Types of windows

Last time we looked at the various parts of a window. Now we’ll look at some of the more common windows types and styles you might have on your house, or be thinking of getting.

Divided light

This is a style that can appear in many types of windows described below. It consists of a number of panes of glass divided by muntins.

Bay

A bay window is a projecting window, usually with three sections, one parallel to the wall, and the other two angled back to the wall. A bow window is a variation on this, but instead of sections, the window is curved. An oriel window is a bay supported by a bracket below, as you might see in medieval architecture.

Single hung

A single hung window usually consists of two sashes, one above the other. The top sash is fixed, while the bottom raises and lowers.

Double hung

A variation on the single hung, in this window, both sashes slide, which allows for easier cleaning, but makes weathertightness an issue.

Casement

A window in which a sash or a number of sashes swing outward on hinges.

Mullioned

A mullioned window may be a casement, a bay, or any series of windows divided by vertical architectural or structural members.

Fanlight

A window above a door or another window, which is usually in a semi-circular or semi-elliptical shape, with dividing bars radiating outward from the bottom center.

Palladian

Also known as a Venetian window, a mullioned window with a central arched section flanked by two narrow rectangular sections.

Transom

A horizontal window, usually fairly narrow, above a door, a window, or a set of doors or windows.
