Custom made by a local carpenter. The sliding rails are industrial to withstand the weight and made in Germany.

I will be building a house in Managua next year Francisco and wanted the folding door scenario but didn't know where to start! They are beautiful, could you give me an approximate cost for manufacture and installation. I would be so grateful. Thanks Zac

Zac, with pleasure. The cost of the doors are about $350 per square meter, including installation. The railing was sold by Molina Gomez and runs around $300 per linear meter.

Francisco,

For an outdoor kitchen area, I am thinking about building a 7 piece ) out of 2' x 5' craftsman windows to have a 14' wide 5' tall accordion folding center part of a wall, with the bottom starting about 3' or 2.5' above the floor. I have an excellent carpenter who built some other windows for me. Would we need the heavy german track system for something this size? What an inspiration! Thanks!
