Transparent reflective heat-insulating window curtain for external window of building

Abstract

The invention discloses a transparent reflective heat-insulating window curtain for an external window of a building. The base film of the window curtain is a nylon film, a terylene film, a polyester film or other similar transparent plastic films with certain rigidity and capable of being curled around a circular shaft. The thickness of the base film is 0.05mm to 1.5mm. The surface of the base film is coated with nanometer transparent heat-insulation coating to form the transparent reflective heat-insulation window curtain. The main function of the window curtain is to reflect infrared heat irradiated by sunlight to a window in summer, but the permeability of visible light is not obviously influenced. The opening/closing type of the window curtain is an around-shaft rotating type. When the infrared heat irradiated by the sunlight to the window is required in winter, the window curtain can be conveniently disassembled.

Description

Technical field: [0001] The invention relates to a transparent reflective and heat-insulating curtain used for external windows of buildings. The transparent reflective and heat-insulated curtain can reflect the infrared heat radiated from sunlight to the room through the window in summer, so as to reduce the indoor temperature and save energy. The use of the transparent reflective heat-insulating curtain can replace other energy-saving windows with similar functions, such as low-E glass energy-saving windows, hollow coated glass energy-saving windows, etc. Background technique: [0002] Windows are structural parts that are difficult to achieve building energy efficiency, and have become a major obstacle to improving building energy efficiency standards. The reflective heat insulation technology used for building exterior window glass is mainly hollow coated glass. The disadvantage of this type of technology is that while the window reflects the infrared heat radiated by su...

AI Technical Summary

Problems solved by technology

The reflective heat insulation technology used for building exterior window glass is mainly hollow coated glass. The disadvantage of this type of technology is that while the window reflects the infrared heat radiated by sunlight to the window in summer, it also transmits the required sunlight to the building in winter. The infrared heat radiated by the external windows is reflected, causing energy loss and increasing the heat loss of the external windows of the building in winter

The application of these technologies is limited in cold, hot summer and cold winter, and even hot summer and warm winter climate zones

At the same time, none of these technologies can be applied to the exterior windows of existing buildings.
