I'm selling my house and one of the things the buyer wants corrected is
the interior door from the house to the garage. It is a solid core
wood door that I cut a hole in many years ago for a pet door. He has
asked for a "fire-rated" door to which I agreed.
The guy at Lowe's told me fire-rated doors are exterior grade steel
doors and of course the one I need is not in stock and must be special
ordered. Is it true this door will have to be steel and if so will the
old door frame work if I just replace the door itself at the hinges?
Contact the Building Inspection Dept. in your city to get the straight
scoop on what will pass a 'fire rated' code. Maybe it will turn out
that a steel door and a wood frame are OK for residential. The chap at
Lowe's was probably thinking along the lines of an industrial door.
There are probably many steel doors available in stock at the box
stores if your code is typical. Good luck.
In the U.S., the International Residential Code requires either a 1
3/4 inch thick solid wood door or a 20 minute rated door. These are
available in wood. A real builders' supply house or hardware
distributor should have the information.
I have the same door to garage set up as you. I wanted to replace that
door a few years ago.
At that time, the store (Home Depot) did have wood fire rated doors.
However, to be "fire rated" (which is what you agreed to), it actually
has to be "stamped" and certified as such. Furthermore, I believe they
only would sell them as pre-hung. I forget the logic now, but it may
have to do with what another poster said. The new code is the door to
the garage also has to have spring loaded hinges and one of those
super duper weather sealer that ends up poking up from the bottom and
goes up into the door when shut.
The other problem you may have, if an older house like mine, is they
often used slimmer doors, which is no longer acceptable. So the good
news is you can get wood if you want. The bad news is most likely you
will have to have a new frame and meet all the new codes.
Yes, I seem to be having an issue finding a 30" solid core door to
replace mine. Several places I've called don't seem to carry such a
thing. We do have a RE Store locally that I will check for
