Casement Window vs Sliding Window, Is Not Only Different In Appearance!

Sliding window

The sliding window adopts the window sash equipped with pulley to slide on the track on the window frame, which is divided into left and right, up and down. It adopts high-grade slide rail, which can be opened flexibly with a slight push. With large pieces of glass, it not only increases the indoor daylighting, but also improves the overall shape of the building. The stress state of the window sash is good and not easy to be damaged, but the ventilation area is limited to a certain extent.

Advantages

It does not occupy indoor space, beautiful appearance, economic price and good sealing. Sliding windows are generally most suitable for high-rise buildings with more than two floors, because the opening mode is push-pull, and the windows will not be outside like casement windows. In order to avoid falling objects, sliding windows are most suitable for high-rise buildings.

Disadvantages

Only 50% of the window sashes can be opened at most, and the air tightness is poor when closed. In recent years, there are improved sliding windows with new technology, which can push multiple window sashes to one side for folding. At the same time, there are also sliding windows to improve air tightness, but generally speaking, they still can not achieve the thermal performance of casement windows, and the energy consumption is high.

Casement window

Casement window is divided into push-pull type and upper suspension type.

Advantages

Large opening area, good ventilation, good sealing, excellent sound insulation, heat preservation and impermeability. The inner opening is convenient for cleaning windows; The open type does not occupy space when it is opened.

Disadvantages

The window width is small and the field of vision is not wide. The opening of the external window takes up a space outside the wall, which is easy to be damaged in strong wind; The internal opening of windows takes up part of the indoor space, and it is inconvenient to use screen windows. If the quality is not up to standard, it may also seep water.

📌Appearance

Because of its great flexibility of division, casement windows can make any line facade effect, and for large division floor to ceiling windows, the opening fan only accounts for a small part of the whole window, so it is more suitable for high-end buildings with strict requirements for the overall effect of the building, It is especially in line with the architect's pursuit of a large grid, spacious and bright, good permeability effect and harmonious and smooth appearance. Because the opening position of sliding window can only be pushed and pulled horizontally, it is difficult to match with the fixed glass with large division. Generally, it is more suitable for business plants or rural family buildings with clear horizontal and vertical lines.
