OSB, Rockwool, and Vapor Retarder
大家好，这里的新成员有一些问题，我敢肯定，您的伙计们很容易。我会尽力而为。
I air-sealed my stud bays in the garage and will use tape on the smooth side of the OSB horizontal joints before insulating, will Zip tape work well long-term for this? (Interior, smooth side of the exterior sheathing). Garage will be conditioned on days of excessive heat or cold + excessive humidity w/ a mini-split.
车库中的内墙也将是OSB（除了通往家里的墙壁除外）。我本来要使用牛皮纸脸上的R-19玻璃，但现在正在考虑R-23 Rockwool。但是，我在马丁的树林脖子上，所以我想如果我做岩圈，我现在需要处理蒸气屏障？如果是这样，建议什么？
Hand-in-hand w/ that is whether or not one can just use a vapor barrier primer on the smooth side of the interior OSB I’m going to hang to achieve this? I have “read” that painting or priming an entire wall of OSB is not recommended…
If a barrier is needed, is the rockwool worth the extra effort to do both steps instead of just using the kraft-faced R-19 in one step…?
谢谢你们。如果您需要澄清，请询问。

嗨，里诺，欢迎来到论坛。
马丁·霍拉迪（Martin Holladay）有几篇文章对您的录音带问题很感兴趣。他们很棒，因为他们探索了很多选择，其中有些在您的情况下可能更有效，更便宜。//m.etiketa4.com/article/return-to-te-the-the-the-the-backyard-tape-test
当你说“Interior walls in the garage will also be OSB (except wall leading to home)“, do you mean that you’ll be hanging OSB as a replacement for the drywall? That is, OSB will be on the interior walls of the garage?
嗨，布莱恩。
Yes, 3 of the 4 interior walls in the garage will be OSB. Drywall on the ceiling & on the wall joining the house.
这是您所需的墙设计信息：

谢谢你。我读了它，但是它没有具体回答我的问题...

Additional reading has not clarified the issue. Some are saying in zone 5, you need a vapor barrier like membrain over the rockwool, on another site I saw this statement "Because of its greater density and water resistant properties, mineral wool acts as a vapor barrier and, unlike fiberglass, does not need an additional vapor barrier to be effective."
需要明确的是，车库将根据需要通过迷你切片加热和冷却，OSB外墙，不知道那是什么和乙烯基壁板。内部侧壁也将是OSB，天花板将是干墙，其上方有R-38密集包装的纤维素（车库上方的空气密封和绝缘奖金室），隔离房屋的墙壁也被干燥。
因此，我仍然不知道在这种情况下是否需要蒸气屏障，或者有什么好处...
我意识到您的问题是特定的，但我确实认为您应该阅读本文中,五个墙工作。它将阐明您的一些与控制层相关的询问。
Thank you, looks like I need a membership or something to read it though...
我想说的是，如果您使用Rockwool，请使用智能蒸气延迟器，例如膜（并且，我也会和Rockwool一起使用更高的R-Value）。
也就是说，我认为，如果您在空气密封护套的情况下省略了蒸气延迟器，并且有乙烯基壁板，那么您的墙仍然可以工作，固有的乙烯基壁板可以使护套变干，好像它有大雨一样。另一个有助于
is that this is a garage, so it likely won’t see the moisture loads that a usually occupied space would see.
These are all assumptions of course, and any one or all could change in the future, which is why I’d probably include the smart membrane if it were me.
再次感谢，布莱恩！

Table 2A. Say that your exterior layer (just OSB?) wet perms = 4. This leads to a Class I interior side vapor retarder in Z6 and a Class II in Z5. Say that interior layer OSB dry perms is 1.5. In this example, you are OK in Z5 but not in Z6.
空气密封内部是一个好主意。
嗨，乔恩，
我看到了，我只是不知道湿per湿的幽默是如何弄清楚的，以前从未做过。
有关信息，这是摇滚技术人员对蒸气屏障的反应：
“ Rockwool是一种蒸气的开放产品……空气和蒸气可以缓慢地通过它扩散，因此不会充当空气或蒸气密封。”
而且我用胶带，一些胶带凝结泡沫和np1填缝，取决于被密封的内容，我的空气密封了...
Thanks for all the help. I went with Rockwool & Membrain...
