Aluminum Replacement Windows in the DFW Metroplex

About Us:

We make your replacement windows right here in our Dallas, Texas factory. When you come into our plant/showroom you will see the quality and attention to detail that has made us “America’s Finest Window” since 1992. We offer vinyl replacement windows, thermally broken aluminum replacement windows, and fiberglass replacement windows at factory direct prices. We offer all of our windows ready for new construction as well as for retrofit.

The window frame and sashes are insulated; this is done by separating the outside aluminum extrusion from the inside extrusion with a material such as polyurethane, reducing the amount of heat or cold transferred through the frames. This feature is known as a thermal break or thermal barrier.

Thermalized aluminum windows surpass strict industry specifications.

Air leakage with a 25 MPH wind blowing outside cannot exceed 0.375 cubic feet per minute (CFM) for every foot of weather-stripped window perimeter. Our 700 Series Double Hung allows only 0.06 CFM air infiltration – one sixth of the industry standard! Old, worn out windows often have rates of 1.5 or more, 25 times the air leakage of our best Thermalized aluminum windows!
