OBJECTS AND SuHH~Rx-QE TH~ I~VENl59N
A first object of the present invention is to provide a heat insulating, double-pane glass which is not only insulating, but also decorative due to the presence of a decorative pane extending all over its surface between the glass panes.
Another object of the invention is to provide an insUlated door incorporating a decorative glass window, wherein this glass window is made from a decorative, heat-insulating double-pane glass acaording to the invention.
The above mçntionsd first object o~ the invention i8 achieved with a heat insulating, double-pane glass of the type compri~es a pair of parallel glass panes of a given surface held in spaced apart relationship by an edging frame and, in combination therewith, at least one layer ~f a clear, low emissivity, wavelength selective or heat-reflective material extending all over the ~urface ~f the glass panes. In accordance with the invention, this basic structure which is known per se is improved so that it ~urther comprises at least one decorative pane mounted within the double-pane glass between and parallel to the 207~68~
glass panes, this at least one decorative pane extending all over the surface of the glass and being held therein by the edging frame.
The above mentioned second object of the invention is achieved with an in~ulated door provided with a decorative glass window, wherein the window is nade of an improved heat-insulating double pane glas~ as defined hereinabove.
~BIEF ~s~BI~TLQ~ OF TH~ DRAWIN~S
The invention will be better underætood upon reading of the following non-restrictive description of several embodiments thereof, made with reference to the accompanying drawings in which:
Fig. l is a cross-section view of a decorative, heat insulating double-pane glass according to a first embodiment of the invention;
Fig. 2 is a cro6s-section view of a decorative, heat insulating double-pane glass according to a second embodiment of the invention;
Fig. 3 is a cross-sectional view of a decorative, heat insulating double-pane glass according to a third embodiment of the invention; and Fig. 4 is a perspective view of an insulated door provided with a decorative glass window according to the invention.
DESCRIPTION OF S~VERAL PREFERRED EMBQ~ wrs As already explained hereinabove, the invention ba~ically consists in incorporating at least one decorative pane, such as a leaded or stained glass work of conventional structure within a heat-insulating double-pane glass, also of cbnventional structure to obtain a double-pane glass which i5 not only heat insulating but also decorative.
In accordan~e with a first embodiment of the 2071~2 invention as shown in fig~ l, there i8 provided a heat-insulatinq doubl~-pane glas6 l comprising a pair of parallel glass panes 3 and 5 of a given surface, held in spaced apart relationship by an edging frame 7 of conventional structure. At least one layer 9 of a clear, colorless, low-emlssivity, wavelength selective or heat-reflective material is applied in the form a coating onto one of the glass panes, say 5, within the double-pane glass l.
This basic structure is already known and presently available in the market under the trademark SOLATEC (Hyalin Inc.).
When the heat-reflective coating 9 is applied onto the glass pane which is located outside the building, heat reflects off the surface of the glass an important quantity of solar energy, thus ~ontributing to reduce air conditioning cost. During the winter time, the same coating reduces it lost, thus saving in heating cost.
When the same coating is applied onto the glass pane that is located inside the building, it reduces solar heat gain in the summer because it acts as an infra red barrier, and it reduces the interior heat lost in the winter.
In both cases, the use of such coating applied onto one of the glass panes allows reduction of heating cost in the winter and air conditioning cost in the summer.
As aforesaid, double-pane glasses incorporating such a coating are already available in the market.
Accordingly, no further description thereof i8 actually necessary, except to specify that, usually, the coating that is applied is o~ the metallic type and comprises three layers, namely an anti-reflective bottom coat, a heat reflective middle-coat and a final anti-reflective 2~7~82 top coat which is also a protectivs coat.
In ac~ordance with the invention, this basic structure is improved in that at least one decorative pane ll is mounted within the double-pane glass l, between and parallel to the glass panes 3 and 5. This decorative pane may be of any type. It may be a glass work, a leaded glass work ~as shown in the drawings), stained glass work or anyther kind of decorative pane conventionally used in windows~
In accordanae with the invention, this decorative pane ll e~tends all over the surface of the double pane glass l and i8 held within the same by the edging frame 7.
To improve the in~ulation of such a double pane glass, the glass panes 3 and 5 and their edging frame 7 may be sealed to form a close space and this space may be filled up with an inert gas, such as argon.
The decorative, heat insulating double-pane glass l shown in fig. 1 has a thermal resistance "R" which is twice the one of a decorative, double-pane glass of the same size and basic structure. Assuming that the thermal resistance of such a conventional glass is equal to 2 per inch, the thermal resistance of the decorative, heat-insulating double pane glass l disclosed hereinabove will be for the very same kind and size of window, equal to 4 per inch.
The decorat~ve, heat insulating double-pane glass l' according to the second embodiment of the invention as shawn in fig. 2 al~o comprises a pair of parallel glass panes 3' and 5' held in space apart relationship by an edging frame 7'. It also comprises a sheet 9' of a clear, colorless, low emissivity, heat reflective coating applied onto a clear plastic film, in order to improve its insulating property.
An example of such a composite sheet is disclo~ed, by way of example in U.S~ patent No. 4,799,745 issued January 24, 1989 to SOUTHWALL T~CHNOLOGIES INC.
This sheet 9' i~ held by the ~dging frame 7~ between the glass panes 3' and 5' and define within the dou~le pane glass two distinct air spaces A and B.
Once again, this basic structure is known and presenly available onto the market under the trademark HEAT MIRROR (Southwall Technologies Inc.).
This structure is particularly advantageous in that it combines two distinct air spaces blocking heat flow due to the conversion and conduction, with a central, low emissivity, wavelength sele¢tive coating applied onto a plastic film which blocks radiant heat transfer and solar heat gain. ~s a matter of fact, this structure makes the insulating double-pane glass virtually non-distinguishable in weight and appearance for a conventional double pane glass but which has substantially improved ther~al performance.
Once again, in accordance with the invention, this basic structure is improved in that it further incorporates at least one decorative pane 11' located in one of the two air spaces, say A.
once again, the resulting structure has a thermal resistance "R" which is more than twice the one of a similar decorative double pane glass of the same size and thickness. Assuming that the thermal reæistance of such a conventional decorative glass pane i8 equal to 2 per inch, the thermal resi~tance of the decorative, heat insulating glass pane 1' as shown in fig. 2 will be e~ual to 4.5 per inch.
The heat insulating, double pane glass 1"
according to the third embodiment of the invention as shown in fig. 3, also comprises a pair of parallel glass 2071~82 panes 3" and 5" of a given surface, held in space apart relationship by an edging frame 7". The glass panes and their edging frame are sealed. To make this double-pane glass heat insulating, two sheets 9" of a clear, colorless, low emissivity, heat reflective coating applied onto a clear plastic film are mounted within the double pane glass to define therein three distinct air spaces C, D and E that are filled up with an inert gas, such as krypton.
The heat in~ulating sheets 9" may be identical to the one disclosed hereinabove, which is sold under the trademark HEAT MI~ROR.
once again, this heat-insulating double-pane glass structure is already known and presently offered for sale both in Canada and the United States under the trademark SUPERGLASS (Southwalls Technologies Inc.).
once again, in accordance with the invention, this double plane glass structure is improved in that it further comprises a decorative pane 11" mounted in, say, the airspace C, the pane 11" extending all over the surface of the double-pane glass and being held by the edglng frame 7".
once again, the thermal resi~tance of the resulting structure is sub3tantially improved as compared to the thermal resistance of a decorative, double pane glass of the very same size and thickness. Assuming that the thermal resistance of the conventional decorative double pane glass i8 equal to 2 per inch, the thermal resistance of the decorative, insulating double pan glass 1" as shown in fig. 3 will be 8 per inch.
As was already explained hereinabove, the decorative, heat insulating double pane glass according to the invention may be used as a decorative glass window, especially for insulated door. An example of insulated 207~682 door provided with a decorative glass window made of an improved heat-insulating double-pane glass according to the invention is shown in fig. 4. Calculation made by the inventors have proved that if use is made of an improved, double-pane glass according to the invention as a window in a door as shown in fig. 4 instead of a conventional, decorative double-pane glass, tne resulting energy saving may be as high as 66% depending on the kind of insulation of the heat-insulating, d~uble pane glass that i8 being used.
It has also been found that dramatic energy savings may also be achieved if, instead of using insulated doors of conventional structure, having a thickness of 1 3/4 inches, use is made of insulated doors slightly thicker, that is with a thickness of at least 2 inches and preferably 2 1/4 inches.
Of course, modifications can be made to the structures disclosed hereinabove without departing from the scope of the present invention as reflected in the appended claims.
More particularly, the invention is concerned with the incorporation of a decorative glass pane into a heat insulating, double-pane glass of conventional structure, in order to make this double pane glass not only heat insulating, but also decorative.
The invention is also concerned with an insulated door provided with a decorative glass window made of a decorative, heat-insulating double-pane glass according to the invention.
b) ~escription of the prior art There exist presently on the market two different types of double-pane glasses that are commonly used to manufacture windows, especially for doors.
The first type of double-pane glass that is essentially used for decorative purpose, comprises a pair of parallel glass panes held in spaced apart relationship by an edging frame. A decorative pane which is usually a glass-work that may be leaded or stained is mounted within the double-pane glasses ~etween the glass panes. The resulting structure has a very nice look that makes it very attractive for decoration purpose.
