Durability and Energy Efficiency

Ultra Series Single Hung Fiberglass Windows

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.

Ultra Series Horizontal Slider Fiberglass Windows

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.

Ultra Series Fiberglass Casement Windows

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. 

Ultra Series Fiberglass Awning Windows

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.

Ultra Series Fiberglass Picture Window

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. 

Ultra Series Fiberglass Radius Window

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. 

Ultra Series Fiberglass Bay and Bow windows

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.

Ultra™ Series Windows is rated 3.7 out of 5 by 219.
Rated 5 out of 5 by from Excellent Had seven windows and two patio sliders installed 7/12/19 replacing the fourty-five year old originals. As expected the difference is great. They are beautiful and make a statement with the crimson exterior color. Only one issure with one screen that the seller is taking care of. Even the installers kept saying "man these are nice windows"! I'm sure they will last longer than I do! Thanks Milgard!!!

Rated 5 out of 5 by from Love the Black Bean Frame Installed for a new build. Interior and exterior in black bean, casement, picture, slider windows. It's a strong and durable framing and the casement mechanism looks durable. One thing to note since various trades that have come through after window installation:drywall, paint, finish carpentry etc, somehow a few nicks occurred in the window frame. In black bean, the white specks show up and it looked like paint specks but i learned sadly it was the black bean baked paint had been nicked through to show the white underlying structure. I did not notice until the windows and house was CLEANED from the construction dirt/debris. I love the look of the frame and did not install additional trim inside the window openings.

Rated 5 out of 5 by from Abosolutely amazing Just got this window installed and I could not be happier with the result. I have looked at many windows and my wife and I decided to this one out. The biggest difference between most windows and this one was the look of the frame. You can tell the quality if far superior to most windows. I will never recommend anything but milgard

Rated 5 out of 5 by from thrilled with the product! I am a senior citizen in a 1949 stucco home requiring 14 new windows. Tim Davis @ Agoura Sash & Door recommended Milgard to replace my existing windows. Excellent service, excellent turn around from time of order to final installation, thrilled with their perfect fit in my existing casings, could not be happier with the product. I highly recommend Milgard. It was a wonderful experience from start to finish! I feel that I got top quality with Milgrad at affordable prices. I am equally pleased with the Ultra Clad & the Wood Clad!
