Thermally Improved Aluminum

Milgard Thermally Improved* Aluminum windows, (also known a Thermal Break), consist of extruded aluminum, where a “channel” is cut through the aluminum and polyurethane is poured into this channel to separate the interior from exterior extrusion. This process is done to reduce thermal transfer and improve energy efficiency.

The benefits of Thermally Improved Aluminum include ALL of the same as Standard Aluminum, plus more energy efficient options with less heat/cold transfer through the aluminum frame.

  • Narrow sight lines to inspire design freedom
  • Improved energy efficiency
  • Full Lifetime Warranty
