摘要：The climate change creates specific problems in the countries, where it was not so hot during the summer periods in the past. In the area of building envelopes, use of more environmental friendly materials comes to the foreground. Having still more strictly requirements in the thermal protection of buildings, use of lightweight wooden walls is increasing. The ratio between load carrying and insulating parts changed. This is also the advantage of timber framed walls. These walls have also some negatives, or create some problems, such as low thermal capacity. In the Central Europe, the indoor summer overheating started to be a serious problem. In this paper, impact of ventilated cladding on the timber frame wooden wall will be analyzed. One composition, with east and south orientation were evaluated. This wall is a part of the experimental measurement, compared with another ETICS type of outdoor finishing layer. Impact of the ventilated air cavity behind the cladding on the thermal regime of the wall is stated.
