1. Stiles

The anatomy of windows starts with stiles. Stiles are the vertical supports placed within the frame on both sides of the window.

2. Mutins

Mutins are the grids on the window. They sometimes have a functional purpose, which would be to hold the glass in place, or for aesthetics where mutins are snapped into place for a nice look.

3. Jambs

Jambs are the vertical supports that form as the rims of the window. They are the actual sides of the window, unlike stiles.

4. Rails

Rails are the horizontal components within the frame which fit within the stiles. Every window, no matter the style, has a top and bottom rail.

5. Apron

The apron, or skirt, lies in the window frame’s interior. It is a trim board placed flat against the wall under the stool.

6. Casing

A side casing can be found on the window’s exterior, interior, or both. It is a trim that serves a decorative purpose. It is also known as a molding or exposed framing that covers the small space between the wall and the window’s side. A head casing is similar, except that it covers the space between the wall and the top of a window.

7. Glazing

The glazing is simply glass contained within the window’s frame. Glazing can come in three different types of thickness: single, double, or triple.

8. Sash

A Sash is the actual window frame that keeps the glass in place. It is composed of two stiles along the side with rails at the top and bottom.

9. Stool

The stool, also known as the sill, is the bottom horizontal portion of the window. It is like the interior shelf part of the window.
