Aerator for roofing is a device that serves to remove moisture and water vapor from under the roofing . Recently, a flat (soft) roof for buildings and structures has become increasingly popular. However, when installing it, few people think that the insulation, which is one of the layers, accumulates moisture inside itself over time. It is because of it that bubbles appear on the roof, and its thermal insulation characteristics deteriorate. Moreover, the thermal insulation screed is also destroyed. Repairing such damage is quite complicated and expensive. In this regard, it is better to take measures to prevent such situations. Aerators for a flat roof will help here , which remove excess moisture and drain the insulation.
The appearance of the aerator
The device itself looks like a pipe whose diameter is in the range from 63 to 110 millimeters. It is covered from above with a special umbrella, the main purpose of which is to prevent the ingress of rain, snow or other atmospheric precipitation.
Principle of operation
The principle by which the aerator works for the roof is quite simple. Due to the pressure difference inside and outside the roof, a draft is generated in the pipe. Thus, water vapor, which rises up, is led out into the street even before it manages to inflict the slightest harm to the roof structure.
Types of device
There are two types of aerators for roofing - continuous and point. The first of these devices are installed along the entire length of the roof. Due to the fact that they are covered with roofing material, it is almost impossible to notice them to an outsider. In this regard, the exterior of the building or structure does not deteriorate. The point aerator for the roof is made in the form of a mushroom and is equipped with a fan. It is considered one of the elements of the entire ventilation system and is installed on the roof in certain places.
Installation of a roof aerator
Mounting the device is not very complicated. The main thing is to know certain parameters. In particular, it should be borne in mind that a certain distance must be observed between two adjacent "fungi" - not more than twelve meters. In addition, it should be borne in mind that individual devices must be installed for every hundred square meters of the roof. If the building has a high level of humidity (for example, these are saunas, pools), special conditions are established for them by the relevant design organizations.
Installation of an aerator on the roof is carried out in four stages. The first step is a cutout on the roof of the window, the size of which corresponds to the diameter of the pipe. After that, the old wet insulation at the installation site should be measured with a new dry one. The next stage is the application of special mastic to the lower base of the pipe and the fastening of self-tapping screws. Finally, an additional layer of waterproofing is created on the ventilation pipe. When mounting the device on an old roof, it is desirable that the window diameter is 80 or 120 millimeters.
conclusions
In conclusion, it should be noted that the aerator for the roof is a powerful ventilation system, which is the most effective for removing excess moisture from all existing ones. It is easy enough to install it not only on the new, but also on the old roof. At the same time, it is quite durable and does not lose its properties over time.
