– fixed sash - stationary glass unit
Window Types - Styles Additional and special condition types:
– Combination types - mixture of types together– Bay - angle projection– Bow - curved projection– Box - 90 degree projection– Skylight and Roof windows
Window Types - Materials
Wood - type of wood may differ inside/outside Steel - commonly used in commercial buildings Aluminum - commonly 6063-T5
– 6063 = aluminum alloy– T5 = a type of heat treatment
Vinyl/wood covered vinyl Glazing channels - holds the glass
– 3/16”, 7/32”, 1/4” single glazing– 1/2”, 5/8” double glazing (insulating)
Casement Window hinged at
jamb section
swing in or out
max ventilation
Horizontal Sliding Window one/both
sections movable
sections typically removable
horizontal arrow denotes sliding action also an “X”
Double (Single) Hung Windows one/both sections
movable sections typically
removable vertical arrow
denotes sliding action
Awning and Hopper Windows
Both have horizontal hinging
Awning hinges at the top
Hopper hinges at the bottom
Louvered/Jalousie Windows
•The individual panes allow good ventilation
Bow Window
Designed about an arc
Many configurations
Bay Windows More boxy than the
Bow window Angles of
projection at normally 30, 45, 60 degrees
Amount of projection varies
Skylights/Roof Windows
•Allows light and ventilation through the roof
Fixed/Picture Window No ventilation Custom built frame for different sizes and shapes Also double glazed
Fixed Window Detail Pictorial•Jamb section custom milled
•Shape and size may vary
Detailing Windows in Wood Construction
Usually purchased as a unit/assembly Custom sizes/combinations easily available Align details with each other: head, jamb, & sill Details similar to door
– window action is not important in detail, but may effect the detail
– weatherproofing & installation are important– detail from window frame outward
Head Detail (wood) with Pictorial
Jamb Detail (wood)
Note that details call out weatherproofing (caulking) & show trim size callouts
Sill Detail (wood) with Pictorial

Drawing ExerciseWood Window Detail
Draft the elevation of a 5040 (W x H) window, 1/2” = 1’-0” at the top of the sheet, details will be added to bottom
Extend the sill so more of the wall is shown below the window sill
Give notations to coordinate sections with detail Draft the brick to proper size showing the 3/8” joints Bricks at window sill are turned on edge and sloped (5
degrees), overhang is 1 1/2” on the underneath side
