For several years, the Timber Research Institute, together with experts from the CTU and ČZU, has been collecting and evaluating data from measurements of the airtightness of buildings. This unique statistical data set was compiled, analysed and published in the prestigious scientific journal Building and Environment, issue 194. The use of the Blower door diagnostic method, which the Timber Research Institute carries out in an accredited mode, has been shown to contribute significantly to improving the performance of timber buildings. Therefore, one of the indirect results of the research is the confirmation of the well-known truth that prevention (using scientific knowledge) is better than subsequent complex and costly repair.
