Batt Insulation Tape

I'm installing kraft faced insulation batts in the walls. I understand current codes/recommendations is to face-staple the tabs to the face of the studs to create a solid vapor barrier.

For batts that are cut and don't have the tab, what kind of tape is recommended to seal the kraft paper to the neighboring stud?

I've read to use foil hvac tape, but it seems odd... Though it won't be seen under the drywall, I'd rather do it right.

I don't see that level of care taken very often, but I have seen kraft package tape used (probably the wrong thing to use) and foil hvac tape (meets astm testing).


If a piece needs to be cut to width you can often leave the paper long, cut the insulation back, and still staple the paper to the face. Or just rip to width and use the tape as your flange.
