After talking to a fire fighter

After a talk with a fire fighter...

I would like a fire wall between the garage and the house.
If there is a room over the garage, it will also be separated from the house by a fire wall.

Doors, ... did you know that doors are rated based on "burn time" ~ how long does it take for a fire to get through it.
He recommended getting a door between the garage and the house that has a 1.5 hour burn time.
He also said the weakest spot on a door is the door knob area. There should be a very tight seal on that.

So the door to the room above the garage, to the rest of the upstairs, should also have a door like that.
