EnergyQuest™ Window System

The EnergyQuest™ Window System is specially engineered to maximize window energy efficiency and durability, featuring an isolated frame reinforcement and unique weatherstrip application to reduce air infiltration while improving overall thermal performance.

EnergyQuest is ideal for residential applications, meeting DP-50 residential structural ratings and offering heightened aesthetics, with a smaller frame cross section and larger glazing area that doesn’t sacrifice performance. For both new construction and replacement windows, EnergyQuest can also help OEMs meet and exceed ENERGY STAR® 6.0 criteria—all at a competitive price point.

Accommodating double- and triple-glazed insulating glass (IG) units up to 1-1/8" overall thickness, EnergyQuest suits a variety of needs in the residential space where efficiency and cost are key.

  • Block frame, or with integral nail fin at both 1'' and 1-3/8'' setbacks
  • Glazing unit capacity up to 1-1/8'' thick; exterior glazed
  • Integral frame accessory channels accept extensive interior/exterior frame accessory options
  • DP-50 residential structural rating capable
  • Foam-fill capable with thermal modeling optimized for maximum U-factor performance
  • Styles available:
    • Single Hung, Tilt Single Hung/Sloped Sill, Tilt Double Hung/Sloped Sill, Horizontal Slider, Double Horizontal Slider, Picture Window, Casement, Awning
  • Finishes available:
    • MikronBlend® Solid Vinyl Colors: White, Adobe, Almond
EnergyQuest® enables high performance and other benefits:
