Double Hung Windows


double_hung
These are the most common Windows found in construction today. The double hung window has 2 sashes or pains that slide up and down in channels or tracts called styles. As a rule, the sashes are the same size; but in some cases the bottom sash is taller than the top sash. The 2 sections are held in place by either springs or friction. If by friction it's a sign of a good tight fit.

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.
