  • an exemplary window assembly 10 is provided that includes an insulated glass unit and in particular a vacuum insulated glass (VIG) unit 12 and a frame assembly 14.
  • the window assembly 10 can be installed in a wall 16 ( Figure 1 ) of a building or home, for example.
  • the VIG unit 12 may include first and second glass substrates 18, 20 that cooperate to define a space 22 therebetween.
  • the space 22 may be at a pressure that is less than atmospheric pressure.
  • the second glass substrate 20 is the interior substrate (i.e., the substrate that is exposed to the interior of the building or home) and includes a vacuum port or tube 24 (shown schematically in Figures 2 and 3) defining a passage 25 that is in communication with the space 22. Gas within the space 22 can be evacuated through the vacuum port 24 prior to or after installation of the VIG unit 12 in the frame assembly 14.
  • the frame assembly 14 may include a head portion 26, a sill portion 28 and a pair of jamb portions 30.
  • the head, sill and jamb portions 26, 28, 30 may cooperate to support the VIG unit 12.
  • the head, sill and jamb portions 26, 28, 30 may be wood, vinyl, aluminum or any suitable structural material having a desirable thermal conductivity.
  • the head, sill and jamb portions 26, 28, 30 may include certain additives that lower thermal conductivity.
  • the material can include embedded microspheres. Embedded microspheres may include, for example, expanding microspheres.
  • the head, sill and jamb portions 26, 28, 30 may be generally similar or identical, and therefore, only the sill portion 28 will be described in detail below.
  • the sill portion 28 may include a base member 32 and a glazing member 34.
  • the glazing member 34 may be disposed on the interior side of the VIG unit 12 (i.e., the glazing member 34 may be disposed in the interior of the building or home) and may engage the base member 32 to define a slot 36 therebetween that receives some or all of an edge portion 37 of the VIG unit 12.
  • the edge portion 37 is defined as extending approximately 2.5 inches from a distal edge 33 of the VIG unit 12.
  • a gasket 35 may be provided between the VIG unit 12 and the base member 32 and/or between the VIG unit 12 and the glazing member 34 to restrict or prevent fluid from entering the slot 36.
  • the edge portion 37 of the VIG unit 12 may extend into the slot 36 to a bite depth D of greater than or equal to 1 .25 inches.
  • the bite depth D could be between about 0.75 and 5 inches or between about 0.75 and 3 inches, for example.
  • the VIG unit 12 tends to have higher thermal conductivity at the distal edge 33 due to the edge seal between the first and second glass substrates 18, 20 at the distal edge 33. Therefore, the large bite depth lengthens the path that thermal energy (heat or cold) must travel to conduct between interior and exterior sides of the VIG unit 12, thereby improving the thermal performance of the window assembly 10.
  • the surface temperatures of the first and second glass substrates 18, 20 remain relatively constant from the center of the glass substrates 18, 20 until reaching the edge portion 37, i.e., approximately 2.5 inches from the distal edge 33, whereat the surface temperatures transition along a steep temperature gradient to the distal edge 33, which is unique to high performing VIG units.
  • the surface temperature of the first glass substrate 18 transitions towards the surface temperature of the second glass substrate 20 while the surface temperature of the second glass substrate 20 transitions towards the surface temperature of the first glass substrate 18.
  • the large bite depth prevents the accumulation of condensation on the second glass substrate 20 by affecting the surface temperature of the second glass substrate 20 that is exposed to the environmental conditions (e.g., relative humidity) of the interior of the building or home.
  • the environmental conditions e.g., relative humidity
  • the distal edge 33 of the VIG unit 12 is seated on one or more glazing blocks 47 at the bottom of the slot 36.
  • the glazing blocks 47 may comprise a rubber or similar polymer material and are used to support the VIG unit 12 during assembly of the window assembly 10.
  • the glazing blocks 47 may be spaced apart to allow moisture that enters the slot 36 to drain out through weeping holes (not shown) in the bottom of the slot 36.
  • the base member 32 may be extruded, pultruded or injection molded from a polymeric or composite material, for example, and may include a plurality of support members or ribs 39 that cooperate to form one or more pockets 38.
  • the pockets 38 may serve to reduce or hinder thermal conductivity through the base member 32.
  • a lower end of the base member 32 may include one or more tabs 41 that engage the wall 16 of the building or home.
  • One or more of the pockets 38 may be filled with air 42 and/or other gasses and one or more of the pockets 38 may be filled with an insulation material 44 to reduce the thermal conductivity of the frame assembly 14.
  • the insulation material 44 can include foam, rubber, glass microspheres, perlite, aerogel, fused silica, and/or inert-gas-filled foam, for example. It will be appreciated that in some variations, all of the pockets 38 could be filled with air and/or other gases, or all of the pockets 38 could be filled with the insulation material 44. Any combination of such insulating gases or materials may be employed in the same or different pockets 38.
  • one or more of the ribs 39 may include reinforcement members 46 to provide additional rigidity and strength to the frame assembly 14 to reinforce the frame assembly 14 against forces caused by distortion of the VIG unit 12, for example.
  • the reinforcement members 46 can be formed from any suitable material and can be embedded, co-extruded, co-pultruded or incorporated into the frame assembly 14 in any suitable manner.
  • the reinforcement members 46 may have any suitable cross-section such as circular, rectangular, or square.
  • a first lateral surface 49 of the base member 32 may contact the first glass substrate 18 and cooperates with the glazing member 34 to securely retain the VIG unit 12 in the frame assembly 14.
  • a two-sided adhesive glazing tape 51 or silicone or silicone-like product is disposed between the first lateral surface 49 and the first glass substrate 18.
  • the base member 32 may include a recess 48 adjacent the slot 36. As shown in Figure 3, the recess 48 is designed to accommodate distortion of the VIG unit 12 rather than constraining the VIG unit 12 at the distal edge 33. Constraining at the distal edge 33 may introduce significant additional stresses into the VIG unit 12.
  • the base member 32 and the glazing member 34 may be designed to constrain the VIG unit 12 adjacent the sight line S, thereby preventing or minimizing distortion of the VIG unit 12. Constraining the VIG unit 12 adjacent the sight line S introduces less stress into the VIG unit 12 than would be introduced if the VIG unit 12 is constrained at the distal edge 33.
  • the glazing member 34 may be designed to flex or pivot towards the interior of the building or home in response to distortion of the VIG unit 12.
  • a primary cause of distortion of the VIG unit 12 is differences in thermal expansion and contraction as a result of exposure to large differences between outdoor and indoor temperatures which due to the rigid edge seal of the VIG unit 12 causes the first and second glass substrates 18, 20 to distort together in the same direction.
  • thermal distortion of the first and second substrates 18, 20 together tends to be an issue that arises for VIG units, but not for conventional IG or other window units.
  • the ability for the edge portion 37 of the VIG unit 12 to experience thermal distortion into the recess 48 prevents potential mechanical stress or failure of the VIG unit 12 or frame assembly 14 over long-term use.
  • a thermally insulative barrier 50 may be located in the recess 48.
  • An adhesive may bond the insulative barrier 50 to the VIG unit 12 and/or to the base member 32.
  • the insulative barrier 50 could include silicone or a polystyrene tape.
  • the insulative barrier 50 could be approximately five millimeters thick or thicker.
  • the insulative barrier 50 may structurally adhere the base member 32 to the VIG unit 12 and absorb and displace energy associated with the distortion of the VIG unit 12.
  • the recess 48 could be open (e.g., filled with gas or air rather than the insulative barrier 50).
  • one or more of the ribs 39 of the base member 32 may be trimmed or removed so that one or more of the pockets 38 may define another slot for receiving other glass substrate(s) or a second VIG unit.
  • first and second ribs 52, 54 may be trimmed or removed so that first and second pockets 56, 58 can function as a slot for receiving another glass substrate 13 (as shown in Figure 6) or a second VIG unit 15 (as shown in Figure 7).
  • first and second ribs 52, 54 may include one or more notches 60 that facilitate the cutting or breaking of the first and second ribs 52, 54 to allow for the insertion of glass substrate 13 or the second VIG unit 15 as well as insulation material (e.g., foam, rubber, glass microspheres, perlite, aerogel, fused silica, and/or inert-gas-filled foam) to surround the glass substrate 13 or the second VIG unit 15.
  • insulation material e.g., foam, rubber, glass microspheres, perlite, aerogel, fused silica, and/or inert-gas-filled foam
  • the glazing member 34 may comprise a polymeric material or a polymeric composite comprising a reinforcement phase.
  • the glazing member 34 may be formed via extruding, pultruding or injection molding such a polymeric or composite material, for example, and may include a plurality of support members or ribs 62 that cooperate to form pockets 64.
  • One or more of the pockets 64 may be filled with air, other gases and/or insulation material 66 to reduce the thermal conductivity of the frame assembly 14.
  • the insulation material 66 can include foam, rubber, glass microspheres, perlite, aerogel, fused silica, and/or inert-gas-filled foam, for example.
  • one or more of the ribs 62 may include reinforcement members 46 to provide additional rigidity and strength to the frame assembly 14.
  • First and second lateral surfaces 68, 70 of the glazing member 34 may contact the second glass substrate 20 and cooperate with the base member 32 to securely retain the VIG unit 12 in the frame assembly 14.
  • two-sided adhesive glazing tape 51 or silicone or silicone-like product is disposed between the first and/or second lateral surfaces 68, 70 and the second glass substrate 20.
  • a lower end of the glazing member 34 may include one or more resiliently flexible tabs 72 that snap into engagement with the base member 32.
  • the tabs 72 may allow the glazing member 34 to pivot to accommodate distortion of the VIG unit 12 and/or provide for removal of the glazing member 34. In this manner, the glazing member 34 may be repeatedly snapped into and out of the window assembly 10 on demand, even after the window assembly 10 has been installed into the wall 16 of the building or home.
  • the glazing member 34 may also include a recess (or cavity) 74 formed between the first and second lateral surfaces 68, 70. The recess 74 may receive the vacuum port 24 of the VIG unit 12 and may protect the vacuum port 24 from being damaged.
  • the recess 74 is designed to accommodate distortion of the VIG unit 12 without damaging the vacuum port 24, or more importantly, without causing the VIG unit 12 to lose its vacuum.
  • the recess 74 may be filled with an insulative material 76 that surrounds the vacuum port 24.
  • the insulative material 76 can include foam, rubber, glass microspheres, perlite, aerogel, fused silica, and/or inert-gas-filled foam, for example.
  • the insulative material 76 may be compliant enough to allow for relative movement between the vacuum port 24 and the glazing member 34 without damaging the vacuum port 24, or more importantly, without causing the VIG unit 12 to lose its vacuum.
  • the second lateral surface 70 of the glazing member 34 does not contact the second glass substrate 20.
  • the recess 74 extends from the first lateral surface 68 to the bottom of the slot 36.
  • another recess or cavity 75 (similar to the recess 74) may be formed in the base member 32 that may receive a vacuum port 25 of the second VIG unit 15. While the figures show the VIG units 12, 15 having outwardly protruding vacuum ports 24, 25, in some configurations, the vacuum ports 24, 25 may be substantially flush to the surface of the glass substrate of the VIG unit 12, 15. In other configurations, the VIG units 12, 15 may not include the vacuum ports 24, 25 at all.
  • first and second glass substrates 18, 20 of either or both of the VIG units 12, 15 could be laminated substrates (e.g., substrates with laminated layers of glass with a layer of polyvinyl butyral (PVB) between the glass layers).
  • PVB polyvinyl butyral
  • the glazing member 34 may be disposed on the exterior side of the VIG unit 12 (i.e., the glazing member 34 may be disposed on the exterior of the building or home) to accommodate distortion of the VIG unit 12 in a direction opposite to what would be experienced in colder climates (such as the northern United States).
  • a coupler 80 is provided that may be used to adapt the VIG unit 12 to a standard window frame assembly 82.
  • the coupler 80 may include features similar or identical to the frame assembly 14, such as the recess 48 and the recess 74 to accommodate distortion of the VIG unit 12.
  • the coupler 80 provides a large bite depth to hinder heat transfer between the first and second substrates 18, 20 and prevent the accumulation of condensation on the second glass substrate 20.
  • the coupler 80 may be received in or otherwise attached to the frame assembly 82.

Abstract

L'invention concerne un ensemble fenêtre qui comprend une unité de vitrage isolant sous vide et un ensemble châssis. L'unité de vitrage isolant sous vide comprend des premier et second substrats de verre, qui définissent entre eux un espace dont la pression est inférieure à la pression atmosphérique. Le premier ou le second substrat de verre comporte un orifice d'aspiration s'étendant vers l'extérieur à partir de celui-ci. L'orifice d'aspiration définit un passage en communication avec l'espace. L'ensemble châssis soutient l'unité de vitrage et comprend un élément de base et un élément vitre. L'élément de base et l'élément vitre coopèrent de manière à définir une fente dans laquelle une partie de bord de l'unité de vitrage est reçue. L'élément vitre comprend une cavité qui reçoit l'orifice d'aspiration.
