A carpentry workshop of newly made wooden door and window frames, joinery tools and stacked timber — the joinery a schedule keys and a detail sheet describes.
Unit IVArchitectural Detailing and Working Drawing

Doors, Windows & Joinery

Keying openings to a schedule, and detailing the frame, shutter and fixing.

≈ 40 min + studio task

Every door and window on the plan is shown by a symbol and a mark — D1, W1 — keyed to a schedule that carries all the size and specification data, keeping the plan uncluttered. Learn how the door/window schedule is tabulated, how to detail the frame (chowkat) and shutter, how a frame is fixed with hold-fasts, the materials and typical sizes, and how to produce a joinery detail sheet with the jamb, head and sill sections a fabricator actually builds from.

3
CO4 · Understand

Choose materials and typical sizes and specify ironmongery and glazing.

4
CO4 · Apply

Produce a joinery detail sheet with jamb, head and sill sections.

Key, don't clutter

Schedules & sizes

Mark each opening and key it to a schedule that lists type, material, the structural-opening size, glazing and hardware — and align door and window heads at lintel level.[1]

Key the opening, schedule the spec D1 W1 marktypesize W×Hhardware D1flush1000×2100lock+3 hinge W1alum.1200×1200stay+lock Marks keep the plan clean; the schedule consolidates the spec — opening = leaf + frame + clearance.

Key, don't clutter

On the plan each door is a leaf + swing arc, each window parallel lines in the wall, each given a MARK (D1, D2 doors; W1, V1 windows/ventilators) keyed to a schedule. The plan shows location and swing; the schedule carries the size and spec. Dimension each opening's position (jamb to grid) and width. Writing full specs on the plan clutters it and breaks on revision.[1]

Rebate, hold-fast, sections

Frame, fixing & the joinery sheet

Detail the frame with the rebate equal to the shutter thickness, fix it with hold-fasts (3 per jamb), and produce a joinery sheet with jamb, head and sill sections — not elevations alone.[2, 3]

Jamb section — frame & hold-fast masonry frame (chowkat) — rebated shutter sits in rebate hold-fast (3 / jamb) in CC Rebate depth = shutter thickness, or the door won't close flush; a frame with no fixing is a classic omission.

Rebate = shutter thickness

Detail the frame (chowkat) in section — a member rebated to receive the shutter, overall size (timber 75×50 to 100×65 mm) with rebate depth EQUAL to the shutter thickness. The shutter is detailed by type: panelled (stiles, rails, panels), flush (ply-faced solid/hollow, 30–35 mm), glazed or louvred. If the rebate depth doesn't match the shutter, the door won't close flush.[2]

Joinery sheet — sections, not just elevation elevation (keyed) D1 jamb section (horiz.) head/sill (vert.) head sill Scale 1:5 / 1:2 so rebates, beads and gaskets read — an elevation alone can't be built from.

Vocabulary

Key terms

Chowkat / frame

The fixed surrounding member of a door/window, rebated to receive the shutter.

Shutter / leaf

The moving panel(s) of a door or window.

Hold-fast

An MS cramp fixing the frame into masonry, bedded in cement concrete (3 per jamb).

Rebate

A stepped recess in the frame receiving the shutter or glass.

Ventilator

A small high-level opening for air/light above doors or in wet rooms.

Ironmongery

Door/window hardware — hinges, locks, bolts, stays, handles, closers.

Apply it

Studio task

Prepare a door/window schedule for a two-room unit (mark every opening D1/W1, list type, material, structural-opening size, glazing, hardware, quantity). Then draw a joinery detail sheet for one timber door: a keyed elevation plus a horizontal jamb section (showing the frame rebate and a hold-fast in concrete) and a vertical head/sill section, at 1:5.

Check your understanding

Self-assessment

1. Door and window specifications are best placed —

2. A timber door frame is conventionally fixed to masonry using —

3. A joinery detail sheet for a window must include, besides the elevation —

In a nutshell

Recap

Show openings with marks (D1, W1) keyed to a schedule — keep specs off the plan.
The schedule tabulates type, material, structural-opening size, frame, glazing, ironmongery and quantity.
Detail the frame with rebate = shutter thickness; fix with hold-fasts (3 per jamb) or anchors, gap sealed.
Pick the right material vocabulary (timber rebates vs aluminium gaskets) and align heads at lintel level.
A joinery sheet needs jamb, head and sill SECTIONS at 1:5/1:2 — not elevations alone.
