Fire Rated Doors.

Are solid core wood entry doors fire rated? Are the metal clad hollow core doors fire rated?

Everything is fire rated. You might not like a rating of zero with a flame or smoke contribution number off the charts, but it is rated.
What rating are you required to meet? Where is the door located? I think what you are asking is what rating your doors have. Most solid core (particle board / SCL) flush doors are considered to have a 20 minute rating if in the proper jamb, of course most manufacturers make doors on up to 3 hour. Taylor offers a high end residential metal door that can make 90 minutes. ______________________________ Keep the whole world singing . . . . DanG (remove the sevens) snipped-for-privacy@7cox.net

You have to talk to your town. A friend has a rental property that the doors *became* fire rated after the town told him to paint them with fireproof paint.
The *fire* door between my house and the attached garage is a standard luan interior door with a thin piece of metal nailed to the garage side. If I had a fire in the garage that door would last maybe 5 minutes but the town said it was ok because somebody nailed a piece of galvanized steel to it.

You are mistaken about that door to your garage. It will last a little longer then five minutes though exactly how long a given door will last under fire conditions in the real world no one can reliably say. The technique you describe is called a tin clad door. They have a fire resistance rating of twenty minutes when tested in the laboratory. That is the same resistance as a single layer of half inch sheet rock. The use of a tin clad door in such a wall opening is a violation of the building code in most jurisdictions. All five of the nationally recognized building codes require a listed door and frame assembly in any opening in a fire wall. A genuine Kalamein door, which is a fire door whose solid wood core is covered with galvanized sheet metal, would carry a laboratory listing mark to indicate it's fire resistance in minutes. The laboratory label would be installed on the edge of the door that is in contact with the hinge side of the frame when the door is closed. A door installed in a two hour wall requires a resistance of 1&1/2 hours.

Depends on what hour rating is required. Where a "fire door" is normally needed, in residential construction, is between an attached garage and the house. This requires not just a rated door slab but a rated door system. This includes a metal jamb, door and sill. Your local building dept will tell you what is required for your application.

look at the UL label on the door for the rating. what assembly is required for one dwelling differs for another under your local building codes. which rating is required for your application? link: http://www.ul.com/fire/doors.html main page: http://www.ul.com /
