Ventilation in a wooden house - types and device
The house of wood is fundamentally different from other buildings, thanks to its natural energy. It is not possible to reproduce the real forest scent by any chemical substitutes, in addition, it is much easier to breathe in it. The question arises, if the wood itself can control the atmosphere in the room, is there a need for ventilation in a wooden house?
If you are also interested in this, you should read the article to the end.
Despite all the positive aspects of living in a wooden house, there are a few troubles that you will have to face if the ventilation in it will work poorly. Experts do not just advise, but strongly recommend not to postpone its installation for a long time, but it is best to do it simultaneously with the construction of housing.
Why ventilation in the house of wood
If you imagine yourself from films or cartoons, an old wooden hut, its center was often a large Russian stove, and curtains were used instead of walls. In this case, there was no point in worrying about the ventilation, as the stove itself was an excellent vent.
However, for a modern wooden house, which is often composed of laminated veneer lumber, this approach is unacceptable. In this case, we get a "box", which is a tightly knit chest, in which there is no room for cracks and drafts.
Due to the material and the structure itself, there is no natural ventilation in the building. Air masses stagnate, which negatively affects the atmosphere in the room.
Our task today is to tell about what kind of ventilation in a wooden house can be used, and also to show it clearly, depending on certain conditions.
We make a microclimate independently
If you have at least a little experience with construction tools, the installation of ventilation ducts will not seem too complicated.
To facilitate understanding of the process, it should be divided into several stages:
- The design of ventilation in a wooden house should be carried out in accordance with the air exchange norms approved by the SNiP:
| Kitchen |
|
| Bathroom | In one hour, the supply and discharge of air should be 50 m ?. |
| Bathroom | It all depends on its volume, but the average is 30 m? / H. |
| Utility room | Here the average is 15 m? / H. |
| Living room | In one hour, the ventilation system in a wooden house should provide air exchange on average 30 m ?. |
Tip: The above parameters are average, so the final result of the calculation of the ventilation system will depend on the layout of the house.
- Install the ventilation channels and mount the air ducts according to the scheme. If something goes wrong with you or causes difficulties, it is better to contact a specialist immediately at this stage, otherwise the cost of rework can be high.
- Be sure to check the performance of the entire system and its individual elements, finding problems and deficiencies, immediately fix them.
The easiest way is to use natural ventilation.
It can be said that this option attracts many with its cheapness and simplicity.
However, even here there are some nuances that must be taken into account.
- Begin its arrangement with the basement, so that the fresh air first gets here first. To do this, do not forget to make your own hands in the foundation - vents that need to be made under each wall of the house during construction.
We recommend organizing an air supply on the north side at the level of the basement, since from there it is cooler, which will make it possible to increase the thrust. It is not necessary to make the inlet duct in each room; leave only a gap of 15-20 mm under the inner doors.
This will be enough for the fresh air to freely penetrate into all the rooms and force out the waste through the hoods under the ceiling in each room. For beauty, you can cover them with decorative grilles. Be sure to make the output of each of them above the level of the roof.
Tip: install in the channels for the passage of air valve or plug with which you can control the rate of air exchange.
- When using a natural ventilation system to make for each channel its own output, and not to combine them into one. You can’t save a lot of money, but in it there can be a reverse thrust with a strong wind, spreading, for example, sewage odors in all rooms.
Also the thrust force can be affected by:
- height of the ventilation pipe;
- section of the internal channel;
- configuration and number of turns;
- insulation hoods.
Tip: since natural ventilation is highly dependent on the temperature difference between the inside and the outside of the building, in the summer period it is necessary to ventilate rooms through open windows more often.
- Understanding how to make ventilation in a wooden house, when choosing materials for ventilation channels, we recommend to stay on metal or plastic, the inner walls of which are very smooth. This will not create additional difficulties for the passage of air.
Note! Ventilation channels in a wooden house should not be narrowed at the joints and not have obstacles inside.
- Do not forget also about the ventilation of the space under the roof.. For example, in the attic you need to do the same, as in other residential premises, in the non-residential attic ventilation can be carried out through special holes in the roof.
Mechanical exhaust ventilation
In large or complex in the planning of the houses is not always the air naturally can freshen the atmosphere. Therefore, in such cases, you should pay attention to its forced flow using an electric fan. After its installation in the mouth of the exhaust channel, the exhaust power will increase significantly. This way is justified in the bathroom or in the kitchen.
The device must be selected according to the diameter of the ventilation channel in which it is to be mounted. You should also calculate the pre-power (how to do this can be found on the pages of our site) to be effective. Sometimes he has to help install a fan too.
Tip: connect the fan start to the light switch in the bathroom, it will stop its work after the light bulb is turned off.
As with natural ventilation, we do not recommend combining exhaust ducts from different rooms into one.
Forced ventilation
In addition to natural ventilation and the use of an electric fan, there is another way to effectively freshen the air in the room. You need to equip a ventilation system that also provides enhanced exhaust. This device is able to provide full air exchange in the house, from the foundation to the attic.
It is intended for:
- supply of fresh outdoor air;
- filtering the supplied air and cleaning it from dust;
- preheating of the air flow passing through the channel;
- removal of polluted air to the outside.
Tip: order the individual elements of the system in the already assembled form, so you can facilitate your work in the future.
Usually the kit consists of:
- duct fan for trapping air outside;
- electric heater for heating the air masses during the cold period;
- dry summer air humidifier;
- noise suppressor, to not feel the vibration of the fan;
- filters that prevent dust from entering the system.
Also used automation control and management. Installing the system is best in the attic of the house.
Conclusion
It became clear from the article that even in a wooden house a ventilation system is needed, but which of them - natural, combined or forced-air and exhaust will be better, you can decide for yourself or ask a specialist about it. Install the first two will not be difficult, with the third may be problems due to the installation of certain components and elements.
In any case, ventilation in a wooden house will help make the rooms in it cleaner and more comfortable.
