Benefits of Milgard Aluminum A250 Series Windows
Aluminum Frame Strength
Milgard Thermally Improved Aluminum windows are made with strong aluminum frames that maintain structural integrity over time. They’re perfect for supporting large glass areas without bulky, obstructive framing.
Exterior Frame Colors
These windows are available in anodized finishes like Clear and Bronze, both chosen for their corrosion resistance. They deliver a crisp, clean look that fits modern and industrial designs alike.
Slim Frame Design
Aluminum frames allow for some of the narrowest sightlines available. That means more glass, more natural light, and uninterrupted views—all while maintaining excellent frame strength.
Durability & Energy Efficiency
Thermal breaks within the frame and Low-E glass help regulate indoor temperatures. Milgard Aluminum windows meet ENERGY STAR® requirements in select configurations to support efficient living.
Spring Action Lock Hardware
Easy-to-use spring locks and push-out hardware come standard and are matched to the frame color. They provide smooth operation and a streamlined appearance in every room.
Lifetime Limited Warranty
Milgard includes a Lifetime Limited Warranty on its A250 Aluminum Series. It covers defects and materials for long-term confidence in your investment.
