Windows are a channel for people to look outside when living indoors. One side of the windows is a world of various styles, while the other side is a small space that belongs to their own ease. Even in ancient times, windows were divided into many types, but now the types of windows are more abundant. Casement window, sliding window, suspended windows and so on are all very common in homes, however, do you know the difference between casement window and sliding window? Let's learn about it together.
What is casement window?
The so-called casement window is a window that can be horizontally switched. This type of window is defined according to the opening method of the window and is widely used in various decoration places at present.
The advantages are large opening area, good ventilation, good sealing performance, excellent sound insulation, heat preservation and impermeability. The open window is convenient to clean; The open window does not occupy space when it is opened.
The disadvantage is that the window width is small and the vision is not wide. The opening of outwards opening window takes up a piece of space outside the wall, which is easily damaged when the wind blows; While the opening of in-swinging casement window takes up part of the indoor space, it is not convenient to use car window shade, and it is also inconvenient to use car window shade and curtains when opening the window, if the quality is not good, it may rain.
What is sliding window?
About sliding window points, push and pull up and down. Sliding window the Casement equipped with pulleys on the window frame is adopted. The advantage of this kind of window is that the window does not occupy extra space no matter in the switch state, and the structure is relatively simple.
Sliding window has the advantages of not occupying indoor space, beautiful appearance, economical price and good sealing performance. High-grade slide rail is adopted, and it can be opened flexibly with a gentle push. With large pieces of glass, it not only increases indoor lighting, but also improves the overall appearance of the building. The stress state of Casement is good and not easy to be damaged, but the ventilation area is limited to some extent.
The disadvantage is that only Casement of 50% can be opened at most, and the air tightness is poor when closed. In recent years, there are improved sliding window using new technologies, which can push multiple Casement to one side and fold them. At the same time, there are also sliding window to improve air tightness, but generally speaking, it still cannot achieve casement window thermal performance and high energy consumption, so this kind of window is rarely used in advanced countries.
The difference between casement window and sliding window:
1. Different appearance
The difference between casement window and sliding window in appearance mainly lies in the matching with the overall style of the building. Casement window can make any line facade effect due to its flexibility in grid division, and for the large divided floor-to-ceiling windows, the opening fan only accounts for a small part of the whole window, so it is more suitable for high-grade buildings with strict requirements on the overall effect of buildings; sliding window because the opening fan position can only be pushed and pulled horizontally, it is difficult to match the fixed glass with large grid. Generally, it is more suitable for opening workshops or rural family buildings with clear horizontal and vertical lines.
2. Different prices
There is little difference between casement window and sliding window at the same price, casement window is slightly higher than sliding window. The price of ordinary flat opening aluminium windows is 200~350 yuan/square meter, and the price of medium and high-grade windows is more than 460 yuan/square meter. Sliding doors and windows are generally 150~200 yuan/square meter.
3. Thermal effect
In terms of thermal insulation performance, sealant strips are generally used to seal open windows on the market, while sliding window is generally used to seal wool tops. The sealing effect of adhesive strips is generally better than that of wool tops. The opening fan of casement window is mostly locked and sealed by two-point lock or Heaven and Earth lock, and its sealing effect is better. However, sliding window is generally locked by Hook Lock or spring lock, and its sealing effect is not ideal.
4. Performance
Casement window is generally better than sliding window in the three properties of doors and windows (wind pressure resistance, watertightness and air tightness). The wind pressure resistance of doors and windows depends on the resistance moment of the main force bar of doors and windows. The larger the section of the profile, the larger the resistance moment, but it is not completely proportional. The watertightness of doors and windows depends on the sealing effect of the opening part, and casement window is generally sealed by adhesive tape. In terms of air tightness, casement window of the open fan parts on the market use two-point lock or Sky lock for locking and sealing.
5. Manufacturing process
In terms of processing and manufacturing, sliding window is generally simple in structure and has no special requirements for equipment, so it is processed and manufactured by a small workshop with a small chainsaw; Casement window because it is connected by thick aluminum alloy corner fitting 45 degrees, therefore, better "angle collision machine" and "double-headed cutting saw King" are needed to produce excellent aluminum alloy casement window casement window.
After understanding the above content, I believe everyone has a certain understanding of what is the difference between casement window, casement window and sliding window. The window is the eye of a room, we can understand the outside world while shielding us from the wind and rain, so we can't be careless.
