Abstract

A rollable sheet of thermal insulation consists of a hard foam material with a backing sheet projecting at one or both edges beyond the foam; the material contains vapour escape cavities and the foam is sub-divided by cuts, thus forming sections which are interconnected only by the backing sheet. These foam sections about directly against one another, so that there is no gap between them to reduce the insulating value and they are foamed directly on-to the backing sheet. The backing sheet may be a bitumen sealing sheet, or a roofing sheet material esp. of thermoplastics or elastomer. The front side of the foam, i.e. that remote from the backing sheet, which may possess an irregular surface, is pref. faced with a metal foil to constitute a vapour barrier.

Description

Rollbare Wärmedämmbahn. Rollable thermal insulation sheet.

Die Erfindung bezieht sich auf eine rollbare Wärmedämmbahn, bestehend aus einem strangförmigen Hartschaumformkörper mit einer einseitigen starken, an mindestens einem Seitenrand überstehenden feuchtigkeitsdichten Kaschierung und mit Dampfableitungshohlräumen, der in Abschnitte unterteilt ist, welche nur durch die Kaschierung biegsam zusammenhängen. The invention relates to a rollable thermal insulation sheet, consisting from a strand-shaped rigid foam molding with a one-sided strong, on at least one side edge protruding moisture-proof lamination and with Vapor evacuation cavities, which is divided into sections, which only through the The lamination is connected in a flexible manner.

Solche rollbaren Wärmedämmbahnen sind bereits bekannt. Such rollable thermal insulation sheets are already known.

Sie wurden entweder in der Weise hergestellt, dass die einzelnen Abschnitte vorher bereitgestellt und nebeneinander auf die Kaschierungsbahn aufgeklebt wurden, oder es wurde eine grössere Hartschaumstoffplatte auf die Kaschierungsbahn aufgeklebt und nachträglich durch Einsägen in einzelne Abschnitte unterteilt.They were either made in such a way that the individual sections have been provided beforehand and glued to the liner sheet next to each other, or a larger rigid foam sheet was glued onto the lamination sheet and subsequently divided into individual sections by sawing.

Der Erfindung liegt die Aufgabe zugrunde, eine rollbare Wärmedämmbahn der eingangs genannten Gattung in der Weise zu verbessern, dass sie Wärmeverluste durch einen Spalt vermeidet und zugleich in besonders wirtschaftlicher Weise hergestellt werden kann. The invention is based on the object of a rollable Thermal insulation membrane of the aforementioned type in such a way that they improve heat losses avoided by a gap and at the same time produced in a particularly economical way can be.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass die Abschnitte des Hartschaumkörpers, die mit der Kaschierung durch unmittelbares Aufschäumen fest verbunden sind, spaltlos nebeneinander angeordnet sind. Die Herstellung einer solchen Rollbahn kann insbesondere nach dem Verfahren und mit Hilfe einer Einrichtung zum spanlosen Schneiden von Hartschaumstoffkörpern gemäss dem Patent ...... According to the invention, this object is achieved in that the sections of the rigid foam body, which is fixed to the lamination by direct foaming are connected, are arranged next to one another without a gap. The production of such a Runway can in particular after the method and with the help of a device for non-cutting cutting of rigid foam bodies according to the patent ......

(Anmeldung P 24 08 319.0) erfolgen.(Registration P 24 08 319.0).

Dadurch wird erreicht, dass die Wärmedämmbahn nach dem Verlegen in einer Ebene eine in sich geschlossene Wärmedämmschicht trägt, und es werden zugleich Schaumstoffabfälle, wie sie durch Spanabheben des Zertrennens eines Hartschaumkörpers entstehen, vermieden. This ensures that the thermal insulation membrane after laying in one level carries a self-contained thermal insulation layer, and it will be at the same time Foam waste, as produced by chip removal from severing a rigid foam body arise, avoided.

Die Kaschierung kann von einer Bitumendichtungsbahn gebildet sein, die aus handelsüblicher Dachpappe oder einer Spezialdachfolie, insbesondere einem folienförmigen Kunststoffdachbelagwerkstoff, z.B. einem Thermoplast oder einem Elastomer, gebildet sein. Solche Kaschierungsmaterialien sind an sich bekannt. The lamination can be formed by a bitumen sealing membrane, those made of commercially available roofing felt or a special roofing film, especially one foil-shaped plastic roofing material, e.g. a thermoplastic or an elastomer, be educated. Such lamination materials are known per se.

Nach einem weiteren Vorschlag der Erfindung wird eine solche rollbare Wärmedämmbahn, die mit Unebenheiten auf der der Kaschierung entgegengesetzten Flachseite zur Bildung von Dampfableitungshohlräumen versehen ist, in der Weise ausgebildet, dass die die Unebenheiten aufweisende Flachseite des Hartschaumstoffkörpers eine als Dampfbremse dienende Metallfolienkaschierung trägt. According to a further proposal of the invention, such a rollable Thermal insulation sheet with bumps on the flat side opposite the lamination is provided for the formation of vapor discharge cavities, designed in such a way that that the flat side of the rigid foam body having the unevenness Carries a metal foil lamination serving as a vapor barrier.

Ferner kann zwischen dem Hartschaumstoffkörper und der feuchtigkeitsdichten Kaschierung eine mit Perforationen versehene Trennschicht angeordnet sein, so dass der Hartschaumkörper nur im Bereich der Perforationen unmittelbar an der Kaschierung fest haftet. Dadurch wird erreicht, dass in dem labyrinthartigen Gebiet, wo sich die beispielsweise aus Papier bestehende Trennschicht befindet, zwischen dem Hartschaum und der feuchtigkeitsdichten Kaschierung keine unmittelbare Verbindung, sondern ein Druckausgleichsraum gebildet wird, durch den verdampfende Feuchtigkeit bei Überdruck nach aussen abgeführt werden kann, während die unmittelbare feste Verbindung des Hartschaumstoffs in den Perforationsbereichen mit der feuchtigkeitsdichten Kaschierung einen festen Halt der feuchtigkeitsdichten Kaschierung an dem Hartschaumkörper gewährleistet. Furthermore, between the rigid foam body and the moisture-proof Laminating a separating layer provided with perforations can be arranged so that the rigid foam body only in the area of the perforations directly on the lamination firmly adheres. This achieves that in the maze-like area where the separating layer made of paper, for example, is located between the rigid foam and the moisture-proof lamination is not a direct connection, but rather a pressure equalization space is formed through which moisture evaporates at overpressure can be discharged to the outside, while the immediate fixed connection of the Rigid foam in the perforation areas with the moisture-proof lamination ensures a firm hold of the moisture-proof lining on the rigid foam body.

Besonders vorteilhaft ist es, diese Massnahme mit einer solchen Verteilung der Perforationen durchzuführen, dass die Bereiche beider Seitenränder der Rollbahnen von Perforationen freibleiben. Dadurch wird erreicht, dass beim Nebeneinanderverlegen rollbarer Wärm.edämmbahnen der zur Rede stehenden Art unter Verklebung des jeweils überstehenden Seitenrandes der Kaschierung der einen Rollbahn mit der Kaschierung der benachbarten Rollbahn die Kräfte beim temperaturabhänggen Zusammenziehen der Bahnen sich über die Strecke zwischen jeweils zwei benachbarten Perforationen beider Rollbahnen ausgleichen können. Das gilt insbesondere für mit Kunststoffolien kaschierte Rollbahnen, die eine besonders starke Temperaturabhängigkeit aufweisen und bei starken Temperaturschwankungen zum Reisen neigen würden. It is particularly advantageous to use this measure with such a distribution of perforations to carry out that the areas of both margins the runways remain free of perforations. This ensures that when laying next to each other rollable heat insulation sheets of the type in question with gluing of each protruding side edge of the lamination of the one runway with the lamination of the adjacent runway the forces when the temperature-dependent contraction of the Orbit themselves over the distance between two adjacent perforations of both Can compensate for taxiways. This applies in particular to those laminated with plastic films Runways that have a particularly strong temperature dependency and with strong Temperature fluctuations would tend to travel.

Auch die bereits erwähnten labyrinthartigen Druckausgleichsräume zwischen den Perforationen einer Bahn dienen in entsprechender Weise dem Ausgleich temperaturabhängiger Spannungen in deren Folienbahn.Also the already mentioned labyrinth-like pressure equalization spaces between the perforations of a web are used in a corresponding way to compensate for temperature-dependent effects Tensions in their film web.
