense ramming, waterproofing sand and gravel cushion, to treat walls, floor (for example, bitumen emulsions). After all, the main enemies for such a room - water, dampness, mustiness, airiness of air. Hence, the main parameters that are able to extend the service life of the room are important: the resistance of walls to the pressure of earth rocks, destructive effects, high waterproofing and ventilation properties.

Thermal insulation - the basis of the basement for the basement

Why else is the basement the coldest place in the house? The answer to the question is a good thermal insulation, which provides protection of floors, doors, manholes, walls around the perimeter of the room from freezing.

The use of ultramodern insulating materials (polystyrene foam, fibrous cotton wool), as a rule, from the outside of the building, will avoid the formation of condensate, fungus and mold, and by 15-20% will save thermal energy that will not leave the house, be spent for heating Unheated room.
