I was shocked when I learned why some window grilles are curved at the bottom – most people don’t know the real reason! 
You may have noticed some windows with grilles having a characteristic shape, with a “belly” at the bottom. Well, you can’t imagine what else they are used for, beyond home security.
They are found in different places. Their use varies depending on the needs of each owner:
- To place flower pots.
- For security against thieves.
- To install the air conditioning unit.
- For flowers.
Many believe that the curve was designed to accommodate flower pots, as it gives the plants more space. This view seems to dominate in Mediterranean countries as well as in Latin America.
For security
Others believe that these curved grilles prevent burglars. They are often found on ground-floor windows and help deter thieves.
The specific shape can also provide more space to secure objects.
For air conditioning
In urban areas like New York, some residents use the space for air conditioning units.
While this is possible, it depends on the size and configuration of the window.
According to experts, the truth is that these grilles can serve multiple purposes. They are primarily installed for security. However, their design can also accommodate flower pots.
In some cases, they can even hold air conditioning units, depending on the specific size of the window and installation.
