Air exchange in a wooden house is also 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. The intake of fresh air is the key to health and longevity.
Ventilation in a wooden house. Is she needed?
Wood is a natural material that has many positive properties. Due to improper maintenance, the building can quickly rot, leaving the owners without a roof over their heads. A constant supply of fresh air will save the building from external factors. The safety of wooden logs or lumber is affected by:
- overdry or waterlogged;
- fresh air (not moisture);
- maintaining a certain temperature;
- elimination of burning, smells and moisture from the room.
Modern cottages differ from peasant huts for their impenetrability. Having removed 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 hoods. It was enough to open a small door in the furnace, and the air was replaced naturally. To ventilate the underground, floorboards were not laid tightly to each other. Through the cracks, warm air from the living room fell down, which was the key to preserving vegetables until next spring (for example, potatoes) and a long service at home.
Types of ventilation of a wooden house
Air in such buildings can be replaced as follows:
- Through the windows, doors, slots. Such air exchange is called natural ventilation.
- With the help of devices that can move air in space, as well as clean it or heat 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 go out. Exhaust ventilation is usually installed over gas stoves, which is turned on periodically during cooking. The supply ventilation system is designed for air intake from the outside. To speed up the ventilation process, special equipment is installed.
Floor and basement ventilation
During the construction of the foundation, it is necessary to pay attention to the production of openings through which air will enter the basement. Also, small holes should be made under the skirting boards. During cold weather, openings are closed to keep warm. In the summer - all openings are open.
Roof ventilation
Heated air rises up. The temperature difference leads to the formation of condensate, 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 by means of supply and exhaust ventilation. The scheme is simple. Air is forced into the channel and distributed into the rooms. Such a process is impossible without the use of special equipment (recuperator). On other branches, flows are removed from the premises into the external environment.
Such ventilation for a long time keeps the house from the influence of external factors. 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 our grandfathers built. The bathroom, kitchen and common rooms are now heated by gas and therefore can not be ventilated according to old rules, as in a hut. Despite the fact that the tree "breathes", it can not let air through it. It is only able to retain moisture in itself, which is why its rapid decay occurs. So if the indoor climate is high humidity, there is nothing to say about the long-term safety of the house.
How to install ventilation yourself? What do you need for work?
To install natural ventilation, it is necessary to build an exhaust duct. By opening windows and doors, the air enters the channel. To create such ventilation does not require special skills, design or expensive equipment. It is necessary to regulate air exchange independently by opening windows and doors depending on weather conditions.
Attention! In the private house where the stove will be installed, the ventilation duct is a pipe through which smoke from burning wood comes out.
For the installation of forced ventilation, fans will be needed, which will increase the speed of eliminating air flow 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 the dirty air to clean when the hood is turned on.
In what cases is a ventilation system design necessary?
A drawing or at least a schematic representation of the ventilation system will not be superfluous with the independent installation of channels for natural and forced air exchange. From the image it will become clear whether all the rooms, basement, bathroom, attic or roof of the building are taken into account.
If a supply and exhaust system is installed by specialists, then they must provide calculations and a draft of a future ventilation system before work. Only thanks to a clear image can we 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 the ventilation system:
- Calculate performance.
- Draw up a project, think over a place for installation of equipment, channels and air ducts. Planning should be done during the construction of the house.
- When erecting the foundation, leave room for vents.
- Place the channels in the walls (if provided by the project).
- Install valves, filters or a recuperator (depending on the type of ventilation).
- To carry out air exchange on the roof by installing holes for intake of fresh air flow and elimination of exhaust air masses.
Before starting independent work on installing an exhaust system, you should familiarize yourself with the basic rules for maintaining the premises, which are prescribed in SNiP 41-01-2003. The document provides conditions for the installation, operation of ventilation devices and requirements for the premises where the air exchange system is installed.
