Why do I need ventilation systems in a private home? For those who still doubt whether the installation of ventilation in a private home is necessary, here is a simple example. Air that is suitable for breathing contains about 60 percent oxygen. The remaining 40 are gases that either do not affect the body, or cause harm to it .

In addition, harmful bacteria and viruses actively multiply in a room with insufficient air circulation. Many parents who are too zealous to cover up their children and close all the Windows and vents, can not understand why their child, however, is constantly ill. The answer is simple – in the stale atmosphere of a sealed room, disease-causing organisms feel excellent and successfully attack their prey. They take as their allies the smallest particles of dust that freely enter the tissues of the lungs and nasopharynx, settle there, provoking a cough and a constant runny nose.
Sometimes diseases take a chronic form. But to solve all these problems, the ventilation device in a private home will help, and the entire structure will cost much less than a full set of medicines for the treatment of family members. In addition to harm to the person, the tightness of the premises causes damage to the structure itself. The lack of normal air exchange leads to the growth of mold and fungus, the destruction of all natural finishing materials and walls. Excessive humidity affects the plaster, which cracks and flakes off from the base. Ventilation projects of private homes provide for the specific purpose of each room and create the necessary microclimate in the bathroom, kitchen, boiler room and living rooms.
Installation of natural ventilation in a private house with your own hands should be considered at the design stage of the house. During the construction of walls, ventilation shafts are laid or pipes are fixed, if the house is not made of bricks. The system works effectively due to the difference in air pressure and temperature inside and outside the building . Advantages and disadvantages of the system
Another important point – the exhaust pipe must be sufficiently insulated. If it is made of brick, then the recommended thickness of masonry is two and a half bricks. Metal and plastic hoods are insulated with mineral wool. This is necessary to ensure that the air duct does not cool down on frosty days and effectively continues its work.
The height of the vent channel is selected relative to the height of the skate. To determine the size of the pipe, you need to draw a horizontal line from the ridge, and then another straight line with a rise of 10 degrees. The upper point will be the value you are looking for.
