I don't like Tyvek and I don't use any of the standard building wraps on my projects
0:05
It can't let moisture vapor pass through it. It's waterproof. It's kind of plasticky
0:10
And I can keep water out, but if water ever gets behind it, you know, on the wall side of it, it can't escape
0:17
So that's another problem and I've seen that happen. My preference is to use a heavier, breathable building wrap
0:26
It's made by a few different companies. Cosella Dorkin is one company that makes a product that I really like
0:34
It's probably about twice as thick as regular building wrap, so it's a lot stronger
0:39
You have a hard time tearing it. But most importantly, it allows moisture vapor to pass through
0:47
So it's kind of interesting. It stops liquid water. If there's a leak, it's not going to get through
0:51
But if water gets behind it, it can dry out through this stuff
0:56
So, breathability is a great thing
