It is used for ventilation of foils of all kinds in the areas in which the avoidance of Schwitfcwaosver damage, e.g. with the foil laid on the roof beams is aimed for or ventilation appears sensible for other reasons *

Especially with roof trusses where foil underneath the tiles is, despite the presence of a vapor barrier to the rooms below, it can be seen again and again that there is more or less Condensation water condenses on the underside of the film and runs from there into the framework or drips back into the insulation and opens up Seen long-term, it can cause considerable damage. The Firstöder gable ventilation is often not sufficient. The ventilation tiles I As is well known, only the | within the roofing is ventilated Space between brick and foil * '

By using the foil fan on every ventilation tile | optimal diagonal and horizontal ventilation is achieved; of the entire roof beam space. To avoid intrusion f The foil fan is used a little above the brick opening to prevent rain or drifting snow in the roof space. f

This ventilation element is also useful if | instead of roofing membrane roofing felt or similar. on the entablature i | has been laid.

Well-known fans are duct fans and fan stones that are installed in the Masonry can be mortared, as well as ventilation panels made of plastic or metal that is nailed or screwed onto the area to be ventilated.

Use of the floor fan

The foil fan is placed in the direct area of the ventilation tile / And two cuts are made taking into account one Attachment overhang a corresponding area from the foil or the cardboard, against penetration of driving rain or drifting snow the fan is a little above the direct brick opening used. It can be inserted either from the roof by moving the ventilation tile, or from the roof space, if this is accessible.

The attachment according to protection claim point 2 is done by, that the fan is clamped into the film, namely läi.tl: the cut edge of the film cut-out through the frame groove, with which at the same time the surfaces of the frame ' ey.den are secured against slipping.

With the model according to protection claim item <6, the fan is in the Fastening protrusion of the film cut-out is pressed in and is counteracted by the specially designed fastening parts (nipples) Secured from slipping.

In the protection claims points 7, 8 and 9, two elements are used, namely one element on each side of the film cutout. The connection of the two elements results from the fact that the element with the nipples through the fastening overhang of the Foil cutout is pressed and the element is placed with the perforated edge over the nipple. By rotating (moving) the perforated frame in the direction of the slots adjoining the holes, the nipples get a hold there and thus stop the connection of both elements.
