Get Every Answers About sliding windows
Sliding windows open and close by moving one or more sashes along a track, either horizontally (for horizontal sliding windows) or vertically (for vertical sliding windows). This smooth movement is enabled by:
- Rollers: Mounted on the movable sashes to allow easy, low-friction sliding.
- Guides: Fixed to the window frame to direct and support the sashes during operation.
This design means that sliding windows do not take up any extra space when open, making them ideal for rooms with limited space.
Sliding windows are windows that open and close by sliding rather than relying on a rotating or tilting mechanism. They usually consist of at least one movable sash that slides along a horizontal or vertical path. They usually open and close by simply pushing the movable sash.
Here are some common sizes:
24 x 48 inches: Often used in bathrooms or smaller spaces
60 x 48 inches: Common in dining rooms, larger kitchens, living rooms, and bedrooms
72 x 60 inches: Large standard size commonly used in living rooms and bedrooms
Grandsea offers sliding windows that can be customized to your visual needs with different sizes and functions.
