Hello Hello, I'm in the process of building new, using site-built construction. I have double standing 145 studs, as well as standing 45 boards inside and out. I will be installing a vapor barrier before the 45 on the inside so that I can run the electrical wiring in it. My question is, how do I make it really, really tight, which I've understood is crucial when you have such thick insulation (45+145+145)? I have, among other things, a floor structure that must be passed through, how do I make it tight there? Where should the joints be placed, does it matter? The joints should be taped, with silver tape? Above all, it's the floor structure that concerns me...
Best regards,
Jaz

However, there is no age-resistant tape with age-resistant ADHESIVE, so also complement with a string of construction silicone!
You can never get the plastic through the joists, so you'll have to staple/tape between the beams as best as you can. I didn't care about this at all down to the lower floor - but I have a basement down there, so the plastic still ends at ground level!
