The most important requirements for window structures.

The window is a design that is designed to protect the room from cold, wind, precipitation, dust and noise. In this case, the window must pass sunlight and be able to sometimes ventilate the room. Perhaps this is only part of the functions that the window performs, in fact, there are much more of them, because the window is also part of the building, which means that it should have a beautiful appearance and ideally fit under the architecture of the building.
