It is used to remove superfluous moisture from under the roof on the roofs covered with slender tiles without a ridge. The air element creates changes in pressure under the roof leading to moisture evaporating from the warmth-keeping jacket due to the air motion. It is installed 0.5-0.8 m far from the ridge of a roof, and air intake is provided on the overhangs. One aerator ventilates 5 m2 of a roof if the ventilated area under the roof isn't higher than 5 cm. Air Element KTV TechnoNICOL is made of polypropylene of different colors that allows it to fit into a roof of any color harmoniously. It is resistant to losing color.
