What is a Window?

A window is a hole in a wall or roof through which light and air can enter a building. Windows have been used since ancient times to allow in light and life-giving breezes

In this article we will discuss what a window is, the difference between a picture window and a sliding door, and maybe even make you laugh

What Is A Window

A window is an opening in a building that allows light, air, and sometimes water to enter. They are also known as portholes or openings because they resemble one of these items. The term "window" may refer to any type of opening in the body of a building that allows for the entry of exterior elements. Some common examples include doors, skylights, vent pipes (for ventilation), and even chimneys when they are located on top of buildings. Windows are also referred to as "portholes" because they look like portholes on ships or submarines

The Difference Between A Picture Window And A Sliding Doo

Picture windows were invented during the Renaissance period (circa 1400-1600). These windows allowed light into rooms from outside without letting any heat out during cold winter months
