It’s the peak season for home decoration again! Which is better, outward-opening or inward opening windows?
This problem has also troubled many property owners. I’m just afraid of making the wrong choice.
Not only will it not be user-friendly, but there might even be security risks.
Both of these are commonly used window types in the home decoration market. But which one is better? Can we install whatever we want?
01The difference between outward-opening or inward opening windows
Outward-opening window
Advantages
It does not occupy indoor space.
The window sash opens outward, which does not occupy indoor space, poses no risk of corner collision, and does not affect the use of curtains.
Disadvantage
The security is relatively low.
The window sash opens outward, and people need to lean out when opening or closing the window, which is particularly dangerous for children and the elderly.
There is a risk that the window sash may fall outside, so hinges and anti-fall ropes need to be installed.
It’s easy for mosquitoes to get in.
Screens are usually installed indoors. When opening the window, the screen needs to be opened first.
During the process of opening the window, mosquitoes can enter the room.
Outward-opening Windows open outward.
The window sashes are exposed to wind, sun and rain, making them prone to fading, corrosion and damage.
Inward-opening window
Advantages
High security.
There is no need to lean out during the process of opening and closing the window, and there is no risk of the window sash falling outside.
Good sealing performance.
Closing the Windows can effectively reduce noise and insulate heat.
Optimize ventilation performance.
When in the internal ventilation state, natural ventilation can be achieved, allowing for safe ventilation and air exchange even on windy and rainy days.
Disadvantage
Occupy indoor space.
There is a risk of people bumping into corners during the activity.
Protruding window sashes can affect the use of curtains.
02How to choose outward-opening or inward opening windows
Whether to choose an inward-opening window or an outward-opening window also requires careful consideration.
It mainly depends on the local climate conditions, the height of the floor, and the size of the opening sash.
Climatic conditions
In cold regions, inward-opening Windows are preferred as their sealing performance is more easily guaranteed.
In tropical or subtropical regions, outward-opening Windows are more common.
The outward-opening design facilitates the rapid discharge of hot and humid air, enhancing ventilation efficiency.
Floor height
The basic principle is a high internal opening and a low external opening.
If the floor is relatively low, such as a self-built house or a villa, it is fine to have outward-opening Windows.
For floors above the 7th, for safety reasons, it is recommended to consider inward-opening Windows.
The size of the opening fan
The basic principle is that large opening fans should be designed for inward opening and small opening fans for outward opening.
If you want a larger opening sash, it is recommended to give priority to inward-opening Windows.
First of all, there are certain size restrictions on outward-opening Windows.They cannot be made too large. The larger the window, the heavier it is, and the greater the pressure on the hardware, which will increase the risk of falling.
Secondly, the length of a human arm is generally 65 centimeters. If the window area is too large, when we reach out to close it, we may have to stand on tiptoe and exert a little force, which can easily cause an unstable center of gravity. This is very dangerous
Overall, when choosing an inward-opening window, we should make the decision based on the specific region, floor, and the size of the opening sash.
