Try Solar Innovations, Panda, maybe Weiland or Fleetwood.

Thanks! I should have asked - a decent quality Nanawall alternative! :)

Veka makes a nice European Vinyl fold and slide door with Roto Hardware. We have sent several to Islands and they have worked out well and they are considerably less than Nana. The vinyl door is more energy efficient than the aluminum.

If you click on the picture below it will enlarge.

I repeat!!!

Thanks everyone!

That gives me some good food for thought as I work out a project budget!

EURO-WALL SYSTEMS OFFERS THE BEST VALUE IN FOLDING DOORS. THEY ARE ARCHITECTURAL GRADE
DOORS WITH 10 Year Waranty KYNAR standard and SS hinges 888.989.3876 WOOD, ALUMINUM, CLAD

I can't comment on the quality of any of these, but here are a few options: Nana, Kolbe, Sunflex, Euro-Wall, Panoramic Doors, Lanai, LaCantina, Panda, Solar Innovations, Dynamic Windows, Veka.

I believe Panoramic will be the most affordable.

Has anyone tried FoldADoor? Im looking for a nana wall alternative as well and they came in about $2000 less than solar innovations

I really appreciate all of the back and forth feedback. My hubby and I are starting the design inspiration on a very small cabin in North GA Mountains. It will be our housing while we build our forever riverfront home. We purchased a plan and are begining to tweak it. There are two sets of bifold doors which I hear can be costly. So, these recommendations will come in handy. Thank you.
