Garage door requirements

Is a 1-3/8 metal door acceptable for the garage door between the home and garage? No fire rating label was found. The door appears to a regular metal door from Home Depot or Lowes. It was self closing and functional.

Yes, that sounds like a 20 minute rated door…no glass, correct?

Larry is correct as usual! 1-3/8"thickness is the minimum.

Are you sure it was metal and not a molded door?
1-3/8" thick door is indicative of an interior door.
In order to meet the requirement here; R302.5.1 Opening Protection.
Home Depot metal doors are usually panel doors also and are 1-3/4" thick.
To meet the Opening protection, it has to be a flush metal or wood door 1-3/8" through out with no panel configuration that would make the thickness less than 1-3/8" in thickness.
So the question remains, was it a flush metal door?

Marcel is correct. I assumed it was a flush metal door. At one time, Jen-weld made 1-3/8" flush steel doors in 32", though I have not seen any steel flush door in 36".
As a side note, doors between garage and the house are one of the items I call out 99% of the time. Either for the door, seal or lack of closer.

Same here…thanks, Marcel and Joseph.

Correct, No glass. Thanks for the input Larry :+1:t4::+1:t4:

Openings between the garage and the residence should be equipped with solid wood doors not less than 1-3/8” (35 mm) in thickness, solid- or honeycomb-core steel doors not less than 1-3/8” (35 mm) thick, or 20-minute fire-rated doors.
