So, just to be sure, Tyvek is not needed with the Zip system? Just tape the seams and you're done?I have used it many times and it is very good , I live in Mass. on an island and we do not need T&G to meet the 110 mph code . The stuff is one of the better things to have come out in the last few years . We also use the zip wall and roof system as an air barrier for energy efficiency. So we are getting double bang for our buck
The book says cut a 2" x 2" piece of tape and stick it on the penetration point. After 10 minutes the tape bonds to the surface material and you're done.what happens if you are sheathing a 12 pitch and you put cleats all over the place? follow-up with tar?
what about nail heads?
nevermind, they want you to tape the holes.
This material will wick water. It's an Advantech product, but doesn't share the same water resistant properties as their T&G decking. Probably has something to do with the bonding of the surface layer.DO NOT let the product get wet. I had some Zip Wall wick water along the ground and the wall was WaVy like crazy - I will see if I have some pictures. On a 16" o.c. wall the zip wall would bow or cup up to 3/4" in between the studs. Thankfully I was matching an existing old house that was already all wavy and tilted. It matched almost perfectly.
