The different types of windows include single-hung, sliding, casement, awning and hopper windows. These types of windows have varying prices, depending on their design, materials, functions, and significance to a particular environment.
In single-hung windows, the bottom sash moves up and down when opening or closing. Single-hung windows are more economical than the double-hung versions. In sliding windows, one sash or both slide forward and backwards horizontally when opening and closing.
A casement window comes with a hinge on the side to hold the sash as it swings out. The hinges fold in and out as the window opens or closes. An awning window connects to the window frame via hinges at the top section of the frame, and swings upwards. Awning windows provide ventilation, especially in bathrooms, while covering the elements of the room.
Hopper windows have hinges at the bottom, and move inwards when opening, and outwards when closing. Hopper windows help trap light into darker rooms, such as basements.
The type of frame and glass used to construct the particular window also influences the final price of the window. Some types of glass used on windows include clear, reflective and heat-absorbing versions. The types of frames include wood, aluminum, steel, vinyl and composite.
