Removable Overlap Glass System with Low-E Film for Improving Thermal and Radiant Comfort Performance of Existing Windows

The present invention relates to a glass system for adding to an existing window to improve insulation and radiant comfort performance, and more particularly, to a glass system for adding to an existing window by attaching a high-performance low-E film to the innermost glass portion of the existing window and fixing a transparent body made of glass or plastic, or by using a magnetic tape to easily attach and detach the glass.

Commercial and public buildings, primarily used during the day, have a large window area ratio (the ratio of the wall area occupied by windows). Therefore, during the long summer days, solar heat enters through windows, increasing energy consumption for cooling. Furthermore, in winter, low-insulation windows allow heat to escape indoors, increasing energy consumption for heating.

Low-e film is a radiant heat-blocking material applied to glass or other transparent surfaces to reduce emissivity and improve energy efficiency. It is primarily applied to windows and glass doors in buildings to block solar radiation and stabilize indoor temperatures, thereby reducing heating and cooling costs. This film blocks solar energy through a nanoscale metallic coating on the glass surface, maintaining light transmittance while blocking radiant heat, contributing to maintaining a comfortable indoor temperature.

Replacing existing windows with new ones is a viable way to improve their insulation performance. However, this can be lengthy and expensive, leading to alternatives like installing low-E film or repairing the window frames. These methods offer the advantages of being less expensive than window replacement, maintaining the original window's design, and improving insulation and radiant comfort without replacing the existing window.

Korean Patent No. 10-2034569 relates to [an additional window], and the invention discloses a technology including an additional window provided at a predetermined distance from the glass of an existing window, a spacer provided between the glass and the additional window to separate the additional window from the glass at a predetermined distance, and a fixing member provided on the edge of the additional window to fix the additional window to the window sash of the existing window. However, the above-mentioned registered patent only has one additional layer of glass and does not include a low-e film in the components, so it is difficult to expect sufficient insulation effect or improvement in radiant comfort performance. In addition, since it is a fixed method rather than a detachable method, the low-e film surface can be switched for use according to the season, and it is difficult to use and maintain it, such as cleaning.

The present invention relates to a technology for applying high-performance low-e film to laminated glass for green remodeling of existing buildings, and more specifically, to a technology for improving the insulation performance of existing windows using high-performance low-e film without removing the existing windows. Recently, high-performance low-e films with very low emissivity of 0.10 to 0.15 or less have been developed, which show performance close to the emissivity performance of low-e glass directly coated on glass. Unlike low-e glass, such low-e films can be easily attached to existing windows, and thus can be very effectively applied to improving the insulation performance of windows in the existing construction market rather than in new construction. In residential buildings where heating accounts for the majority of total energy consumption, heat loss path flows from the interior to the exterior, and therefore, the location of the low-e coating layer toward the interior side of the glass that constitutes the double-glazed window is advantageous for improving insulation performance.

When low-e coating is applied to the interior surface of the glass located at the innermost part of a double-glazed window, the emissivity is very low, so it can significantly improve heat loss by reflecting a significant portion of the long-wave radiation emitted toward the window from all the walls that make up the indoor space. However, at the same time, the temperature of the low-e coated surface of the glass is also maintained very low, so there is a relatively higher possibility of surface condensation on the interior window surface in winter, and the radiant comfort performance due to cold radiation around the window is also likely to be reduced. Therefore, the most appropriate location for applying low-e coating to double-glazed windows in buildings that prioritize heating is the exterior surface of the glass located at the innermost part, rather than the interior surface. In the case of double-glazed windows with two or more movable window frames, it is possible to install low-e film on the exterior surface of the innermost glass because they can be opened. However, it is not applicable to fixed windows such as windows or curtain walls that cannot be opened.

Considering these points, by attaching a new glass window or a plastic transmissive material with a high-performance low-E film to the interior-most glass portion of an existing window, the insulation performance and radiant comfort performance can be improved simply without removing the existing window. Hereinafter, an embodiment of the present invention will be described with reference to the attached drawings.

FIG. 1 is a conceptual diagram illustrating a detachable additional glass system (30) using a low-e film applied according to one embodiment of the present invention, applied to an existing window (100). In one embodiment of the present invention, the existing window (100) may be a double-glazed window (10) or a double-glazed window (20) including the double-glazed window, one side of which is in contact with the exterior side (A) and the other side is in contact with the interior side (B). The present invention provides a detachable additional glass system using a low-e film for improving the insulation and radiant comfort performance of an existing window, comprising: an additional glass window frame (not shown) in which the additional glass is spaced apart from the interior-most glass (11) of the existing window in the interior direction by a predetermined distance and is maintained parallel to the plane of the interior-most glass (11); an additional glass fixing part for detachably fixing the additional glass window frame; And it includes a transparent body (31) made of additional glass or plastic, which is fitted into the additional glass window frame and has a low-e film (32) attached to one side. In one embodiment of the present invention, the interior-side glass (11) refers to the glass closest to the interior space before the additional glass is added, i.e., the glass that is in contact with the interior space.

In one embodiment of the present invention, the additional glass window frame has a planar symmetrical structure so that the direction of the surface to which the low-E film of the additional glass is attached can be changed and fixed. In one embodiment of the present invention, the additional glass fixing member is a first magnetic bonding member (15) arranged to be bonded along the edge of the glass surface facing the interior of the existing window, and the additional glass window frame is a second magnetic bonding member (35) arranged at a position opposite to the first magnetic bonding member so as to be magnetically bonded to the additional glass fixing member on the edge of both sides or one side of the additional glass, and when the first magnetic pole is a N pole, the second magnetic pole is a S pole, and when the first magnetic pole is a S pole, the second magnetic pole is a N pole. In addition, in one embodiment of the present invention, the first pole magnetic joint and the second pole magnetic joint are formed on the upper surface of a TPS (Thermo Plastic Spacer) insulating flat bar bonded to glass.

In one embodiment of the present invention, the second magnetic bonding member (35) arranged on one side of the transparent body of the additional glass or plastic of the additional glass window frame is detachable so as to change the direction of the transparent body surface of the glass or plastic. In addition, the additional glass window frame is a magnetic tape or a magnetic tape having a magnetic property that can be attached to a magnetic tape that can be fixed to the window frame or the glass surface when the existing window is a fixed window, or to the glass surface when the existing window is an openable window, and the additional glass fixing member is a fastener that detachably fixes the additional glass window frame, which is the fixable frame, to the window frame or the glass surface when the existing window is a fixed window, or to the glass surface when the existing window is an openable window. In one embodiment of the present invention, the fastener includes a rotating fixed anchor bolt and a length-adjustable telescopic support.

The above-mentioned detachable laminated glass technology using magnetic tape is a construction method for attaching new laminated glass with low-e film to the glass of an existing window, and enables easy attachment and detachment using magnetic tape. The adhesive method using spacers and butyl, etc., which maintain the gap between the glasses like existing windows, is a method for completely fixing them after attachment. If the low-e film is attached to the interior-most glass (11) of an existing window without laminated glass with high-performance low-e film applied, the location of application of the low-e coating in winter is advantageous for preventing condensation and improving radiant comfort performance when installed on the exterior surface (12) of the interior-most glass. In the case of an air-conditioned room, the location of application of the low-e coating, which is advantageous for improving insulation performance and radiant comfort performance, can be selected as the interior surface (13) or the exterior surface of the interior-most glass depending on the indoor heat generation characteristics. Therefore, when the low-e film-applied additional glass is applied to the interior-facing side of the existing window, if it is removable, the application location of the low-e coating can be selectively changed according to seasonal conditions, thereby achieving optimal performance.

In addition, unlike the laminated glass work that is airtightly manufactured in a factory, the laminated glass technology that must be installed on-site has a structural limitation that, even with precise installation, leakage of the air layer formed by the laminated glass and internal condensation inevitably occur in the long term. Adopting a detachable method also has the advantage of allowing for easy cleaning and maintenance. In one embodiment of the present invention, the method for installing the detachable laminated glass is as follows: first, magnetic tape is attached to the four end surfaces of the glass window of the existing window to be attached, and in the same way, magnetic tape or a magnetic tape that can be attached to the magnetic tape is attached to the four end surfaces of the “Low-E film applied laminated glass” on both the indoor and outdoor sides. In cases where the position of the Low-E coating does not need to be changed depending on the season, the magnetic spacer is attached to only one side of the “Low-E film applied laminated glass”.

Although the exemplary embodiments of the present invention have been described in detail above, the scope of the rights of the present invention is not limited thereto, and various modifications and improvements made by those skilled in the art using the basic concepts of the present invention defined in the following claims also fall within the scope of the rights of the present invention.
