There several different types of windows.  This is just a primer on the types of windows out there:

1) Casement Window

The Good – Casement windows open outward for light, fresh air and side breezes. They’re tightly sealed for energy efficiency and great for hard-to-reach places, such as over sinks and appliances in the kitchen.

The Bad – If you’re moving into an older home, check on the stability of your casement hinges and hardware. Though casements are usually tough to break into, faulty or rusty hardware increases your risk factor. During windy weather, they are hard to open and close.

2) Awning Window

The Good – Awning windows are designed to provide light and breeze. They’re great for bedrooms and other areas that need to maintain privacy but still let some light in. Awnings can be opened slightly to allow ventilation.

The Bad – Screens for awning windows are set on the inside, which can mean that all the dirt and dust that normally falls into the sash makes its way onto your floors instead.

3) Double Hung Window

The Good – Double hung windows are chosen for their unique style, ease of access and superior ventilation capabilities. The top of the window can be opened while the bottom remains closed.  Double hung windows can go practically anywhere in your home. They’re perfect for kitchens, offices and bedrooms.

The Bad - Double hung windows tend to leak more air than other windows. And keep in mind that only half of this window opens up, whereas different types can open completely.  Tend to a problem in older homes.

4) Single Hung Window

The Good – Single hung windows are chosen for their unique style, ease of access and superior ventilation capabilities. Single hung windows can go practically anywhere in your home. They’re perfect for kitchens, offices and bedrooms.

The Bad - Single hung windows leak less air than double hung windows. And keep in mind that only half of this window opens up, whereas different types can open completely.

5) Picture Window

The Good – Picture windows create unobstructed views of the outdoors. They’re best in areas where ventilation isn’t a big concern. Think about installing them high on the walls of dark rooms and hallways for infinitely better lighting. In combination with patio doors or open-and-close windows, picture windows bring the perfect balance of light and ventilation.

The Bad – These windows are for looks only. And the large expanse of glass can make them more vulnerable to breakage.  You cannot open these windows.

6) Bay or Bow Window

The Good – Bay windows create an open, peaceful feel indoors. Their multiple views allow light to stream in from different angles. Plus, the sides of the window can be opened for air circulation. Bay windows dress up any home with uniqueness and style. Replacing a flat window with a bay can completely change the amount of light that room receives. They’re primarily used for kitchens, but can also add character to family rooms and master bedrooms.

The Bad – Only the sides of bay windows open and typically don’t come with screens, so incoming pests could be a problem.  Also, these windows tend to be very expensive.
