Milgard® thermally improved aluminum windows have a light commercial rating. This means in addition to being excellent for use in homes, they can be used in schools, restaurants, government buildings and other light commercial applications. Their high-performance thermal-break frame design and higher thermal rating means greater energy efficiency. Milgard's sealed, mechanically joined corners stay square and true over years of use.
Our thermally improved aluminum windows feature Milgard's SunCoat® low-E high-performance insulating glass (standard in all Milgard windows and doors). They also include the Positive Action™ lock on sliding and single hung windows. When your window is closed, it's locked. No more wondering if you left a window unlocked in your home or business. For salt-air climates, Milgard offers an optional stainless steel hardware system to minimize corrosion. Like all our windows, our thermally improved aluminum windows are custom made to your home's exact specifications at no extra charge or extended lead time. What's more, they include our industry-leading Full Lifetime Warranty.
