Three rails sliding window disadvantages:
1. Space issues.
Sliding window does not occupy indoor and outdoor space. You can control the opening area at will. It is easy to operate and is especially suitable for windowsill. Folding open doors and windows is suitable for a large area of space. When opening and closing doors and windows, the edge is track gliding, which is easy to operate. However, the maximum opening degree can only reach 1/2 of the whole window area; In rainy days, the window can only be closed and cannot be ventilated; Cleaning is relatively difficult, and it is very difficult to wipe the outside side of the glass; moreover, the sealing performance is poor, moisture and dust are easy to enter, and the energy saving effect is not good. The window frame bottom slide rail slides back and forth, with a large space on it and a gap between pulleys below, forming a large heat loss.

Currently, sliding window is the most widely used. The disadvantage is that the two windows can not be opened at the same time, only half can be opened at most, and the ventilation is relatively poor; Sometimes the sealing is also slightly poor.
