Single Hung Windows
What's the difference between single-hung and double-hung windows? Essentially, they are the same because they both have two panes, one above the other. However, only the bottom panes moves up and down on a single-hung, while both panes of a double hung slide vertically. Otherwise, they are commonly available in the same sizes and shapes. Both types of windows usually are held open by friction between the sash and the window frame, but both may use a spring mechanism instead to remain open. Many people also confuse single-hung windows with fixed windows, but fixed windows do not open at all.
Recent advances in materials and insulated glazing know-how have made single (and double-hung) windows much more energy efficient than they used to be. Combined with their simplicity and reduced cost, these improved energy benefits have helped to sustain their popularity. Both are almost automatically the preferred choice when exterior space is limited because both single- and double-hung windows open up instead of out. This makes them ideal for areas like walkways, porches, patios, and other high traffic areas that require exterior space to remain unobstructed. Finally, when replacing windows, either single- and double-hung windows are the obvious design choice when the original windows were of the vertical sliding variety. In both cases, the minimal amount of hardware necessary for a vertically sliding sash reduces the cost and complexity, which keeps maintenance costs low because of the limited number of moving parts. On the down side, vertically sliding windows have a tendency to leak ore air and water than projecting or hinged windows.
Benefits of Vertically Sliding Window
* Single-hung windows don't take up space when open.
* When it is important that the new windows maintain the appearance of the old windows, single-hung windows are often the optimal choice for retrofit and replacement projects.
* Modern single-hung windows are much more energy efficient than older models.
Single-hung windows are less expensive.
Screens can be mounted on the outside of the house.
Single Hung vs. Double Hung Windows
When comparing the two types, price can be the differentiator. The economic construction of single-hung windows makes them less expensive. Choosing single hung windows over double hung can save up to thirty percent on the original purchase price. However, you need to keep this savings in the proper perspective. When choosing between the two, it is important to compare the relatively minor savings of the original purchase price with the ultimate perceived value of your home when it comes time to sell it. Since the difference between their costs is relatively minimal, the value of the positive impact that double-hung windows have on a potential buyer may far outweigh the amount you saved on the initial purchase.
One of the big differences between the two types of windows is the amount of ventilation they afford and the increased flexibility and adaptability that double-hung provide. If you need increased airflow, opening the top and bottom improves circulation. In the summer, for example, you can open the bottom sash on the side of the house the breeze is coming from and the top sash on the opposite side to create natural cross-ventilation. Or if it's a windy day and you have things at sill level that will blow around, opening the just the top solves the problem. The biggest advantage to double hung is you can tilt both sashes in for cleaning. With single, cleaning the fixed pane is going to require a trip outside at best and performing a ballet between the shrubberies or dangling from a ladder at worst.

If you are looking for a traditional choice that won't set you back as much as most other window styles, single hung may be your best option. Single-hung windows are everywhere in new homes and old homes, alike, across the country. They come in a variety of styles to match your home, your needs, and your budget. With one fixed pane and one slider, single-hung windows are a simple, well-designed choice for any home and they can be used as replacements for all but the largest openings. If you are concerned with preserving the classic design of an older home, airflow isn't an issue, and there's simply no room for windows that open inward or out from the wall, a single-hung window could be the simplest and most economical solution for you.
