Each time it comes to the roofs of the frame type, when designing and operating, you have to worry about the diving of moisture from the subcutaneous space. Due to the difference in temperature and humidity between the outer air and the air inside the house, the condensation of the vapor of the lag is inevitable. Take care of the proper rescue of this moisture, the paramount task when designing and repairing the roof, the implementation of which will maintain the strength of the roof for many years.
You can solve this problem yourself if you install a roofing aerator for a roof with your own hands. Some owners of private houses believe that a flat roof does not need, unlike the pitched, in forced aeration, but this is not so. The accumulation of moisture under flat blood can lead to its swelling, and a violation of its properties.
The functions of the aerator are as follows:
All moisture, which rises in the form of water vapor from the lower rooms to the under -wrapping space, is excreted in the outside. The process of abduction occurs continuously, preventing moisture from condenses and moisten wooden elements of the roof and layers of insulation.
Even if the aerator is installed after the construction of the roof and put it into operation, the abduction of water vapor will reduce the internal pressure on the soft roof and prevent its swelling.
The removal of moisture from the underlying space will prevent condensation of water vapor on the lower layers of the available waterproofing, which can be absorbed into the insulation and ruin it.
Structurally, the aerator is a piece of pipe, the diameter of which can be in the range between 63 and 111 millimeters. The top of the pipe segment is closed with a special cap, or an umbrella, the task of which is to protect the aerator from the hit of it from rain or snow. Widely for the manufacture of aerators, polyethylene pipes of suitable diameter are used.
To install the aerator, you need to cut the roofing pie up to the lower layers of the insulation. The condition of the insulation is checked. If the insulation is raw, you will have to replace it with a new and dry. The aerator is firmly attached in the cut window. The lower end of the pipe is lubricated with waterproofing mastic, with self -tapping screws, with self -tapping screws, which are screwed into the skirt specially provided for fasteners. For flat roofs, a standard is adopted, according to which one device is placed for every 100 square meters of roof.
