Abstract
Description
Die Erfindung bezieht sich auf eine Dachdämmplatte aus Schaumkunststoff, die zumindest oberseitig mit einer durchgehenden, biegsamen Deckschicht versehen istThe 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 is
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« bezeichnetIn 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"
bung der Dämmplatten im wesentlichen durch die oberseitige Deckschicht verursacht wird, liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine derartige Dachdämmplatte so auszubilden, daß sie sichThis is because the insulation panels are essentially caused by the top layer The present invention has the object of designing such a roof insulation panel so that it is
S im verlegten Zustand unter Wärmeeinwirkung nicht verwölbtS not warped when installed under the influence of heat
Die gestellte Aufgabe wird bei einer Dachdämmplatte der vorstehend angegebenen Art erfindungsgemäß dadurch gelöst daß die Deckschicht aus KreppapierThe object is set according to the invention for a roof insulation panel of the type specified above solved in that the top layer of crepe paper
ίο bestehtίο exists
Die erfindungsgemäß aus gekrepptem Papier hergestellte Deckschicht verhindert einwandfrei ein Verwölben der Dachdämmplatte, insbesondere bei Sonneneinstrahlung. Während glatte Deckschichten unter Wärme-The cover layer produced according to the invention from creped paper perfectly prevents warping the roof insulation board, especially when exposed to sunlight. While smooth top layers under heat
einwirkung leicht schrumpfen, wodurch ein Verwölben der Platte bewirkt wird, kann bei einem gekreppten Papier der Schrumpf vorgang auf die Wellen übertragen werden, die sich dann verformen, ohne daß eine Spannung in der Deckschicht auftrittshrink slightly, causing warping the plate is caused, the shrinking process can be transferred to the waves in a creped paper which then deform without stress occurring in the top layer
Als Ausfühnmgsbeispiel der Erfindung ist in der Zeichnung eine Dachdämmplatte in perspektivischer Darstellung gezeigtAs Ausfühnmgsbeispiel the invention is in the Drawing a roof insulation panel shown in perspective
Die Dachdämmplatte besteht aus einer Schaumkunststoffschicht 1, welche eine aus Kreppapier bestehende Deckschicht 2 aufweist Die aus dem gekreppten Papier gebildete Deckschicht 2 ist mit Bitumen getränkt Die Schaumkt-nststoffschicht besteht aus einem Polyurethanhartschaum. The roof insulation board consists of a layer of foam plastic 1, which has a cover layer 2 made of crepe paper. The one made from the creped paper The top layer 2 formed is impregnated with bitumen. The foam plastic layer consists of a rigid polyurethane foam.
