window type - a. A window that can be left open in the rain

Back 1

projected windows such as the awning window or hopper window (more common in commercial than residential) or tilt/turn windows which have elaborate but concealed hardware that allows each window to be operated as either a casement or a hopper.

Front 2

b. A window that must induce the maximum possible ventilation from passing breezes

Back 2

casement windows assist in catching passing breezes and inducing ventilation through the building or the tilt/turn window when it is operated as a casement.

Front 3

c. A window in a high-rise office building

Back 3

Window types that are used almost exclusively in commercial and institutional work include horizontally and vertically pivoting windows and side-hinged inswinging and top-hinged inswinging windows. These types all allow for inside washing of exterior glass surfaces. Because they project inward rather than outward, they are much less subject to the damage than casement windows in the case of high winds. To further limit wind damage, windows in tall buildings are often fitted with simple devices that limit the extent to which they can be opened. In most tall buildings, if the windows operate at all, they are not meant to be used for ventilation unless the building’s air conditioning system is inoperative.

Front 5
