Description

Additional Window using Vacuum Insulation Panel made of Synthetic Resin, Its Manufacturing Method, and Installation Method for Insulated Shutter The present invention relates to a window frame using a vacuum insulation panel made of synthetic resin, a method of manufacturing the same, and a method of installing an insulating door. More specifically, the invention relates to a window frame using a vacuum insulation panel made of synthetic resin, a method of manufacturing the same, and a method of installing an insulating door, which is manufactured using a vacuum insulation panel in which a vacuum layer is formed between an upper plate and a lower plate made of transparent synthetic resin to provide visibility while possessing excellent thermal insulation and impact resistance. A significant number of buildings are severely deteriorated, and are exposed to an inefficient thermal energy environment due to the complete omission of insulation or extremely low insulation efficiency. In other words, most aging buildings exhibit limitations in building energy usage, such as relatively high base consumption, because the insulation efficiency of windows, doors, walls, and roofs is very low. Consequently, despite the operation of heating and cooling systems, it is difficult to expect sufficient cooling effects due to the relatively low insulation efficiency, and significant costs are incurred for these functions. In addition, when applying green remodeling technology to improve the energy efficiency of aging buildings, there are often cases where windows, doors, walls, and ceilings cannot be completely removed due to structural problems of the aging buildings, and there are limitations to practical implementation due to various issues such as narrow distances between buildings, discrepancies between residents and actual building owners, and costs. Meanwhile, by installing additional windows on existing windows or attaching window film to block sunlight, the energy consumption efficiency of aging buildings can be improved at a low cost without spatial or structural constraints. As a prior art document related to such an overlay window, Korean Registered Patent No. 10-2548623 (registered on June 23, 2023, hereinafter referred to as 'Prior Art Document 1') has been proposed as the applicant's previously registered patent. As shown in FIG. 1a, the overlay window according to Prior Art Document 1 comprises an overlay window (4) that forms an air layer (3) by being spaced at a certain distance from the indoor glass (2) of the existing window (1), a frame (5) installed to surround the edge of the overlay window (4), and an adhesive means provided on the frame (5) to be attached to the indoor glass (2). The additional window of Prior Art Document 1 described above is attached to the existing window (1) so that an air layer (3) is formed between the existing window (1) and the additional window (4), thereby allowing for improved thermal insulation performance without changing the structure of the existing window. As such, Prior Art Document 1 improves the thermal insulation performance of the existing window by forming an air layer through the additional installation of the additional window (4), but it is difficult to maintain the sealing of the air layer, and since air contains a large number of molecules compared to a vacuum, there is inevitably a limit to improving thermal insulation performance due to convection of molecules. Meanwhile, vacuum insulation panels (VIP) are being used as insulation materials for construction or for heating and cooling equipment. A prior art document related to such vacuum insulation panels is Korean Registered Patent No. 10-2211452 (registered on January 28, 2021, hereinafter referred to as 'Prior Art Document 2'). As shown in FIG. 1b, the vacuum insulation panel of Prior Art Document 2 includes a core material (11) and a sealing film (12) that surrounds the core material (11). This vacuum insulation panel can be manufactured by placing the core material (11) into the sealing film (12) and then sealing the sealing film (12) in a vacuum state. Prior art document 2 describes a method to minimize material loss during the manufacturing process of vacuum insulation by connecting a vacuum nozzle to a vacuum film without using an expensive vacuum chamber. However, fundamentally, in the case of vacuum insulation where the core material is wrapped in an outer shell, it is difficult to ensure visibility due to the core material, so it cannot be used as a window covering, and above all, the outer shell is very vulnerable to scratches or external impacts, so a protective layer is required. In particular, since it is difficult to manufacture vacuum insulation materials into panels of a certain size or larger, they are produced by joining multiple individually manufactured unit panels together, which results in thermal bridging between the unit panels and requires a process of wrapping them with a separa
