Push and pull window: there are two types: left and right, up and down. Sliding window has the advantages of not occupying indoor space, beautiful appearance, economical price and good sealing. Adopt high-grade slide rail, push gently, open flexibly. With large glass, the lighting in the room is increased and the overall shape of the building is improved. The window sash is in good stress state and not easy to damage, but the ventilation area is limited. So, today, we will introduce the features of push-pull window and flat window.

1. appearance comparison

The difference between the flat window and push-pull window is mainly in the matching with the overall style of the building. The open window can make any line facade effect because of its flexibility in dividing the grid. For the large divided floor windows, the opening fan only accounts for a small part of the whole window, so it is more suitable for the high-grade buildings with strict overall effect requirements, especially in line with the large division, spacious and bright, good penetration effect pursued by the architect A building with a smooth appearance.

The sliding window can only be pushed horizontally because of its opening position, so it is difficult to match the fixed glass with large divisions. Generally, it is suitable for the opening workshop with clear vertical lines or rural family buildings.

2. performance comparison

In the three performance of doors and windows (wind pressure resistance, water tightness, air tightness), flat windows are generally better than push-pull windows. The wind pressure resistance of doors and windows depends on the resistance moment of main members of doors and windows. The larger the section of profiles, the larger the resistance moment is, but not fully proportional.

The section of the general profile of the flat window is small, but the main force-bearing members are usually made of collage or vertical materials. These main stress-bearing members will be strengthened correspondingly in the design process, so the wind pressure resistance performance is better.

The section of sliding window profile is generally large, so it should be better in wind pressure resistance. However, as long as a little in-depth stress analysis, it is known that the main stress member is usually medium fan material, and the upper and lower stiles only rely on the pulley to bear the wind load in the horizontal direction, 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 flat windows are generally sealed by rubber strips, while sliding windows are generally sealed by wool strips. The sealing effect of rubber strips is generally better than that of the wool strip.

In terms of air tightness, the open fan of flat window on the market is mostly sealed by two-point lock or heaven and earth lock, and the sealing effect is better. Generally, the sliding window is locked by hook lock or bump lock, and its sealing effect is not ideal.

So flat windows are generally better than push and pull windows in three aspects of sexual energy. This is why most high-end commercial and residential buildings choose to use flat windows.

3. comparison of heat preservation

In terms of heat preservation performance, the flat window is generally sealed by sealant strip on the market, while sliding window is generally sealed by wool strip, and the sealing effect of rubber strip is generally better than that of wool strip. The two-point lock or the heaven and earth lock are used for locking sealing in the open fan of the flat window, and the sealing effect is better. Generally, the sliding window is locked by hook lock or bump lock, and its sealing effect is not ideal.

4. price comparison

The price of the same grade flat window and push-pull window is not different, flat window to slightly higher than push-pull window. The price of ordinary flat aluminum alloy windows is 200-350 yuan / m2, the price of medium window is 450-600 yuan / m2, and the price of high-grade flat window is generally above 800 yuan / m2. The common sliding door window is generally 150-300 yuan / m2, the middle grade aluminum alloy sliding window is 350-500 yuan / m2, and the high-grade sliding door window is more than 600 yuan / m2.

5. process

In the process and manufacture, the sliding window is generally simple in structure and has no special requirements for the equipment, so it is processed and manufactured in a small workshop of small saw; The flat window adopts the thick aluminum alloy corner 45 ~ The connection requires better "angle striker" and "double cutting saw king" to produce excellent aluminum alloy flat window.
