What section number do I use for a four-fold metal door. These doors are replacing the traditional overhead coiling sectional doors in fire stations. These doors open much faster than coiling doors.
Are you refering to doors like Door Engineering and Manufacturing’s F-Series Four-Fold Door?
If so, I would specify it in Section 08 35 13 “Folding Doors” or more specifically 08 35 13.33 “Panel Folding Doors.”
David: I just checked Door Engineering and Manufacturing’s website and they have a guide spec that you can use to start with, and they have it numbered 083XX under the MasterFormat 1995 edition.
The website for the spec is http://www.doorengineering.com/design_resources/four_fold/four_fold_specs.doc.
Yes! Door Engineering!
Seems like even manufacturers are confused about what section number they fall under!
