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. How does a Thermalized window perform? Thermalized windows are manufactured from close-tolerance aluminum extrusions. All of our thermal barrier aluminum frames are heat strengthened by bringing the raw aluminum up to a T5 temper to increase both strength and rigidity. This allows us to build extremely large windows without affecting performance like most aluminum windows. They have lower air leakage and higher resistance to heat transfer than non thermal break windows. With double glazing, they will stop 26% to 38% of the heat lost through comparable wood windows made at local millwork shops. A thermalized aluminum window performance is equal to or better than wellmade wood windows. Thermalized aluminum windows surpass strict industry specifications. Air leakage with a 25 MPH wind blowing outside cannot exceed 0.375 cubic feet
