Not so long ago, houses were built bya certain principle, the attics in them were cold, and in the space under the roof did not make rooms. This did not imply the need for warming. Under the roof there was a free space through which air masses could climb up from the room. After that, they went out through the roof. To do this, there were always gaps in the eaves, roof, and pediments. Such conditions made it possible to eliminate the accumulation of moisture in the materials. If you are interested in saving, a water aerator will allow you to reduce the costs that go to pay for utilities. But the article deals with other devices. Today, to save energy, roofs have become warm, for the first time this allows us to exclude heat losses. In the attics they furnish the rooms, and because of the rapid pace of private construction, the construction of the system of rafters is installed from a material that is not sufficiently dried. According to developers, it should ripen on the roof. A sewer aerator today can also be found on sale, but it has a slightly different task than the one described in the article. In order to get the warmed roof, the installation of the roofing pie is made, different materials are superimposed on each other. They should be responsible for the safety of heat, as well as the insulation of water and steam. This leads to the fact that all the gaps through which air could escape are closed by a vapor barrier. Moisture accumulates in the hermetic under-roof space and in truss structures. If you are interested in the nozzle aerator, then it should not be confused with the device, which is discussed in the article. Speaking of the above, after a few years, the owners have to fight the fungus, placing buckets in the attic. This is the result of the arrangement of roofs in which there is no good ventilation system with the influx of fresh air.
Description of the aerator
The aerator is the element that is used whencreating a roofing pie. In the process of carrying out these works, three ventilation layers are used, one of which is located in the inner space of the attic, the second is located between the thermal insulation and the waterproofing layer, the third is under the roof covering, but this layer is equipped if necessary. Creating simple air gaps is not enough. It is necessary that the air was walking, moving from the ridge to the eaves. It should not linger in certain places so that condensate does not form. An aerator is an element that is designed to enhance air circulation.
Varieties of aerators
Описываемые элементы способны обеспечивать ventilation in certain parts of the roofing system, so they are called point. The second type is installed along the entire length to ensure ventilation, such components of the roofing system are called continuous.
Description of point aerators
Точечный аэратор - это составляющая кровли, which is necessary for installation on the slopes of the roof. They can be located on the ridge. The first type is installed where it is necessary to increase the movement of air, this can include complex or long slopes, roofing valley and ridges, as well as areas where the ventilation gap can be interrupted. The dormer window or “lantern”, which is sometimes installed on the roof, can act as a barrier. In such areas, the aerator is mounted on both sides of the element that interferes with movement. In order to provide the most efficient ventilation, pitched aerators should be placed correctly, they should be installed 15 centimeters from the ridge. If the construction is not insulated under the ridge, then a pressure chamber will be formed on top. It will receive couples that evaporate from the roof.
Description of ridge models
A ridge aerator is an element thatintended for mansards. In the under-roof space, heat insulation under the ridge can be made. With the help of the described element it is possible to provide a steam outlet through the construction of the skates. The principle of operation here is based on convection, this is explained by the fact that the warm air will rush upward, where it will find a way out. The advantages of this model are that it is capable of bringing harmful substances to the street from bitumen, which is used for arranging soft roofs. Aerators on the roof is very difficult to notice, as they are hidden under the cover.
Continuous aerator for natural tile
Such components of the system most oftenventilation, which is equipped on the basis of natural tile, is complemented. Installation is made along the entire length of the ridge, cornice or ridge. Such a device is popular and is a ventilating ridge belt. With it, you can waterproof the ridge of the diagonal or horizontal type. Because of its elasticity, the tape is able to adapt to the bends of the structure, and the presence of glue base insulates the roof from the penetration of precipitation. Such a tape can provide additional ventilation, since a strip of a breathing membrane passes through the center of the roll. Due to this, couples move freely outwards. For the eaves overhang it is customary to use an aero element that has a ventilation bar. With it, you can provide circulation, among other things, it will act as a seal between the ridge and tile. Such aerators on the roof have barriers that exclude the possibility of penetration into the birds. You can not be afraid that garbage, leaves and other foreign elements will get inside.
Features of the installation of the aerator in the arrangement of the roof
When the master makes laying a new roof onthe surface, which is made of reinforced concrete slabs, then you can resort to installing a plastic aerator, it should be on the bottom layer of material. It is necessary to be guided by a certain technology, which provides for the presence of a hole in the layer of screed and insulation. You should walk to the vapor barrier. The hole formed should have a diameter that varies from 80 to 120 millimeters. Further, expanded clay is poured into the hole, and then a sealant, glue or mastic can be applied to the horizontal surface of the aerator. This will ensure a better grip of the device with the surface of the roof. When the TechnoNIKOL aerator is installed, you should wait for the mastic or sealant to harden, only after that you can fix the fan using 6 screws in the amount of self-tapping screws. They should be screwed around the entire circumference of the pipe skirt. At the next stage, the top layer of the roofing carpet should be fixed, while the aerator should be located in the place where the overlap of the roofing sheet’s carpet will be carried out. The width of the overlap should be 150 millimeters.
Methods of work
The master should remember that in placeinstallation of the aerator coating should be laid as freely as possible. After to the place of pairing of the roofing carpet and the aerator it is necessary to apply a patch from the upper layer of material, so that it covers the device skirt. To enter the coating should be on the surface of the roofing cake at 150 millimeters.
For reference
When installing aerators, you needconsider that the roofing device may assume the presence of only one layer. In this case, the vent element must be installed directly on the screed.
Advice of specialists
If you decide to carry out the current repair of the roof,then a hole needs to be made in the material, the diameter of which can vary from 80 to 120 millimeters. Depending on the number of layers, the hole can reach to the screed or vapor barrier. After that, you can install and fix, if the deflector is installed on the base, which is made of profiled sheet. In this case, you can follow the rules described above. However, it must be remembered that there are some differences. They are expressed in the fact that the hole in the place of installation of the aerator must pass through the top layer of insulation, reaching the bottom layer of insulation. After this, the structure can be installed by fixing it with self-tapping screws to the surface of the profiled sheet. Do not confuse the above devices with those called water aerators - they only suggest saving an appropriate resource in the house.
