I just subscribed to her free site. There are some interesting discussions that cross over into building code issues. Better and more thorough code discussion on this board.
 
I ended up on her site through a google search. Question was asked of me regarding what the max undercut can be on a "fire" door. There was a great blog from her on there, answered the question perfectly.
 
I needed fire door inspection forms. She sent some and a handy guide about doors. My customer was impressed with my vast knowledge of fire doors. I smiled and said Thank You.

She knows of that which she speaks.
 
Awww....THANK YOU!!! This site is #2 in referrals to my blog, with Google being #1. I appreciate all of your help, and yes Coug Dad, this site has better and more thorough code discussion but if you ever need anything pertaining to doors or hardware, you know where to find me. ;-)
 
Lori:

I have a question now, what is the highest quality automatic door bottom for exterior doors? I've used Pemko for many years but have never been that satisfied with them, they will be morticed into 2¼" doors, but if necessary I could have the doors built thicker. I've even looked at English products but haven't called yet, I am building in our Wildlands-Urban Interface zone, so want the best for both fire-protection and air-sealing. I cannot use a raised threshold.

good question, I don't know. All I know is Ingersol Rand will talk to you if you have problems with thier products, no matter the age. They have rebuilt closers for me in the past.
 
Well, Pemko is not part of the IR group, it is part of the Assa/Abloy group.

As long as I'm here, I'll respond to conarb: Auto door bottoms are generally contra-indicated at high use doors, creating a maintenance headache. You indicate no threshold... what is the floor condition? If there is no elevated smooth surface for the door bottom to rub against, the life of the seal will be very short. If a mortised door bottom, its replacement requires the door be removed.

As far a manufacturer, if a similar product from any manufacturer is specified you should get similar results. Pemko, Reese, and National Guard are a few common manufacturers.

Rebuilt door closers are another misunderstood area. Yes they can be rebuilt, but this is usually done only when a simple replacement is impractical. Watch out for fire rated doors... was the closer rebuild actually done at an approved facility?
 
Doorman:

Interior floors are honed lava stone flowing out to a terrace with flamed lava stone, I will transition with a polished stone threshold with a ¼" rise, hinges will be Rixson.
 
"... I will transition with a polished stone threshold with a ¼" rise..."

The most common use of auto door bottoms is with the sponge neoprene insert. As long as the sweeping motion of the ADB is over a smooth surface, that will help longevity. An irregular or carpeted surface will tear the rubber up, or simply tear it out of the frame.

I am presuming you are using a Pemko 434_RL. The model 434_NBL is less fussy about the floor condition, but is not as good a sound limiter.

Rixson hinges, or offset pivots? How will pivots work with an ADB?

I don't know, I may have to give up on the Rixsons, this is California and the primary concern is indoor-outdoor living that flows without tripping over a threshold, clean design without protruding hardware is secondary. I guess I better call the Rixson representative, thanks for pointing out the potential conflict.
 
conarb, my question regarding the use of pivots and mortised auto door bottom together is rhetorical. That pesky rule about two things occupying the same space at the same time will come into play.

If the door is heavy then pivots is most likely the proper selection. With pivots the majority of the axial load is borne by the floor system instead of the frame.

I'm sort of taking up Lori's oxygen here. Perhaps another thread can be started and this sort of thing can be discussed there. So, if you will excuse me, I am going to go Dig some Hardware. 8-)

As Doorman said, I wouldn't specify an auto door bottom for an exterior door because they don't hold up well over time. I would just use a sweep but the sweep should have a raised threshold to seal against.

Doorman - Thanks for covering for me while I was traveling to Florida. Don't ever worry about taking up my oxygen.
 
Lori & Doorman:

Code only allows ½", ADA only allows ¼", everybody building a modern home in California wants an uninterrupted flow from inside to outside and vise-versa, in addition the door has to be far enough off the floor to clear at least ½" for oriental area rugs in the entry, this wasn't a problem until air-sealing entered the codes, there has to be a way. I'll call Rixson but I'll probably have to make do with high quality butt hinges and a Pemko auto door bottom.
 
conarb, you said "Code only allows ½", ADA only allows ¼"..."

All the documentation I have indicates a 1/2" overall height threshold complies with ADA. No?
 
Are you posting about a Single family? Multi Family? Office? Mercantile?

I agree with Lori Automatic Door bottoms on exterior doors. They dont last.

Surface mounted ones also do not meet ADA
