Thermalized Aluminum Windows 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!
No window is condensation-proof. Even walls will “sweat” under high humidity. Windows do not cause condensation; they simply prevent moisture from escaping and provide a surface that allows condensation to be readily seen. If inside glass and frame surfaces on Thermalized window show excessive moisture, you can be sure that moisture is also present in your walls and ceiling.
The maximum recommended interior relative humidity ranges from 15% at -20ºF to a maximum of 40% at +30º. Many homes have been built “tighter” to conserve energy, leading to indoor humidity above the recommended levels. The best way to handle high indoor humidity is to vent the moisture to the outside. Bathrooms, kitchens and laundry areas should be vented with a fan, or by opening windows slightly when the areas are in use. If that does not help, a dehumidifier might be necessary.
