Ultra™ Series Windows
The Ultra™ Series, as the name implies, is the ultimate window frame material for new construction and fiberglass replacement windows.
Because it’s made of glass fibers, it expands and contracts at the same rate as the insulated glass it holds. This puts less stress on the seals, reduces the chance for seal failure and results in a clear, fog-free window that lasts for years and years.
Milgard® Ultra™ Series fiberglass windows combine a traditional wood-frame profile with the strength, stability and low maintenance of fiberglass. Our fiberglass windows withstand the harsher sides of Mother Nature like no other window, yet look like traditional painted wood windows. In fact, you can choose any of our factory-painted exterior colors or paint the exterior yourself. And for multi-unit projects, Milgard offers the option of custom colors applied at the factory. Milgard fiberglass windows are custom made to your home’s exact specifications at no extra charge or extended lead time. You can customize them with our wide selection of hardware finishes and virtually endless grid options. All Milgard fiberglass windows are covered by our Full Lifetime Warranty with Glass Breakage.
