Buying skills for casement windows and sliding windows


There are many types of windows, but two of the most popular are casement windows and sliding windows. Both have their own advantages and disadvantages, so it's important to understand their differences before making a decision.



1. Difference in shape


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 appearance. The opening method of the sliding window is horizontal sliding, and its maximum opening area is 50% of the window, which is easy to occupy space, so it is more suitable for industrial buildings and rural-style buildings.


2. Performance difference


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


3. Appearance difference


Casement windows are very flexible and can be opened and closed freely, and are suitable for large-scale floor-to-ceiling windows and buildings with stricter requirements. Sliding windows can only push and pull sashes horizontally, so they are suitable for buildings with clear horizontal and vertical lines.


4. Difference in thermal insulation performance


Because the opening fan part of the casement window is locked and sealed by the heaven and earth lock, the sealing effect is very good. Most sliding windows use hook locks or latches to lock the sash, so the sealing effect is not as good as that of casement windows.


Why can't casement windows be used in buildings with more than seven floors?


1. For safety


It is not uncommon for the glass windows of high-rise buildings to be blown off and shattered by strong winds in the season of strong winds. Even the best quality windows are inevitably used improperly or negligently. This not only causes inconvenience to the lives of high-rise residents, but also directly A major threat to the safety of people's lives.


2. Specification requirements


The outward opening of the casement window opens outward, and the window sash is exposed to the wind, the sun and the rain, which is prone to fading, corrosion and damage; while the bay window of the casement window is suspended outside the wall, whether it is cleaning the window or changing the glass. It is inconvenient, and it is easy to make people dizzy and dangerous. In residential buildings, the 7th to 9th floors are middle and high-rise buildings, so no open casement windows are allowed above the 7th floor. Moreover, it will appear cluttered on the building facade, destroying the overall sense of the building's appearance.


What are the tips for window selection?


1. Which type of window to choose


The types of windows include casement, push-pull and fixed. In terms of sound insulation, the fixed window has good sound insulation, but this type of window is only suitable for places that do not need to be opened but have lighting needs; casement type. Compared with sliding windows, the sound insulation effect of casement windows is better than that of sliding windows. You can choose the appropriate window type according to your needs.


2. Look at the tightness of the windows


Tightness refers to the degree of sealing of the window, including the sealing of the glass and the frame, the sealing of the frame and the frame after closing the window, and the sealing of the window and the wall after installation, which together affect the sealing performance of the window. It is the sealing strip that determines the sealing degree of the window. At present, the sealing strips on the market are mainly wool sealing strips and rubber sealing strips. They each have their own shortcomings. The wool sealing strip is easy to depilate after being used for a long time, which greatly reduces the sealing effect. The rubber sealing strip is easy to harden and age after being exposed to wind, sun and rain, which also reduces its sealing effect. Therefore, everyone should choose according to the actual situation.
