It blows to have a drafty door

[Starsexplore]

Hello,
I am considering replacing a poorly-sealed interior door that connects to an uninsulated garage. Weatherstripping doesn't seem to be enough, plus door is hollow-core and the area seems to be thermally inefficient. Door opens outward into garage, and replacement must also open outward. Does anyone know of a good fix? Thanks in advance! :beer:

Out here the code calls for an exterior door to be installed here. Your big box store or window and door company can help you out with the order, tell them if the wall 2x4 or 2x6 out swing with self closing hinges. Then you have to figure out left or right.
It comes with frame and sill. Not cheap.

Yeah, that's what I was afraid of.... sounds like there is no easy/cheap fix. Thanks!

Any used building material stores in the area? Run a want add.
