Some windows allow for better ventilation, and some types have a larger glass area for allowing in more daylight. Other designs may be easier to operate in hard to reach places. Any choice of window design will need to accommodate differing factors, depending on the house.
Some windows are hinged, while some types slide. A certain window type can be more common in traditional areas, like double hung windows are a classic design, while horizontal slider or awning windows are a more modern design.
Whatever type of a replacement window that you decide on for the appearance and effectiveness you require, frame construction matters as well. The type of glass that is combined with the frame to make up the window is vital too.
Also, whether you want double or triple paned glass fitted for better insulation (but bringing extra weight) may also affect your choice of window frame.
