Series 8400 Double Hung Tilt, Series 8700 Double Slider, Series 8500 Picture Window and Series 8500 Shapes

This exclusive PolyPour DYC Window System surprises many people familiar with residential markets. Double Hung windows are very common in expensive wood and replacement vinyl systems, but in aluminum? This unique, thermally broken double hung and its companion slider and picture window are most popular in high-end markets where buyers seek the features of two tilt-in sashes in a stout, durable window made with something other than wood or vinyl. The windows in this System are built in custom sizes to meet your unique needs and are available in White, Tan, or Bronze. In addition to our Limited Lifetime Warranty, its most popular features include:

  • Full Bettervue® screen is standard, allowing full ventilation with both sashes open.
  • Consider optional Full Solar Screen for added protection against solar heat gain.
  • Heavy-duty commercial rating for long-term durability and strength
  • Very tight double-hung design exceeds tough AAMA/WDMA/CSA 101/I.S.2/A440-08 standards.
  • Strong sash lock system for added security
  • 3¼” deep frame and sash feature heavy-gauge walls about 20% thicker than most “builder grade” residential windows
  • Glazed with full perimeter marine glazing boot that protects and further insulates the glass seated inside the sash frame
  • Patented tip-to-tip Eco-Ban weather stripping seals the sash in place for double protection against blowing wind, dirt, dust, pollen, and noise
  • Commercial adjustable balancers with exclusive top sash clamp ensure long-lasting operating function of both sashes
  • Environmentally friendly, VOC free durable powder coated finish for long lasting color retention.
Glazing Options
  • We strongly recommend our insulated glass package that combines Cardinal's 366 LoE Glass with patented Duralite™ butyl spacer system with Argon Gas for enhanced energy efficiency.
  • Patented Duralite™ butyl spacer is standard. Cardinal's XL Edge™ Dual Seal Stainless Steel Spacer Systerm with Argon Gas is optional.
