Windows are available in a variety of designs and sizes. There are differences in opening mechanisms and structure, as well as the type of glass they contain. The following pages contain information on replacing and renovating windows, as well as installing catches, shutters, and glazing. Common minor repairs for windows are shown here.
TYPES OF WINDOWS
There are several different types of windows. Traditionally, most windows were side-hinged windows, referred to as casements, and sliding sash windows. New opening mechanisms such as friction and pivot hinges (opposite) are increasingly popular. Window materials, shapes, and sizes vary considerably, as does terminology, so you should read your manufacturer’s literature carefully. Replacement windows for older homes often need to be custom-built to your requirements.
Commonly, the material and mechanism of a replacement window is chosen to match the originals. There are some exceptions -- new sash windows, for example, will often be equipped with modern spiral balances, although they look the same as original lead counterweight versions . If you are replacing all the windows in your property, or building a new home, then take time to consider energy-efficient products such as double and even triple glazing. Frames may have a sill attached, an optional sill, or none at all. If your old frame has a sill attached, make sure your replacement has one.
Common types of windows:
Side-hinged casement and sliding sash windows are still very popular, although pivot and awning windows are becoming common. There are variations on these themes, with each type of window made in many different sizes, shapes, and styles.
Custom casement screened window: Custom windows offer you a selection of sizes and styles that can meet any needs. When you order custom windows, you have options to include special glass, lites, or other features like this window screen. (Side swings out; Screen fabric rolls dawn)
Awning window: Butt hinges are used along the top edge of older designs; newer awning windows use friction hinges at either end of the top edge (see below). Both arrangements allow the bottom edge of the window to swing open.
TYPES OF WINDOW MECHANISMS
There are several different mechanisms used to open windows. How a window opens can have implications on how space in a room is used -- clearance may be needed to enable you to open some windows. Some types, known as “tilt-and-turn windows,” have combination hinges and can open vertically or horizontally, depending on how the handle is operated. The opening mechanism of an existing window can't normally be changed.
Weights and balances: Vertically sliding sashes use lead weights or modern spiral balances to hold them in position. Horizontally-sliding windows run on tracks, similar to those for patio doors.
Pivots: Tilting casements pivot halfway down each side, or midway along the top and bottom of the frame. The pivots are designed to hold the window in any position.
Friction hinge: These are used on awning and casement windows. The hinges are at either end of the hinged edge, rather than along the edge itself. The “friction” holds the window in any open position.
