Generally, the desktop is installed first, and then packaged. Desktop: 3 cm away from the front edge (generally double rounded corners), 8- 10 cm away from both ends, and the sleeve line (generally 6-8 cm) is pressed against the front edge. I would also like to ask how big the gap between the side marble and the wall is, but generally it is best not to exceed 1 cm. But in practice, as long as it does not interfere with the window opening and does not exceed the width of the set of silk, it can be wound. But from a technical point of view, more than 2 cm is unqualified.
Generally, the window width starts from 0.6m, which is wide enough to form a "window opening". However, when using a window with a larger width, attention should be paid to the sound insulation of the adjacent rooms and the sliding range of the sliding window. It should also be noted that fully opening the window width of a room will cause glare on the transverse wall, which is not suitable for classrooms and exhibition rooms. In general residential buildings, the window height is 1.5m, the window sill height is about 0.9m, and the height from the top of the window to the ground is about 2.4m When the window sill height is less than 0.8m, protective measures should be taken. The width of the window usually starts from 0.6 meters and is wide enough to form a "window opening". When wide windows are used, the sound insulation in the next room is a problem. If a sliding window is used, the sliding range of the sash should be considered.
