2. Good ventilation

Secondly, the ventilation of the casement window is also very good. Because of the good sealing performance, the casement window has good functions such as sound insulation, heat preservation, and impermeability. When the casement window is operated, it is also divided into two ways: inward opening and outward opening. The advantage of inward opening is that it is convenient for scrubbing, and the feature of outward opening is that it does not occupy indoor space.

2. The outward opening type is easy to be damaged

If you choose the outward-opening type, it is easy to be damaged when there is a strong wind, such as if it is not fixed, the glass is damaged, or the window sash is dropped directly, it is easy to cause accidents, and it is easy to rust and break after a long time.

1. Aluminum alloy profiles are connected in different ways

The difference between the non-broken bridge window and the broken bridge window is that the broken bridge window uses nylon strip PA66 to connect two aluminum alloy profiles.

2. The heat insulation effect is different

Broken bridge windows have the function of heat insulation, and everyone knows that aluminum alloy profiles have the function of heat conduction. The non-broken bridge window spreads through the aluminum profile in summer, and the heat quickly enters the house.

3. The insulation effect is different

The broken bridge window prevents the indoor temperature from being transmitted to the outside in the cold winter, and has a certain thermal insulation effect, while the non-broken bridge window does not have the thermal insulation function.

4. The thickness of the window wall is different

The national standard wall thickness of broken bridge series windows is 1.4, and the wall thickness of non-broken bridge series broken bridge windows is about 1.0-1.2. Uneven distribution.

5. The sound insulation effect is different

The thermal insulation strip of the broken bridge window also has the effect of blocking external noise, while the non-broken bridge window does not have this effect.

Which is better, casement windows or sliding windows

1. Different shapes

From the perspective of appearance, casement windows have smooth lines, good transparency, and can open the sash to the maximum extent, so casement windows are very suitable for buildings with high lighting and smooth shapes.

2. Different performance

In terms of performance, casement windows and sliding windows are also different. Casement windows are made of different materials, so their wind resistance, water tightness, and air tightness are better than sliding windows, and they are generally more suitable for use in high-rise buildings. .

3. The appearance is different

The casement window has very good flexibility and can be opened and closed freely. It is suitable for large-frame floor-to-ceiling windows and buildings with strict requirements. Sliding windows can only push and pull the sash horizontally, so they are suitable for buildings with clear horizontal and vertical lines.

4. Different thermal insulation properties

From the perspective of thermal insulation performance, because the opening fan of the casement window is locked and sealed with a sky and earth lock, the sealing effect is very good. Most of the sliding windows use hook locks or latches to lock the sash, so the sealing effect is not as good as that of casement windows.
