Given the high speed of construction and the relatively low cost of construction work, frame houses began to quickly gain popularity. Such designs can have the most various forms and possess a number of advantages. However, the use of airtight materials and plastic windows for house insulation requires a proper ventilation system. Possible option – ventilation in the frame house with your own hands. The layout and installation of a simple ventilation system can be performed independently.
Ventilation in the frame house with their own hands. Scheme, installation and video methods of ventilation
Houses built by frame assembly, consist of a wooden frame and sandwich panels. Inside and outside the wall is subjected to finishing or cladding. In the window openings install plastic windows. All this in the complex makes the house perfectly leakproof. Traditionally, the design of such structures takes into account the presence of ventilation. If it is not provided, it will be uncomfortable and even dangerous to be in such a house.
The materials used in the construction of frame houses are not able to absorb moisture generated in the process of human life. In the houses of old buildings this was achieved due to the lack of complete tightness of wooden windows and doors. If the frame house is not equipped with ventilation, dampness, mold and fungus will settle there forever. Check out the video about the dangers of mold to human health.
Ventilation in the frame house depends on the purpose of the building. If we are talking about a dacha small house, where only seasonal living is expected, the windows and doors open during the warm period will serve as ventilation. For a toilet and a bathroom, a small window is arranged or an uncomplicated natural ventilation system is mounted by hand. In country cottages, where permanent residence is planned, in the premises of the bathroom and kitchen should be made exhaust channels with forced pitch.
If the cottage is being built with his own hands for permanent full-fledged living, then at the construction stage there should be a scheme for proper ventilation in the frame house. Experts believe that the most appropriate ventilation device in a frame house is a forced ventilation system using heat recovery. She will allow to keep the necessary air temperature even when airing with the help of open windows. Video ventilation in the frame house with their own hands probably will be found in the network.
Let’s try to figure out how to make ventilation in frame houses. The natural ventilation system is characterized by the flow of fresh air through the windows and doors, and the exit of the used air through the ventilation channels in the technical rooms (kitchen, bathroom, bathroom). This is due to the difference in air pressure inside and outside the room. Taking into account the fact that the frame house is a hermetic structure and windows are installed in it, the doors of which fit snugly to the frame, natural ventilation will be weak, or even completely absent.
Arrange ventilation in the frame house with your own hands, you can use the supply valve. Ventilation ducts can be made by hand from plastic pipes. The inlet valve provides fresh air into the room. You can get acquainted with the device of the wall inlet valve by watching the video.
Outside, it is locked with a grill to prevent foreign objects from getting inside the channel. Inside the valve of the natural ventilation of the frame house, a filter is installed for the primary treatment of the air and the silencer. The flow of incoming air is regulated by a damper. Air inlet valve – the device is quite simple and can be easily mounted by hand. To do this, it is necessary to make a through hole in the wall of a suitable diameter (50-130 mm). Then insert into it a pipe equipped with sound insulation, a filter and fix the grille and damper with your own hands.
Helpful advice! The natural way to ventilate frame houses is ineffective. Its use will not be able to fully prevent the formation of mold and mildew.
In order to ensure good traction in the warm period, when the temperature of the outside and inside air is the same, the inlet ducts of the service premises are equipped with fans. If necessary, you can install moisture meters that will automatically turn the fan on and off.
You can familiarize yourself with the ventilation scheme of a frame house with the natural principle of ventilation.
It should be noted that the natural ventilation system in frame houses, is effective only in the case of small-sized buildings.
On the Internet you can easily find the video “How to make ventilation in frame houses.”
Much more effective are forced ventilation systems in the frame house. It’s quite difficult to equip such a system with your own hands. In order to make the calculation, it is better to invite a specialist. A professional will tell you how to properly do the ventilation of a frame house.
Types of ventilation, advantages and disadvantages of ventilation systems, their device. The value of ventilation. The main parameters of ventilation systems. The main components of the ventilation room.
Forced ventilation works through the use of supply / exhaust fans, providing fresh air and the withdrawal of contaminated. The design of forced installations and its equipment makes it possible to regulate the incoming flow, purify the outside air from dust (coarse / fine cleaning), and warm it up to a comfortable temperature.
There are several methods of artificial ventilation:
- exhaust ventilation method (due to the forced removal of air, its fresh flow through the inlet valve enters the room); the inlet ventilation method (in this case, the air is artificially sucked in, displacing the exhaust air through the exhaust ventilation channels);
- forced-air and exhaust ventilation method (with the help of such ventilation, air is forced and removed forcibly);
- forced ventilation with heat recovery (this system heats the incoming flow by installing a heat exchanger, thus the room receives additional heat).
With certain knowledge, you can develop a ventilation scheme in a frame house with your own hands. According to design experts, the design of a frame house is such that an artificial ventilation system can provide proper ventilation in it. Ventilation in such a system occurs through ducts, is regulated by the control unit.
The design of the air-exhaust system consists of the following elements:
- air intake grille;
- air valve (stops air flow in case of shutdown of the system);
- filters (protects the system itself and the air from pollution);
- air ducts and air distributors;
- control (device for adjusting, controlling and controlling all elements of the system).
The air flow through the air intake penetrates into the system, there it is subjected to filtration. Already cleaned, it passes through the air ducts and through the air distributors into the rooms of the house.
Helpful advice! When assembling a combined ventilation system on your own, it should be noted that in cold time, incoming air will be cold and will cause a decrease in the temperature in the room.
Supply and exhaust ventilation system is a rather complicated duct system. Practically do it yourself and install it can be guided by the scheme and the project for housing construction. Important in the arrangement of such ventilation is the correct selection of material for ducts.
The obligation to ventilate the underfloor space of a frame house is due to the following reasons:
- preventing rotting of the wooden floor structure due to moisture and dampness;
- preventing mold and mildew;
- elimination of unpleasant musty smell.
To properly equip the ventilation of the underground space of a frame house, you need to adhere to a number of requirements and practical recommendations of experts:
- Compliance with the size of the cross-sectional area for each ventilation hole in the subfield. Its value can be from 0.04 to 0.06 m ?.
- The total area of all vents should not be less than 0.25% of the total area of the subfloor.
- The distance from the ground to the air blower should take into account the average snow cover in the winter period for your region.
- The location of the products is assumed opposite each other.
- The location of the intake vent should be provided 15 cm below the exhaust air outlet.
- The presence in the subfield of internal partitions provides for an obligatory device of airways in each of them.
- To ensure a minimum inflow during the cold period, it is allowed to insert into the holes of mineral wool.
- From the outside, the holes are provided with nets from small objects and animals getting into them.
- If the floor of the house does not exceed 0.3 m, then air ducts are made in the floor, next to the wall. At the same time it is necessary to ensure that they do not overlap with floor coverings or pieces of furniture.
Helpful advice! If the underground space of your home has insufficient height for a ventilation device, use a special ventilation plinth that has a ventilation slot on the bottom plane.
The methods of ventilation of the subfield space are also divided into natural and forced. With natural ventilation, air exchange is continuous. Such ventilation is not dependent on energy supply. If the frame house is located on the ground relatively high, then the presence of ventilation holes will be enough. If the house is located on a low-lying place, a galvanized or plastic box is mounted to the exhaust holes (usually on the north side). This is done to create appropriate traction. Box sizes are selected taking into account the normal thrust.
Forced venting of a subfield provides for the use of several fans in the system. As in the case of the ventilation system for the frame house itself, and for the ventilation of the subfloor, the artificial ventilation system is envisaged at the design and construction stage.
Do not neglect the device necessary ventilation system frame house. Take care of your health and the health of your loved ones.
