For many homeowners, double hung windows represent the more traditional window choice and are very common on older homes in the eastern USA. A double hung window is made up of two sashes that hang one above the other.

When you need some fresh air indoors, the two sashes slide vertically past one another to open (only the bottom sash slides up in a single hung window - the top one is fixed). You can choose between opening them just a tiny bit, or up to half the size of the window.

These windows with dual sashes often now feature tilt-in sashes, which means the outer surfaces of the windowpanes can easily be cleaned from the inside. And dual windows like these allow an insect screen to be put in position either on the inside or outside of the window frame.

A Vertical Slider

For openings more vertical than wide, double hung type windows can be made larger than hinged windows like the casement style. This means they can be less costly for your budget as you can often buy one larger double hung type instead of two smaller casement windows.

However their sliding seals are less efficient at stopping air leakage than hinged windows.

The double hung style and other sliding windows can be used in combinations, and because they are not hinged there’s no problem about external clearance. However, they are not recommended for places where it is hard to reach the window to open it (like over a kitchen sink).

Though available in different materials, homeowners who love the appearance of wood indoors will often install this type of window. As the dual sash style means more wood is on view to admire, but this does mean a bit less glass of course.
