AWNING WINDOW

An awning window is hinged at the top. When opened, the sash projects out at an angle like "awning''. Hardware: A chain winder operator permits window to be opened or closed without removing screen.

Ventilation: Sashes can be left partially open during inclement weather giving controlled ventilation. Inside controls, such as a Venetian blind, can be used to direct the breeze downward if the sash is not fully opened.

View: Vertical divisions, where sashes meet, do not interfere with vision as much as the horizontal rails in double-hung windows since a person can look around a vertical obstruction easier than a horizontal one.

Remarks: Use of a chain winder makes window easy to open and close even when located above kitchen sink or furniture. Inside screens used with these windows are easy to change. Since the sash projects outwards, people are apt to bump into them.

Avoid placing walkways or play areas within arc of outswinging windows.

CASEMENT WINDOW

A casement window consist of a sash hinged at the side to swing outward. Two or more sashes, separated by a mullion, can be used in a frame.

Hardware: Window can be opened or closed by either a winder on the frame, or a handle on the sash. If winder pushes only the bottom part of the sash, the operation will strain tight-fitting sashes. Use barrel bolt on frame to hold sash tightly closed, two are recommended for tall sashes.

Ventilation: Outswinging window can scoop in air which would otherwise pass the opening - i.e., air moving parallel to wall surface. If wind direction is changeable, open only those sashes which catch breeze from right or left, depending on wind direction.

View: Vertical window divisions (457 mm to 762mm apart) interfere with the view, but are not as objectionable as horizontal divisions at eye level sometimes found in other types of windows.

Weathertightness: Weatherstripping is necessary.
