There is more to a window than what meets the eye.

Whether building, renovating, or just trying to expand your window and door vocabulary, learning the different parts of a window is a useful step. Here is the anatomy of a window:

1. Head – the main horizontal member forming the top of the window frame.

2. Argon Gas – a colourless inert gas that is injected in the airspace of an insulating glass unit to improve energy efficiency

3. Frame – the enclosure in which window sash or door panels are mounted.

4. Simulated Divided Lites (SDL) – small grille bars placed on the exterior and interior of the glass that divide a window into smaller section.

5. Nailing Flange – fin used to secure the window to an opening

6. Sash – a single assembly of stiles and rails into a frame for holding glass

7. Pane – a framed sheet of glass within a window or door

8. Glazing – the act or process of fitting a window with glass

9. Sill – The main horizontal member forming the bottom of the frame of the window.
