The benefits of pultruded fiberglass frame technology is beautifully displayed in an Accurate Dorwin Sliding Patio Door, with large sheets of tempered glass appearing to float through the air while ultra low-profile frames keep the glass stable and protected.

Our patio door frames won’t warp, bow, dent or rot, and the low-profile provides the largest viewing area of any patio door around.



  • Ultra low-profile fiberglass frames provides strong, durable, and energy efficient protection for the large glass viewing area.
  • Adjustable tandem rollers allow the door to glide easily for quiet and smooth operation.
  • Stainless steel track doesn’t corrode, providing years of durable and trouble-free operation.
  • Warm Edge Spacer Technology reduces condensation on the perimeter of the glass for easy maintenance.
  • Anti-lift Sash Technology prevents unwanted sash removal for added security.
  • One-piece interlock provides a positive seal at the meet rail for greater energy efficiency and comfort.
  • Standard and custom sizing allows for design needs to be met in a dynamic and cost efficient manner.
