Overall Rough Opening Height = Sum of individual unit dimension heights.

For dramatic wall effects, the transom window is the perfect way to extend the vertical "reach" of Andersen® tilt-wash double-hung windows. They can cap individual double-hung units or help you build a "10-foot" high wall filled with style and character. Transom sash will accept spandrel panels for dramatic multi-floor effects.
Combinations shown on this page are designed with Andersen narrow wood mullions.
