Having a basic understanding of double hung windows will help when learning how to replace a sash cord. There are two sashes on a double hung window, the upper and lower. The framework that holds the glass in place is the sash. The two sashes slide up and down in the window frame. The jambs are the sides of the frame. Sash weights are heavy oblong shaped pieces of metal that connect to a rope-and-pulley system. They sit in a cavity behind the jambs. The windows are easy to open due to the counterbalance the weights provide.

It was seven-ish and I was sitting in a pleasant-enough room overlooking the front doorway to the pub above which I had just moved in. The pub was the Pig and Whistle on Soi 7 in Pattaya. Across the lane was a large hole, which they were hoping to build a hotel in and next door to that, right opposite me, was a tiny bar with one lady sitting on a stool outside it. Not that there was a wall there, it was open on two sides. The Soi was nice and peaceful, I thought. I also thought that I might go and sit in that little bar and talk to that lady, if my friend was late, because I would definitely see him arrive from two metres away, the width of the Soi.

When tracing the history of sash windows one is also tracing the history of our civilization. This window, also called a hung sash window, had sashes, another name for one or more movable panels. Pulleys, springs and balances to move the panels and allow ventilation operated these panels.
