What are the ventilation gaps in a frame house with your own hands when insulating a roof or attic: Step-by-step instructions- Review + Video

It is extremely important not to forget about a special ventilation gap during the construction of a frame structure.

Each frame structure must be equipped with it, its depth must be at least 5 cm. Its location is between the OSB3 board (or another name) and the superdiffuse membrane.

Equipping any structure of this type with a professionally calculated and installed ventilation system is of great importance. It's no secret that for a cozy and comfortable stay in a house, it must be equipped with a high-quality ventilation system.

Heating, air conditioning and ventilation in these types of dwellings are usually included in the main project, based on competent calculations. If everything is done according to them, properly, then the system will perfectly cope with heating the house in cold weather, and cooling it in the heat.

Modern technologies used in this type of construction provide structures with maximum tightness. Plus the use of very topical thermal insulation materials. Together, this allows you to keep the maximum amount of heat inside the structure.

But, on the other hand, this turns into a significant drawback: getting fresh air into the house from the outside also becomes very difficult. The processes of human economic activity, and his own life, have a negative impact on the microclimate of the room . Odors appear in it, humidity rises, dust accumulates, the ratio of oxygen in the air decreases.

Precisely because of of all of the above, in a building built using frame technology, an effective ventilation system cannot be neglected. It can be artificial or natural.

Ventilation of the natural type occurs during normal air exchange with the street through the openings of windows and doors, ventilation grilles.

Installation of special supply valves in the wall will significantly enhance such air exchange.

The frame structure must be equipped with special, forced ventilation.

Ventilation ducts should be approximately 6 centimeters higher than the grille installation levels.

This difference will ensure efficient operation of the system. Heat transfer takes place especially well when there is a noticeable difference in temperature inside and outside the room. In winter, the system copes with the tasks assigned to it especially well. But at this time, additional heat loss occurs. After all, the cold air coming from the street must be heated.

The ventilation ducts are located in the very frame of the building. For them, plastic (or asbestos-cement) pipes with a cross section of 100 mm or more are used.

Do you need ventilation in a frame house? Her device

Artificial ventilation is called ventilation, which contributes to a significant forced outflow of air masses. Natural ventilation of a building is extremely simple and cheap to organize, but is too ineffective in the heat . In cold weather, it increases heat loss.

To neutralize the aforementioned shortcomings, you should use additional ventilation of the frame house - forced, with heat recovery.

The essence of this process is that the polluted air, before leaving the house, ends up in a special chamber, where it gives off heat to the air from the street. Mixing of air streams must not occur.

To equip such a system in a building, with your own hands, you will have to go for significant expenses.

But they are quite payable in the process of further operation due to the preservation of heat in the house. Such a device pays for itself in about two years of operation, and then it begins to save the resources of the owners, up to 20 times in total.

Is it possible to determine the correct installation of the ventilation system? What indicators should you pay attention to?

• A musty smell that is constantly present inside the home indicates poor air exchange;
• The appearance of mold in the corners, especially in the bathroom and toilet, means excessive humidity, which is usually caused by insufficient ventilation in the building;
• Often fogging and "crying" windows are also a marker of insufficient heat transfer, as well as high humidity, and in general, poor ventilation.

Frame house and ventilation gap

Reliable, simple ventilation of wooden houses is usually carried out naturally.

A building made of natural material does a good job of maintaining a comfortable temperature in the summer heat, while the furnace heat in the winter cold is quite enough to heat the icy air coming from outside. But you still need to remove stale air from your home. Usually, the necessary ventilation is provided through the frames of doors and windows made of wood.

During the construction process, it is important not to forget about the placement of the ventilation gap.

It is usually placed between the exterior trim and the film insulating membrane.As an insulating fabric, simple nonwovens are often used, as if wrapping the structure from all sides.

Then vertical beams are nailed on top of the film covering it (later, external trim will be attached to them), creating a ventilation gap around the entire perimeter of the structure.

It turns out such a sandwich, or pie: lining, film vapor barrier, thermal insulation material, frame racks, a layer of wind insulation, directly a ventilation gap, exterior trim on a bar. The layers go sequentially, one after another.

This is the correct, tested empirically on many objects, as well as time, installation option.

Types and types of ventilation equipment

• Apartment ventilation or at home can be carried out by the channelless method (by means of a fan built into the window transom), or by arranging duct ventilation (using distribution ducts).
• Various settings for duct ventilation are made by manipulating ventilation grilles, diffusers and duct ends. Lattices and diffusers are equipped with special shutters - curtains, opening and closing of which regulates the intensity of air flows.
• If the supply ventilation involves the installation of air conditioners, the air in the living room will not only be fresh, but also have a specified temperature.

  Often such systems are equipped with special automation that has a programming function to maintain a given microclimate. Such equipment maintains the required temperature in an autonomous mode according to predetermined parameters.

All types of ventilation help prevent the formation of musty air in the room, prevent the occurrence of unpleasant odors, and increase the percentage of oxygen in the air. The ventilation system occupies the same important place in the life support of a residential building as the electricity and water supply systems. Especially in sealed residential areas.
