Description
Die vorliegende Erfindung betrifft einen Fensterrahmen mit einem sehr geringen Wärmedurchgangskoeffizienten. 5The present invention relates to a window frame with a very low heat transfer coefficient. 5
Das besondere Merkmal des erfindungsgemäßen Fensterrahmens besteht darin, daß der Randverbund des Fensterglases im wesentlichen vollstänig und umlaufend in Schaum eingebettet ist. Vorzugsweise wird erfindungsgemäß auch der Rahmenfalzraum zumindest teilweise ausgeschäumt. Besonders vorteilhaft ist es jedoch, wenn der gesamte Rahmenfalzraum ausgeschäumt ist.The special feature of the window frame according to the invention is that the edge connection of the window glass is essentially completely and all around embedded in foam. Preferably, according to the invention, the frame rebate space is also at least partially filled with foam. However, it is particularly advantageous if the entire frame rebate space is filled with foam.
Die im wesentlichen vollständige und umlaufende Einbettung in Schaum führt dazu, daß der Randverbund des Glases gegenüber dem Rahmenmaterial im wesentlichen dampfdicht und wärmeisolierend gedämmt ist. Außerdem verhindert die Einbettung des GlasrandVerbundes in eine Schaumumrandung den Zutritt von Umgebungsluft sowohl vom Innenraum als auch von Außen.The essentially complete and all-round embedding in foam means that the edge connection of the glass is essentially vapor-tight and heat-insulated compared to the frame material. In addition, the embedding of the glass edge connection in a foam border prevents the ingress of ambient air from both the interior and the exterior.
Der erfindungsgemäß zur Einschäumung des Glasrandverbundes sowie zur Ausfüllung des Rahmenfalzraumes verwendete Schaum ist vorzugsweise geschlossenporig und wasserdampfdicht. Sein Aufschäumungsvermögen ist vorzugsweise so gewählt, daß er gegebenenfalls den gesamten Rahmenfalzraum lunkerfrei ausfüllen kann.The foam used according to the invention for foaming the glass edge joint and for filling the frame rebate space is preferably closed-pored and water vapor-tight. Its foaming capacity is preferably selected so that it can fill the entire frame rebate space without any cavities if necessary.
Ein weiteres wesentliches Merkmal der vorliegenden 0 Erfindung besteht darin, daß der Einstand des Glasrandverbundes gegenüber dem Rücken des FensterrahmensAnother essential feature of the present invention is that the recess of the glass edge composite relative to the back of the window frame
zumindest etwas abgesenkt ist. Durch diese Maßnahme wird ein Wärmedurchgang durch die Glasscheibe erheblich erschwert, da eine Wärmeleitung durch den Abstandshalter nahezu vollständig unterdrückt wird. 5is at least slightly lowered. This measure makes heat passage through the glass pane considerably more difficult, as heat conduction through the spacer is almost completely suppressed. 5
Eine weitere Maßnahme zur Erschwerung des Wärmedurchganges besteht darin, daß erfindungsgemäß das Ende der Glasscheibe zumindest etwas unterhalb des Fensterrahmenrückens liegt und der Abstandhalter nicht auf Höhe des Glasscheibenendes, sondern zumindest teilweise im wesentlichen unterhalb des Glasscheibenendes vorgesehen ist.A further measure to make heat transfer more difficult is that, according to the invention, the end of the glass pane is located at least slightly below the back of the window frame and the spacer is not provided at the height of the glass pane end, but at least partially substantially below the glass pane end.
In der Regel ist der Abstandhalter zur Beabstandung der Glasscheiben in Form eines Hohlprofiles mit rechteckiger, quadratischer, ovaler oder runder Querschnittsfläche ausgebildet. Alternativ hierzu kann er die Form eines Buchstabens „U" oder „V" oder eines um 90° zur Seite geneigten Buchstabens „C" aufweisen. In besonders bevorzugten Ausführungsformen ist der innere Hohlraum dieser Profile mit einem pulverförmigen Trockenmittel gefüllt oder auf der Innenseite mit einem Trockengelstreifen versehen.As a rule, the spacer for spacing the glass panes is designed in the form of a hollow profile with a rectangular, square, oval or round cross-sectional area. Alternatively, it can have the shape of a letter "U" or "V" or a letter "C" inclined to the side by 90°. In particularly preferred embodiments, the inner cavity of these profiles is filled with a powdered desiccant or provided with a drying gel strip on the inside.
Insbesondere in dem Fall, daß der Abstandhalter im wesentlichen der Form eines um 90° zur Seite geneigten Buchstabens „C" entspricht, welcher im äußersten Bereich der Scheiben vorgesehen ist, ist in den beiden oberen, außen liegenden Bereichen jeweils mindestens eine sich 0 entlang der Längsachse des Abstandhalters erstreckende Nut vorgesehen. Selbstverständlich ist es möglich anstelleIn particular, in the case where the spacer essentially corresponds to the shape of a letter "C" inclined at 90° to the side, which is provided in the outermost region of the panes, at least one groove extending along the longitudinal axis of the spacer is provided in the two upper, outer regions. Of course, it is possible to use
einer Nut auf jeder Seite auch zwei oder sogar mehrere Nuten jeweils übereinanderliegend vorzusehen. In diese Nuten kann eine Dichtungsmasse eingefüllt sein. Die knapp oberhalb und unterhalb der Dichtungsnut liegenden Außenbereiche des C-förmigen Abstandhalters können mit der jeweiligen Glasinnenseite in im wesentlichen linienförmigen Kontakt kommen. Vorzugsweise wird jedoch zur Vermeidung einer Wärmeleitung ein Kontakt zwischen der Glasinnenseite und dem Körper des C-förmigen Abstandhalters beispielsweise durch einen Dichtungssmaterial-Wulst vermieden, indem man die Glasinnenseite durch einen derartigem Dichtungsmaterial-Wulst zumindest etwas von dem Körper des C-förmigen Abstandhalters beabstandet. Der randseitige und glasseitige Bereich unterhalb der Dichtungsnut wird vorzugsweise mit einem gasdichten Dichtstoff abgedichtet.a groove on each side, two or even more grooves can be provided, one above the other. A sealing compound can be filled into these grooves. The outer areas of the C-shaped spacer, which are located just above and below the sealing groove, can come into essentially linear contact with the respective inside of the glass. However, to avoid heat conduction, contact between the inside of the glass and the body of the C-shaped spacer is preferably avoided, for example by means of a sealing material bead, by spacing the inside of the glass at least somewhat from the body of the C-shaped spacer by means of such a sealing material bead. The edge and glass-side area below the sealing groove is preferably sealed with a gas-tight sealant.
Von besonderem Vorteil hat sich herausgestellt, wenn mindestens eine Dampfsperre oder Dampfbremse im Bereich derjenigen Rahmenaußenseite vorgesehen ist, welche dem höherem Dampfdruck ausgesetzt ist.It has proven to be particularly advantageous if at least one vapor barrier or vapor retarder is provided in the area of the outside of the frame which is exposed to the higher vapor pressure.
In bevorzugten Ausführungsformen umfaßt der erfindungsgemäße Fensterrahmen auf der dem Innenraum zugewandten Seite eine Glashalteleiste, welche mit der Außenseite der inneren Glasscheibe lediglich in im wesentlichen linienförmigen Kontakt steht.In preferred embodiments, the window frame according to the invention comprises a glass retaining strip on the side facing the interior, which is only in essentially linear contact with the outside of the inner glass pane.
Dieser linienförmige Kontakt liegt vorzugsweise im wesentlichen auf der Höhe des Abstandhalters. Der linienförmige Kontakt der Glashalteleiste an derThis linear contact is preferably located essentially at the height of the spacer. The linear contact of the glass retaining strip on the
Außenseite der inneren Glasscheibe wird durch eine Abschrägung des oberen Abschnittes der Glashalteleiste einerseits und eine Auskehlung des unteren Abschnittes der Glashalteleiste andererseits ermöglicht.The outside of the inner glass pane is made possible by a bevel of the upper section of the glass retaining strip on the one hand and a groove of the lower section of the glass retaining strip on the other hand.
Das Volumen der unteren Auskehlung wird vorzugsweise zur Vermeidung eines Wärmetransportes durch Strahlung oder Leitung ausgeschäumt.The volume of the lower groove is preferably filled with foam to avoid heat transport by radiation or conduction.
Die Querschnittsfläche der Glashalteleiste fällt folglich zu dem Linienkontakt von oben her schräg ab und weist unterhalb des Linienkontaktes eine Auskehlung auf.The cross-sectional area of the glass retaining strip therefore slopes downwards towards the line contact and has a groove below the line contact.
Die Verfüllung des Zwischenraumes zwischen der oberen Abschrägung und der Glasoberfläche erfolgt in der Regel durch eine wasserdichte und/oder dampfdichte und/oder UV-beständige Dichtmasse mit einem ausgeprägten Adhäsionsvermögen gegenüber Glas und dem Rahmenmaterial.The gap between the upper bevel and the glass surface is usually filled with a waterproof and/or vapor-tight and/or UV-resistant sealant with a strong adhesion to the glass and the frame material.
Es wird ausdrücklich darauf hingeweisen, daß der erfindungsgemäße Fensterrahmen grundsätzlich aus jedem beliebigen Material bestehen kann, insbesondere aus Holz, Kunststoff, Metall und Keramik.It is expressly pointed out that the window frame according to the invention can basically consist of any material, in particular wood, plastic, metal and ceramic.
Zur Vermeidung des Einströmens von Umgebungsluft durch die Verbindungsstelle zwischen der Glashalteleiste und dem darunterliegenden Abschnitt des Fensterrahmens ist es empfehlenswert, unterhalb der Glashalteleiste ein dampfdichtes Material vorzusehen.To prevent ambient air from entering through the connection point between the glazing bead and the section of the window frame below, it is recommended to provide a vapor-tight material underneath the glazing bead.
Die Glashalteleiste kann an dem Fensterrahmen beispielsweise mittels Nägeln und/oder Schrauben und/oder 0 eines Klettverschlusses und/oder einer Verklebung und/oder eines mechanischen Einstecksystems mit Nut und FederThe glass retaining strip can be attached to the window frame, for example, using nails and/or screws and/or 0 a Velcro fastener and/or an adhesive and/or a mechanical insertion system with tongue and groove
befestigt werden.be attached.
Zusammenfassend ist festzustellen, daß im Rahmen der vorliegenden Erfindung ein Fensterrahmensystem bereitsgestellt wird, welches aufgrund der Umschäumung des Glasrandverbundes die Kondensation von Luftfeuchtigkeit an dem Glasrandverbund ausschließt. Hierdurch wird es erstmalig möglich, selbst sehr gut isolierende Glasscheiben mit einem K-Wert im Bereich von 0,7 unter Umgehung des Kondensationswasserproblemes einzubauen. Kondenswasser wird durch Kondensation der aus der Umgebungsluft stammenden Feuchtigkeit im Bereich des Randverbundes des Glases nicht gebildet und läuft nicht mehr tropfenförmig von dem Randverbund des Glases nach unten in den Falzraum ab. Das Problem einer Fäulnisbildung in dem Falzraumn, welches insbesondere die Lebensdauer von Holzfensterrahmen negativ beeinflußt, gehört somit der Vergangenheit an.In summary, it can be stated that within the scope of the present invention, a window frame system is provided which, due to the foam encapsulation of the glass edge joint, prevents the condensation of air humidity on the glass edge joint. This makes it possible for the first time to install even very well insulating glass panes with a K value in the range of 0.7, while avoiding the problem of condensation. Condensation is not formed by condensation of the moisture from the ambient air in the area of the edge joint of the glass and no longer runs down in droplets from the edge joint of the glass into the rebate space. The problem of rot forming in the rebate space, which has a negative impact on the service life of wooden window frames in particular, is therefore a thing of the past.
