Our High-Quality Sliding Patio Doors

Our patio doors are sourced from OKNA, the same company we trust for vinyl windows. And, just like those windows, these patio doors are highly energy efficient. You’ll also love features like:

  • A thermally welded multi-chambered 5-5/8″ vinyl frame that provides superior strength and thermal insulation.
  • An interlocking meeting rail system with double weather-stripping for reducing the infiltration of air, water, dust, and noise.
  • An anodized aluminum screen track, roller track, and threshold for increased strength, durability, and longevity along with an elegant appearance.
  • An operating sash equipped with adjustable, precision bearing tandem rollers for a smooth and quiet operation.
  • Our HeatSeal spacer, which gives your home excellent thermal efficiency and drastically reduces condensation.

All of our windows and doors are manufactured using high-quality materials and are backed by a Transferable Lifetime Limited Warranty.
