As shown, FIG. 7A is configured with a single defined gap 18 between the existing window 10 and the first laminate 110, while FIG. 7B is configured with two defined gaps, a first defined gap 18 and a second defined gap 128 between the first laminate 110 and the second laminate 120. Since the gap 128 is configured with sealing engagement between two laminates, the seal (seal 106 and spacer 104) and frame 102, the gap 128 is configurable a gas sealed therein (e.g. to provide thermal insulation properties/improved thermal performance).
[0126] It is noted that the extension portion 140 of the frame 102 is also configurable to extend beyond the existing frame 102, such that the fenestration apparatus 100 is configured to (a) rest within an existing frame 12 on the windowsill 14 and be retained via an attachment member 132 that comprises a compression member 138; and (b) extend adjacent to the existing fenestration assembly area 16 surrounding the existing frame 12 (e.g. wall), such that the frame extension 140 is configured to mechanically attach via a mechanical attachment member 134 to the area surrounding the existing fenestration assembly 16, in accordance with one or more aspects of the present disclosure.
[0127] It is noted that the extension portion of the frame 102 is also configurable to extend beyond the existing frame 12, such that the fenestration apparatus is configured to (a) rest within an existing frame 12 and be retained via an attachment member 132 that comprises a compression member 138; and (b) extend adjacent to the existing fenestration assembly area 16 surrounding the existing frame 12 (e.g. wall), such that the frame extension 140 is configured to mechanically attach via a mechanical attachment member 134 to the fenestration assembly area 16 surrounding the existing frame 12, in accordance with one or more aspects of the present disclosure.
Example: Modeling of Fenestration Apparatus Embodiments vs. Comparative Examples
[0128] Computer modeling was completed to evaluate the difference in acoustic performance for various fenestration assemblies disclosed herein, as compared to comparative examples. Commercially available WINDOW and INSUL software was utilized to model several configurations of fenestration assemblies, with comparative results (e.g. total thickness; Sound Transmission Class, as measured in accordance with ASTM E413, and sound reduction, as measured in accordance with ASTM E1332 (Outdoor Indoor Transmission Class) set forth herein in the table below.

[0129] Comparative Example 1 provides an existing single pane window having 3 mm of soda lime glass. Comparative Example 2 provides a double insulated glazing unit, having two thick soda lime glass sheets separated by a gap of air in between. Design 1 provides a fenestration apparatus having a single laminate comprising 2 thin glass sheets and a polymer interlayer, as described in the present disclosure. This is also referred to as a double IGU (i.e. when functioning in place, over a 3 mm thick piece of soda lime glass/the existing fenestration assembly). Design 2 provides a fenestration apparatus having two laminates, where each laminate is configured of thin glass (e.g. <1 mm thick borosilicate glass) with a polymer interlayer positioned therebetween, configured in spaced relation via a spacer and secondary seal, as described in the present disclosure. This is also referred to as a triple IGU (i.e. when functioning in place, over a 3 mm thick piece of soda lime glass/the existing fenestration assembly).
[0130] The table depicts the parameters of various retrofit windows and shows the modeling results of various parameters, including weight, thermal performance, and acoustic properties for several window configurations. The reported values are for the center of glass (COG) performance; the full window values will depend on the window size and installation details such as framing.
[0131] Comparative Example 1, the existing single-pane window, has a high Ug-value, which represents high heat loss and is undesirable in cold climates/seasons. It also has a high solar heat gain coefficient (SHGC), which is undesirable in warm climates/seasons.
[0132] In contrast, Comparative Example 2, the thick double IGU, has considerably lower Ug and SHGC. It also reduces sound transmission through the window, as indicated by its higher STC and OITC values. However, the weight of the glass is double that of Comparative Example 1, making the SGS difficult to handle and install. In many historic buildings the existing framework may not be capable of handling the additional glass weight.
[0133] Design 1, using a thin glass laminate, also offers lower Ug and SHGC than Comparative Example 1. Design 1 is able to match the improved thermal properties of Comparative Example 2 at a weight closer to that of Comparative Example 1. Furthermore, the acoustic performance of Design 1, as measured by STC and OITC, is better than the considerably heavier Comparative Example 2. Addition of a second thin glass laminate, as in Design 2, further improves the thermal and acoustic properties at a weight less than that of Comparative Example 2.
[0134] Ranges can be expressed herein as from about one particular value, and/or to about another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent about, it will be understood that the particular value forms another embodiment. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. As a non-limiting example, about means less than 10% of the referenced value.
[0135] Directional terms as used hereinfor example up, down, right, left, front, back, top, bottomare made only with reference to the figures as drawn and are not intended to imply absolute orientation.
[0136] Unless otherwise expressly stated, it is in no way intended that any method set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not actually recite an order to be followed by its steps, or it is not otherwise specifically stated in the claims or descriptions that the steps are to be limited to a specific order, it is in no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including matters of logic with respect to arrangement of steps or operational flow; plain meaning derived from grammatical organization or punctuation; the number or type of embodiments described in the specification.
[0137] As used herein, the singular forms a, an and the include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a component includes aspects having two or more such components, unless the context clearly indicates otherwise.
[0138] Many variations and modifications may be made to the above-described embodiments of the disclosure without departing substantially from the spirit and various principles of the disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure and protected by the following claims.
