Most effective door weatherstripping?
So, for blocking little air leaks around the perimeter of the door slab: of the typically available options–the felt stuff, the foam tape, the molded plastic fin stuff, the teardrop-shaped stuff, etc.–what’s the best plan of attack? What’s useless?
I’ve got some of that typical compression door seal stuff (whatever it’s called) installed on the jambs, and there’s a triple-seal sweep already installed, but it’s not really close to perfect yet.
I’ll also be installing it around my vent panel.
For what it’s worth, I have indeed looked at this:
(Didn’t see this covered when I ran a search, but, y’know….)

a few thoughts:
magnetic stripping is easy & very effective - obviously, doors must be metal;
outswinging where bottom face of door closes againt raised threshold allows effective seal all around;
soft-spongey stuff is effective, but often compresses too much and allows "anti-pick" feature on keyed locksets to engage in keeper;
nail-on stuff subject to temperature change - less flexible when cold;
sticky-backed stuff not consistently permanent enough;
I think you can get acceptable performance from the Q-lon type weatherstripping, but the door and jamb have to be perfectly in plane with each other, which is often not the case (especially a few years later). If you want to knock it out of the park, install a three-point lockset on your door, so it will always be tight to the weatherstripping when closed.
