  • Heat Mirror™ coating – This highly innovative film prevents blocks 99.7 percent of UV rays from entering your home and is the same technology used to upgrade the 6,514 windows on New York City’s Empire State Building.
  • Exceptional noise reduction – Our windows will stop most infiltration of outdoor noise, resulting in a more peaceful indoor environment.
  • Double panes – With two panes of glass, our house windows are not only more energy efficient than most other windows, but they are also more resistant to high winds and break-ins.
