Double Hung Window Basics
If you are looking for replacement windows in fairly standard sizes, one of the most common styles you will find is the double-hung window. These feature two panes of glass – each in a separate frame or sash. With a true double-hung window, the bottom pane and top pane can both slide up or down independently of one another.
Some cheaper models only allow movement of the bottom pane. In these cases, there is generally only a screen on the bottom half of the window. Either style works equally well to ventilate your home with fresh air and reduce the accumulation of indoor air pollutants.
These windows may be placed on either side of a larger “picture” window that doesn’t open. That way, the room has a view and plenty of sunlight along with a nice breeze. Double hung windows that open easily may also play a role in an emergency fire exit strategy.
Compression weather-stripping, springs, or counterweights are used to hold the open sash firmly in the desired position. If these components become worn or damaged, they need to be repaired or replaced. Otherwise, the open window sash may slide down into the sill forcefully enough to cause the pane to shatter.
Double hung windows can be purchased with vinyl, wood or metal frames. Energy efficient styles often feature double paned glass and UV radiation protection. Installing replacement windows that are the same size as your current windows is relatively easy. However, making sure the seal around the jambs and sill is airtight takes some attention to detail. Always read the manufacturer’s warranty before attempting a DIY window replacement to make sure you aren’t voiding your coverage.
