Replacement Casement Windows by ComfortSmart

When you want to come home to contemporary styling and state-of-the-art performance.


Casement and awning windows are stylish and have functional beauty with energy efficiency.

Their narrow sight lines present a large viewing area. As well, color-matched locking and operating hardware seamlessly combine easy operation and high security.


Just the simple lift of a single locking handle simultaneously activates a system of multiple locks along the entire window jamb. Our interior glazing bead also deters glass removal from the outside and provides a waterproof seal to protect the insulating glass.


These windows are as rugged as they are attractive. The multi-point locks are combined with heavy-duty weather-stripping and insulation in both the mainframe and sash providing superior thermal performance and one of the lowest air infiltration rates in the industry.


Yet the real beauty of these  windows is their heavy-duty construction never requires painting, caulking or maintenance. The casement hardware allows full opening for safe, easy cleaning, and the screens are removable from inside the home to make cleaning even easier!


  • All frames and sashes are fully fusion-welded and guaranteed to never separate.
  • Heavy-duty locking and operating hardware is guaranteed for life.
  • Insulated glass is even warranted against breakage.
