Definitions
- the invention relates to a multi-pane insulating glass with a rim, e.g. as edge protection, according to the preamble of claim 1, in particular a fire protection glass with at least one toughened pane or a pane made of glass ceramic.
- Multi-pane insulating glass consists of at least two glass panes, which are kept at a distance by a web inserted between the edges.
- the web or spacer is usually formed by a generally metal profile, in which there is a desiccant, which is connected via openings to the space between the panes.
- the web or spacer is offset somewhat inwards, so that a sealing compound can be introduced into the edge region between the panes, which causes the panes to hold together and at the same time seals the intermediate space from the atmosphere.
- a seal usually made of butyl rubber / polyisobutene, is also used between the spacer and glass as a water vapor diffusion barrier (e.g. DE-PS 36 37 064).
- edge protection are plastic profiles, through which the edge of the glazing is bordered, for example described in DE-PS 24 54 530, DE-PS 32 29 421 or DE-OS 36 19 780.
- pressure compensation systems such as those described, for example, in DE-OS 36 37 064 are often used. These pressure compensation systems consist of a valve that opens in the event of a fire and thereby releases the increased gas pressure that builds up inside the insulating glazing due to the temperature increase before it causes the panes to burst.
- profile strips can only be used as edge protection if they are provided with holes that correspond to the openings in the pressure compensation systems, which is complex in terms of production technology.
- EP 202 555 A to use, as edge protection, a flexible band made of a gas-impermeable material which is provided with holes at the points for the pressure equalization openings.
- the object of the invention is to find a multi-pane insulating glass with an inexpensive edge protection suitable as edge protection, with which, with the same size, panes of different thicknesses can also be bordered when using sealing compounds which absorb moisture from the air and below Dispensing of volatile reaction products can be crosslinked, can be applied immediately after the pane assembly, which does not cause long-term damage and can also be used without problems in glazing with pressure compensation systems.
- the edge surround serving as edge protection for the multi-pane insulating glass according to the invention, in its raw state, consists of a flat, flexible band that is only through the application to the edge of the glass takes on its final shape.
- the band also consists of a gas-permeable material.
- These multi-pane insulating glasses are in particular fire-resistant insulating glasses with at least one toughened pane or a pane made of glass ceramic, in which silicone-based sealing compounds are used for reasons of fire protection.
- the reaction products released during the crosslinking of the sealant in the case of the above-mentioned fire-resistant insulating glass in general acetic acid, can also be removed to the outside through the edge protection tape.
- the tape can be attached to the disc in such a way that the glass edges and the edge of the disc are glued, e.g. the sealing compound itself, are coated, whereupon the tape is pressed; however, it is preferred if the tape (on one side) is provided with a self-adhesive layer. If the entire width of the tape is self-adhesive, make sure that either the adhesive is gas-permeable e.g. is porous or that the adhesive is only sporadic, e.g. is applied in a dot or strip pattern, so that there is sufficient uncoated tape surface between the adhesive islands, which allows gas to pass through.
- the adhesive is gas-permeable e.g. is porous or that the adhesive is only sporadic, e.g. is applied in a dot or strip pattern, so that there is sufficient uncoated tape surface between the adhesive islands, which allows gas to pass through.
- Another advantageous embodiment consists in that at the point opposite the sealing compound, i.e. usually in the middle of the tape to provide an adhesive-free zone.
- This adhesive-free zone can be wider or narrower than the space between the panes filled with sealant. With a narrower zone, it only has to be ensured that the passage of gas is still possible to a sufficient extent.
- Textile substrates in particular woven or felt tapes, but also tapes made of nonwoven are suitable as the material for the tape.
- the textile substrates can consist of organic fibers or threads made of cotton, viscose, wool or plastic, for example polyester, etc., and particularly fire-resistant fibers, for example of post-chlorinated PVC, can also be used.
- Textile substrates made of inorganic fibers, for example glass fibers, are also particularly suitable because they are inexpensive and non-combustible.
- gas-permeable films or paper strips can also be used, which can also advantageously be equipped with self-adhesive.
- the foils or the paper can additionally be provided with perforations, which enable an improved gas exchange.
- the size of the perforations should be such that no or as little as possible uncured sealant can penetrate. Microperforations in which the openings are so small that water vapor but no water drops can pass through are particularly advantageous.
- Paper as well as the film material can also be reinforced with reinforcing fibers, e.g. Glass or plastic fibers can be offset.
- tapes made of open-pore foam rubber or foam plastic strips or tapes made of porous foils are also possible.
- the foam strips and the foils must be free of plasticizers, since it has been shown that the plasticizers usually used have a long-term effect on the adhesion between the pane and the silicone sealant. In the case of sealing compounds which are insensitive to plasticizers, this requirement need not be observed; however, the tapes can then no longer be used universally.
- the strips can also be metallized, which can sometimes offer optical and technical advantages.
- the thickness of the strips should be such that the strips on the one hand provide adequate protection for the edge of the pane, but on the other hand they are still flexible enough to be easily placed around the edges or the edge of the pane.
- thicknesses of 0.05 to 15 mm are possible for the tape.
- the tape thicknesses are between 0.1 and 1.0 mm, when using textile tapes made from inorganic fibers about 0.1 to 0.8 mm;
- Foils and paper are generally used with a thickness of 0.05 to 0.8 mm and foam foils should, depending on the mechanical hardness of the foam, be between about 0.2 and 15 mm thick.
- the width of the strips should be so large that the strips or edges of the disks are secure, ie without risk of detachment of the tape from the edge of the disc. However, the width should not be so large that the tape looks out of the frame rebate after the pane has been installed in the window frame. In general, the tape should encompass the edge of the disk by about 15 mm each.
- the band can also be arranged asymmetrically if this is considered desirable.
- a band width can be used with different panes with different thicknesses, because if the pane thickness is varied by, for example, 5 mm, the overhang of the band on the pane surfaces changes by only 2.5 mm.
- the double-pane insulating glass shown in FIG. 1 consists of the two glass panes 1 and 2, which are held at the desired distance from one another by a hollow profile 3 serving as a spacer.
- a drying agent 4 in the form of granules.
- the gas exchange between the drying agent 4 and the space 6 between the panes 1 and 2 takes place via perforations 5.
- the hollow profile 3 is set back somewhat from the edge of the pane, around a joint for receiving the sealing compound 7, by means of which the panes 1 and 2 are glued together and sealed off from the outside.
- sealing compound 7 a silicone sealing compound reacting with the air moisture and thereby crosslinking is preferably used, in which the reaction with the air humidity proceeds with the release of acetic acid.
- the edge enclosure 9 serving as edge protection consists of a cotton fabric tape which is provided with a gas-permeable adhesive layer and is glued around the edges of the panes 1 and 2 and via the sealing compound 7.
- the adhesive layer is not shown separately. All conceivable adhesives are suitable as an adhesive for the edge enclosure 9, as long as they enable a sufficiently firm connection of the edge enclosure 9 with the glass panes and, upon contact with the sealing compound 7, do not cause any harmful reactions which impair the pane assembly.
- the edge surround 9 is drawn around the edges to different degrees and extends further over the edge of the pane on the right side than on the left side.
- FIGS. 2 and 3 show sections of tapes which are suitable as peripheral edging before being attached to the pane, to be precise seen on the adhesive side.
- the tape according to Figure 2 consists of a fabric tape; the self-adhesive coating is applied in strips 10 which run obliquely to the direction of tape travel. The areas of the tape which are free of adhesive and lie between the adhesive strips 10 allow sufficient gas passage so that the crosslinking of the sealant and the removal of the reaction products formed during the crosslinking is ensured.
- FIG. 3 shows a tape which consists of a gas-permeable film and is completely provided on one side with a self-adhesive coating. The gas exchange between the sealant and the atmosphere is improved here via the perforations 11 which are arranged in the center of the band and which run in the region of the sealant when the band is attached to the disk.
- the adhesive layer is not shown separately here.
- edge surround suitable as edge protection is inexpensive to manufacture, that the band used as the edge surround can be stored in roll form before being applied to the edges, that a bandwidth can be used for glazing of different thicknesses, which the Warehousing is simplified and, above all, that the edge surround can be used immediately after the production of the composite pane even with sealing materials that require gas exchange with the atmosphere for a long time to crosslink, as well as for glazing with pressure compensation systems.

Abstract
Description
Gegenstand der Erfindung ist ein Mehrscheibenisolierglas mit Randumfassung, z.B. als Kantenschutz, nach dem Oberbegriff des Anspruchs 1, insbesondere ein Brandschutzglas mit wenigstens einer vorgespannten Scheibe oder einer Scheibe aus Glaskeramik.The invention relates to a multi-pane insulating glass with a rim, e.g. as edge protection, according to the preamble of claim 1, in particular a fire protection glass with at least one toughened pane or a pane made of glass ceramic.
Mehrscheibenisolierglas besteht aus mindestens zwei Glascheiben, die durch einen am Rand zwischengefügten Steg auf Abstand gehalten werden. Der Steg bzw. Abstandshalter wird üblicherweise durch ein im allgemeinen aus Metall bestehendes Hohlprofil gebildet, in dem sich ein Trocknungsmittel befindet, welches über Öffnungen mit dem Zwischenraum zwischen den Scheiben in Verbindung steht. Der Steg bzw. Abstandshalter ist etwas nach innen versetzt, so daß in den Randbereich zwischen die Scheiben eine Dichtmasse eingebracht werden kann, die den Zusammenhalt der Scheiben und gleichzeitig die Abdichtung des Zwischenraumes gegenüber der Atmosphäre bewirkt. Für besonders hochwertige Abdichtungen wird zusätzlich zwischen Abstandshalter und Glas eine Dichtung, üblicherweise aus Butylkautschuk/ Polyisobuten, als Wasserdampfdiffusionssperre eingesetzt (z.B. DE-PS 36 37 064).Multi-pane insulating glass consists of at least two glass panes, which are kept at a distance by a web inserted between the edges. The web or spacer is usually formed by a generally metal profile, in which there is a desiccant, which is connected via openings to the space between the panes. The web or spacer is offset somewhat inwards, so that a sealing compound can be introduced into the edge region between the panes, which causes the panes to hold together and at the same time seals the intermediate space from the atmosphere. For particularly high-quality seals, a seal, usually made of butyl rubber / polyisobutene, is also used between the spacer and glass as a water vapor diffusion barrier (e.g. DE-PS 36 37 064).
Da die seitlich/außenliegenden Kanten des Glases bei unsachgemäßer Behandlung beschädigt, verkratzt oder zerbrochen werden können, z.B. wenn ein Fremdkörper wie ein Stein, Nagel oder dergleichen zwischen Glaskante bzw. -rücken und Unterlage (Klotzung) gelangt oder wenn das Glas unsanft oder auf eine sehr unebene harte Unterlage abgesetzt wird, ist es bekannt, die Kanten durch eine umlaufende als Kantenschutz wirkende Randumfassung vor Beschädigungen zu schützen. Als Kantenschutz bekannt sind Profilleisten aus Kunststoff, durch die der Rand der Verglasung eingefaßt ist, z.B. beschrieben in DE-PS 24 54 530, DE-PS 32 29 421 oder DE-OS 36 19 780.Since the side / outside edges of the glass can be damaged, scratched or broken if handled improperly, e.g. if a foreign body such as a stone, nail or the like gets between the glass edge or back and the base (blockage) or if the glass is rough or on a very uneven hard surface is deposited, it is known to protect the edges from damage by a circumferential edge edge acting as edge protection. Known as edge protection are plastic profiles, through which the edge of the glazing is bordered, for example described in DE-PS 24 54 530, DE-PS 32 29 421 or DE-OS 36 19 780.
Diese Profilleisten sind jedoch verhältnismäßig teuer und müssen genau der jeweiligen Dicke des Scheibenverbundes angepaßt sein, so daß eine verhältnismäßig aufwendige Lagerhaltung für Profilleisten mit den unterschiedlichen lichten Weiten erforderlich ist. Es hat sich ferner gezeigt, daß die an sich wünschenswerte Anbringung der Profilleisten unmittelbar nach der Produktion der Verglasung bei manchen Dichtmassen, z.B. solchen auf Silicon-Basis, nicht möglich ist und daß auch die umständliche nachträgliche Anbringung bei manchen Dichtmassen zu Langzeitschäden führt. Es ist auch bekannt, flexible gasundurchlässige Bänder für diesen Zweck einzusetzen (Cahiers du Centre Scientifique et Technique du Batiment, Nr. 241, Juli-August 1983, Seiten 1-9, Paris, FR, Avis Technique Nr. 6/82 - 223: "Avis sur le vitrage isolant ISO GIR).However, these profile strips are relatively expensive and must be adapted exactly to the respective thickness of the pane assembly, so that a relatively complex storage for profile strips with the different clear widths is required. It has also been shown that the attachment of the profile strips, which is desirable per se, immediately after the production of the glazing for some sealing compounds, e.g. silicone based, is not possible and that the cumbersome retrofitting of some sealants leads to long-term damage. It is also known to use flexible gas impermeable tapes for this purpose (Cahiers du Center Scientifique et Technique du Batiment, No. 241, July-August 1983, pages 1-9, Paris, FR, Avis Technique No. 6/82 - 223: "Avis sur le vitrage isolant ISO GIR).
Bei Brandschutzverglasungen kommen häufig Druckausgleichssysteme, wie sie z.B. in DE-OS 36 37 064 beschrieben sind, zur Anwendung. Diese Druckausgleichssysteme bestehen aus einem Ventil, welches sich im Brandfall öffnet und dadurch den innerhalb der Isolierverglasung durch die Temperaturerhöhung sich aufbauenden erhöhten Gasdruck abläßt, bevor dieser die Scheiben zum Bersten bringt. Für Scheiben mit Druckausgleichssystemen können Profilleisten als Kantenschutz: nur dann verwendet werden, wenn sie mit Bohrungen versehen werden, die mit den Öffnungen der Druckausgleichssysteme korrespondieren, was produktionstechnisch aufwendig ist. Es ist aus EP 202 555 A auch bekannt, als Kantenschutz ein flexibles Band aus einem an sich gasundurchlässigen Material zu verwenden, das an den Stellen für die Druckausgleichsöffnungen mit Löchern versehen ist.In fire protection glazing, pressure compensation systems such as those described, for example, in DE-OS 36 37 064 are often used. These pressure compensation systems consist of a valve that opens in the event of a fire and thereby releases the increased gas pressure that builds up inside the insulating glazing due to the temperature increase before it causes the panes to burst. For panes with pressure compensation systems, profile strips can only be used as edge protection if they are provided with holes that correspond to the openings in the pressure compensation systems, which is complex in terms of production technology. It is also known from EP 202 555 A to use, as edge protection, a flexible band made of a gas-impermeable material which is provided with holes at the points for the pressure equalization openings.
Die Aufgabe der Erfindung besteht darin, ein Mehrscheibenisolierglas mit einer preiswerten, als Kantenschutz geeigneten Randumfassung zu finden, mit der bei gleicher Größe auch unterschiedlich dicke Scheiben eingefaßt werden können, die bei der Verwendung von Dichtmassen, die unter Aufnahme von Feuchtigkeit aus der Luft und unter Abgabe von flüchtigen Reaktionsprodukten vernetzbar sind, unmittelbar nach der Herstellung des Scheibenverbundes angebracht werden kann, die keine Langzeitschäden verursacht und die auch problemlos bei Verglasungen mit Druckausgleichssystemen Verwendung finden kann.The object of the invention is to find a multi-pane insulating glass with an inexpensive edge protection suitable as edge protection, with which, with the same size, panes of different thicknesses can also be bordered when using sealing compounds which absorb moisture from the air and below Dispensing of volatile reaction products can be crosslinked, can be applied immediately after the pane assembly, which does not cause long-term damage and can also be used without problems in glazing with pressure compensation systems.
Diese Aufgabe wird durch das in dem Patentanspruch 1 beschriebene Mehrscheibenisolierglas gelöst.This object is achieved by the multi-pane insulating glass described in claim 1.
Abweichend von den bisher bekannten Ausführungsformen der Randumfassung, die aus einem vorgeformten, verhältnismäßig starren U-förmigen Profil oder einem Band aus undurchlässigem Material bestehen, besteht die als Kantenschutz dienende Randumfassung für das erfindungsgemäße Mehrscheibenisolierglas im Rohzustand aus einem flachen, flexiblen Band, das erst durch das Aufbringen auf den Rand des Glases seine endgültige Form erhält. Das Band besteht ferner aus einem gasdurchlässigen Material. Dadurch ist es erstmals möglich, auch solche Verglasungen direkt nach der Produktion mit dem Kantenschutz zu versehen, bei denen die Dichtmasse unter Aufnahme von Reaktionspartnern aus der Luft, im allgemeinen Wasserdampf, vernetzt. Bei diesen Mehrscheibenisoliergläsern handelt es sich insbesondere um Brandschutzisolierglas mit wenigstens einer vorgespannten Scheibe oder einer Scheibe aus Glaskeramik, bei denen aus Gründen des Brandschutzes Dichtmassen auf Siliconbasis verwendet werden. Auch die bei der Vernetzung der Dichtmasse freiwerdenden Reaktionsprodukte, im Fall des genannten Brandschutzisolierglases im allgemeinen Essigsäure, können durch das Kantenschutzband nach außen abgeführt werden.Deviating from the previously known embodiments of the edge surround, which consist of a preformed, relatively rigid U-shaped profile or a band made of impermeable material, the edge surround serving as edge protection for the multi-pane insulating glass according to the invention, in its raw state, consists of a flat, flexible band that is only through the application to the edge of the glass takes on its final shape. The band also consists of a gas-permeable material. Thereby For the first time, it is possible to provide edge protection for glazing directly after production, in which the sealant crosslinks by absorbing reactants from the air, generally water vapor. These multi-pane insulating glasses are in particular fire-resistant insulating glasses with at least one toughened pane or a pane made of glass ceramic, in which silicone-based sealing compounds are used for reasons of fire protection. The reaction products released during the crosslinking of the sealant, in the case of the above-mentioned fire-resistant insulating glass in general acetic acid, can also be removed to the outside through the edge protection tape.
Die Befestigung des Bandes an der Scheibe kann derart erfolgen, daß die Glaskanten und der Rand der Scheibe mit einem Klebstoff, z.B. der Dichtmasse an sich, bestrichen werden, worauf das Band angedrückt wird; bevorzugt wird jedoch, wenn das Band (einseitig) mit einer selbstklebenden Schicht versehen ist. Ist die ganze Breite des Bandes selbstklebend ausgerüstet, ist darauf zu achten, daß entweder der Klebstoff gasdurchlässig z.B. porös ist oder daß der Klebstoff nur punktuell, z.B. in einem Punkt-oder Streifenraster aufgetragen ist, so daß zwischen den Klebstoffinseln genügend nicht beschichtete Bandfläche vorhanden ist, die den Gasdurchtritt ermöglicht.The tape can be attached to the disc in such a way that the glass edges and the edge of the disc are glued, e.g. the sealing compound itself, are coated, whereupon the tape is pressed; however, it is preferred if the tape (on one side) is provided with a self-adhesive layer. If the entire width of the tape is self-adhesive, make sure that either the adhesive is gas-permeable e.g. is porous or that the adhesive is only sporadic, e.g. is applied in a dot or strip pattern, so that there is sufficient uncoated tape surface between the adhesive islands, which allows gas to pass through.
Eine weitere vorteilhafte Ausführung besteht darin, an der Stelle, die der Dichtmasse gegenüberliegt, d.h. normalerweise in der Mitte des Bandes, eine klebstofffreie Zone vorzusehen. Diese klebstofffreie Zone kann breiter oder schmaler sein als der vom Dichtmittel ausgefüllte Zwischenraum zwischen den Scheiben. Es muß bei einer schmaleren Zone nur sichergestellt sein, daß der Gasdurchtritt noch in ausreichendem Maße möglich ist.Another advantageous embodiment consists in that at the point opposite the sealing compound, i.e. usually in the middle of the tape to provide an adhesive-free zone. This adhesive-free zone can be wider or narrower than the space between the panes filled with sealant. With a narrower zone, it only has to be ensured that the passage of gas is still possible to a sufficient extent.
Als Material für das Band sind textile Substrate, insbesondere Gewebe-oder Filzbänder, aber auch Bänder aus Vlies geeeignet. Die textilen Substrate können aus organischen Fasern oder Fäden aus Baumwolle, Viskose, Wolle oder Kunststoff z.B.Polyestern usw. bestehen, wobei auch besonders brandfeste Fasern z.B. aus nachchloriertem PVC, Verwendung finden können. Geeignet sind insbesondere auch textile Substrate aus anorganischen Fasern, z.B. Glasfasern, weil sie preiswert und nichtbrennbar sind.Textile substrates, in particular woven or felt tapes, but also tapes made of nonwoven are suitable as the material for the tape. The textile substrates can consist of organic fibers or threads made of cotton, viscose, wool or plastic, for example polyester, etc., and particularly fire-resistant fibers, for example of post-chlorinated PVC, can also be used. Textile substrates made of inorganic fibers, for example glass fibers, are also particularly suitable because they are inexpensive and non-combustible.
Außer Bändern können auch gasdurchlässige Folien oder Papierstreifen Verwendung finden, die ebenfalls vorteilhafterweise selbstklebend ausgerüstet sein können. Die Folien oder das Papier können zusätzlich mit Perforationen versehen werden, die einen verbesserten Gasaustausch ermöglichen. Die Größe der Perforationen sollte so bemessen werden, daß keine oder möglichst wenig unausgehärtete Dichtmasse durchtreten kann. Besonders vorteilhaft sind Mikroperforationen, bei denen die Öffnungen so klein sind, daß zwar Wasserdampf, aber keine Wassertropfen durchtreten können. Papier wie auch das Folienmaterial kann auch in an sich bekannter Weise mit Verstärkungsfasern, z.B. Glas- oder Kunststoffasern versetzt sein.In addition to tapes, gas-permeable films or paper strips can also be used, which can also advantageously be equipped with self-adhesive. The foils or the paper can additionally be provided with perforations, which enable an improved gas exchange. The size of the perforations should be such that no or as little as possible uncured sealant can penetrate. Microperforations in which the openings are so small that water vapor but no water drops can pass through are particularly advantageous. Paper as well as the film material can also be reinforced with reinforcing fibers, e.g. Glass or plastic fibers can be offset.
Weiterhin ist es auch möglich, Bänder aus offenporigen Schaumgummi- oder Schaumkunststoffstreifen zu verwenden oder Bänder aus porösen Folien. Die Schaumstreifen und die Folien müssen weichmacherfrei sein, da sich gezeigt hat, daß die üblicherweise verwendeten Weichmacher langfristig die Haftung zwischen Scheibe und der Silicondichtmasse beeinträchtigen. Bei Dichtmassen, die weichmacherunempfindlich sind, braucht dieses Erfordernis nicht beachtet zu werden; die Bänder sind dann jedoch nicht mehr universell einsetzbar.Furthermore, it is also possible to use tapes made of open-pore foam rubber or foam plastic strips or tapes made of porous foils. The foam strips and the foils must be free of plasticizers, since it has been shown that the plasticizers usually used have a long-term effect on the adhesion between the pane and the silicone sealant. In the case of sealing compounds which are insensitive to plasticizers, this requirement need not be observed; however, the tapes can then no longer be used universally.
Die Bänder können auch metallisiert sein, was mitunter optische und technische Vorteile bieten kann.The strips can also be metallized, which can sometimes offer optical and technical advantages.
Die Stärke der Bänder soll so bemessen werden, daß die Bänder einerseits einen ausreichenden Schutz für die Kante der Scheibe bewirken, daß sie aber andererseits noch flexibel genug sind, um sich ohne Schwierigkeiten um die Kanten bzw. den Rand der Scheibe legen lassen. Je nach dem verwendeten Material kommen dabei Stärken von 0,05 bis 15 mm für das Band infrage. Bei der Verwendung von textilen Bändern aus organischen Fasern liegen die Bandstärken etwa zwischen 0,1 und 1,0 mm, bei der Verwendung von textilen Bändern aus anorganischen Fasern etwa zwischen 0,1 und 0,8 mm; Folien und Papier werden im allgemeinen mit Stärken von 0,05 bis 0,8 mm eingesetzt und Schaumfolien sollen, je nach mechanischer Härte des Schaumes, etwa zwischen 0,2 und 15 mm dick sein. Die Breite der Bänder soll so groß sein, daß die Bänder bzw. Kanten der Scheiben sicher, d.h. ohne Gefahr des Ablösens des Bandes vom Scheibenrand, umfaßt werden. Die Breite soll jedoch nicht so groß sein, daß das Band nach dem Einbau der Scheibe in den Fensterrahmen aus dem Rahmenfalz hervorsieht. Im allgemeinen soll das Band den Rand der Scheibe um jeweils etwa 15 mm umgreifen. Dabei kann das Band auch unsymmetrisch angeordnet sein, wenn dies für wünschenswert gehalten wird. Eine Bandbreite kann bei verschiedenen Scheiben mit unterschiedlichen Dicken Verwendung finden, da bei einer Variation der Scheibendicke um z.B. 5 mm der Überstand des Bandes auf den Scheibenflächen sich nur um je 2,5 mm ändert.The thickness of the strips should be such that the strips on the one hand provide adequate protection for the edge of the pane, but on the other hand they are still flexible enough to be easily placed around the edges or the edge of the pane. Depending on the material used, thicknesses of 0.05 to 15 mm are possible for the tape. When using textile tapes made from organic fibers, the tape thicknesses are between 0.1 and 1.0 mm, when using textile tapes made from inorganic fibers about 0.1 to 0.8 mm; Foils and paper are generally used with a thickness of 0.05 to 0.8 mm and foam foils should, depending on the mechanical hardness of the foam, be between about 0.2 and 15 mm thick. The width of the strips should be so large that the strips or edges of the disks are secure, ie without risk of detachment of the tape from the edge of the disc. However, the width should not be so large that the tape looks out of the frame rebate after the pane has been installed in the window frame. In general, the tape should encompass the edge of the disk by about 15 mm each. The band can also be arranged asymmetrically if this is considered desirable. A band width can be used with different panes with different thicknesses, because if the pane thickness is varied by, for example, 5 mm, the overhang of the band on the pane surfaces changes by only 2.5 mm.

Das in Fig. 1 dargestellte Zweischeibenisolierglas besteht aus den beiden Glasscheiben 1 und 2, die durch ein als Abstandshalter dienendes Hohlprofil 3 in dem gewünschten Abstand voneinander gehalten werden. In dem Hohlprofil 3 befindet sich ein Trocknungsmittel 4 in Granulatform. Der Gasaustausch zwischen dem Trocknungsmittel 4 und dem Zwischenraum 6 zwischen den Scheiben 1 und 2 erfolgt über Perforationen 5. Das Hohlprofil 3 ist gegenüber dem Scheibenrand etwas zurückversetzt, um eine Fuge für die Aufnahme der Dichtmasse 7, mittels derer die Scheiben 1 und 2 miteinander verklebt und nach außen abgedichtet werden, zu bilden. Als Dichtmasse 7 wird bevorzugt eine mit der Luftfeuchtigkeit reagierende und dadurch vernetzende Silicondichtmasse verwendet, bei der die Reaktion mit der Luftfeuchtigkeit unter Abgabe von Essigsäure verläuft. Als zusätzliche Gasdiffusionssperre zwischen Außenluft und dem Scheibenzwischenraum 6 sind zwischen Hohlprofil 3 und den Scheiben 1 und 2 Dichtstreifen 8 und 8′ aus Butylkautschuk vorgesehen. Die als Kantenschutz dienende Randumfassung 9 besteht aus einem Baumwollgewebeband, das mit einer gasdurchlässigen Klebstoffschicht versehen ist und um die Kanten der Scheiben 1 und 2 sowie über die Dichtmasse 7 geklebt ist. Die Klebstoffschicht ist nicht gesondert dargestellt. Als Klebstoff für die Randumfassung 9 sind alle denkbaren Klebstoffe geeignet, solange sie eine ausreichend feste Verbindung der Randumfassung 9 mit den Glasscheiben ermöglichen und bei Kontakt mit der Dichtmasse 7 keine schädlichen, den Scheibenverbund beeinträchtigenden Reaktionen eingehen. Die Randumfassung 9 ist unterschiedlich weit um die Kanten herumgezogen und übergreift den Scheibenrand auf der rechten Seite weiter als auf der linken Seite.The double-pane insulating glass shown in FIG. 1 consists of the two
Die Figuren 2 und 3 zeigen Abschnitte von als Randumfassung geeigneten Bändern vor dem Anbringen an der Scheibe und zwar auf die Klebstoffseite gesehen. Das Band gemäß Figur 2 besteht aus einem Gewebeband; die selbstklebende Beschichtung ist in schräg zur Bandlaufrichtung verlaufenden Streifen 10 aufgebracht. Die zwischen den Klebstoffstreifen 10 liegenden klebestofffreien Bereiche des Bandes erlauben einen ausreichenden Gasdurchtritt, so daß die Vernetzung des Dichtmittels und die Abfuhr der bei der Vernetzung entstehenden Reaktionsprodukte sichergestellt ist. In Figur 3 ist ein Band dargestellt, das aus einer gasnudurchlässigen Folie besteht und einseitig vollständig mit einer selbstklebenden Beschichtung versehen ist. Der Gasaustausch zwischen der Dichtmasse und der Atmosphäre wird hier über die Perforationen 11 verbessert, die mittig in dem Band angeordnet sind und die bei Anbringen des Bandes an der Scheibe in dem Bereich des Dichtmittels verlaufen. Die Klebstoffschicht ist hier nicht gesondert dargestellt.FIGS. 2 and 3 show sections of tapes which are suitable as peripheral edging before being attached to the pane, to be precise seen on the adhesive side.
