French windows are an elegant window alternative which include two casement windows that open either inward or outward, similar to the operation of French doors.

== French Windows ==
French windows come as pairs of casement windows which open in the middle. They are placed in an exterior wall and are an appropriate replacement window option for both contemporary or traditional home designs. Both sides of a French window open fully, leaving a clear and unobstructed view. 

== Operation ==
The two sashes in a replacement French Window operate like that of a French Door. The Master sash can be opened and closed at will while the second sash, the Slave sash, has a floating mullion that opens when the Master sash is open. The French window has two bolts which lock the window in place.

Homeowners may choose inswing or outswing replacement French windows. Outswing French windows are popular in North America while European homes generally choose to install inswing French windows which are the traditional French window of Europe. 

=== Reasons for an Outswing French Window ===
The decision about which direction the windows will swing is dependent upon other architectural elements of the interior and exterior of the house as well as on the windows' frames. In some cases, inswing windows may interfere with window treatments or interior trim. In addition, if the windows are placed above a sink, desk or other indoor unit, a window which swings in may disturb the day-to-day functioning of the room, necessitating an outswing replacement French window. Window manufacturers generally offer custom-made outswing French windows and there is a higher cost associated with custom-made inswing windows. 

=== Reasons for an Inswing French Window ===
On the other hand, replacement outswing windows may not operate properly if the window opening is recessed or if the walls are deep. In some cases, an outswing French replacement window may interfere with a walkway or patio. Homeowners who plan to use screens for their replacement French windows may find that, for an inswing French window, placing the screen on the outside of the house detracts from the exterior appearance of the house.  

== Placement ==
French windows are an attractive window option for many areas of the house including attics, living rooms, dens, dining rooms, kitchens and bedrooms. Homeowners can install a single replacement French window or design a room with a number of French windows in a row for a particularly wide opening. French windows also offer an attractive look when they flank a French door.  

== Benefits ==
Many homeowners choose to install replacement French windows in their home because French windows offer a stylish look to the house both inside and out. When open, the French windows draw the outdoors into the house and, when closed, they provide the homeowner with an expansive view of the surrounding area. French windows are available in a wide variety of framing materials and colors and are suitable to different types of home construction including wood-frame, brick and stone.  

== Sizes and Shapes ==
Replacement French windows are designed for large spaces. French windows can be long and wide, with the option to place two, three or four replacement French windows side-by-side for a particularly wide space. Replacement French windows can be full-length windows, from a foot or more off of the floor to a foot or more from the ceiling. Other French window options include windows that measure 24 inches and higher. 

== Considerations ==

=== Framing Materials ===
The large width involved in a replacement French window necessitates a durable and weather-resistant window. Homeowners should research the options to make sure that the replacement French window is manufactured from a sturdy framing material. Framing materials for replacement French windows include aluminum, wood, vinyl and composite folding window frames. Each of these materials offers a different degree of resilience and insulation. 

=== Energy-Efficient Window Framing Materials ===

Framing materials with low U-Factors include aluminum, vinyl, fiberglass and wood frames with aluminum cladding. 

Good insulated replacement French windows are more costly, but the added expense of a properly insulated frame can be partially offset by government rebates and other programs which assist homeowners who are using energy-efficient materials for home renovations. In addition, the lower energy costs which result from energy efficient windows  compensate for the additional costs of purchasing properly-insulated replacement French windows.  

==== Wood ====
A wood-frame replacement French window can rot or warp if not painted annually. However French windows with aluminum cladding offer a weather-resistant, energy-efficient French window alternative. The aluminum cladding is specially treated to meet standards for good quality thermal insulation for all climates. Many of these windows are Energy Star windows, windows which meet the guidelines for energy efficiency as set by the U.S. Department of Energy and the United States Environmental Protection Agency.

==== Aluminum ==== 
Replacement French windows manufactured with a good grade of aluminum offer a variety of colors and a more economical French window. Aluminum conducts cold which, in cold climates, can result in a frame that produces moisture inside the house so homeowners who are interested in an aluminum window should make sure that the aluminum choice is an energy efficient grade of aluminum. 

==== Vinyl ==== 
Vinyl replacement French windows are another economical window alternative. Homeowners with vinyl windows report that they find easy maintenance and a sturdy window.

==== Energy Efficient Glazing Choices ====
Quality glazing presents a low heat/cold transference, slowing the rate at which heat and cold passes through the window's glass. French windows with superior glazing allow a home to preserve a comfortable temperature while minimalizing energy costs. Homeowners have several glazing insulating options for replacement French windows.  

==== Multi-Pane Glazing =====

==== Insulating Gas ====
Some window manufacturers pump insulating gas, specifically argon or krypton gas, into the gaps between the panes of a multi-pane window. The panes are safely sealed into the window's sashes to prevent gas leakage. The gas further insulates a multi-pane window.    

==== Low E Coating ====
A Low-E (low-emissivity) coating is an additional insulating element which, when added, makes replacement French windows an energy efficient window solution. The Low-E coating is a metallic-oxide coating which is coated on the window to further control the transfer of the sun's heat. The coating is invisible and reduces energy loss by 30% - 50%. 

== Accessories ==
The appearance of a replacement French window is enhanced by the hardware and accessories that accompany the window. Some of the accessories are standard with a replacement French window while others are optional. 

=== Screens ===
Screens for French windows are placed on the inside of an outswing French window and on the outside of an inswing French window. Some homeowners choose the window's opening swing based on where the screen will look best. Screens are removeable, allowing for easy cleaning. Standard-size screens are available for standard-size French windows and the manufacturer will custom make screens for custom-size French replacement windows.

=== Hardware ===
French windows require a variety of additional hardware to operate the window including handles, cranks and locks.
