The roofing aerator allows to protect roof from condensate, to prevent damage of rafter system. Devices create draft in pipe, allow to achieve the necessary effect at the expense of the difference of pressure in subroofing space on the street.
One of obligatory elements of the ventilated roofs is the aerator. It is mounted for withdrawal of the water vapor or moisture accumulating in subroofing space. The quantity of similar elements depends on the area, technical features.
The roofing aerator consists of pipe with diameter of 6-11 cm. Is made mainly of stainless steel or polypropylene. Atop the special cap is established. It does not allow penetration in precipitation. The aerator allows to accelerate drying of thermal insulation material, accelerates condensate evaporation process, prolongs roof life cycle.
Devices are suitable for installation in regions with various weather patterns as differ in good operational parameters, maintain essential temperature loads.
The aerator is suitable for the solution of the following tasks:
aerations of layers of roofing pie;
- condensate evaporations;
- removal of humid air;
- prevention of processes of destruction of roof.
Types of roofing aerators
On design of the device happen:
- dot;
- continuous;
The first look has the fungate form, is equipped with the fan. Most often it is established in places with limited access because of difficult configuration or because of availability of windows. Similar options are cattle and ridge. The last intend for elimination of vapors along all design of the fad.
Continuous place on all roof so that there is work with all layers of pie, sites of attics and penthouses. The ventilating moisture-proof tape is most demanded. It is established in waterproofing layer.
Turbine are made in the form of pipe. Such models have electrically driven extract. Differ with production material, but many give preference to aluminum. Such options are resistant to corrosive processes, do not change property under the influence of high temperatures.
Types for different types of roofs
Aerators for professional flooring are more often provided by the cattle option located under certain corner on roof. Characteristics at similar types are similar, differ only in professional leaf wave height.
Devices for metal tile differs in small parameters and simplicity of installation. Such type has the special form allowing to fit ideally into exterior. Thanks to availability to the special rubberized nozzle the dense clip to roof is carried out that reduces the probability of emergence of leakages. To advantages durability, belongs to shortcomings – quite high price.
The aerator for soft roof is similar to the previous option, but has the flat basis. If the roof is made on bituminous basis, then pipes with caps can be applied.
Features of the choice
If it is difficult to decide on suitable option, it is necessary to consider:
- type of roofing covering;
- roof bias;
- number of aerators.
All products make under different roofing materials. It is not recommended to neglect data on marking. In the return case the installation not only will not perform the functions, but also can break integrity of roof.
Also the bias is important. The exception is made by ridge types – for them this parameter is not important. The quantity of products depends on type of material, the roof size. Usually pays off individually.
The basic rules can be considered on popular cattle types. At their mounting the distance from the fad to the place to installation should not be more than 60 cm. At the same time all elements are established with step to 12 m. At big bias of roof and height differences between the fad and surface of roof of the device are established parallel to the fad and the water separating basis.
Pay attention that dot types can be established on flat roofs where the bias is no more than 12 degrees or not opportunities to install the roofing aerator.
Features of installation
All works can be carried out in several steps:
- On surface the opening by the corresponding sizes becomes. Depth has to correspond to heater, pass through all roof.
- For providing reliable and hermetic adjunction of the aerator the sealant or mastic recommended in the instruction is applied. In addition they are applied to processing of rubber ring laying.
- "Skirt" of element through passage joins roof with use of self-tapping screws. The last have to be established in certain sequence on the opposite sides.
- The pipe with fungus is inserted into element through passage.
During the works pay attention to subroofing material. If in the worksite it was damp, it is replaced with dry material.
In conclusion we will note that prices for aerators different. The inexpensive devices consisting of three parts, equipped with special ring. If the aerator consists of 4 parts, has unique cap for creation in pipe of additional draft, then its cost will be twice higher, than in the previous option. Such models are used in areas with considerable to snow covers.
If ventilation over heater and under vapor barrier is necessary, then the special look, consisting of 4 constituent parts is used. The aerators working at difference of pressure caused by air streams are the most expensive. The cap Skonstruiruyemy unusually provides additional draft.
