Window

Window is a transparent or translucent opening in a wall, door, roof or vehicle that allows the passage of light and, if not closed or sealed, air and sound. Windows are usually glazed or covered in some other transparent or translucent material like a float glass. Windows are held in place by frames, which prevent them from collapsing in while allowing light to pass through.

Types of Windows

There are several types of windows, each with its own unique design and function. Some of the most common types include:

• Casement Window: This type of window is hinged at the side and opens outward. It provides a clear view to the outdoors and can be opened and closed with a crank, lever, or handle.

• Double-Hung Window: This window has two sashes that slide vertically up and down in the frame. They can open wide from either the top or the bottom, but they remain inside the frame so they don't protrude out to the exterior or interior of the house.

• Picture Window: These windows are large and do not open, allowing for an unobstructed view of the outdoors.

• Transom Window: A transom window is a narrow window that can be either operable to let in air or fixed for decorative purposes. They're typically used over doors or windows to let in more light.

History

The use of windows dates back to ancient times, with the earliest examples found in Roman architecture. The Romans were the first to use glass for windows, a technology likely first produced in Roman Egypt.
