Whether in the renovation of a new house or an old window, homeowners always hesitate about how to choose the window opening method? I feel like my head is very big. In reality, it is necessary for us to understand the common ways of opening doors and windows. So now let's discuss the two categories of sliding windows and flat windows together.

[--- Sliding Window ---]

Sliding windows are divided into two types based on the sliding direction: horizontal sliding windows and vertical sliding windows. Horizontal sliding windows require track grooves to be placed on top of the window sash, while vertical sliding windows should have pulleys and balancing measures. Windows that can be pushed left and right through single, double, or multiple windows.

Performance advantages of sliding windows:

1. The window does not occupy additional space in its on/off state, has a simple structure, and allows for easy selection of fan positions and ventilation openings.

2. Easy to install and use screen windows and curtains

3. Easy operation and long service life

Disadvantages of sliding windows:

1. The maximum opening can only reach 50% of the maximum area

2. Poor airtightness when closed

3. Due to the storm, it can only be closed and the ventilation performance is poor.

Suggestions for scene suitability of sliding windows

Due to the performance of sliding windows, they are suitable for small home spaces and are recommended for use in rural buildings with quiet environments, less rainfall, and fresh spaces, as well as in environments and areas with low requirements for window sealing, sound insulation, and viewing.

[--- Side hung window ---]

There are many ways to open a casement window, such as opening inside out, tilting inside out, or hanging outside. The difference between the four opening methods mainly lies in the ventilation effect.

1、 External opening and downward suspension

Open and hang the handle of the operating fan, and then drive the hardware accessory transmission to move relative to each other; Use the outward opening or outward tilting of the window to achieve ventilation and air exchange at an angle of 15-30 degrees.

Its performance advantages:

1. Good ventilation performance, good sound insulation and heat insulation performance when closed

2. Strong security and anti-theft capabilities

3. Highly practical, occupying less indoor space, and providing good rain protection when in the open state

Performance drawbacks:

Poor safety performance, requiring the use of anti fall ropes; The hardware accessories used are correct, so the price is relatively expensive compared to internal opening and inverted.

Usage suggestion:

The most commonly used places for this type of window are mainly in some engineering projects, such as hospitals, hotels, apartments, etc. Home decoration is suitable for areas with low floors and strong winds; If there is a fresh air system at home, it is best to equip the external fan with an anti fall rope device.

2、 Internally open and internally inverted

The inward opening method generally exists simultaneously with the inward opening window and is an additional function of the inward opening window. Realize inward opening or inward tilting through different connection methods of hardware components; When the window is inverted, a gap of about ten centimeters can be opened from above, and the opened part is suspended indoors. When the window is opened upside down, the wind enters the room from the top of the window, making it softer and avoiding discomfort caused by sleeping with the window open. Suitable for the current weather conditions where the temperature is unpredictable, with cold or hot weather when the windows are open.

Its performance advantages:

1. Open the top of the wind to enter the room, with good ventilation and softer ventilation

2. Enhance security performance and strong anti-theft capability

3. More sound and heat insulation, rain and wind resistance, good sealing performance, and good air tightness

4. Easy to clean and tidy up

5. Environmental protection and energy conservation

Performance drawbacks:

1. Small window width and limited field of view;

2. When the inner window is opened, it will occupy some of the indoor space, and the window corners are easy to touch, making it impossible to close the curtains when opened;

When the external window is opened, it has a large wind area and is prone to damage. In some places, it is prohibited to install external windows at high altitudes.

Usage suggestion:

1. Suitable for areas with high levels of dust, noise, and rainfall;

2. Areas with high frequency of air conditioning usage can save energy and reduce costs;

3. Pay attention to the environment of the space, such as the living room, bedroom, study, etc.

4. Middle and low rise residential buildings near the road can be equipped with insulated glass for better sound insulation effect;

3、 Internal and external casement windows (with gauze fan inside and glass fan outside)

Internal and external casement windows are easy to clean, have good ventilation performance, good sealing performance, good water tightness performance, good sound insulation, heat insulation, wind pressure resistance, and energy-saving insulation effects. Easy to use and does not occupy indoor space. However, in extremely severe typhoon weather, there may be a risk of window falling, so many high-rise buildings prohibit external windows (to avoid blowing off window sashes and hitting people)

Lidu Doors and Windows Editor's Summary and Suggestions

By using different opening methods, the ventilation effect also varies

My personal opinion is: sliding window, casement window>lower hanging window (inward opening and inward tilting)>upper hanging window (outward opening and upward hanging)

So each opening method is different, choosing the one that suits oneself is the best; Because each opening method has its own advantages and disadvantages; Through the above analysis and communication, compared to most users, how to choose and match doors and windows that are suitable for themselves. Of course, choosing doors and windows is not only about the opening method, because many low-priced ones on the market often have great safety performance, especially those with flat windows and hanging down because they are all achieved through accessories. Therefore, we hope that homeowners will not cause safety problems due to the desire for cheap prices.
