What Is a French Casement Window?

Features

• When purchasing or installing French casement window frames, manufacturers advise homeowners and builders on different features that affect look and functionality. French casement windows are often promoted for providing the ability to control the amount of breeze coming into a home; energy-efficient materials such as insulating glass can prevent warm air from escaping through narrow cracks and openings. Different glass textures — hammered, beveled, gray tint and v-groove, to name a few — can also change the look of an otherwise simple French casement window. Locks are another feature that impact style and functionality. For example, crank and folding handles conceal locking mechanisms and allow windows to rotate inward. Other features to consider when deciding on the appearance and operation of French casement windows include glazing, jambs, screens, rails and handles.

Types

• Property owners also have a range of wood types to choose from when considering the finish for French casement windows. Interior and exterior finishes accentuate the look of the casing or wooden paneling surrounding the window. They also give the windows a distinctive look, as finishes can be completed using different materials and colors. For example, some manufacturers offer finishes in pine, white oak and douglas fir oak. For darker finishes, cherry oak, mahogany and cedro macho highlight French casement windows with deep brown and reddish tones. Other types of finishes come in the form of beading. Some beading styles include chamfered, ovolo and sash horns.

Benefits

• In addition to their ability to mimic the movement and style of French doors, French casement windows allow ample light into rooms. The windows’ functionality also enables access to both sides of the glass from indoors for cleaning purposes. French casement windows are common in small or tight spaces where there is need for a fire escape exit. Moreover, sash locks provide added security from intruders and help insulate rooms from cold external temperatures.

Considerations

• Despite the advantages of installing French casement windows, there are some drawbacks. Builders and owners should consider orientation when installing French casement windows, as the windows may knock into each other upon opening or closing. Additionally, French casement windows may not be practical for larger spaces. However, homeowners can consider using custom designs and hardware to incorporate features and functionality similar to French casement styles.
