Nanawall makes the door, and they have a variety of track options. The flush track is only for low-weather applications, so be careful!

@Klopf Architecture- thank you for providing that information.

@Fatalnyc- yes, we do have various sill options but it's incredibly important to choose a sill that works with the weather conditions in your area. To further discuss your specific project, I recommend you to use our Rep Finder and contact you local NanaWall Representative who will be able to walk you through our different systems and sills.

You can find your local rep's email and phone number by putting in your postal code into our Rep Finder: http://www.nanawall.com/reps-finder
