• Aluminum Windows - Dallas / Fort Worth
  In addition to having double or triple insulated glass, along with other performance options such as Thermal E+™ and tinting, a Thermalized window offers another important feature. The window frame and sash frames are insulated against heat and cold conduction. This is done by separating the outside metal parts from the inside with a material such as polyurethane, greatly reducing the amount of heat or cold transferred through the frames. This feature is known as a thermal break or thermal barrier.. Learn more about our aluminum windows.
