Bay Windows

A bay window is a combination of three windows of varying widths that dramatically extend from your home. This style is perfect for window seats.

Bow Windows

A bow window is very similar to a bay window, except it's composed of four or more equally sized windows, joined to form an even curve. This can add additional living space. For both bay and bow windows, any of the window panels can open, which provides a very customizable option.

    Rated 5 out of 5 by from Once You Go Milgard,You Don't Back! We love our windows. We remodeled a Mid Century Ranch using the black Ultra series,and now the house looks Spectacular. During the renovation we received so many compliments on the windows. Definitely a stand out in the neighborhood now!

    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
