Chicago Replacement Casement & Awning Windows Installation

American Thermal Window carries a large selection of replacement casing windows and replacement awning windows. Casement and awning windows make a great alternative to single-hung and double-hung windows, especially when a sleek modern look is desired that still maximizes ventilation.

Casement Windows

With Casement Windows, the window is attached to the frame by one or more hinges and swings open with the use of a crank or lever placed at hand-height.

Awning Windows

Awning windows are similar to casement windows but have hinges at the top of the window instead of at the side. When opened, awning windows swing outward like an awning.

Casement windows and awning windows from American Thermal Window can be customized to match your home and personal tastes. Our casement windows can be installed with the crank either on the left or right side of the window. For a modern look, multiple awning windows can be installed in a stack in one opening or combined with fixed glass. The number of options for customizing your window project with American Thermal Window is endless. From choosing between wood or a number of other material choices to picking your hardware finish, American Thermal Window has the most-customizable windows in the Chicagoland area.
