Aerators for soft roofs. Roofing aerators technonikol Ridge aerator for bituminous tiles

When building a roof, it is important to ensure that all structures are protected from moisture. materials such as wood or mineral wool hygroscopic. The first, when saturated with moisture, begins to rot and lose its strength characteristics. The second, accumulating water, increases the mass, puts a lot of pressure on the roofing cake and ceases to perform its functions. To protect against precipitation and moisture from the room, vapor barrier and waterproofing are used, but as additional measure it is necessary to provide a ventilation gap between the sheets shingles and heat insulating material. In addition, air outlets are required, which are provided in the ridge and eaves. A ridge mounted aerator for a soft roof will ensure the movement of air masses.

The principle of operation of the aerator

Soft roof ventilation is a responsible process. The ridge is equipped with special aerators, and on the eaves, air passes through special holes, which are created in two ways:

• installation of special perforated soffits that do not prevent the ventilation gap from constantly changing the air inside;
• installation wooden planks with a run, which provides a passage for air masses.

It will be cheaper to install ordinary boards, but more modern solution will complete the installation of tiles with perforated soffits.

The skate is equipped with aerators, and on the eaves the air passes through special holes

Ridge element, which complements the ventilated gap for soft tiles, provides the passage and exit of air according to the principle of creating traction in the tubes. Installation is carried out in such a way that the system works due to the pressure difference in the space, which limits the roofing cake and in the outside air. The ventilated gap and its accessories are necessary to remove moisture from the surface of the heat-insulating material.

pass fresh air and the exit of the moistened allows to provide the following effects on the roofing cake:

• removal of condensate;
• prevention of wetting of thermal insulation, preservation of its characteristics;
• elimination of the harmful effects of moisture on wooden structures, which hold the roofing cake, therefore, the reliability and durability of structures increases;
• the frequency of repairs of tiles and truss systems is reduced.

In the general case, the ventilation aerator is a pipe that is installed in the ridge. Installation is most often carried out using sections of 63-110 mm. To protect the ventilation outlet from clogging and flooding with precipitation, a special umbrella must be installed on the ridge of the tile. Installation of the umbrella is carried out using a special piece of soft bituminous tiles.

Types of aerators

The ventilation gap is equipped with aerators various kinds. The number of products per roofing ridge is determined from the following conditions:

• the area of ​​​​the slope, which determines how much air needs to be provided;
• technical characteristics of a particular product, which determine the volume of air that products can provide normal passage.

In private construction, the number of elements can be assigned in the process of performing work. For particularly complex objects, the calculation of aerators, which will ensure the unimpeded exit of air masses beyond the roofing pie, is carried out at the design stage in order to avoid violations and troubles during operation.

The ridge aerator, which complements the ventilated gap between the surface of the tiles and the insulation, can be of two types:

• continuous;
• point.

The first provide the passage and exit of air in the space under the entire roofing. Installation of spot elements is carried out if it is necessary to ventilate individual sections of the roofing. They, in turn, are divided into two groups:

• pitched;
• with installation on a skate.

Pitched aerators are designed to further enhance the air flow in the construction of the roof pie. The exit of air masses must be made faster in the following cases:

• complex roof configurations, a large number of fractures and bends that impede the passage and exit of moisture from the space along the coating on the ridge;
• long slopes in which thrust naturally decreases;
• in places where the ventilated gap is interrupted, this may be required depending on the roof structure;
• also prevent the movement of air directed to the ridge, elements natural light such as skylights, dormers and skylights.

Among other things, ridge aerators allow you to bring out the harmful fumes of the main roofing material - bitumen.

Installation technology

To mount the aerator on the ridge and ensure the unhindered passage of air masses through the roof and their exit to the outside, the actions are performed in the following order:

• a window cut in the roofing cake at the location of the product to the surface of the insulation;
• the base of the pipe is treated with special mastic;
• to attach the product to the roof screed, you will need special devices which are called "skirts";
• The “skirt” is put on the elements and fixed on the roof with self-tapping screws; for high-quality fixing, you will need to use 6 fasteners evenly distributed around the circumference additional element for aerator;
• ventilation pipe is necessary in without fail to protect against moisture penetration, for this, laying of waterproofing material is provided.

It is important to remember that any places on the roof where the integrity of the coating is broken are dangerous in terms of leakage. After all work on the installation of ventilation products is completed, the integrity and tightness of the waterproofing in the difficult places. this will provide the roof with the most reliable protection.

Competent performance of all work on the roof will allow you to get reliable protection of all structures of the house from negative influences environment especially such as rain, snow and cold.

Modern roof structures are complex system in which the elements work effectively only by closely interacting and complementing each other. When creating a roofing project from soft tiles, you need to take into account a lot: protect the insulation from getting wet, prevent rotting of the rafter frame and premature wear of the coating. "Warm" roofs, devoid of an insulating air layer, deserve special attention. In order for the microclimate in such houses to be suitable for life, it is necessary to establish air circulation between the under-roof space and the atmosphere. For this on pitched roofs ah, a ventilated ridge is installed, the installation of which is a prerequisite for the organization of forced.

Ventilated ridge - a device installed on pitched roofs for organizing forced ventilation roofs. It is a simple plastic device installed along the ridge of a roof made of soft tiles, corrugated board or metal tiles. ventilated ridge profile has the following features:

1. Reliably seals the ridge connection of pitched roofs so that no leakage occurs through it. The triangular shape of the ridge makes it difficult to seal this weak spot roofs made of corrugated board and corrugated board, through which melt and rain water can seep.
2. Opens air access. The ventilation gap that is formed when installing a ridge of this design opens the way for the heated air inside the room to the street, which creates a kind of draft and forces the air to circulate inside the house.
3. Closes the ventilation gap from the penetration of insects and snow. The device of the ridge is conceived in such a way that water, snow or insects cannot flow into it.
4. Lets evaporate excess moisture. Vapors saturated with moisture are a product of human activity. Together with the air, they rise up, cool and condense on the elements of the truss frame. The thermal insulation layer of a roof made of corrugated board, soft tiles or metal tiles, due to wetting, loses most of its heat-saving properties, and the wood of the frame rots and becomes moldy. Mounting a ventilated ridge solves this problem by opening the air to oxygen and allowing excess vaga to evaporate.

Note! Mounting the skate with ventilation holes is part of the arrangement of a forced ventilation system for a roof made of soft tiles, corrugated board or metal tiles. In order for ventilation to work, vents are installed in the cornices, places where fresh air is taken from the atmosphere.

Installation of a ventilated ridge does not spoil the appearance of the roof, while quality installation this element of the ventilation system cannot be seen. To make the installation site look more aesthetic, a strip of soft tiles or metallic profile which protects the aerator from impact sun rays and penetration of atmospheric moisture.

Operating principle

In the old days, builders did not even think about installing a ventilated ridge, since air naturally circulated through cracks or gaps in building materials and structures. or corrugated board requires almost complete tightness, installation is carried out in the form of a kind of "pie", in which there is a layer of insulation, waterproofing and vapor barrier. This design does not leave a single slit to the air, which is why a stuffy, humid microclimate is established inside the house. To solve this problem, it is necessary at the project approval stage to develop high-quality ventilation. Depending on the type of roof, there are 2 options for ventilation systems:

• Natural. Natural type ventilation is equipped for houses with "cold" roofs, in which the attic is not heated. With this design, dormer windows are made in the roof slope, which are necessary for air circulation. In this case unheated attic performs the functions of an "air cushion" that isolates heated rooms from cold roof. Mounting a ridge with ventilation holes is extremely rare under such circumstances.
• Forced. Forced ventilation works on the principle of convection, which means that heated air always rises. Roofs with a heated attic made of metal tiles, corrugated board and roll materials equip with a ridge aerator, as well as eaves, to force air masses circulate between the room and the atmosphere. The air flow enters roof structure through the air, heats up and rises to the ceiling, exiting through a ventilated ridge and making room for fresh air.

Important! Forced ventilation was developed on the basis of physical properties gas. For its operation, no power sources are needed, since thrust is created according to the law of convection: warm air goes up and cold goes down. To achieve maximum efficiency of the ventilation system, its elements are placed evenly over the entire roof area from corrugated board, metal tiles or rolled materials.

Types of aerators

The design of the ventilation system depends on the area of ​​​​the slopes, the nature of the use of the under-roof space and the roofing material used. Installation of ventilation for "warm" mansard roofs more difficult and more expensive than for cold ones. To determine optimal composition and mutual arrangement elements, perform installation based on determining the volume of air in the attic. The following types of aerators are used for ventilated ridge equipment:

Note! The simplest and inexpensive way ventilated ridge equipment - the use of corrugated ventilation tape. It is sold in rolls, and on the underside of the tape is a self-adhesive layer with a protective film. To install, you need to remove protective film, glue the tape on both sides of the ridge, and then install the metal ridge bar.

Functions

To the unprofessional roofer, ridge ventilation may seem like an unnecessary overhead and an additional cost, but experienced roofers know that this simple measure increases the life of the truss frame and roof covering. Properly designed and installed ventilation system performs the following tasks:

1. Optimizes the microclimate in living quarters. Thanks to the constant flow of air saturated with oxygen, the house is always fresh, not stuffy, and a comfortable temperature regime is maintained.
2. Extends the life of the roofing. The ventilated ridge profile prevents bitumen-based roll materials from swelling due to solar radiation, allows excess moisture to evaporate, which has a positive effect on the service life of roofs made of metal tiles and corrugated board.
3. Maintains a healthy state of the rafter frame and battens. Thanks to the aerator, excess moisture evaporates, and the wood of the roof frame does not suffer from rot, mold and fungus.
4. Does not allow the insulation to get wet. Due to the constant air circulation, the insulation is ventilated and remains dry, which maintains the thermal insulation qualities of the material at a high level.
5. Makes the use of bitumen-based materials safer. Air circulation through aerators eliminates the possibility of penetration of bituminous vapors, which are considered harmful to human health, inside the premises.

Note! Dormer windows established during the organization natural ventilation, are located half the height of the slope, due to which stagnant zones are formed under the very ridge, where the air does not circulate at all. When installing forced ventilation, this problem does not arise, since the aerators are installed directly on the ridge connection, which is the highest point of the roof.

Video instruction

As you know, the TekhnoNIKOL ridge aerator is used as an element that serves to remove excess under-roof moisture. He possesses special protection, a filter based on polyurethane foam, which is designed to exclude the penetration of atmospheric precipitation and insects.

Feature overview

Consumer reviews

The TechnoNIKOL ridge aerator, according to users, is one of the important elements properly equipped roof. Its use provides effective ventilation of the entire under-roof space. According to buyers, after installation, the materials of the roofing system located inside will be protected from getting wet, their thermal insulation qualities will remain at their best. Users emphasize that the aerator significantly extends the life of the entire roof and building. You can be sure that the aerator has high quality, as it has a certificate of conformity.

The need for an aerator

Previously, the TekhnoNIKOL ridge aerator was not used, but subsequently, when arranging roof systems different materials began to stack on top of each other. Such a “pie” is responsible today for the preservation of heat, the isolation of water and steam. All the cracks in the end, through which air could penetrate, are closed with a vapor barrier. At the same time, moisture accumulates in a sealed under-roof space, remaining in roof structure. At the same time, water does not dry out and is supplemented by moisture that comes from outside. In a couple of years, you will be able to observe the fungus that spreads throughout the attic.

The TekhnoNIKOL ridge aerator has become today an important part Modern roofs require the presence of three ventilation layers. The first is located in inner space attic, the other is between the hydro and thermal insulation, while the third is under the roof space. Creating conventional air gaps will not be enough. It is important that air moves from the ridge to the eaves. At the same time, it should not be delayed so that there is no risk of condensation. To enhance air circulation and to create inlets and outlets for moisture, aerators were invented. The air element has a ventilation bar, so birds cannot get inside, and air penetrates and circulates freely. The aerator provides ventilation for separate sections and also guarantees general ventilation.

Mounting technology: tool preparation

Before installing the TechnoNIKOL ridge aerator for soft roofs, you need to read the instructions in more detail, because failure to follow them may cause the element to malfunction. First you need to prepare the tools, among them:

• a circular saw;
• cord for marking;
• a hammer;
• scissors;
• gun for ;
• roulette;
• mastic in a cartridge.

Work methodology

It is carried out on which varies from 14 to 45 °. Installation should be carried out exclusively on. A prerequisite for this is the presence of vents that provide fresh air from the eaves. When the ridge aerator for the TechnoNIKOL soft roof is installed, the nails must enter the base by 6.3 mm or more. The slots should be away from the edge outer wall 300 mm or more. At the end or beginning of the ridge, the aerators should protrude 250 mm above the roof. In order to avoid deterioration appearance roof and building structures, aerators should be installed along the entire length of the ridge.

It must be remembered that the continuous ridge aerator "TekhnoNIKOL" has closable and closing endings, they are connected when applied and form an airtight and solid construction. Installation must begin from the edge of the ridge of the closing end. As final stage the end is covered by the factory end. Structural ribs should be placed on the flat top of the last row of shingles, otherwise leakage may occur. For this installation ridge aerator"TechnoNIKOL" may be accompanied by trimming the material and moving the elements towards the partitions.

In order to replace the roof, the first step is to get rid of the old ridge tiles. If the roof is new, then you need to immediately cut the base with circular saw. If you have to work with a roof that has a ridge beam, you need to determine the point where the vent will be located. It is important to provide a gap in each direction, the width of which is 13 mm. If you have a roof without a ridge beam in front of you, then 13 mm must be retreated in each direction from the ridge.

The next step is cutting along the marked line. All slots must be 300 mm from the edge of the outer wall or chimney. When the TechnoNIKOL ridge aerator is being installed, two ridge shingles must be fixed along the edges of the roof. The aerator must be bent to give it the desired shape and facilitate installation. Covered and covering ends should be aligned when applied, and no additional sealing is required.

Conclusion

The TekhnoNIKOL ridge aerator, the dimensions of which were mentioned above, must be reinforced with nails with a covering end. Nails are installed in special holes. The baffles of the aerator should be placed on the flat part of the last row of covering material, otherwise you may run into leaks.

The device of roof ventilation allows to avoid accumulation of moisture in the under-roof space and leaks, to ensure effective ventilation of all premises of the building. The house creates a microclimate, which reduces the cost of heating and air conditioning. Roof aerator TechnoNIKOL must be purchased for correct operation roofs.

When laying a soft roof, it is imperative to provide a ventilation system. One of its elements is an aerator. It can be of different variations, designed to eliminate moisture that accumulates on the insulation and screeds. They can be installed on roofs of any configuration and with different slopes. By installing these additional elements, the movement of air flows under the roof is improved, this protects wooden floors from rot and mold and overheating attic space during the summer period.

Description and types

Soft roof in summer time can heat up to 100 degrees, while the heated air is converted into steam, which is collected on inner surface roof and then settles on its solid wooden crate, and accumulates on the insulation.

If it gets wet constantly, it will not be able to fulfill its purpose and lose its thermal insulation properties. After it dries, it will not fully restore its performance characteristics therefore, a reliable ventilation system is required.

Before buying its element - an aerator, you need to understand design features its types, and there are two of them:

Without the use of aerators, the service life of a soft roof will be reduced. Such devices:

• Prevent rotting of the wooden truss structure and malicious activity different microorganisms.
• Do not allow the roof to overheat in the summer.
• Protect soft roofing from cracks, blisters, breaks and deformations.
• They remove bituminous vapors that accumulate, forming due to high temperatures.
• Eliminate stale air and let in fresh air from outside.
• Eliminate the settling of condensate, which spoils the thermal insulating layer. Damp insulation increases the humidity in the attic or attic.

Advantages of aerators:

• They can be installed on both new and old roofs.
• Among numerous colors you can easily choose the right shade for the color of the soft roof.
• They have an interesting design.
• They have a simple, but at the same time hermetic design.
• Not subject to fading from ultraviolet radiation.
• Such elements work perfectly in any climatic conditions.
• They do not respond to corrosion.
