Definitions

  • the invention relates to a ventilation element for roofs, with one in the ridge, hip or Fan cap to be arranged in the burr area and provided with air passage openings and with at least one adjoining the fan cap at its edge area, resilient sealing element.
  • a ridge, Fan cap to be arranged in the hip or ridge area.
  • the word “fan cap” could lead to the assumption that this is a dimensionally stable, i.e. dimensionally stable Body acts. However, this does not have to be the case.
  • Fan cap also understood such an element that is so resilient can be as it is postulated for the sealing member.
  • Ventilation elements of the type in question from sealing members Use foam.
  • the disadvantage is that with different differences in distance and / or sharp-edged transitions of the foam due to its structure is unable to provide adequate tightness, for example against flying snow and driving rain.
  • Another disadvantage is that the foam is not resistant to aging, i.e. becomes brittle and crumbly over time, so that the functionality is not guaranteed. It also requires foam a strong compression pressure, which makes the laying difficult and often unsatisfactory Results in work and sealing. After all, are accessible Areas exposed to bird feeding.
  • a ventilation element of the type mentioned at the outset is already known from DE-A-42 26 817 known.
  • brush strips are used as sealing elements used, the brush strips each having a variety of elastic, in at least largely flow-tight packing arranged brush threads exhibit.
  • the disadvantage is that the fine brush threads can bend, for example if they hit obstacles such as rough spots, edges, etc., causing the tightness is questioned. It is also in critical areas, for example in corner areas, do not ensure that the brush threads up to these areas reach in. Furthermore, the brush threads tend to stand up or when strong Heating of the roofing material to stand out from it and cooling off no longer to return to the starting position, so that in the so released Areas, especially in high wind pressure, flying snow and driving rain can penetrate.
