Durable and Energy Efficient

C650 Ultra Series fiberglass windows are heat and cold resistant, durable and low-maintenance. The frame expands and contracts at approximately the same rate as the insulated glass it holds, putting less stress on the seals for a clear view.

C650 Ultra™ Series Operating Styles

Casement Window

C650 Ultra Series casement windows allow for maximum ventilation in your home coupled with an unobstructed view. They hinge on the side and open just like a door. This fiberglass window style comes with a folding nesting handle set.

Horizontal Slider Window

With C650 Ultra Series horizontal sliding, choose from a left or right-side operable sash to allow airflow into any room. Ideal for windows facing a balcony or patio because they do not protrude toward the exterior of the home. Great for replacement window and new construction jobs.

Single Hung Window

C650 Ultra Series single-hung windows offer superior venting and daylight. The bottom sash is operable and opens by moving upward. Pulling downward closes and locks the window. Ultra Series fiberglass single hung windows have two choices for hardware: a Positive Action Lock™ or cam lock.

Picture Window

C650 Ultra Series picture windows are the best way to frame a beautiful view. These inoperable fiberglass windows let in natural light and can be used in combination with operable fiberglass windows if airflow is desired in a particular room.

Awning Window

C650 Ultra Series fiberglass awning windows open outward from the bottom allowing for excellent airflow. Awning windows come with a folding nesting operating handle.

Radius Window

C650 Ultra Series radius windows come in operable or inoperable styles. What sets them apart is the curved feature, which can be a simple arched top or even a circular window shape. A beautiful and elegant option, radius windows can also have grids added.
