Test results for the durability of connections of airtightness layers by means of adhesives and tapes

So that a building meets its requirements regarding stability, energy conservation and hygiene, it is not only necessary, that the airtightness layer is really airtight in its plenary formation, but also that functionality is given within the range of plate or track joints as well as with connections and completions. With the available contribution new realizations are to be represented regarding the durability of adhesives and tapes to different adjacent construction units and with course transitions of airtightness layers. Since the suitability of these connections should extend on the life span of a construction unit, in addition the adhesive strength of the connecting devices with consideration to different methods of the artificial aging of the used materials was examined. In addition the results of a newly-developed testing method are presented, which is to be geared to reality. The available investigations were accomplished at the scientific institute for thermic protection (Forschungsinstitut fr Wrmeschutz, FIW) in Munich.
