Single-Hung Windows vs. Picture Windows

Single-hung windows are often the standard window choice for new construction, whether it be a house, apartment building, or offices. These windows are arranged vertically with two square sashes, one on the top half of the window and the other underneath. In a single-hung window, the bottom sash is the only one that can move, and the upper sash remains fixed. There are also double-hung windows with a design that allows both of the sashes to move and overlap in the center. Single-hung windows are used more frequently because they are typically cheaper than many other styles, including double-hung.

Picture windows are a common style for large openings. They are immovable windows that are entirely inoperable since they do not open or closed. That is why picture windows can also be called "fixed windows." Picture windows can be used alone, in combination with other picture windows, or with other window styles.

Are Single-Hung Windows More Energy-Efficient Than Picture Windows?

Single-hung windows are not more energy-efficient than picture windows. Since picture windows are completely fixed, they don't have any moving parts and are completely weathertight. 

Compared to picture windows, the single-hung style is not very energy-efficient because it can never fully seal. The sash in hung windows needs space to move up and down along the window jamb, it also needs some wiggle room to remove the sash for cleaning, maintenance, or repairs. An extremely weathertight fit would hinder the sash's movement. On another note, single-hung windows do tend to be more energy-efficient than their double-hung counterparts because they have fewer moving parts. While a single-hung window has one moving sash, the double-hung unit has two. 

Should I Get Single-Hung or Picture Windows for My Home?

These two windows are very different. Those differences often help new buyers choose which will suit their homes better. First, it helps to carefully examine the areas that you need the windows in since you might want or need a mix of both. Next, figure out your priorities and the aesthetic you want for the exterior of your home. Finally, examine the characteristics of the pros and cons to make your final decision.
