Exterior Frame Colors
Looking for a dark interior frame to match the exterior? You’ll find it with Ultra Series fiberglass windows. Choose Bark or Black Bean to create the popular dark window frame look. We have four beautiful exterior frame colors available.
Durability and Energy Efficiency
Ultra Series fiberglass custom 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. Choose an energy package for your area and learn about ENERGY STAR®.

I am glad I went with Milgard, for the quality and the value. I'm very happy about the lifetime warranty too. No one else offers that in a fiberglass window.

Single Hung
Chose a single hung window for 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.
Horizontal Slider
Horizontal sliders are a common window style. 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.
Casement
Choose a casement window 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.
Awning
Ultra Series fiberglass awning windows open outward from the bottom allowing for excellent airflow. Awning windows come with a folding nesting operating handle.
Picture
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.
Radius
Ultra Series fiberglass 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.
Bay and Bow
Bay fiberglass windows are three-segment units that expand your space to the outdoors. Bow fiberglass windows are four or more equal-width panels that create a dramatic, curved space in your home. Add operating styles for airflow in addition to daylight.
