VINYL
Our Vinyl Windows are Rated #1

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.

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.

Advancing Fiberglass

Milgard's fiberglass windows are produced using a process known as pultrusion. Glass rovings and mats (shown at left) are pulled at tremendous forces through a resin bath and a series of dies. These materials combine and catalyze to provide unparalleled tensile and torsional strength.
