What's the difference between aluminum alloy casement window and sliding window? Which one is good at sound insulation?
Many friends who need to decorate and install aluminum alloy doors and windows will have the same question. Which window type is more beautiful and which aluminum alloy doors and windows are more user-friendly and practical? Now more popular on the market, multi customer selection of window type to the number of push-pull and open two. Flat doors and windows are installed on the side of doors and windows to open inward or outward; sliding doors and windows mainly refers to the windows and doors that are vertically pushed and pulled along the horizontal direction. Push pull and flat open in the use of the same glass and accessories, compared with each other, the following on the appearance of doors and windows, performance, price, sound insulation effect and use of functions and other aspects of their respective characteristics.

Difference 1: appearance
The difference between the casement window and the sliding window in appearance lies in the collocation with the overall style of the building. Due to the flexibility of the partition, the casement window can make the facade effect of any line. Moreover, for the floor to ceiling window with large partition, the opening window 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 the building, Especially in line with the architect's pursuit of large division, spacious and bright, good transparent effect, harmonious appearance of the building. Because the opening position of the sliding window can only be horizontal, it is difficult to match with the fixed glass with large division. Generally, it is more suitable for opening workshops or rural family buildings with clear horizontal and vertical lines.
Difference 2: sound insulation
Which good sound insulation effect is aluminum alloy casement window and sliding window? The first is the difference in glass materials. Generally, the glass of casement windows is obviously thicker than that of ordinary aluminum alloy push-pull windows; the second is the window frame, because the aluminum alloy casement window is like the letter slot window frame, so it is occluded more closely when it is closed; the third is the fixed mode, because the casement window does not need loose leaves, so it will not shake and loosen basically. The sound is generated and transmitted by vibration Its stability hinders the transmission of sound; finally, the structure, aluminum alloy casement window is usually double-layer structure, the air layer between the glass effectively hinders the sound transmission, so the sound insulation effect is better than that of aluminum alloy sliding window.
Difference 3: Performance
The air tightness and water tightness of the windows are better than those of the sliding windows. The greater the moment resistance of the door and window profiles, the greater the resistance of the door and window members to wind pressure. The sectional area of casement window is generally small, but its main load-bearing members are usually assembled or vertical materials, which will be strengthened in the design process, so its wind pressure resistance performance is better. Generally speaking, the section section of push-pull window is relatively large, so its wind pressure resistance performance should be better. However, as long as a little in-depth stress analysis, it can be known that the main load-bearing member is often middle fan material, and its upper and lower stiles only rely on pulley to bear the horizontal wind load, so the wind pressure resistance performance is generally not ideal. The water tightness of doors and windows depends on the sealing effect of the opening part. The side opening windows are generally sealed with rubber strips, while the sliding windows are generally sealed with wool strips. The sealing effect of rubber strips is generally better than that of wool strips. In terms of air tightness, two-point lock or heaven and earth lock are widely used for locking and sealing of casement windows on the market, and the sealing effect is better. However, the sliding window is usually locked by hook lock or latch, and its sealing effect is not ideal. Therefore, the casement window is generally better than the sliding window in three aspects. This is also the reason why most high-end commercial and residential buildings choose to use casement windows.
