Air exchange in a wooden house is as necessary as in any other building. Due to ventilation in the room, excess moisture does not accumulate and mold and fungal formations do not form. Fresh air supply is a guarantee of health and longevity.

Wood is a natural material that has many positive properties. Due to improper care, the structure can quickly rot, leaving the owners without a roof over their heads. A constant supply of fresh air will keep the building from external factors. The safety of wooden logs or beams is affected by:
- overdry or waterlogged;
- fresh air supply (not moisture);
- maintaining a certain temperature;
- elimination of burning, odors and moisture from the room.
Modern cottages differ from peasant huts in their impenetrability. Having eliminated all the cracks, air exchange does not occur. Also, replacing the Russian stove with gas heating affects the condition of the walls, floor and ceiling.
For reference! In the old days, buildings were built without forced draft. It was enough to open the small door in the oven, and the air was replaced naturally. To ventilate the underground, the floor boards were not placed tightly to each other. Through the cracks, warm air from the living quarters fell down, which was the key to the safety of vegetables until next spring (for example, potatoes) and a long service at home.
Types of ventilation of a wooden house
The air in such buildings can be replaced as follows:
- Through the vents, doors, cracks. This air exchange is called natural ventilation.
- With the help of devices capable of moving air in space, as well as purifying or heating it. This type of ventilation is called mechanical ventilation.
For the ventilation system, at the initial stage of construction, channels are installed through which air will escape to the outside. Exhaust ventilation is usually installed above gas stoves, which is turned on periodically during cooking. The supply ventilation system is designed to supply air from the outside. To speed up the ventilation process, special equipment is installed.
Floor and basement ventilation
During the construction of the foundation, attention must be paid to the production of openings through which air will enter the basement. Also make small holes under the skirting boards. During cold weather, the openings are closed to keep warm. In summer, all openings are open.
Roof ventilation
The heated air rises upward. The temperature difference leads to the formation of condensation, which leads to gradual decay. To avoid such a nuisance, the attic should be equipped with ventilation at the base of the roof.
Ventilation of other rooms in a wooden house
Air exchange in all rooms is carried out using supply and exhaust ventilation. The scheme is simple. Air is forced into the duct and distributed throughout the rooms. Such a process is impossible without the use of special equipment (recuperator). Through other branches, the streams are removed from the room into the external environment.
Such ventilation keeps the house from external factors for a long time. However, the high cost, periodic maintenance and noise are not in favor of such a system.
Does the air exchange of the walls exist or not?
A modern private house cannot be attributed to those buildings that were built by our grandfathers. The bathroom, kitchen and common rooms are now heated with gas and therefore cannot be ventilated according to the old rules, as in a hut. Despite the fact that the tree "breathes", it cannot let air through itself. It is only able to retain moisture in itself, which is why its rapid decay occurs. So if the microclimate inside the room is high humidity, there is nothing to say about the long preservation of the house.
How to install ventilation yourself? What do you need to work?
To install natural ventilation, it is necessary to build an exhaust duct. By opening windows and doors, air is released into the channel. To create such ventilation does not require special skills, project or expensive equipment. You will have to regulate the air exchange yourself by opening windows and doors depending on weather conditions.
Attention! In a private house, where the stove will be installed, the ventilation duct is a pipe through which the smoke from burning wood comes out.
To install forced ventilation, you will need fans that will increase the rate of elimination of air flows from the room. The inflow is ensured by open windows and doors.
For supply and exhaust ventilation, where you do not have to open windows and doors, you will need heat exchangers that will independently change dirty air to clean air when the hood is turned on.
When is a ventilation system design necessary?
A drawing or at least a schematic representation of the ventilation system will not be superfluous when self-installing channels for natural and forced air exchange. From the image it will become clear whether all rooms, basement, bathroom, attic or roof of the building are taken into account.
If the installation of the supply and exhaust system is carried out by specialists, then they must provide calculations and a project of the future ventilation system before work. It is only through a clear image that you can understand whether the equipment will work efficiently enough. The main characteristic that you should pay attention to when choosing a recuperator is its performance.
Installation steps
To install a ventilation system, you must:
- Calculate performance.
- Draw up a project, think over a place for installing equipment, channels and air ducts. The planning should be done during the construction of the house.
- When erecting the foundation, leave room for air vents.
- Place channels in the walls (if provided by the project).
- Install valves, filters or a recuperator (depending on the type of ventilation).
- Carry out air exchange on the roof by installing openings for intake of fresh air flow and elimination of exhaust air masses.
Before starting independent work on the installation of the exhaust system, you should familiarize yourself with the basic rules for maintaining the premises, which are spelled out in SNiP 41-01-2003. The document provides the conditions for the installation, operation of ventilation devices and the requirements for the premises where the air exchange system is installed.
