Description

technical field [0001] The invention relates to a window, in particular to a replaceable casement window with an invisible screen window. Background technique [0002] With the promotion and application of building energy-saving doors and windows in engineering projects by the Ministry of Housing and Urban-Rural Development of my country, most provinces and cities have basically used broken bridge energy-saving doors and windows in projects that have been completed in recent years or are currently under construction. Among these broken bridge energy-saving doors and windows, casement windows are favored by real estate developers because of their good airtightness, watertightness and wind pressure resistance and moderate cost, making casement windows the most window type at this stage. [0003] Existing conventional casement windows are only equipped with glass, and the window is opened or closed by hardware. In the season when there are many mosquitoes, opening the window wil...
