Milgard Ultra Fiberglass Series: The Future of Window Innovation

When it comes to home improvement, one often overlooked but crucial element is the window system. Not only do windows contribute to the overall aesthetics of your home, but they also play a critical role in energy efficiency, comfort, and durability. Enter the Milgard Ultra Fiberglass Series, a groundbreaking solution designed to offer long-lasting performance with minimal maintenance.


Why Fiberglass? The Superior Choice

Fiberglass has increasingly become the material of choice for high-performance windows, and for good reason. Unlike vinyl or wood, fiberglass offers unmatched structural integrity and longevity. It’s resistant to swelling, rotting, warping, and even extreme temperature fluctuations. This makes it a reliable option in diverse climates—from coastal humidity to desert heat.

The Milgard Ultra Fiberglass Series uses pultruded fiberglass, a highly durable material that combines glass fibers and resin. The result is a robust frame that doesn’t compromise on aesthetics or thermal performance.


Built for Strength and Stability

One of the key highlights of this series is its structural strength. Fiberglass is known to be eight times stronger than vinyl, providing a solid, secure frame that stands the test of time. This makes the Ultra Series ideal for large window openings and multi-pane configurations.

Benefits of Structural Integrity:

  • Supports larger glass areas
  • Minimizes flexing and bowing
  • Improved air and water resistance
  • Ideal for high-wind or storm-prone areas

Designed for Beauty and Flexibility

Aesthetically, the Ultra Series is nothing short of impressive. The frames are designed to replicate the look of painted wood while offering the performance of fiberglass. With rich, baked-on color options for the exterior and a clean white or paintable interior finish, these windows can easily complement any architectural style.

Available Colors:

  • Black Bean
  • Espresso
  • Bronze
  • Frost
  • Harmony Gray

These durable finishes are engineered to resist fading, chipping, and chalking, ensuring your windows look great year after year.


Energy Efficiency at Its Core

The Milgard Ultra Fiberglass Series isn’t just about looks and strength; it’s also a leader in energy efficiency. The windows are equipped with dual-pane or optional triple-pane glass, filled with Argon gas and coated with Low-E technology.

Key Energy-Saving Features:

  • Low-E Glass reduces harmful UV rays
  • Argon gas fills for better insulation
  • Thermally broken frames prevent heat transfer
  • Optional SunCoat and SunCoatMAX coatings

These features help reduce heating and cooling costs, making your home more comfortable and environmentally responsible.


Variety of Styles to Fit Every Home

No matter your home’s design, there’s a window configuration in the Ultra Series that fits your needs. Choose from:

  • Casement Windows: Side-hinged and easy to open
  • Awning Windows: Top-hinged and weather-resistant
  • Single-Hung Windows: Classic design with a moving bottom sash
  • Horizontal Sliding Windows: Modern and space-saving
  • Picture Windows: Large fixed panes for maximum light
  • Radius Windows: Curved for a unique architectural touch

This versatility makes the Ultra Series perfect for everything from modern builds to historic restorations.


Low Maintenance, Long Life

Unlike wood, which requires regular sealing and painting, fiberglass needs minimal upkeep. A simple wipe-down with soap and water keeps your Milgard windows looking pristine. Plus, the non-porous surface prevents mold and mildew buildup.

Maintenance Advantages:

  • No repainting required
  • Weather and UV resistant
  • Insect and moisture-proof
  • Easy to clean and maintain

Sound Control and Peace of Mind

Beyond thermal insulation, the Ultra Series also offers excellent acoustic insulation. For homes near busy streets or noisy environments, these windows significantly reduce sound penetration, enhancing your indoor tranquility.


Environmental Responsibility

Milgard is committed to sustainable practices, and the Ultra Series reflects that. Fiberglass production has a smaller environmental footprint compared to vinyl and aluminum. Moreover, its durability means fewer replacements and less landfill waste.

Sustainability Highlights:

  • Made from recyclable materials
  • Long lifespan reduces resource consumption
