Selection of broken bridge sliding window and broken bridge casement window

Sliding and casement are different in the case of using the same glass and accessories. The following is a detailed description of the appearance, performance and function of the doors and windows.

First: the appearance of comparison

The main difference between the broken aluminum casement window and the broken bridge aluminum sliding window is the matching of the building body style.

Broken bridge aluminum casement window is more flexible because of its divisional space, it can make any line facade effect, and for the large-divided floor-to-ceiling window, the opening fan only occupies a small part of the whole window, so It is more suitable for high-end real estates with strict requirements on the overall effect of the building, especially in line with the large division, large and bright, transparent and transparent appearance of the architects.

The aluminum sliding window of the broken bridge can only be horizontally pushed and pulled because of its open fan position, so it is difficult to match the fixed glass of the large division. Generally, it is more suitable for the opening factory or rural family building with more horizontal and vertical lines.


Second: the resistance to wind pressure comparison

The wind-resistant performance of doors and windows depends on the resistance moment of the main force-receiving rod of the door and window. The larger the section of the profile, the larger the resistance moment is, but not completely proportional.


The aluminum alloy casement window of the broken bridge has a small section of the profile, but the main force member is a piece of material or a vertical material. These main force members are strengthened in the design process, so the wind pressure resistance is Good performance.

The section of the aluminum sliding window profile of the broken bridge is generally large. It is reasonable to say that its wind pressure resistance performance should be better, but as long as the analysis of the force is deepened, the main force rod is often the middle fan material, and the upper and lower jaws are The wind load in the horizontal direction is only supported by the pulley, and the wind pressure resistance performance is generally not ideal.


Third: water tightness comparison

The watertightness of the doors and windows depends on the sealing effect of the opening parts. The aluminum casement windows of the broken bridges are generally sealed by rubber strips, while the aluminum sliding windows of the broken bridges are generally sealed with tops, and the sealing effect of the rubber strips is generally superior to the tops sealing.


Fourth: air tightness comparison

In terms of air tightness, the opening fan parts of the broken aluminum casement window on the market currently use a two-point lock or a heaven and earth lock for locking sealing, and the sealing effect is better.

The aluminum sliding window of the broken bridge is generally locked by a hook or a lock, and the sealing effect is not ideal.

Therefore, the aluminum alloy casement window is generally better than the broken aluminum sash window in terms of three performances. This is why most high-end commercial and residential buildings have chosen to use broken aluminum casement windows.


Five: process comparison

In the processing and production, the aluminum sliding window of the broken bridge is generally simple in structure and has no special requirements on the equipment, so it is convenient for small workshop or on-site processing;

Due to the fact that the window sash of the broken bridge is generally connected by aluminum code, it is necessary to have a good angle horn to produce an excellent aluminum alloy casement window.

Six: functional comparison

In terms of the function, the broken aluminum sliding window is favored by the majority of users because of its flexible opening and convenient operation.

In contrast, the aluminum casement window of the broken bridge is generally hinged (hinge) connection, and the opening is generally opened by a handle, and the sliding window is often not flexible in operation.
