Description
Die Erfindung bezieht sich auf eine Dachdämmplatte aus Schaumkunststoff, die zumindest oberseitig mit einer durchgehenden, biegsamen Deckschicht versehenThe invention relates to a roof insulation panel made of foam plastic, which at least on the top with provided with a continuous, flexible top layer
Bei bekannten Dachdämmplatten dieser Art besteht die biegsame Deckschicht aus einer durchgehenden Kunststoffolie, die eine völlige Porendichtigkeit der mit dieser Folie bedeckten Plattenoberseite bewirkt (DT-Gbm 16 93 440). Es hat sich nun gezeigt, daß derartige Dachdämmplatten sich bei einseitiger Wärmeeinwirkung, insbesondere bei Sonneneinstrahlung, auf dem Dach verwölben. In der Fachsprache wird diese Erscheinung als »schlüsseln« bezeichnet.In known roof insulation panels of this type, the flexible cover layer consists of a continuous one Plastic film which ensures that the top of the panel covered with this film is completely impervious to pores (DT-Gbm 16 93 440). It has now been shown that such roof insulation panels are unilaterally exposed to heat, especially when exposed to sunlight, bulge on the roof. In the technical language this is Appearance referred to as "key".
Ausgehend von der Erkenntnis, daß diese Verwölbune der Dämmplatten im wesentlichen durch die obeneitige Deckschicht verursacht wird, liegt der vorlegenden Erfindung die Aufgabe zugrunde, eine derartige Dachdlmmplatte so auszubilden, daß sie sich im «rlegien Zustand unter Wärmec.nw.rkung nichtBased on the knowledge that this warping of the insulation panels essentially by the top layer is caused, lies the present invention has the object of providing a to train such Dachdlmmplatte so that they not in the legal state under heat conditions
"Se «stellte Aufgabe wird bei einer Dachdämmplatte der vorstehend angegebenen Art erf.ndungsgemaß dadurch gelöst, daß die Deckschicht aus Kreppap.er"Se" is the task for a roof insulation panel of the type indicated above according to the invention achieved in that the cover layer made of crepe paper
beSDieherfindungsgemäß aus gekrepptem Papier hergestellte Deckschicht verhindert e.nwandfrei ein Verwolben der Dachdämmplatte, insbesondere bei Sonneneinstrahlung. Während glatte Deckschichten unter Wärme- BES The cover layer according to the invention made from creped paper h prevented e.nwandfrei a Verwolben the roof insulating board, especially when exposed to sunlight. While smooth top layers under heat
„ e nwirkung leicht schrumpfen, wodurch em Verwolben der Plaüe bewirkt wird, kann bei einem gekreppten Papier der Schrumpfvorgang auf die Wellen übertragen Sen, die sich dann verformen, ohne daß eine SDannune in der Deckschicht auftritt.The effect will shrink slightly, causing warping the plaüe is effected, can with a creped Paper the shrinking process is transferred to the shafts Sen, which then deform without the occurrence of a slack in the top layer.
