STATIONARY WINDOWS
Stationary windows, used alone or in combination
with double-hung or casement windows (fig. 4-26),
usually consist of a wood sash with a large single pane
of insulated glass. They are designed to provide light, as
well as be attractive, and are fastened permanently into
the frame. Because of their size (sometimes 6 to 8 feet
wide), stationary windows require a 1 3/4-inch-thick
sash to provide strength. This thickness is required
because of the thickness of the insulating glass.
Other types of stationary windows may be used
without a sash. The glass is set directly into rabbeted
frame members and held in place with stops. As with all
window-sash units, back puttying and face puttying of
the glass (with or without a stop) will assure moisture-
resistance windows (fig. 4-27).
GLASS
LEARNING OBJECTIVE: Upon completing
this section, you should be able to identify the
different types of glass, glazing materials, and
describe procedures for cutting, glazing, and
installing glass.
It is surprising how many types of glass and glass-
like materials are used in construction. Each has its own
characteristics, advantages, and best uses. In this
section, we’ll cover the various types of glass and
materials, and the methods used in assembling glass
features (“glazing”).
TYPES
The “Glass and Glazing” section of construction
specifications contains a wide range of materials. These
may include sheet glass, plate glass, heat- and
glare-reducing glass, insulating glass, tempered glass,
laminated glass, and various transparent or translucent

plastics. Also included may be ceramic-coated, cor-
rugated, figured, and silvered and other decorative glass.
Additional materials may include glazier’s points,
setting pads, glazing compounds, and other installation
materials.
Sheet/Window
Sheet or window glass is manufactured by the flat
or vertically drawn process. Because of the
manufacturing process, a wave or draw distortion runs
in one direction through the sheet. The degree of
distortion controls the usefulness of this type of glass.
For best appearance, window glass should be drawn
horizontally or parallel with the ground. To ensure this,
the width dimension is given first when you are
ordering.
Plate
Plate glass is similar to window and heavy-sheet
glass. The surface, rather than the composition or
thickness, is the distinguishing feature. Plate glass is
manufactured in a continuous ribbon and then cut into
large sheets. Both sides of the sheet are ground and
polished to a perfectly flat plane. Polished plate glass is
furnished in thicknesses or from 1/8 inch to 1 1/4 inches.
Thicknesses 5/16 inch and over are termed “heavy
polished plate.” Regular polished plate is available in
three qualities: silvering, mirror glazing, and glazing.
The glazing quality is generally used where ordinary
glazing is required. Heavy polished plate is generally
available in commercial quality only.
