UnterspannbahnUnderlayment
Die Erfindung betrifft eine flexible Unterspannbahn, die insbesondere für Dächer von Bauwerken geeignet und bestimmt ist.The invention relates to a flexible roofing membrane which is particularly suitable and intended for roofs of buildings.
Dachunterspannbahnen sollen im Dachbereich von Gebäuden gegen Regen, Schnee und Staub schützen. Dabei soll die Unterspannbahn nicht nur ein geringes Flächengewicht aufweisen, sondern wasserdicht, dabei aber dampfdurchlässig und atmungsaktiv sein und eine für die Verar- |A beitung auf Baustellen und auch danach befriedigende Reißfestigkeit aufweisen. Schließlich ist Flammfestigkeit bzw. Flammresistenz gewünscht. Keine der bekannten Dachunterspannbahnen erfüllt alle diese Bedingungen in befriedigender Weise.Roof underlays are intended to protect the roofs of buildings against rain, snow and dust. The underlay should not only have a low surface weight, but also be waterproof, but also vapour-permeable and breathable and have a tear resistance that is satisfactory for processing on building sites and afterwards. Finally, flame resistance is desired. None of the known roof underlays satisfactorily fulfils all of these requirements.
Der Erfindung liegt die Aufgabe zugrunde, eine Unterspannbahn, insbesondere für Dächer von Bauwerken, zu schaffen, welche bei geringem Flächengewicht ausreichende Stabilität aufweist und sowohl atmungsaktiv als auch schwerentflammbar ist.The invention is based on the object of creating an underlayment, in particular for roofs of buildings, which has sufficient stability with a low surface weight and is both breathable and flame-retardant.
Diese Aufgabe wird erfindungsgemäß mit einer Unterspannbahn gelöst, IB welche die Merkmale des Anspruches 1 aufweist. Vorteilhafte Ausge-This object is achieved according to the invention with a roofing membrane, IB which has the features of claim 1. Advantageous embodiments
staltungen und Weiterbildungen der Erfindung sind Gegenstand der &phgr; Unteransprüche.Further developments and refinements of the invention are the subject of the dependent claims.
Die erfindungsgemäße flexible Unterspannbahn hat ein geringes Flächengewicht bei gleichzeitig hoher Reißfestigkeit, die nachThe flexible underlay membrane according to the invention has a low area weight and at the same time high tear resistance, which
DIN 53 857 etwa 400 N/5 cm, d. h. etwa 40 kp beträgt. Sie ist wasserundurchlässig
und somit regendicht ausgebildet, ist jedoch diffusionsoffen mit einem S^-Wert von vorzugsweise kleiner als 0,26, der
besonders bevorzugt etwa 0,25 beträgt.
15DIN 53 857 is about 400 N/5 cm, ie about 40 kp. It is impermeable to water and thus rainproof, but is permeable to vapour diffusion with an S^ value of preferably less than 0.26, which is particularly preferably about 0.25.
15
Eine solche Unterspannbahn ist atmungsaktiv gemäß DIN 53 122.Such an underlayment is breathable according to DIN 53 122.
Außerdem ist die erfindungsgemäße Unterspannbahn derart ausgebildet, daß sie schwerentflammbar gemäß DIN 4102-B1 ist.In addition, the underlay membrane according to the invention is designed in such a way that it is flame-retardant in accordance with DIN 4102-B1.
Die erfindungsgemäße Unterspannbahn bildet einen idealen Schutz gegen Regen, Schnee und Staub, verhindert jedoch Kondensatbildung, da sie atmungsaktiv und somit für Wasserdampf durchlässig ist. Diese Unterspannbahn ist also wasserdicht und zugleich diffusionsoffen.The underlay according to the invention provides ideal protection against rain, snow and dust, but prevents the formation of condensation because it is breathable and thus permeable to water vapor. This underlay is therefore waterproof and at the same time permeable to vapor diffusion.
In der Zeichnung ist eine erfindungsgemäße Unterspannbahn in einem Ausschnitt und teilweise aufgeschnitten in vergrößertem Maßstab schematisch dargestellt.In the drawing, an underlay membrane according to the invention is shown schematically in a detail and partially cut open on an enlarged scale.
Die in der Zeichnung gezeigte flexible Unterspannbahn 1 hat als Festigkeitsträger ein offenmaschiges Gewebe 2 aus einer Anzahl von parallel zueinander verlaufenden Kettfäden 3 und diese kreuzenden und zusammenhaltenden doppelten Schußfäden 4.The flexible roofing membrane 1 shown in the drawing has an open-mesh fabric 2 as a strength carrier made up of a number of warp threads 3 running parallel to one another and double weft threads 4 crossing and holding them together.
Das Gewebe 2 ist, wie die Vorderkante der schematischen Darstellung zeigt, beidseits von jeweils einer flexiblen Folie 5 bzw. 6 beschichtet, die aus atmungsaktivem und wasserdampfdurchlässigem Material besteht, beispielsweise aus Polyethylen. Diese beiden Folien 5 und 6 halten das offenmaschige Gewebe 2 zusammen und sorgen mit diesem Gewebe für die Flexibilität der Unterspannbahn 1.As the front edge of the schematic diagram shows, the fabric 2 is coated on both sides by a flexible film 5 or 6, which consists of breathable and water vapor-permeable material, for example polyethylene. These two films 5 and 6 hold the open-mesh fabric 2 together and, together with this fabric, ensure the flexibility of the underlay membrane 1.
Auf die Außenseite der Folien 5 und 6 ist jeweils ein textiles Vlies
7 bzw. 8 aufkaschiert, das für den äußeren Halt sorgt, jedoch wasser- und dampfdurchlässig ist, um die Atmungsaktivität der Unterspannbahn
1 nicht zu beeinträchtigen.
30A textile fleece 7 or 8 is laminated onto the outside of the films 5 and 6, which provides external support but is permeable to water and vapour so as not to impair the breathability of the underlay membrane 1.
