Exceptionally strong and low-maintenance fiberglass window and door frames from Milgard are ideal for any style and climate.
When you first look at Milgard® fiberglass windows, you might think you’re looking at an all-wood window. Designed to maintain their beauty in every season, and in any climate, Milgard fiberglass windows are like no other. Fiberglass is a frame material known for its strength, durability and performance. As a building material, fiberglass 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. Innovative window manufacturers like Milgard® have solved these challenges and today you can buy fiberglass windows and patio doors designed to maintain their beauty in every season, in any climate.
Fiberglass Windows have many benefits, including:
- Ultimate durability
- Energy efficient
- Extremely strong—can hold large expanses of glass
- Virtually maintenance-free
- Expand and contract very little with temperature changes
- Won’t decay
- Conducts minimal heat and cold
- Available in a variety of factory-painted colors
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.
