Awning Windows

Awning windows are so named because they hinge at the top of the sash and look like an awning when open. They operated just like casement windows, usually opened with a crank. They are especially popular in locations where you need to reach to open the window, such as over a sink. Awning windows can also be used over a door, as part of a combination window or double-stacked to give the appearance of a double-hung window from the outside. Efficient ventilation when open and good energy efficiency when closed are two hallmarks of awning windows.

Materials and colors

There are two main components to these windows: the frame and the glass. The most popular frame materials are vinyl, aluminum, wood, and composite. Vinyl and aluminum are weather-resistant and virtually maintenance-free, while wood and composite require periodic painting. Aluminum and vinyl frames can be ordered in a variety of standard and optional colors, which can be selected to match the overall color scheme of your home. Available colors range from white and black through earth tones and hues of blue, red, burgundy, bronze, and more. Aluminum frames are typically anodized and the colors of vinyl frames are impregnated in the material. Wood and composite frames can be painted or stained to match your home's color scheme. The other component, the glass, can be ordered in single, double, or triple panes with a variety of coatings and a selection of gases between the panes.

Energy efficiency

Awning windows provide excellent energy efficiency in part due to the compression seals used to provide a positive seal when closed. However, an awning window's overall energy efficiency depends primarily on the materials used. When determining energy efficiency, there are several terms you should be familiar with:

1. R-Value - a measure of the heat loss through a window. The higher the R-Value, the lower the heat loss
2. U-Value - measures window performance in preventing air leakage between the sash and the frame. The lower the number, the better; 0.35 or lower signifies an energy-efficient window
3. Energy Star - a government certification program. Energy Star windows may qualify you for tax rebates
4. NFRC ratings - NFRC stands for National Fenestration Rating Counsel. An NFRC label on a window certifies that it will perform as advertised

Options such as argon gas between the panes and a low-e coating can significantly improve a window's energy efficiency. Low-e coatings should be applied to the outside window surface in hot climates and the inside surface in cold climates.

Manufacturers and costs

A number of window manufacturers produce awning windows in a variety of materials. Some of their more well-known manufacturers are Andersen, Gorell, Hurd, Jeld-Wen, Loewen, Mildgard Windows, Pella, Thermal Industries, Inc. and Weather Shield. You should expect to pay anywhere from $400 and up, depending on size, materials, and manufacturer.
