Windows are openings shaped with glass to allow for the entrance of light within a space as well as the opportunity for views. As part of a building, windows can be found in a wall, roof, or door and are often able to be open to provide air flow. The earliest windows were unglazed with the admittance of light as its sole function, but over time windows were built to keep inhabitants safe from the natural elements. To enhance a window’s efficiency, type of glass, frame construction, and glazing should be considered although costs may increase.

What are the three main parts of a window?

A window consists of a frame, sash, and glass. The frame is the outer structure that supports the sash and glass. The sash is the movable part that holds the glass and can be opened and closed. The glass allows light to enter and is usually made of tempered or laminated safety glass.

When did using glass in windows first begin?

The first true glass windows, made from a single sheet of glass set in a frame, are believed to have been invented in the 1st century AD. These early windows were extremely expensive and were only used in the homes of the very wealthy. The widespread use of glass windows did not become practical until the development of plate glass making processes in the 19th century, which allowed for the production of larger sheets of glass at a lower cost.

Why are rooms required to have windows?

Most building codes require rooms to have windows for a variety of reasons. One reason is to provide a means of emergency egress in case of fire or other emergency. Windows also allow natural light and ventilation to enter the room, which can improve indoor air quality and the overall comfort of the space. In addition, windows can help to regulate the temperature of a room by allowing hot air to escape and cool air to enter.
