Lexicon FAQ MCP About

Ironmongery.

What it means in interior design.

Ironmongery is the hardware on doors and windows: handles, hinges, locks, stops, closers and pulls. It is the part of an opening people touch every day.

In practice

Spend here: a heavy lever on a cheap door feels better than the reverse. Specify one family and finish across the home, and schedule it per door so the bathroom gets a privacy lock and the front door the right security rating.

Where the guide uses it

Door schedule

A door schedule is the table that lists every door on a project, each with a reference (D01, D02…) that matches the plan. It records size, swing, leaf and frame finish, ironmongery and any fire or acoustic rating.

Window schedule

A window schedule lists every window with its reference (W01, W02…), opening size, sill and head heights, glazing, opening type and frame finish. It sits beside the elevations rather than replacing them.

Structural opening

A structural opening is the raw hole in the wall, before frames, linings and plaster go in. It is always larger than the finished door or window it receives.

Threshold

A threshold is the transition at the foot of a doorway, where floor finishes, levels and seals meet. It decides whether a door is level, draught-proof and step-free.
