Question on thresholds
Hi...I have an interior garage door that goes from the garage to a workshop with a step up into the workshop room. Workshop floor is concrete and room was not previously insulated, but I am having it insulated and would like to ask advice on what to use as a threshold for the door. There is no current threshold or sweep since it was only used for access from garage to workshop, without exposure to the outside. Any advice would be most appreciated!

Welcome to the forums! Since it is not subjected to weather, you wouldn't need a threshold. I would opt for a sweep if all you are doing is keeping out a draft from the garage, and keep heat/cool in the shop area. Interior door bottoms aren't slanted to act with a threshold, either.

I'd probably opt to put down a thin oak or aluminum threshold so that the sweep Larry mentioned wouldn't drag on the floor. It would give the sweep something solid to close against. It could also have a bulb seal on the bottom if you like, but you'd probably have to trim a bevel on the bottom of your door for it to seal just right, which is kind of finicky work.

Brant's right on the small threshold to allow the sweep to jamb against it when closed. Otherwise the sweep will drag on the floor. You could use one of the "broom sweeper" type sweeps without a threshold and it wouldn't have as much problem.

More threshold/sweep questions
Hi and thanks so much to all who replied!
I'm wondering how to affix a thin aluminum or oak threshold to the concrete--would an adhesive work, or do you all recommend drilling into the concrete? Also, don't think I've ever seen a "broom sweeper" type of sweep--would you mind describing that?

Check the hardware store for 3/16" x 1 1/4 or 1 3/4" tapcons. You will need the appropriate masonry bit, also sold with them... 5/32" if I recall correctly... and a hammer drill to drill into the concrete. Don't tighten the screws down too much or they will twist. Just make them snug.
A broom sweep has a thin row of bristles on it (like a push broom) instead of a rubber fin. If you can't find it at a hardware store, any glass shop that sells commercial doors should have one.

On those screws you will want to use the bugle style phillips heads, not the hex heads. If going into aluminum, you may need to buy a countersink, and ream out the aluminum so that the head of tapcons will sit flush. Same would go for the oak, you would need to contersink the wood so that the screw can seat into the wood without much pressure.
