Types of Window Frames

Awning windows are hinged at the top and open outward, allowing for ventilation even during a light rain. Often used in combination with other window styles or placed higher on walls for privacy, awning windows are easy to open and close.

Casement window, with latticed lights A casement is a window that is attached to its frame by one or more hinges at the side. They are used singly or in pairs within a common frame, in which case they are hinged on the outside.

However, these windows have many limitations, and in the long run a double-hung window is a better option for nearly all homeowners. Because only the lower sash opens in a single-hung window, the window offers limited ventilation.

In our lab tests, Double-hung window models like the Ultrex are rated on multiple criteria, such as those listed below. Wind resistance 0 degrees: Wind resistance measures each window's ability to keep out 25 and 50 mph winds at outdoor temperatures of 0ºF.

All About Window Frames. When you’re buying new or replacement windows, window frames are one of the most important factors to consider. They’re the structural backbone of a window, and a quality frame will keep a window functioning for decades rather than years.

Fixed windows are also non-operational windows, designed to let in light and add expansive views. The difference between Fixed and Picture windows lies in the frame size. Fixed windows have larger frames and are built to match the sitelines of accompanying operating windows, for a beefier, more contemporary look.

A window sill (also written as windowsill or window-sill) is the surface at the bottom of a window. They are not up top. A dictionary of architecture categorically defined the characteristics of a windowsill as: The lowest form of window casement. Windowsills hold pieces in place and slope downward to drain water.

In a single slider, one sash slides to open. In a double slider, both sashes open. Double sliders are great for providing air circulation, particularly if there is only one window in the room. Horizontal slider windows are available in these Milgard product series.

A stationary window has a thicker frame in order for it to blend in better with other, operable, windows that are adjacent to it. There are many features to consider when buying windows and many weird and wonderful words to describe them. Mulling, for example, refers to the joining of two or more windows together.

Transom windows start at under $100 for non-operable vinyl, wood, or aluminum frames, and go up in price for operable or intricately designed models. Some manufacturers offer cladding over a wood frame, which increases the cost of exterior transom windows but adds vital weatherproofing; these are often higher quality and can run in the hundreds of dollars.
