Windows and their Parts

Understanding the different styles of windows and window parts can help a homeowner when windows need new framing, an apron, a window sill replacement, and more. By understanding the types of windows, their advantages, and their operation, it’s easier for a homeowner to make decisions about wood treatments for his windows. Here are some of the types of windows we see in home restorations and replacement of wood components:

Picture windows

Picture windows don’t have any operable parts, and therefore don’t open. But, they provide gorgeous views because they can be expansive in size, allowing more light into the home. 

Slider windows

Slider windows open horizontally by sliding along a track. It can be a single track or more than one along the same expanse. Sliders are a good option for wide expanses of window area.

Casement windows

Casement windows swing outward from a hinge on one side. They’re powered by a crank, which has a handle that can be neatly tucked away. These windows can provide excellent ventilation for the home. They are also easy to clean without the need to go outside or use a ladder.

Double sash windows

A double sash window is one in which the top and bottom units slide up and down vertically to open. They’re very popular and thus the more common option. Newer windows can also tilt inward for cleaning.

Single sash windows

In the case of a single sash, only the bottom unit slides up and down. The top part doesn’t move. This is the more traditional style, one which produces a more ‘authentic’ look.

Some other terms

These terms can also be useful to the homeowner in pursuit of a new look for their windows:

• Window frame

A window frame is comprised of the header on top, the sill on the bottom, and the jambs, or vertical side pieces. The frame is what attaches a window to the wall. 

• Sash

Inside the window frame is the sash, which can move or not.

• Apron

The apron is the horizontal piece below the sill and can have a variety of decorative styles.

• Muntin

The bars between the pieces of a glass window that make a big window smaller panes are called the muntin.

When wood decays or is damaged by weather or other conditions, we can remove and replace or restore these damaged components. A newly renovated window sill or window apron can replicate the former look, or a new style can be created. 

Before making a decision, a homeowner should go through the potential options with a wood expert who is familiar with these types of jobs. Windows can be a stand-alone project or be restored in conjunction with door restorations as part of a similar theme or style throughout the home.
