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 a total of seven, beautiful exterior frame colors available.

Ultra Series custom 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. Choose an energy package for your area and learn about ENERGY STAR®.

We will repair or replace any defect in materials or workmanship and will pay the costs of all parts and labor for as long as the original purchaser owns their home. Plus, if you sell your home, Milgard will extend the warranty coverage for 10 years from the install date.

Milgard Ultra Series window hardware is attractive, durable, secure, and easy to operate. Available in white, clay, dark bronze, brushed chrome or black. Choose from the Positive Action Lock or optional Cam Lock for single hung or horizontal slider windows. Folding nesting operator handles are standard for casements and awnings.

Ultra Series Operating Styles

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

Looking for a window that opens at the top? Ultra Series fiberglass awning windows open outward with a top hinge that allows airflow but keeps the weather outside where it belongs. 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 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.
