We’ve all been there – You know what you want, you can picture it in your mind, but you don’t know how to communicate it exactly.

Whether you’re renovating or building from scratch, learning about all the different parts of a window can be overwhelming, and dealers or contractors might often forget that you don’t necessarily understand the correct terminology or vocabulary.

Familiarizing yourself with all of the moving pieces will not only help you build confidence when it comes to asking questions, but it’ll allow you to easily express your wants.

1) Head

The head is the main horizontal piece that forms the top of the window frame.

2) Argon Gas

Argon Gas is a colourless inert gas that’s injected into the airspace of the insulating glass unit to help improve overall energy efficiency.

3) Frame

The Frame is the main portion that supports the entire system and holds the sashes in place.

4) Simulated Divided Lites

Simulated Divided Lites, also known as SDLs, are small grille bars placed on the exterior and interior of the glass that divide the window into smaller sections.

5) Sash

The sash is the part inside the frame that holds the glass. On a single-hung window, the piece you slide to open the window is the sash.

6) Pane

Self-explanatory, but still important, the pane is a framed sheet of glass within the window.

7) Glazing

Glazing refers to the act or process of fitting a window with glass.

8) Sill

The sill is the main horizontal piece that forms the bottom of the frame of the window.
