Our Vinyl Windows are Rated #1

Tuscany™ Radius Window

A vinyl frame is made from a compound – a recipe of sorts – that dictates its performance over time. Each additive to a company’s vinyl recipe helps determine the long-term characteristics of the final product; its weather and impact resistance, for example. How it handles the summer heat and winter chill. That’s why Milgard uses only the best quality vinyl material. Others may cut costs, but we don’t. Which is why at first glance competing windows may look the same, but don’t perform as well. You can trust Milgard vinyl windows and door frames to live up to every year of our lifetime guarantee. (Lifetime Warranty)


The Ultimate Building Material
Fiberglass itself is nothing new. It’s been floating boats and adding strength to ladders for years. But until recently, the complex profiles required for window designs have been impossible to attain with fiberglass. Milgard’s R&D team faced this challenge and engineered a window and door system that’s impervious to water, cold, heat, insects, salt air and ultraviolet rays. The end result: efficient windows and doors that maintain their beauty in every season, in any climate.

Milgard gives you two distinctive choices when it comes to fiberglass windows and doors: Ultra™ and WoodClad™. When you look at a Milgard Ultra series, you might think that it’s painted wood. Or in the case of our WoodClad series, you might even think it’s made out of solid Douglas Fir.

Experience the beauty of a wood window with the durability of a fiberglass frame. Make no mistake, our fiberglass windows will not crack, peel, bend/warp, or stick. A statement no wood window manufacturer can make.

The strength and durability of fiberglass is unmatched from any other frame material.

Not Your Grandfather’s Aluminum Window

For years, architects and builders have specified aluminum windows for their overall strength and lasting value. Because of their rigidity and durability, aluminum windows can be configured into large combinations with a large glazing area for maximizing views. These benefits keep aluminum popular as a frame material, but Milgard’s aluminum windows are much different than the aluminum windows of the past.

Milgard approaches aluminum windows as a design element – not as a low-cost alternative to vinyl or wood. As a result, our unique aluminum windows are found in homes and projects ranging from entry-level homes and multifamily projects to high-end custom homes and light commercial applications.
