1. Beautiful and generous. In order to prevent mosquitoes and theft of traditional casement windows, additional protective windows and screens need to be installed, which causes the overall chaos of doors and windows and affects the aesthetics of the decoration. The integrated window screen integrates energy-saving windows, protective windows, and screen windows as a whole, and has various opening methods. The indoor and outdoor two-color styles can be arbitrarily matched, which is truly beautiful and generous. 2. Heat insulation and energy saving. High-quality insulating glass is used to prevent cold and warmth while minimizing noise interference in the room. It has excellent sound insulation, heat insulation and heat preservation functions, and saves a lot of heating and cooling costs. The energy-saving costs of several years of window screens are enough to make up for the initial investment. 3. Anti-mosquito and ventilation. The sliding and side-opening integrated screens are suitable for high and low floors and have safety devices. In addition to ventilating and preventing mosquitoes, screen windows can also prevent wind blowing garbage or debris into the house, and can be properly isolated, making the home environment cleaner and more conducive to physical and mental health.
