Definitions

• the invention relates to an encapsulated multiple sheet or insulating glass glazing unit and method of fabricating the same.
• Multiple glazing units generally comprise two or more sheets of glass spaced from one another to provide an insulating air space in the zone between the facing surfaces of the sheets. This air space is effective to reduce the transmission of heat energy through the unit due to conduction and convection.
• the sheets of glass are spaced from each other by a metal marginal edge spacer element extending around the periphery of the glass sheets.
• the glass sheets are generally adhered to the spacer element by a mastic composition forming a continuous film around the marginal edges of the sheets, between each sheet and the spacer element, to produce a primary hermetic seal.
• the spacer element is typically formed to hold a desiccant. Openings may be provided in the spacer element to establish communication between the air space of the unit and the desiccant so that moisture from the air within the unit may be absorbed by the desiccant.
• a resilient moisture resistant spacer element having a layer of mastic adhered thereto is preferably disposed around the peripheral edges of the glass sheet and the spacer element to provide a secondary hermetic seal.
• a channel member of substantially U-shaped cross-section is preferably affixed around the periphery of the unit to protect the peripheral edges of the glass sheets forming the unit.
• a conventional method of assembling multiple glazed units involves the application of the layer or bead of mastic that forms the primary hermetic seal along two opposite sides of the metal spacer element which is adapted to engage the inner facing surfaces of the glass sheets about the marginal edges thereof.
• the spacer element is then disposed between two preformed glass sheets, and the sheets are thereafter pressed together to cause the sheets to adhere to the spacer element and seal the internal air space between the facing surfaces of the sheets from the. atmosphere.
• the final air space between the two sheets of glass is a function of the thickness of the spacer element and the thickness of the mastic layers between each side of the spacing element and the adjacent glass sheet.
• a channel member formed of metal, such as stainless steel, for example, is thereafter affixed around the periphery of the unit.
• the angle that the flanges or sides of the channel member form with the central or web portion of the channel member is slightly less than 90 degrees.
• U.S. Patent No. 2,624,979 Another type of multiple glazed unit and method of forming the same is illustrated and described in U.S. Patent No. 2,624,979.
• the structure therein described employs at least two spaced apart sheets of glass wherein the peripheral edges of the top sheet are heated until they soften sufficiently to cause them to sag into contact the facing peripheral surface of the adjacent lower sheet.
• the glass in the region of contact at the marginal areas is heated to affect *a sufficient degree of softening to cause a fusion between the mating glass surfaces to form a continuous weld around the innermost zone.
• the unit is then typically annealed and finally may be placed in a preformed frame assembly preparatory to being mounted in an opening of a building, for example.
• the manufacture of the above multiple glazed insulating glass units requires a number of manufac uring and handling steps, preparatory to being ready for insertion into a building opening.
• this invention relates to a multiple glazed structure and method of fabricating such structure.
• this invention contemplates a multiple glazed unit including at least a pair of spaced apart sheets of frangible glazing material, and a polymeric frame adhered to predetermined portions of the peripheral marginal edges of the sheet material to produce a hermetically sealed zone between the facing surfaces of the sheet material, the frame material having been polymerized and cured in contact with the sheet material and having assumed by the autogenous pressure incident to its polymerization, while confined, intimate contact with the portions of the sheet material to which it is adhered.
• this invention contemplates the method of fabricating a multiple glazed unit which includes the steps of positioning at least a pair of optically transparent glass sheets in superposed spaced relation; introducing spacer means to define a zone between opposed facing surfaces of the sheets; providing a mold cavity in surrounding and overlapping relation to the peripheral marginal edges of the superposed spaced sheets; injecting into the mold cavity a composition which is capable of polymeriza ion and curable to produce a frame about the marginal edges of the sheets to hermetically seal the zone between the facing surfaces of the sheets; controlling the pressure at which the composition is injected into the cavity to one sufficiently low that the sheet material is not damaged; controlling the temperature of the mold cavity, the injection of the composition, and the amount of the composition injected so that the composition polymerizes, after its injection, develops intimate contact with the mold cavity and with the sheet material, and cures while in such contact; and removing the assembly from the mold cavity.
• the invention contemplates an optically transparent insulating assembly which can readily be installed with facility into the opening of a structure.
• the mechanism for effecting the hermetic seal between the facing surfaces of transparent sheet material simultaneously functions as means to maintain the desired spacing of the individual sheets one from another structurally bond the sheets together, and functions as an architectural frame having any desired dimensional configuration and decorative appearance.

• the insulating unit 10 includes a pair of sheets of glass, indicated by reference numerals 12 and 14, which are maintained in spaced relation by an elongate spacer strip unit 17.
• the spacer strip unit 17 is adapted to form a continuous band around the marginal edges of the facing surfaces of the glass sheets 12 and 14 to effectively form a dead air space 20 between the glass sheets 12 and 14.
• the entire assembly is framed by a formed frame member 22 of a polymeric material which is polymerized and cured in situ to encapsulate the marginal peripheral edge portions of the assemblage.
• the frame member 22 is typically formed by a reaction injection molding process.
• Fig. 3 shows the spacer strip unit 17 which may be employed in the embodiment illustrated by Figs. 1 and 2.
• the edge spacer unit 17 is- commercially available from Tremco Ltd. , Cleveland, Ohio, U.S.A. and sold under the Trademark "Swiggle Strip”.
• the spacer strip unit 17 consists of a self-contained spacer member 16 which may be any flexible, yet rigid material, such as corrugated aluminum and a desiccant containing material 18.
• the desiccant containing material 18 is formed of an extruded butyl based mastic containing a powdered molecular sieve desiccant dispersed throughout. Any combination of mastic and desiccant can be used which possesses properties suitable for employment in this invention.
• These properties could include, for example, chemical compatibility with the other components of the invention, ability to adhere to the sheet, frame and spacer strip materials, facility in assisting in forming and maintaining a hermetic seal, stability over a wide range of application conditions, and the capacity to prevent condensation formation in the associated hermetically sealed area.
• the initial step in producing the multiple glazed unit 10 involves the appropriate cleaning of the front and rear surfaces, and peripheral edges of the glass sheets 12 and 14 to prepare the surfaces for adherence with material to be employed for the frame member 22.
• the next step in producing the unit 10 is the application of a primer coating to the previously cleaned glass surfaces. Satisfactory results can be achieved by initially employing a primer layer 24 of a product such as "Betaseal, Glass Primer 435.18 Commercial Grade" commercially available from Essex Chemical Company, Clifton, New Jersey, U.S.A.
• the glass bond area is initially wiped with the primer to form the layer 24 which functions as a coupling agent.
• the primer material is a clear moisture-sensitive primer comprising gamma-aminopropy1triethoxys ilane , which promotes adhesion between other Betaseal products and glass.
• Primer layer 26 assists the rapid formation of a hydrolytically stable bond between the glass and associated frame 22 o-f polyurethane , for example.
• the material comprising layer 26 is a primer, such as for example, a blackout primer, which functions to prevent ultraviolet degradation of sealants and adhesives, or a primer to be used in conjunction with a frame 22 which may itself be a stable polyurethane .
• a blackout primer is commercially available under the description "Betaseal, Glass Primer 435.20 Commercial Grade" from Essex Chemical Company.
• the final assemblage may be commenced. This period of time is necessary to allow sufficient reaction and drying of the primers. The precise period of time required is dependent upon the particular primers used.
• the glass sheet 12 is placed in a die cavity of an associated mold. The mold is a part of an apparatus subsequently described in detail with reference to the material illustrated in Figs. 4 through 9.
• the spacer strip unit 17 is disposed, in continuous fashion, around the peripheral marginal edge portion of the glass sheet 12. Then, the glass sheet 14 is disposed in superposed relation over and aligned with the sheet 12.
• the spacer strip unit 17 functions to space the facing surfaces of the glass sheets 12 and 14 from one another at a predetermined desired distance, as well as cooperate to define a dead air space 20.
• An associated mold element having a mold cavity formed therein to cooperate with the aforementioned cavity, is then placed over the lower mold and locked in a closed position.
• a charge of polyurethane reaction mixture is injected into the mold cavity to form a completely encircling frame member 22.
• the coating 28 can be a urethane based paint, containing any desired decorative color producing component such as pigment, for example.
• a type of urethane based paint useful for such purpose is one manufactured by PPG Industries, Inc. , Pittsburgh, Pennsylvania, U.S.A., under the designation Purethane 700 HSE-848, for example.
• the paint coating 28 is then typically baked at approximately 140° - 150° F. for about 20-30 minu es.
• the layer 28 may function to protect the exposed polyurethane material forming the frame 22 from degradation which would otherwise be caused by exposure to ultraviolet radiation normally present in unfiltered sunlight. In the event the frame 22 is composed of an ultraviolet stable polyurethane material, the layer 28 may not be necessary, however it could be applied for decorative purposes.
• the frame 22 of the preformed structure 10, above described, functions to insure the desired dead air space between the facing surfaces of the glass sheets 12 and 14 and holds the peripheral edges of the glass sheets 12 and 14 in tightly compressed state against the spacer strip unit 17.
• the frame 22 may be formed in any desired cross -sec ional configura ion to accommodate existing window framing members of the double hung variety, as well as any other framing members.
• Fig. 10 shows an alternative embodiment of the structure illustrated in Figs. 1 and 2 wherein similar 5 structural elements are indicated with prime reference numerals.
• the spacer element 16' is substantially shaped in cross-section in the form of the letter "Z", the upper portion is shaped to maintain mechanical contact with the peripheral edge of sheet 12'

• the isocyanate from the bulk storage tank 54 is delivered to a conditioning tank 58, while the polyol blend is delivered to a tank 60.
• the outlets of the tanks 58 and 60 communicate with respective displacement cylinders or high pressure metering pumps 66 and 68 through respective recirculation pumps 62 and 64 to keep the material flowing at all times through the supply lines leading to a mixing head 74 and through recircula ion lines to heat exchangers 70 and 72 and thence to the conditioning tanks 58 and 60.
• Heat exchangers 70 and 72 are employed in the system to maintain the desired reactant temper tures. Constant motion and temperature control are essential to keep various insoluble compounds which may be present in suspension, at temperatures at which the reactants remain inert and liquid, but at which they will react rapidly when brought together.
