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
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.
Thanks for the input Roy.
