Topic 1 – Door Terminology and NBC requirements
Door Terminology
In order to install and repair doors a carpenter must be familiar with the terminology used. Doors and their frames have many moving parts which can cause operating problems if not installed correctly. Door frames may come with single or double rabbeted jambs.
Parts of a door jamb
- Side jamb – vertical members of the frame
- Head jamb – horizontal top member of the frame
- Sill- allows door to clear the floor
- Threshold – metal or wood strip that runs under the door often part of the sill
- Mullion – vertical member between a set of double doors provides a means of latching
- Astragal – acts as a door stop in a set of double doors
- Transom Bar – horizontal member that separates a window from the door
