In my shop (up in the shops forum) I'll have an interior wall separating the shop from the storage room. I want a door between them (duh!) but I would like to have a 6' wide double french door (both swing); preferably with no threshold so i can easily roll tools boxes and tools between the 2 rooms. Even so, it will have to seal somewhat, since the storage portion will not be heated, and the shop will. Right now I'm thinking I could buy an exterior french door (patio door, I can get them for about $400 at Menards) and modify the frame to eliminate the threshold and sit the doors within maybe 1/2" of the floor. I could then use draft stoppers to seal the bottom when needed. I'd really like to avoid having the threshold there. Any other ideas?

On my exterior double doors, I got that one with an ADA compliant threshold so the "bump" is pretty minimal. This keeps everything sealed nicely and I have rolled machines in and out without any problems.

 

If you are dead set on not having a threshold, I would think what you want to do could work without any problems.

Never thoutgh of looking for an ADA door, that might work. I'll have to find one and see. Thanks!

note...

pile brush all the way around will serve you better than foams, rubber or neoprenes that will wear out in no time...

How about a sliding door, interior or exterior, if you have room an exterior would work. An interior would need a little framing adjustment.

These hinges save the day for your application Fred.

Have you made any headway on the door part of our project yet @Fred W. Hargis, Jr?

No, too many other things going on. At this point I'm just thinking things through.I like the sliding door idea, but not sure how I would make it seal. I wasn't worried too much about the swing, but having them go both ways could be handy.

smoke or weather seals...

install them like stop molding..

I got a set of pre-hung double doors, including hardware, at Habitat Re-Store for $35 recently.   Might be worth checking in there from time to time.   No threshold, but if I was worried about sealing, I'd put in some floor sweeps, assuming the floor is relatively flat and level.

I've seen moveable door sweeps that accommodate for unevevness in the floor. But Fred's slab looked pretty darn flat.

Now there's an idea, I'll have to keep my eyes peeled.

If the doors are not something you are using every day, there is a product (whose name escapes me at the moment) that is a waterproof fabric and has a padded roll on both sides and a flat connector across the bottom.  So when the door(s) are closed there is an insulation roll on the base at both sides of the door.   As you open the door, it slides along the floor.  Not something I'd want on a door I used 10 times a day but for occasional use, I think it would be fine.   I've seen these on people's front doors.

I was planing on making a double swing door after a door model I saw in heritage home design windows and doors http://www.heritagehomedesign.ca/ . You could make a door swing in both ways by following a couple of steps.I read these from an article online:

 

1. Firstly remove the door from the opening and then remove the hinges,doorknob and the striker plate.

2. Insert the tip of the prybar behind doorstop to pry it off.Cut ½ inch off the width of the door with a table saw and then cut off the side with the doorknob.This allows more room for the door to swing in and out without binding.

3. Sand the edges and add the paint and finish.

4. Measure down from the top,back corner and then up from the bottom corner.Make marks at 7 inches on the side of the door opposite the knob.Open the hinge leave and screw the door leaf to the side of the door

5. Screw the second hinge to the bottom with bottom edge of the hinge even with the marks.

Here is the article that explains the steps in detail  http://homeguides.sfgate.com/interior-door-swing-ways-95112.html

I really screwed up my title, when I said said "double swing doors" I should have said "double doors that are hinged" or something else. I actually hadn't thought of having them swing both ways until I saw those hinge Stick linked, and may yet do that. But my going in question is just about a pair of doors that are both hinged to allow movement of large item between the 2 rooms. Sorry, I knew what I meant....just didn't describe it accurately.

Fred, with your French doors, and without a threshold you want to do a search for an automatic door bottom. These door bottoms are suitable for applications without thresholds. When the door is in a closed position, the device drops down and creates a seal, as soon as you pull the door open, the seal retracts.

Here is a link to some auto bottoms, for an example.

Man' I'm learning a lot...never heard of the automatic door bottom. Very clever.
