Abstract

The windows and doors structures and their performance characteristics prescribed by European directives and determined by the new product standards play an important role in the energy balance of buildings. Between the performance features we find the air tightness of windows, which limit value required by a certain usage must be assured in the moment of installation. This research intends to investigate the influence of structural elements on windows and doors performance. The present article describes the role and effect of sealing’s on windows air tightness. A series of laboratory experiments were performed examining the influence of primary and secondary weather-strips as well as the effect of sealing’s weathering on elasticity. By removing the primary weather-strip the air tightness declined significantly at each pressure level. Opposite to this the secondary weather-strip elimination doesn’t affected considerably the air tightness at certain pressure levels. The impact of primary sealing weathering varied among the examined window types.
