Thermally Improved Aluminum

Depending on your region, you may be using Milgard Thermally Improved Aluminum windows. The use of thermal barriers in aluminum framed windows vastly improves insulating ability. Polyurethane is placed between the frame to create a thermal barrier and reduce the flow to heat. Milgard Thermally Improved Aluminum windows are equipped with this thermal break and as a result, are more energy efficient.

Not as a low-cost alternative

Milgard Aluminum windows was developed to address specific design requirements — not as a low-cost alternative to other material options. As a result, Milgard Aluminum windows have the flexibility to suit a multitude of projects ranging from custom homes to light commercial applications. Extremely popular with architects, aluminum windows help accentuate the clean lines of modern design.

Advantages of Aluminum Frames

  • Slim Profile
  • Durable
  • Narrow sight lines
  • Low Maintenance

Light yet strong, aluminum windows and doors can be configured into a wide variety of combinations. The narrowness of the frame places the focus on the glass and subsequently, the view it offers. Multi-panel door systems are often made with aluminum frames to facilitate indoor/outdoor living. Milgard aluminum frames are available in anodized or baked-on finishes for long lasting color. Sealed, mechanically joined corners stay square and true over years of use.

Milgard aluminum windows come in four beautiful frame colors to coordinate with your home design. Choose a clean, white finish or opt for a darker frame to emphasize the window shape.
