Verfahren zur Herstellung einer Wasserdampfsperre auf flachenMethod of making a water vapor barrier on flat

WarmdächernWarm roofs

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung einer Wasserdampfsperre auf flachen Warmdächern.The present invention relates to a method for producing a water vapor barrier on flat warm roofs.

Besonders bei lose verlegten Dachdeckungen für flache Wanndächer unter Verwendung von Baustoffen aus Kunststoff mussten die Dampfsperrbahnen, z.B. aus Weich-PVC, gegenüber rauhen Unterlagen, z.B. den nicht geglätteten Betonflächen der Tragkonstruktion, durch eine zusätzliche Lage geschützt v/erden. Es mussten somit zwei voneinander getrennte Arbeitsgänge durchgeführt werden.Especially in the case of loosely laid roofing for flat wall roofs using plastic building materials, the vapor barrier membranes, e.g. made of soft PVC, against rough surfaces, e.g. the non-smoothed concrete surfaces of the supporting structure, protected by an additional layer. This meant that two separate work steps had to be carried out.

Es bestand daher die Aufgabe, dieses Verfahren zu verbessern.The object was therefore to improve this process.

Die vorliegende Erfindung löst diese Aufgabe indem sie aus einen Verfahren zur Herstellung einer Wasserdampfsperre auf flachen Warmdächern besteht, welches dadurch gekennzeichnet ist, da3 man eine 5 bis 15 mm starke Schicht aus teilweise vernetzten! Polyäthylenschaum mit einem spezifischen Gewicht von 30 bis 1C0 mg unmittelbar auf der Fläche der Tragkonstruktion lose verlegt»The present invention solves this problem in that it consists of a There is a method for producing a water vapor barrier on flat warm roofs, which is characterized in that one a 5 to 15 mm thick layer of partially cross-linked! Polyethylene foam Loosely laid directly on the surface of the supporting structure with a specific weight of 30 to 1C0 mg »
