It was established earlier. Many first-and second-tier cities in China have their own stores. After so many years of development, it has a good reputation and popularity in the industry and is a relatively good first-line brand enterprise. The advantages are large opening area, good air permeability, good sealing performance and excellent sound insulation, heat preservation and impermeability. The disadvantage is that the window width is small and the field of vision is not wide. The outer window takes up the space outside the wall, which is easy to be damaged when it is windy, while the inner window takes up part of the indoor space, so it is inconvenient to use screen windows, screens and curtains. When opening the window, if the quality is not up to standard, it may leak rain.
The advantages of sliding window are simple and beautiful, wide window, large glass block, wide field of vision, high daylighting rate, convenient glass cleaning, flexible use, safety and reliability, long service life, opening in one plane, less occupied space and convenient installation of screen window.
