Description

909837/0696
ORlGlMAL INSPECTED
Die vorliegende Erfindung betrifft ein Unterdeckentuch bzw. Unterdachtuch, das mindestens eine v/asserdichte Folie, vorzugsweise aus armiertem Plastikwerkstoff umfaßt.
Zur Herabsetzung der Baukosten hat man in den letzteren Jahren vielfach Unterdecken aus einer festen dichten und 'wasserdichten armierten Plastikfolie eingesetzt. Dieses Tuch kann direkt auf die Sparren gelegt werden und verhindert das Eindringen von Wasser bei starkem Wind, ,defekten Dachsteinen oder anderen Mängeln des äusseren Dachbelages.
Falls dieser Belag aber aus irgendeinem Grund mit unzulänglicher Entlüftung gelegt wird, kann sich ein Niederschlag an der Unterseite der Plastikmembrane bilden« Dieser Niederschlag kann zu Tropfenbildung führen und sich nachteilig auswirken.
Zweck der Erfindung ist die Vermeidung oder jedenfalls die Minderung der schädlichen Wirkungen eines derartigen Niederschlags.
Erfindungsgemäss wird dies mittels eines Unterdeckentuches der eingangs erwähnten Art erzielt, wobei kennzeichnend ist, dass die Folie eine feuchtigkeitsabsorbierende Schicht aufweist«
Weitere vorteilhafte Merkmale der Erfindung gehen aus den Unteransprüchan und aus der nachstehenden Beschreibung der in der Zeichnung dargestellten Ausführungsbeispiele hervor. In der Zeichnung ist Fig«, 1 ein vergrösserter schematischer Schnitt durch einen Unterdeckcnafoschnitt laut der Erfindung^ während Fig„ 2 eine Abänderung des Unterdeckentuches der Fig« I darstellt«.
In der Zeichnung bedeutet 1 eine wasserdichte Plastikfolie, die rait einem Drahtnetz 2 armiert ist,, Die Folie ist an der einen Seite mit einer feuchtigkeitsabsorbierenden Schicht 3 belegt, die
909837/0B96
vorteilhaft aus Zellstoff in der Form von Fasern oder Fasermatten bestehen kann.
Der Belag absorbiert Feuchtigkeit und gibt diese in der Form von Wasserdampf, nicht aber in der Form von Tropfen ab« Der Belag wirkt auch isolierend und setzt derart die Möglichkeit eines Niederschlages herab.
Die Absorptionsfähigkeit des Belages ist im grossen ganzen
2 direkt proportional mit seiner Stärke bzw. seinem Gewicht je m bei der gleichen Art von Fasern« Wie in Fig. 2 dargestellt, kann die Isolationsfähigkeit erhöht werden, indem man einen isolierenden Werkstoff 4 zwischen der Folie 1 und der Fasermatte 3 vorsieht. Der isolierende Werkstoff kann vorteilhaft Schaumkunststoff sein.
