Cascade “Warm Edge” Awning Window

Architects, homeowners and building professionals can all appreciate the Cascade Series. This innovative designed line blends classic looks with solid structural integrity and additional features. Enhance your custom home or commercial project with the classic, traditional styling of our signature Cascade Series. This line is built structurally sound and requires surprisingly little maintenance.


The Cascade Series offers a distinctive appearance normally associated with wood windows. They feature a fixed sash, giving the window true visual balance.


The fixed sash unit is set back from the outside of the frame, offering the depth and sight lines of traditional wood windows. The frames of the Cascade Series’ picture, casement and awning windows provide the same consistent look.


Cascade Series sliders and single-hung windows feature AutoLocking hardware. Cascade casement windows feature multipoint locks and smooth operating handles. The Cascade door features an upgraded heavy-duty screen and a secondary lock. Security is built into the Cascade Series.
