Large Sliding Patio Windows

The difference between sliding windows and casement windows

1. Operation method:

Casement window: Casement window is opened and closed on the window frame by hinges. When opened, the window rotates inward or outward to open, forming a fixed opening.

Sliding window: Sliding window slides back and forth on the window frame by rails. When opened, the window can slide horizontally, one side slides open and the other side closes.

2. Appearance difference: Casement window has great flexibility and can be made into any line facade effect. It is suitable for large-style floor-to-ceiling windows and buildings with strict requirements on the overall effect of the building. Sliding window can only be pushed and pulled horizontally, and there is no large glass view surface, so it is suitable for buildings with clear horizontal and vertical lines.

3. Performance difference: Casement window is generally superior to sliding window in wind resistance, water tightness and air tightness. This is due to the characteristics of its design and construction. For high-rise buildings, due to the greater influence of factors such as wind force and air pressure, it is crucial to choose a window type with better wind resistance, water tightness and air tightness. In these cases, casement window may be a better choice.

4. Difference in thermal insulation performance: The thermal insulation performance of casement windows is better than that of sliding windows. Since it uses two-point locks or floor locks with sealing strips for locking and sealing, this design can effectively reduce air infiltration and moisture infiltration. Sliding windows are generally locked with hook locks or touch locks. Although they can also achieve a certain sealing effect, their sealing performance may be slightly inferior to that of casement windows.

5. Difference in lighting area: Casement windows can be used with fixed glass, and its lighting area can be maximized, solving the problem that the large area of ​​glass in the living room was only fixed but not opened. Sliding windows use window sashes equipped with pulleys, which slide horizontally on the track on the window frame. Generally, a large-grid fixed glass design is used, which does not occupy the living room space.

6. Safety difference: If the casement window is facing inward, it is easy to hit the head, and the opening angle outward will be limited, and sometimes it cannot be fully opened. Sliding windows do not have these problems, so the safety performance of sliding windows is better than that of casement windows.
