The average air tightness of the ventilation ductwork in France is rather poor, corresponding to a 3A class according to EN 12237. This is mainly due to air leakage in the fittings. Because of difficulties encountered during the implementation as lack of space, access problems or short time to proceed the installation, these fittings are not sealed enough, with mastic or adhesive tape. In order to limit this risk of leakage and to limit sealing operations on site, manufacturers propose components equipped with joints. Some years ago, CETIAT has tested in its laboratories different kind of such components. The results obtained demonstrated the ability of these elements to achieve a good air tightness (class C). In order to determine in real conditions on site whether these results could be maintained, CETIAT has performed some tests on different kind of ductworks in an office building, in a technical school and in a multifamily building. This paper gives and analyses the results.
