Windows are not all built alike. You do have a choice when it comes to style and look of the windows inside your house. The best situation for choosing window styles is when you are building a new house, but many existing windows can be easily replaced with an upgraded style.
Fixed Pane Windows
Fixed pane windows are those windows that cannot be opened and therefore provide no ventilation advantages. Think windows in a high-rise building when you think fixed pane windows, but understand that you can introduce them into your residence if you so desire. Fixed-pane windows are available in an array of styles and sizes and you can probably find one to match any existing windows that can be opened.
Casement windows usually swing outward and often feature an interior screen. It is possible to have casement windows that open inward however. Depending on where you are buying your windows, you may need to special order casement windows that open inward. Casement windows come with hinges that open to either side so you can take advantage of any tradewinds that blow regularly past your home.
Like sliding doors, sliding windows run in a track that allows you to slide one half open and closed while the other half stays perpetually closed. You may find sliding windows the most affordable option if you are looking to change your current window situation. Think of a traditional double-hung window that has been turned on its side to open sideways. Of course, since only half a slider window can be opened, you may not get as much air ventilation as you want. The upside is that sliding windows are easy to disassemble for cleaning purposes.
Single Hung Windows
If you look directly at a single hung window, you can easily mistake it for a double-hung window. The only real difference is that with a single hung window, only the bottom sash opens. This makes them, as you might expect, cheaper than double hung windows.
No, not a nickname for super-wimp Nancy Pelosi, although it does come close. Jalousie windows feature louvered panes of glass that open courtesy of a crank. The good thing about jalousie windows is that they offer magnificent ventilation properties. The bad thing is that each individual pane of glass represent a joint that must be kept sealed to avoid escaping heat or cold. Jalousie windows are also not the best choice for those living in high-crime areas as they can be easily broken into.
