Double Hung Windows

Advantages
- Because they are held firmly in place by the window frame, double hung windows rarely warp or rot.
- Unless there painted shut, double hung windows are simple to open and close as long as you can stand directly adjacent to them for a good leverage.
- Relatively little air leakage occurs around the edges, even when the sashes are not whether stripped.
- They can be cleaned from the inside if the sash is removable. The older models had pulleys and weights suspended within the wall to help the window open and close-they had to be cleaned from the outside. Some modern double hung window sashes can be tilted out of their styles, to the inside, for convenient cleaning and replacement.
Disadvantages
- If you have to reach over-the-counter or piece of furniture to open and close them, double hung windows will be a difficult window to operate and shouldn't be used.
- These windows can never open to more than half of their total area.
- Even when they're open only inch or 2 double hung windows are likely to admit hard driven rain.
- If the sashes are removable, the only way to clean them is from the outside-with the latter when they're located on the 2nd story levels.
