Description

Technology Field

[0001] This application claims priority to U.S. Provisional Application No. 62 / 783,787 under 35 USC § 119, the entirety of which is incorporated herein by reference.

[0002] This document generally relates to fenestration assemblies and panes for fenestration assemblies, but is not limited to them. Background Technology

[0003] A window assembly (e.g., door, window, etc.) is combined with a structure (e.g., single-family house, townhome, warehouse, office building, etc.). In some embodiments, the window assembly comprises one or more glass panes (e.g., sheets of soda-lime glass), and the glass panes allow light to enter the structure while preventing elements (e.g., wind, rain, dust, foreign matter, etc.) from entering the structure. Additionally, the window assembly limits heat transfer from the structure to the surrounding environment.

[0004] Generally, the present disclosure relates to various embodiments of window assemblies having customized structures for improved performance characteristics of one or both of acoustic performance (e.g., noise reduction) and / or reduced edge seal force (e.g., where, not limited to specific mechanisms and / or theories, the edge seal force is considered a proxy metric attributable to the window assembly life (e.g., performance, operational capability, and / or durability)).

[0005] More specifically, the present disclosure relates to an intrinsic and / or custom structure of a window assembly (e.g., triple glass with double chambers forming an IGU and corresponding seals), wherein: (1) the outer glass (first glass) is configured in a higher proportion to the total IGU thickness (e.g., or weight) for improved acoustic performance of the window assembly and / or (2) the remaining two glass panes (e.g., second glass and third glass) are configured so as not to be greater than 1.2 N / m across the IGU for improved edge sealing of the window assembly and thus promotes improved performance and / or corresponding improved life of the IGU (e.g., compared to a triple glass IGU without (1) and / or (2)). One or more embodiments described in detail herein are clearly designed and / or configured to maximize noise reduction and / or prevent, relieve, and / or reduce stress on edge seals (e.g., edge sealing force). The problem to be solved

[0006] The inventors have recognized, among other things, that the problem to be solved may include improving the performance of a window assembly (e.g., door, window, etc.). Additionally, the inventors have recognized, among other things, that the problem to be solved may include reducing the amount of noise entering a structure through the window assembly (e.g., noise generated by a vehicle passing through the structure, noise generated by a neighboring structure, etc.). Furthermore, the inventors have recognized, among other things, that the problem to be solved may include improving the thermal insulation performance of the window assembly. Furthermore, the inventors have recognized, among other things, that the problem to be solved may include providing a triple-pane window assembly having similar dimensions (e.g., thickness) and / or weight to a double-pane window assembly. Furthermore, the inventors have recognized, that the problem to be solved may include providing a triple-pane window assembly having smaller dimensions (e.g., thickness) and / or smaller weight than a double-pane window assembly. Additionally, the inventors have recognized that the problem to be solved may include improving the mechanical performance (e.g., impact recovery or static load recovery) or life performance (e.g., service life, technical life, expected life, etc.) of a window assembly. means of solving the problem

[0007] The subject matter may help provide a solution to these problems, for example, by providing a triple-pane glass window assembly. A triple-pane glass window assembly provides improved performance (e.g., thermal insulation) compared to a double-pane or single-pane glass window assembly. In some embodiments, a triple-pane glass window assembly may include a first glass plate spaced apart from a second glass plate, and a third glass plate spaced apart from the second glass plate. The second glass plate may be located between the first glass plate and the third glass plate. The second glass plate may be located between the first glass plate and the third glass plate while being spaced apart from the first glass plate and the third glass plate (e.g., the second glass plate is centered between the first glass plate and the third glass plate). The first glass plate has a first glass plate thickness, the second glass plate has a second glass plate thickness, and the third glass plate has a third glass plate thickness.

[0008] In the embodiment, the first glass plate, the second glass plate, and the third glass plate may comprise soda-lime glass. The thickness of the first glass plate and the thickness of the third glass plate may be approximately 6 mm, and the thickness of the third glass plate may be approximately 3 mm. The first chamber gap is 12 mm and may be located between the first glass plate and the second glass plate. The second chamber gap is 12 mm and may be located between the second glass plate and the third glass plate. Accordingly, the distance from the exposed surfaces of the first glass plate and the second glass plate may be approximately 39 mm.

[0009] In another embodiment, the thickness of the second glass plate may be 1 mm or less, and the thicknesses of the first glass plate and the third glass plate may be approximately 6 mm. In this embodiment, since the thickness of the second glass plate is 1 mm or less, the overall dimensions (e.g., thickness) or weight of the triple glass window assembly may be reduced (e.g., compared to the third glass plate being approximately 3 mm). For example, the distance from the exposed surfaces of the first glass plate and the third glass plate may be approximately 37 mm. Thus, reducing the thickness of the second glass plate correspondingly reduces the weight of the triple glass window assembly.

[0010] In some embodiments, the second plate glass comprises soda-lime glass. However, soda-lime glass is not commercially available in sufficient size, quantity, and cost for window assemblies with a thickness of 1 mm or less (e.g., a 3-foot x 6-foot window, a 4-foot x 8-foot sliding glass door, etc.). Therefore, window assemblies comprising plate glass with soda-lime glass having a thickness of 1 mm or less are not commercially suitable.

[0011] However, in some embodiments, the second glass pane may comprise a glazing material with a low coefficient of thermal expansion ("low CTE") (e.g., alumina borosilicate, etc.). The low CTE glazing material may be manufactured with a thickness of 1 mm or less for the window assembly, and in commercially suitable sizes, quantities, and costs. Thus, the low CTE glazing provides a commercially suitable triple glass window assembly compared to a triple glass window assembly that does not include low CTE glazing (e.g., each of the first glass pane, the second glass pane, and the third glass pane comprises soda-lime glass).

[0012] In another embodiment, the second plate glass comprises a glazing material having low surface compression. In one embodiment, the glazing material has a surface compression in the range of 0 MPa to 52 MPa. In another embodiment, the glazing material has a surface compression in the range of 20 MPa to 30 MPa. In yet another embodiment, the glazing material has a surface compression of 24 MPa or less. The glazing material can be manufactured with a thickness of 1 mm or less, in a commercially suitable size, quantity, and cost for a window assembly. Thus, the glazing material provides a commercially suitable triple plate glass window assembly.

[0013] A triple-pane window assembly reduces the amount of noise transmitted into a structure through the window assembly. Arranging the thicker panes of glass in the window assembly (e.g., the first pane) away from the interior of the structure improves the acoustic performance of the triple-pane window assembly. In one embodiment, the first pane is arranged away from the interior of the structure (e.g., the first pane is exposed to the environment surrounding the structure). The thickness of the first pane may be greater than the thickness of the second pane and the thickness of the third pane. Thus, the mass of the glass in the window assembly is shifted toward the exterior of the structure (e.g., the thicker pane is arranged toward the exterior of the structure). As described in detail herein, the shift in the mass of the glass in the window assembly reduces the transmission of noise from the exterior of the structure to the interior of the structure.

[0014] Additionally, since the thickness of the third glass plate may be 1 mm or less, the mechanical performance of the triple glass window assembly may be improved. In one embodiment, the distance from the exposed surfaces of the first glass plate (e.g., outer glass plate) and the third glass plate (e.g., inner glass plate) may be maintained constant. In this embodiment, since the thickness of the second glass plate (e.g., center glass plate) may be reduced, the thickness of the first glass plate or the thickness of the third glass plate may be increased while maintaining the same distance from the exposed surfaces of the first glass plate and the third glass plate. An increase in the first thickness or the third thickness may improve the resistance of the first glass plate or the third glass plate to impact (e.g., hail impact, rock impact, etc.).

[0015] In addition, since the second thickness can be reduced, the stress applied to the seal due to pressure changes in the first chamber gap or the second chamber gap can be correspondingly reduced, thereby improving the lifespan of the window assembly. In addition, one or more glass panes of the third glass window assembly may include a plurality of glass pane layers (e.g., the first glass pane may include a laminate structure). The plurality of layers can improve the impact resistance of the glass panes.

FIG. 10 illustrates one embodiment of a method for manufacturing a window assembly according to various embodiments of the present disclosure. Specific details for implementing the invention

[0018] FIG. 1 illustrates a schematic example of a first window assembly (100) (e.g., window, door, etc.). The window assembly (100) may include a window frame (110, frame) and a sash (120, sash). The window frame (110) is configured for installation within a structure including (but not limited to) a single-family house, a multi-family house, an urban structure, a warehouse, an office building, etc. In some embodiments, the window assembly (100) includes one or more glass panes (130) (e.g., a sheet of soda-lime glass), and the glass panes (130) allow light to enter the structure while preventing elements (e.g., wind, rain, dust, foreign matter, etc.) from entering the structure. The glass panes (130) may include at least one of surface features or subsurface features. In one embodiment, one or more glass panes (130) may be frosted. In another embodiment, one or more glass plates (130) include an uneven surface that distorts light passing through the glass plates (130).

[0019] One or more glass panes (130) may be combined with a chassis (120) (e.g., installed inside). The chassis (120) may be combined along the periphery of one or more glass panes (130). The chassis (120) may be movably combined with a frame (110). For example, the chassis (120) may move between a closed position and an open position relative to the window frame (110). In one embodiment, the chassis (120) slides relative to the frame (110). In another embodiment, the chassis (120) rotates relative to the frame (110) (e.g., opens outward from the frame (110)).

[0020] FIG. 2 shows a cross-sectional view of the first window assembly (100) of FIG. 1. As described herein, the window assembly (100) includes one or more glass panes (130), and one or more glass panes may be combined with a sash (120). For example, the window assembly (100) may include a first glass pane (130A), a second glass pane (130B), and a third glass pane (130C). In this embodiment, the window assembly (100) is a triple glass window assembly. A triple glass window assembly can provide improved performance (e.g., solar heat gain coefficient, insulation, etc.) compared to a double glass window assembly (e.g., a window assembly having two glass panes).

[0021] The window assembly (100) may include one or more chamber gaps (200) and one or more spacers (210). For example, a first glass plate (130A) may be spaced apart from a second glass plate (130B) by the first chamber gap (200A) (e.g., within a range of approximately 1-20 mm, e.g., 12 mm). In one embodiment, the second glass plate (130B) is centered between the first glass plate (130A) and the third glass plate (130C). A first spacer (210A) may be located within the first chamber gap (200A), and a second spacer (210B) may be located within the second chamber gap (200B). The spacers (210) may provide a seal for the chamber gap (200). For example, a spacer (210) and a glass plate (130) can cooperate to provide a chamber gap (200), and the chamber gap (200) can be sealed from the surrounding environment. Additionally, the spacer (210) can be positioned between the glass plate (130) and the window frame (110). The chamber gap (200) may contain an insulating gas (e.g., an inert gas, e.g., nitrogen, argon, krypton, etc.) or a vacuum (e.g., a partial vacuum).

[0022] In some embodiments, the first plate glass (130A), the second plate glass (130B), and / or the third plate glass (130C) comprises a plurality of layers (230). The plurality of layers may be combined together (e.g., laminated, etc.) to provide one or more plate glass (130) (e.g., the third plate glass (130C)). As shown in FIG. 2, the third plate glass (130C) may comprise a glass layer (230A), an intermediate layer (230B), and a glazing layer (230C). The intermediate layer (230B) may be positioned between the glass layer (230A) and the glazing layer (230C) (e.g., sandwiched, etc.). The glass layer (230A) may comprise a soda-lime glass material. The intermediate layer (220B) may comprise a polymer material (e.g., polyvinyl butyral, ethylene-vinyl acetate, thermoplastic urethane, ionomers, etc., or a combination thereof). In one embodiment, the glazing layer (230C) may comprise a glazing material with a low coefficient of thermal expansion ("low CTE") (e.g., alumina borosilicate). For example, the coefficient of thermal expansion of the glazing layer (230C) is approximately 97 x 10⁻⁶. -7 It may be less than / K. In another embodiment, the CTE of the glazing layer (230C) is 70 x 10 -7 / K or less. In another embodiment, the glazing layer (220C) may have a surface compression within the range of 500 MPa to 700 MPa (e.g., 575 MPa to 625 MPa, 625 MPa to 640 MPa, etc.). In yet another embodiment, the glazing layer (220C) may have a surface compression greater than 600 MPa (e.g., 750 MPa).

[0023] The glass layer (230A) has a glass layer thickness (240A), the intermediate layer (230B) has an intermediate layer thickness (240B), and the glazing layer (230C) has a glazing layer thickness (240C). The glazing layer thickness (240C) may be smaller than the glass layer thickness (240A). For example, the glass layer thickness (240A) may be in the range of approximately 2 mm to 6 mm (e.g., 3 mm to 4 mm, 4 mm to 5 mm, etc.). The glazing layer thickness (240C) may be 1 mm or less (e.g., 0.5 mm, 0.7 mm, 0.6 mm to 0.8 mm, etc.). The intermediate layer thickness (240B) may be in the range of approximately 0.3 mm to 3 mm. In one embodiment, the glass layer thickness (240A) may be 3 mm and the glazing layer thickness (240C) may be 0.55 mm. In another embodiment, the glass layer thickness (240A) may be 5 mm and the glazing layer thickness (240C) may be 0.7 mm.

[0024] As described in more detail herein, the layer (220) can improve the mechanical performance of the plate glass (130). For example, the layer (230A, 230B, 230C), when incorporated into the first plate glass (130) (not shown), may have improved impact performance and can withstand a greater amount of energy compared to a single configuration (e.g., the first plate glass (130A) may comprise a single layer or a single portion of soda-lime glass). In one embodiment, the thickness of the first layer (240A) may be increased, and the increase in the thickness of the first layer (240A) may improve the resistance of the first or second plate glass to impact (e.g., hail impact, rock impact, etc.). Additionally, the intermediate layer (230B) may dissipate the force applied to the plate glass (130) and thus increase the impact resistance of the plate glass (130).

[0025] Referring again to FIG. 2, the first plate glass (130A) includes a first plate glass thickness (220A), the second plate glass (130B) includes a second plate glass thickness (220B), and the third plate glass (130C) includes a third plate glass thickness (220C). The second plate glass thickness (220B) may be smaller than the first plate glass thickness (220A) or the third plate glass thickness (230C). In one embodiment, the second plate glass thickness (220B) may be 2 mm or less, the first plate glass thickness (220A) may be within the range of approximately 3 mm to 12 mm, and the third plate glass thickness (220C) may be within the range of 2 mm to 12 mm. In another embodiment, the second glass plate thickness (220B) may be 1 mm or less, the first glass plate thickness (220A) may be within the range of approximately 3 mm to 6 mm, and the third glass plate thickness (220C) may be within the range of 3 mm to 10 mm.

[0026] In some embodiments, the first plate glass (130A) and the third plate glass (130C) comprise soda-lime glass. However, soda-lime glass is not commercially available in suitable sizes, quantities, and costs for window assemblies with a thickness of 1 mm or less (e.g., 3-foot x 6-foot windows, 4-foot x 8-foot glass doors, etc.). Therefore, window assemblies comprising plate glass with soda-lime glass with a thickness of 1 mm or less are not commercially suitable.

[0027] The second plate glass (130B) may include a low CTE glazing material, or the second plate glass (130B) may have low surface compression. The low CTE glazing material, or the glazing material with low surface compression, may be manufactured with a thickness of 1 mm or less, and in a commercially suitable size, quantity, and cost for a window assembly (e.g., window assembly (100)). Thus, the low CTE glazing provides a commercially suitable window assembly (e.g., window assembly (100)) compared to a window assembly that does not include the low CTE glazing or the glazing material with low surface compression.

[0028] FIG. 3 shows a graph of the acoustic performance of a window assembly (e.g., the window assembly (100) shown in FIG. 1). The Y-axis of FIG. 3 represents the Outdoor / Indoor Transmission Class ("OITC") of the window assembly, as described in, for example, ASTM standard E1332. A higher OITC rating indicates improved sound attenuation of the window assembly (e.g., reduced noise transmission through it).

[0029] The X-axis of FIG. 3 represents the weight of the outer glass plate of the window assembly (e.g., the first glass plate (130B), or the outermost glass plate of the window assembly (100) relative to the interior of the structure). The area of ​​the outer glass plate (e.g., the height and width of the outer glass plate) is kept constant, and the thickness of the outer glass plate varies to correspond to the weight of the outer glass plate. In one embodiment, the outer glass plate is approximately 21 kg / m² 2 It may have a weight of and a calculated OITC rating greater than about 22.15. In another embodiment, the outer glass plate is about 26 kg / m² 2 It can have a weight and an OITC rating greater than about 22.35.

[0030] The circular data points in Fig. 3 represent a window assembly containing only soda-lime glass and thus not including plate glass with a thickness of 1 mm or less. The diamond-shaped data points represent a window assembly containing plate glass with a thickness of 1 mm or less. As shown in Fig. 3, as the thickness of the outer plate glass increases, the sound attenuation increases correspondingly. Furthermore, a window assembly containing one or more plate glasses with a thickness of 1 mm or less provides increased sound attenuation compared to a window assembly not containing one or more plate glasses with a thickness of 1 mm or less (e.g., a window assembly containing only soda-lime glass).

[0031] Providing a window assembly in which the thickness of the glass plate (e.g., second glass plate thickness (230B)) is 1 mm or less (e.g., window assembly (100)) facilitates shifting the thicker glass plate within the window assembly toward the portion facing the outside of the window assembly. Accordingly, a window assembly comprising one or more glass plates having a thickness of 1 mm or less improves the acoustic performance of the window assembly (e.g., window assembly (100)).

[0032] FIG. 4 shows another graph of the acoustic performance of a window assembly (e.g., the window assembly (100) illustrated in FIG. 1). The Y-axis of FIG. 4 represents the calculated weighted sound reduction index (R) of the window assembly. W It is. Larger R WThis represents, for example, the improved sound attenuation of the window assembly (e.g., reduced sound transmission therethrough) according to ISO standard 717-1. The X-axis of FIG. 4 is the weight of the outer glass panes of the window assembly (e.g., the first glass pane (130B), or the outermost glass pane of the window assembly (100) relative to the interior of the structure). The area of ​​the outer glass panes (e.g., the height and width of the outer glass panes) is kept constant, and the thickness of the outer glass panes is varied to correspondingly change the weight of the outer glass panes. In some embodiments, the total area weight of the glass panes (130) within the window assembly (e.g., window assembly (100)) (e.g., weight of glass panes per unit area) is approximately 18 kg / m² 2 Up to 32 kg / m² 2 It is within the range. In one embodiment, the total area weight is approximately 18 kg / m² 2 Up to 23 kg / m² 2 It is within the range. In another embodiment, the total area weight is approximately 23 kg / m² 2 Up to 28 kg / m² 2 It is within the range of.

[0033] The circular data points in Fig. 4 represent a window assembly containing only soda-lime glass and thus not including plate glass with a thickness of 1 mm or less. The diamond-shaped data points represent a window assembly containing plate glass with a thickness of 1 mm or less. As shown in Fig. 4, as the thickness of the outer plate glass increases, the sound attenuation increases correspondingly. Furthermore, a window assembly containing one or more plate glasses with a thickness of 1 mm or less provides reduced sound attenuation compared to a window assembly not containing one or more plate glasses with a thickness of 1 mm or less (e.g., a window assembly containing only soda-lime glass).

[0034] FIG. 5 shows a graph of force at the edge seal (210) of various window assemblies (e.g., the window assembly (100) shown in FIG. 1). To calculate the edge seal force, the European Standard prEN 16612 (August 2017) draft, “Glass in Building - Determination of the lateral load resistance of glass panes by calculation” was utilized. Since the European Standard prEN 16612 provides a method for determining the lateral load resistance of linearly supported glass elements, it was utilized to quantify the edge seal force for the triple-pane glass IGU of the described window assembly to provide a comparison standard.

[0035] As described herein, the window assembly (100) may include a seal between the glass panes (130). The seal may trap an insulating gas (e.g., an inert gas) within the chamber gap (200) or maintain a partial vacuum. Temperature and pressure fluctuations in the environment may cause changes in pressure within the chamber gap. This ultimately applies mechanical stress to the edge seal, which may affect the ability of the main seal to function. Since the lifespan of the window assembly may be limited by the duration the chamber gap (200) remains sealed, a low edge seal is desirable.

[0036] The Y-axis of FIG. 5 represents the calculated edge sealing force resulting from variations in chamber gap pressure for different window assemblies (e.g., force applied by the spacer (210) shown in FIG. 2). Square data points represent a typical window assembly containing conventional soda-lime glass sheets with a thickness of 3 mm or more, and thus not containing glass sheets with a thickness of 1 mm or less. Square data points provide an edge sealing force of approximately 0.55 N / m to 0.57 N / m. Circular data points represent a window assembly containing one or more glass sheets with a thickness of 1 mm or less (e.g., window assembly (100) shown in FIG. 1). Circular data points provide an edge sealing force of 0.8 N / m to 0.4 N / m for the window assembly quantified in FIG. 5.

[0037] As shown in Fig. 5, the edge sealing force is smaller for a window assembly containing one or more glass panes with a thickness of 1 mm or less. Therefore, the lifespan is expected to be greater for a window assembly containing one or more glass panes with a thickness of 1 mm or less. Conversely, a window assembly containing only thicker glass has a greater edge sealing force and a correspondingly lower expected lifespan. Additionally, when the glass panes contain a low CTE glazing material, the thermal expansion and contraction of the low CTE glazing material are reduced, and thus the stress and strain applied to the seal around the low CTE glazing material are correspondingly reduced. Therefore, the expected lifespan of the window assembly is improved.

[0038] FIG. 6 shows a graph of the total glass thickness of a window assembly versus the percentage of the total glass thickness of the first glass plate of the window assembly (e.g., the window assembly (100) shown in FIG. 1). The X-axis of FIG. 6 is the total glass thickness of the window assembly. Total glass thickness (t Total) is calculated by adding the glass thickness of the first glass plate (t1, e.g., 220A in FIG. 2), the glass thickness of the second glass plate (t2, e.g., 220B in FIG. 2), and the glass thickness of the third glass plate (t3, e.g., 220C for a single glass plate in FIG. 2, or 240A+240C for a laminate). The Y-axis of FIG. 6 is the percentage of the total glass thickness in the first glass plate. The percentage of the total glass thickness in the first glass plate can be calculated by the following:

[0039] t1 / t Total * 100

[0040] The circular data points in FIG. 6 represent a conventional triple-pane window assembly comprising only soda-lime glass and, therefore, not including plate glass with a thickness of less than 2 mm. The diamond-shaped data points represent a window assembly comprising plate glass with a thickness of less than 2 mm (e.g., as a second plate glass and / or a third plate glass). As shown in FIG. 6, the line separating the present triple-pane window assembly (represented by the diamond-shaped data points) from the conventional triple-pane window assembly (represented by the circular data points) is represented as follows:

[0041]

[0042] A window assembly comprising one or more glass plates with a thickness of less than 2 mm (e.g., a second glass plate or a third glass plate) (e.g., represented by diamond-shaped data points) provides increased sound attenuation compared to a window assembly that does not include one or more glass plates with a thickness of less than 2 mm (e.g., a window assembly comprising only soda-lime glass, such as represented by circular point data).

[0043] Providing a window assembly (e.g., window assembly (100)) in which the thickness of the glass plate (e.g., the second glass plate thickness (220B) of FIG. 2) is less than 2 mm facilitates shifting the thick glass plate within the window assembly toward the portion facing the outside of the window assembly (e.g., the outer glass plate, also indicated as the first glass plate in the specification). Thus, a window assembly comprising one or more glass plates having a thickness less than 2 mm improves the acoustic performance of the window assembly (e.g., window assembly (100)).

[0044] As shown in FIG. 6, the diamond-shaped data point does not exceed about 16 mm of the total glass thickness, and the corresponding percentage of plate glass (1) of the total glass thickness is 43% to 80% of the total glass thickness. Through the first plate glass of 43-80% of the total glass thickness, the remaining second and third plate glass thicknesses together are not greater than 20% and not greater than 15% of the total glass thickness. Compared to the circular data point, only a few are less than 16 mm of the total glass thickness, and some data points have a percentage of plate glass (1) of the total glass thickness that is much smaller than the circular data point, approximately 30% to 45%. Through the first plate glass of 35% to 45%, the remaining second and third plate glass thicknesses together are 45% or less and 70% or less. For a triple-pane glass window assembly with a total glass thickness not exceeding 16 mm, the circular data point has a second glass and third glass thickness greater than the square data point.

[0045] In one or more embodiments of the present disclosure, the total glass thickness of the triple glass IGU comprises: a first glass plate of 90% or less of the total glass thickness; and a glass thickness of 10% or less of the total glass thickness together with the second glass plate and the third glass plate.

[0046] In one or more embodiments of the present disclosure, the total glass thickness of the triple glass IGU comprises: a first glass plate of 80% or less of the total glass thickness; and a glass thickness of 20% or less of the total glass thickness together with the second glass plate and the third glass plate.

[0052] FIG. 7 shows a ternary diagram of the glass percentage (by weight) of each of the three panes of glass in a window assembly (e.g., the window assembly (100) shown in FIG. 1). The weight percentages are provided in fractional form (e.g., 0.1 corresponds to 10% of the total glass weight of the triple pane window assembly). The X-axis (bottom axis) of FIG. 7 is the percentage of the total glass weight within the first pane of glass and can be calculated by the following:

[0053] w1 / w Total

[0054] Here, w Total It is equal to the weight of the first plate glass (w1) plus the weight of the second plate glass (w2) plus the weight of the third plate glass (w3). Although FIG. 7 explains the weight percentage in detail, since thickness and weight are proportional to each other, the corresponding diagram will also show the relationship of the IGU components (e.g., plate glass) with respect to the representative thickness.

[0055] The Y-axis (right axis) of Fig. 7 is the percentage of the total glass weight within the third glass plate and can be calculated by the following:

[0056] w3 / w Total

[0057] The Z-axis (left axis) of Fig. 7 is the percentage of the total glass weight within the second glass plate and can be calculated by the following:

[0058] w2 / w Total

[0059] For example, the indicated point (an open circle where three lines intersect) has 43% of the glass weight of the first glass plate (e.g., the outer glass plate (130A) in FIG. 2), 17% of the second glass plate (e.g., the center glass plate (130B) in FIG. 2), and 40% of the third glass plate (e.g., the inner glass plate (130C) in FIG. 2).

[0060] The circular data point in Fig. 7 represents a conventional triple-pane glass window assembly containing only soda-lime glass and thus not including plate glass with a thickness of less than 2 mm. The diamond-shaped data point represents a window assembly containing plate glass with a thickness of less than 2 mm.

[0061] As described above, the window assembly (100) may include a seal between the glass panes (130). The seal may trap an insulating gas (e.g., an inert gas) within the chamber gap (200) or maintain a partial vacuum. Temperature and pressure fluctuations in the environment will cause changes in pressure within the chamber gap. This will eventually apply mechanical stress to the edge seal, which may affect the ability of the main seal to function. Since the life of the window assembly may be limited to the period during which the chamber gap (200) is sealed, a low edge seal force may be desirable.

[0062] The shaded area in Fig. 7 indicates that the calculated value of the edge seal of the inert gas cavity of the window assembly caused by seasonal temperature cycling exceeds the cutoff value. The cutoff value is an edge seal force greater than 1.2 N / m when measured according to prEN 16612. The edge seal force is small for window assemblies containing one or more glass panes with a thickness of 2 mm or less (e.g., indicated by diamond-shaped data points). Conversely, window assemblies containing only thick glass (e.g., indicated by circular data points) have a larger edge seal force and a correspondingly lower expected life. Additionally, when the glass panes contain a low CTE glazing material, the thermal expansion and contraction of the low CTE glazing material are reduced, and thus the stress and strain applied to the seal around the low CTE glazing material are correspondingly reduced. Therefore, the expected life of the window assembly is improved.

[0063] As shown in FIG. 7, the diamond-shaped data points represent weight percentages of plate glass (1) in the range of approximately 43% (0.43) to 80% (0.8) or less, weight percentages of plate glass (2) in the range of approximately 4% to 18%, and weight percentages of plate glass (3) in the range of approximately 16% to 52%.

[0064] In some embodiments, the triple glass window assembly comprises, based on the total glass weight of the window assembly, a first glass weight percentage of 45% to 80% of the total glass weight of the window assembly, a second glass weight percentage of 3 to 20 wt%, and a third glass weight percentage of 15 to 45 wt.%.

[0065] In one or more embodiments of the present disclosure, the total glass weight of the triple glass IGU comprises: a first glass plate of 90% or less of the total glass weight; and the glass weight of the second glass plate and the third glass plate together being 10% or less of the total glass weight.

[0066] In one or more embodiments of the present disclosure, the solid glass weight of the triple plate glass IGU comprises: a first plate glass of 80% or less of the total glass weight; and the glass weight of the second plate glass and the third plate glass together being 20% ​​or less of the total glass weight.

[0067] In one or more embodiments of the present disclosure, the total glass weight of the triple glass plate IGU comprises: a first glass plate having a weight of at least 43% to 80% or less of the total glass weight; a second glass plate having a weight of 30% or less; and the remaining weight corresponding to a third glass plate.

[0068] In one or more embodiments of the present disclosure, the following table provides various embodiments of corresponding percentages of plate glass weight compared to the total glass weight of a triple plate glass IGU.

[0069] Table 2 shows various embodiments illustrating the percentage weight for each glass plate of a window assembly (compared to the total glass weight (glass plate (1) + glass plate (2) + glass plate (3))) according to the present disclosure:

[0071] As shown in FIG. 7, the diamond-shaped data point lies outside the shaded area, where the shaded area represents an edge sealing force greater than 1.2 N / m. Accordingly, one or more embodiments of the present disclosure include an edge seal that does not exceed 1.2 N / m when measured according to prEN 16612.

[0072] In some embodiments, the triple-pane window assembly includes an edge sealing force in the range of at least 0.05 N / m to 1.2 N / m or less when measured according to prEN 16612.

[0073] In some embodiments, the triple-pane window assembly includes an edge sealing force in the range of at least 0.1 N / m to 1 N / m or less when measured according to prEN 16612.

[0074] In some embodiments, the triple-pane window assembly includes an edge sealing force in the range of at least 0.3 N / m to 1 N / m or less when measured according to prEN 16612.

[0075] In some embodiments, the triple-pane window assembly includes an edge sealing force in the range of at least 0.3 N / m to 0.8 N / m or less when measured according to prEN 16612.

[0076] In some embodiments, the triple-pane window assembly includes an edge sealing force in the range of at least 0.2 N / m to 0.6 N / m or less when measured according to prEN 16612.

[0077] In some embodiments, the triple-pane window assembly comprises an edge sealing force of at least 0.05 N / m; at least 0.1 N / m; at least 0.2 N / m; at least 0.3 N / m; at least 0.4 N / m; at least 0.5 N / m; at least 0.6 N / m; at least 0.7 N / m; at least 0.8 N / m; at least 0.9 N / m; or at least 1 N / m when measured according to prEN 16612.

[0078] In some embodiments, the triple-pane window assembly includes an edge sealing force when measured according to prEN 16612: 0.05 N / m or less; 0.1 N / m or less; 0.2 N / m or less; 0.3 N / m or less; 0.4 N / m or less; 0.5 N / m or less; 0.6 N / m or less; 0.7 N / m or less; 0.8 N / m or less; 0.9 N / m or less; or 1 N / m or less.

[0079] FIG. 8 illustrates a cross-sectional view of a second window assembly (600). The window assembly (600) may include a first glass plate (130A), a second glass plate (130B), and a third glass plate (130C). A chamber gap (200) may be located between the glass plates (130), and a spacer (210) may be located within the chamber gap (200).

[0080] The first plate glass (130A) and the third plate glass (130C) may include a plurality of layers (230). In one embodiment, the third plate glass (130C) may include a first glass layer (230A), a first intermediate layer (230B), and a first glazing layer (230C). The first plate glass (130A) may include a second glass layer (230D), a second intermediate layer (230E), and a second glazing layer (230F). As illustrated in FIG. 8, the first glass layer (230A) and the second glass layer (230D) can be oriented in the same direction within the third glass plate (130C) and the first glass plate (130A), respectively (e.g., the first glass layer (230A) and the second glass layer (230D) are to the left of the third glass plate (130C) and the first glass plate (130A). In one embodiment, the first glass layer (230A) and the second glass layer (230D) can be oriented in a direction away from the interior of the structure, and the mass of the glass is shifted toward the direction away from the interior of the structure. Thus, the performance of the window assembly (600) is improved. Additionally, the first glass plate (130A) may be an external (e.g., facing outward) glass plate (130), and the third glass plate may be an internal (e.g., facing inward) glass plate (130).

[0081] As illustrated in FIG. 8, the first glass plate thickness (220A) may be greater than the second glass plate thickness (220B) and the third glass plate thickness (220C). The first glass layer (230A) has a first glass layer thickness (240A), the first intermediate layer (230B) has a first intermediate layer thickness (240B), and the first glazing layer (230C) has a first glazing layer thickness (240C). The second glass layer (230D) has a second glass layer thickness (240D), the second intermediate layer (230E) has a second intermediate layer thickness (240E), and the second glazing layer (230F) has a second glazing layer thickness (240F).

[0082] The thickness of the second glass layer (240D) may be greater than the thickness of the first glass layer (240A). For example, the thickness of the second glass layer (240D) may be in the range of approximately 3 mm to 6 mm (e.g., 3.2 mm), and the thickness of the first glass layer (240A) may be in the range of 2 mm to 3 mm.

[0083] In another embodiment, the thickness of the first glass layer (240A) may be equal to the thickness of the second glass layer (240D). For example, the thickness of the second glass layer (240D) may be within the range of approximately 2 mm to 6 mm, and the thickness of the first glass layer (240D) may be within the range of 2 mm to 6 mm. Accordingly, the thickness of the first plate glass (220A) may be equal to the thickness of the third plate glass (220C).

[0084] The thickness of the first glazing layer (240C) and the second glazing layer (240F) may be smaller than the thickness of the first glass layer (240A) or the second glass layer (240D). For example, the thickness of the first glazing layer (240C) and the second glazing layer (240F) may be 1 mm or less, and the thickness of the first glass layer (240A) or the second glass layer (240D) may be within the range of approximately 2 mm to 6 mm. Accordingly, the first plate glass (130A) or the third plate glass (130C) may be asymmetric, and the asymmetry within the layer (230) may improve the impact resistance of the first plate glass (130A) or the third plate glass (130C).

[0085] Additionally, the second glass plate thickness (220B) may be 1 mm or less or 2 mm or less. Thus, the second glass plate thickness (220B) may be smaller than the first glass layer thickness (220A) or the second glass layer thickness (240D). As discussed herein, when the second glass plate thickness (220B) is 1 mm or less or 2 mm or less, the performance of the window assembly (600) is improved (e.g., by shifting the glass mass away from the interior of the structure). In one embodiment, for example, by making the first glass layer thickness (240A) or the second glass layer thickness (240D) larger than the second glass plate thickness (220B) so that the glass mass is shifted away from the interior of the structure, the first glass layer (230A) or the second glass layer (230D) absorbs sound energy generated from the outside of the structure, and the acoustic performance of the window assembly (600) is thereby improved.

[0086] In one embodiment, the thickness of the second glass layer (240D) may be 4 mm or more, and the second glass layer (230D) may have a surface compression of 69 MPa or more. The thickness of the first glass layer (240A) may be within the range of approximately 2 mm to 3 mm, and the first glass layer (230A) may have a surface compression of 52 MPa or less (e.g., 24 MPa or less). The thickness of the first glazing layer (240C) and the second glazing layer (240F) may be 1 mm or less, and the first glazing layer (240C) and the second glazing layer (240F) may have a surface compression of 600 MPa or more. The second plate glass (130B) may have a surface compression of 24 MPa or less.

[0087] FIG. 9 shows a cross-section of the third window assembly (700). As described herein, the second glass plate (130B) may be positioned between the first glass plate (130A) and the third glass plate (130C) (e.g., the second glass plate (130B) may be the center glass plate (130). The first glass plate (130A) and the third glass plate (130A) may comprise a single material (e.g., soda-lime glass or glazing material). The second glass plate (130B) may comprise a plurality of layers (230C).

[0088] The first plate glass thickness (220A) may be greater than or equal to the second plate glass thickness (220B). The third plate glass thickness (220C) may be smaller than the first plate glass thickness (220A) or the second plate glass thickness (220B). For example, the third plate glass (130C) may comprise a low CTE or glazing material having a thickness of 1 mm or less. In some embodiments, the first plate glass (130A) may comprise a unitary (e.g., monolithic) plate glass of soda-lime glass, for example, within a range of approximately 3 mm to 8 mm. Additionally, the second plate glass thickness may be within a range of approximately 3 mm to 6 mm. Furthermore, the third plate glass (130C) may comprise a single partial glazing material or soda-lime glass.

[0089] In some embodiments, the second plate glass (130B) may comprise a plurality of layers (230), for example, a first layer (710A), a second layer (710B), and a third layer (710C). The second layer (710B) may comprise a first intermediate layer (230B) (shown in FIG. 2 and 6) or a second intermediate layer (230E) (shown in FIG. 8). The first layer (710A) and the third layer (710C) may comprise a glazing material such as the first glazing layer (230C) shown in FIG. 2 (e.g., a low CTE glazing material or a glazing material having a surface compression in the range of approximately 500 MPa to 700 MPa). The thickness of the first layer (710A) (720A) may be 1 mm or less, and the thickness of the third layer (710C) (720C) may be 1 mm or less. Accordingly, the second glass plate (130B) may be symmetric. In another embodiment, the first layer (710A) includes a first glass layer (230A) or a second glass layer (230D). Accordingly, the second glass plate (130B) may be asymmetric in one embodiment because the first glass layer (230A) is not commercially suitable with a thickness of 1 mm or less.

[0090] Referring again to FIG. 9, the third glass plate (130C) may include a glazing material, and the glazing material may improve the performance of the window assembly (700). For example, the glazing material may have greater scratch resistance than soda-lime glass. For example, the third glass plate (130C) may have a Knoop scratch threshold greater than 2 N (Newtons). The Knoop scratch threshold can be determined by joining an indenting member to the third glass plate (130C) and gradually increasing the force applied to the indenting member while moving the indenting member across the surface of the third glass plate (130C). It can be determined whether a scratch is formed on the surface of the third glass plate (130C) by observing the third glass plate (130C), and the force required to form the scratch can be determined, for example, based on the position where the scratch is formed relative to the starting position of the press-fit processing member.

[0091] In one embodiment, the third glass plate (130C) may have a Knoop scratch threshold in the range of approximately 2 N to 12 N (e.g., 2 N to 6 N, 4 N to 5 N, 4 N to 6 N, 8 N to 12 N). Soda-lime glass may have a Knoop scratch threshold of less than 2 N (e.g., 0.5 N to 1.5 N). In this embodiment, the third glass plate (130C) may be oriented toward the interior of the structure. Thus, the third glass plate (130C), which has greater scratch resistance, is oriented toward the interior of the structure, and the performance of the window assembly (700) is improved. In one embodiment, the third glass plate (130C) is cleaned, and as a result of the cleaning process (compared to soda-lime glass), resistance to scratch or abrasion is improved.

[0092] FIG. 10 illustrates one embodiment of a method (800) for manufacturing a window assembly, which comprises one or more of the window assemblies described herein. When describing the method (800), reference is made to one or more components, features, functions, and operations described above herein. For convenience, components, features, operations, etc. are referred to by reference numbers. The provided reference numbers are exemplary and not exclusive. For example, components, features, functions, operations, etc. described in the method (800) include, but are not limited to, equivalents with the corresponding numbered elements provided herein and other corresponding elements described herein (both numbered and unnumbered).

[0093] In (810), a first plate glass (130A) is obtained or provided (e.g., by a technician). The first plate glass (130C) may comprise a glass layer (230) having a glass layer thickness (240C). The first plate glass (130C) may comprise a glazing layer (230C) having a glazing layer thickness (240C). The glazing layer thickness (240C) may be smaller than the glass layer thickness (240A).

[0094] In (820), a second glass plate (130B) having a first glass plate thickness (e.g., a second glass plate thickness (220B)) is obtained or provided. In (830), a third glass plate (130C) having a second glass plate thickness (e.g., a first glass plate thickness (220A) or a third glass plate thickness (220C)) is obtained or provided. The first glass plate thickness may be smaller than the second glass plate thickness.

[0095] In (840), the second glass plate (130B) may be positioned between the first glass plate (130A) and the third glass plate (130C). The second glass plate (130B) may be spaced apart from the first glass plate (130A) by a chamber gap (200), for example, the first chamber gap (200A). The second glass plate (130B) may be spaced apart from the third glass plate (130C) by the second chamber gap (200B). In (850), the first glass plate may be combined with the second glass plate (130B) and the third glass plate (130C). In one embodiment, the first glass plate (130A), the second glass plate (130B), and the third glass plate (130C) may be joined together around the first glass plate (130A), the second glass plate (130B), and the third glass plate (130C). For example, the first glass plate (130A), the second glass plate (130B), and the third glass plate (130C) may be joined to the chassis (120).
