The double hung and single hung windows have things in common, although they also have qualities and disadvantages unique to each one of them. It is therefore important to be able to differentiate the two before purchasing a single hung or double hung window. Before arriving at a decision on which among the two to select, you must first be certain whether it is a replacement window or a new construction window that your need requires. The latter requires installation prior to the exterior of the building being done, whereas the former is simply fitted in the space previously occupied by the old window that is going to be replaced. After choosing between replacement and new construction windows, you can then shift your attention to selecting either single or double hung.

Single Hung Window Double Hung Window

Two (2) separate sashes – one at the top and the other at the bottom, comprise a double hung window. These two sashes can function simultaneously by having two separate tracks on which the sashes can slide on in a vertical position. The top sash can be completely opened, when the bottom sash is completely shut. Alternately, the bottom sash may be completely opened when the upper sash is completely shut. Together, both sashes can only be half opened. Any which way it is opened, a double hung window is limited to an opening equivalent to one half of the total size it has. But some people may prefer this because the ventilation can be adjusted to suit your need. If the top sash alone is opened, it will only allow gentle winds to ventilate the room, and this will be directed on the upper part of the room. This protects any lightweight decors or fixtures in the room from being displaced. Ventilation while raining can likewise be achieved if the upper sash is only partially opened. This will cause the rain
water to bounce off instead of bouncing into the house.

But whereas the double hung window has sashes that are both movable, the single hung’s upper sash is immovable or permanently shut. Its lower sash has a vertical motion that either opens or shuts the window. The single hung window lacks the adjustable nature that a double hung window offers, but on the other hand it provides better insulation for a room since half of it is completely sealed. Only the movable portion is exposed to mishandling, misuse, or aging.

The single and double hung windows have supporting hardware in the form of springs or balances that serve to counter-balance the fixture, thereby causing it to remain in the position for which it was intended. All the single and double hung hardware have these common options, but there are some brands that offer an added advantage. The movable sashes can be moved slightly inward for easy cleaning of the inner as well as outer portion of the glass from the interior of the house or building. This feature can be particularly beneficial if the window cannot be easily reached from the exterior.
