1. The influence of window sash distribution ratio
In the window sash layout of the three track sliding window, the window sash distribution ratio has a direct impact on indoor lighting and vision. If the window sash area accounts for a larger proportion of the entire window frame area, more natural light can enter the room, thereby improving the indoor lighting effect. For example, when the fixed sash in the middle is smaller and the sliding sashes on both sides are larger, the lighting area increases and the room will appear brighter. In terms of vision, larger window sashes can also provide a wider field of vision, allowing residents to see more outdoor scenery, whether it is distant scenery or close courtyards.
2. Window sash track position and lighting vision
The position of the window sash track affects lighting and vision. If the track is designed at the edge of the window frame, the occupation of the middle lighting area should be minimized as much as possible, so that light can enter the room unimpeded. For example, a narrow track design is used to reduce the blockage of light by the track, and the indoor lighting effect will be better. From the perspective of vision, this layout makes the line of sight more transparent, and there will not be too much visual segmentation due to the existence of the track, which is conducive to forming a coherent field of vision, making people feel closer to the outdoor environment.
3. The influence of multiple sash combinations
Three track sliding windows can have different window sash combinations, such as double fixed sashes plus single sliding sashes or single fixed sashes plus double sliding sashes. The layout of double fixed sashes plus single sliding sashes may be relatively limited in terms of lighting, because the fixed sashes cannot be fully opened, which will block some light from entering. The layout of single fixed sashes plus double sliding sashes can open the double sliding sashes to the maximum extent when lighting is needed, allowing more light to enter the room, while also providing a wider field of view, especially when the double sliding sashes are opened to the same side, the line of sight can be focused in one direction, making the field of view wider.
4. Window sash opening direction and indoor effect
The opening direction of the window sash also affects the lighting and field of view. If the window sash opens to the room, it may occupy a certain amount of indoor space when it is opened, and to a certain extent affect the field of view near the window area. The window sash that opens outwards can avoid this problem. While not occupying indoor space, it will not cause additional obstruction to the indoor field of view. Moreover, when opened, the windows that open outwards can allow more light to enter the room at a larger angle, further improving the indoor lighting effect.
