Window History
Some say the window got its start as a hole in a wall. But of course as time and mans understand of his needs progressed windows were covered with various material to shelter him from the elements. The shutter, a covering that could be opened and closed, came as the next major development. Eventually mullioned glass windows came about that both protected the residents and provided light. Paper and animal horns were also used for a time. As you may have guessed the Romans were the first to use glass for their windows. In Alexandria around 100 AD cast glass windows came on the scene. Not until the 17th century though did glass become common in homes. The glass making process still would have to come a long way before the full potential of the window with all its strength and beauty could be realized.What Purpose?

Types of Windows used Today
Common Double-hung sash window
The traditional window. Double hung windows give one great control of a rooms ventilation. They have an upper sash that slides down and a lower one that slides up. The two parts are not necessarily the same size. Springs, weights, or friction mechanisms help move and position the sash. With certain types, the sash can be manipulated for cleaning purposes. Nowadays, most new double-hung sash windows use spring balances to support the sashes, but traditionally, counterweights held in boxes either side of the window were used. These attached to the sashes using pulleys made with cords or chains.
