Window Details (Wood)

Window Assembly

Finished window assembly depends on:– architectural design of structure– region of country/climate– material of structure– type of window

Detailers must be familiar with– installation sequence– proper weatherproofing– proper detail scale (usually 3” = 1’-0”)

Window Nomenclature Notations•Four typical areas for notations

•Head, Jamb, Sill, & Mullion

•Detail Assemblies are:

•Head--top of window - detail 11

•Jamb--sides of window - detail 13

•Sill--bottom of window - detail 14

•Mullion--vertical between windows - detail 12

Window Types - Styles Most Prevalent Windows Types:

– casement - vertical hinge and crank

– horizontal sliding - predominantly residential

– double(single)-hung - vertical sliding

– awning - hinges from the top of window

– hopper - hinges from the bottom of window

– louver (jalousie) - small glass panes allow venting

– 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
