The fundamental difference between the ventilation device in the bathroom of a wooden house is the probability of deformation of the ventilation ducts when the house shrinks. Therefore, when laying water supply, sewer pipes and ventilation ducts, it is important to consider it.
Installation of ventilation in the bathroom
In no case should you neglect the installation of ventilation in the bathroom of a wooden house. After all, wood here is subjected to constant exposure to water, which is fraught with the appearance of a fungus, darkening of the surface, deformation and rapid destruction. When installing a forced ventilation system for the bathroom of a private house, fire safety measures should be taken into account. These include: gaps between the wooden surfaces of the house and ventilation ducts, as well as fans created specifically for bathrooms and rooms with high humidity. They are developed using special technologies and have the highest degree of fire safety.
All ventilation equipment is most conveniently mounted in the attic.
Installation Precautions
- Boxes and pipes are never installed directly on wooden boards; for this, special holders are sold;
- All components of the bathroom ventilation system at home are made of soft, non-flammable materials;
- To pass the ventilation duct through the wall, it is necessary to equip the compensation hole. If the house shrinks, the pipe will not suffer;
- Ventilation of a bathroom in a private house is certainly supplied with fire dampers, blocking the access of oxygen in case of fire.
Bathroom fan
It is extremely important to choose a special fan for the bathroom. They are made waterproof, which is the requirement of firefighters. But that's not all. In order for the ventilation of the bathroom at home to be effective, it is important to correctly calculate the power of the fan.
It depends on the volume of air in the room. The height of the room must be multiplied by the length and width, the resulting figure is multiplied by the desired air exchange (the frequency of changing the air in the room in one hour). For ventilation of a bathroom in a private house, the air exchange rate should be 8/10.
The result of these calculations will be the fan performance.
When installing the ventilation of the bathroom of a private house, one should also take into account the fan switching scheme. It can be connected to a common bathroom lighting system. It is convenient to connect the fan through the sensor and it will turn on at a certain level of humidity.
