Insulation without drywall?
区4C
Using kraft faced fiberglass insulation, is it safe to insulate an exterior wall indefinitely without Sheetrock/latex paint?最终表rock will go up, but wanted to keep the house warm for winter in the meantime…
我了解干墙和乳胶涂料是一种蒸气延迟器，但我也知道Kraft Paper的限制额定值为1，这应该意味着它会使霉菌避免使用模具，对吗？
No rigid foam on the outside in this application, and there isnt any siding up quite yet but within a month or two there will be siding up on this wall and it will be vented. And currently there is tyvek housewrap.
To give this a little more context if it at all helps, I tried doing this same thing with another room but used un-faced mineral wool w/o Sheetrock for a while, and after only a few weeks I pulled out the batts to see what it looked like and sure enough, mold had started to grow. So trying this sort of thing without the Sheetrock makes me a little nervous, but hope my method this time around is smarter.
任何建议都感谢。
Thanks.

I think you’re ok, but you could temporarily stable up a sheet of poly to act as an air barrier until you have drywall up. Just remove the poly before you put up the drywall. The other option would be to install a sheet-type smart vapor retarder like membrain over the wall which wouldn’t need to be removed before installing drywall.
The Kraft paper is a vapor retarder, but it’s almost never sealed very well. I wouldn’t rely on the Kraft facing alone, especially when there is no drywall to keep the edges pressed tight to the studs.

我本可以在我的原始帖子中提到这一点，但现在似乎更有意义：我打算在干墙/油漆之前用矿物质羊毛代替牛皮纸面对的玻璃纤维绝缘材料。当然，我不想将玻璃纤维放入以后的意图上，也许有一种安全的方法可以隔热带有矿物质羊毛，而不是在干墙/乳胶涂料之前的几个月内脱离隔热材料阶段。这是我的想法，您的想法：
您提到了膜的东西...让我想到了，所以我在车库里看了一眼，发现了一个通常用于硬木地板下方的牛皮纸的杂物纸。您是否可以在未透明的矿物质羊毛上使用这些问题，而不是膜，而不是膜，可预见的将来，没有干墙和油漆。这会很好地避免模具吗？我可以轻松地使用膜，我听到您在说什么，但是如果这些东西只是躺在周围，我认为我可以节省几美元。
To me it seems this seems ok since i'd be up to code at that point - the code that says class I or II VR in marine 4.
如果是这样，如果我在正确的轨道上 - 一旦我要放置干墙并用乳胶涂料进行油漆，在同一墙壁组件中有2级II类VR是否会造成任何伤害？换句话说，将纸张放置，还是在之前将其撕下？（4C中的代码表示III类允许带壁板。）
I don’t see any issues using the Kraft paper if it’s rated for the purpose. It won’t be much different from using paper faced batts. The most important thing for you in the temporary setup is to have something there to act as an air barrier before the drywall goes up.

可以很好地提醒您，从内部到护套，然后回到内部的气流会造成水分问题。内部侧屏障很重要。
It will also help to keep interior dew point as low as possible.
凯文，
牛皮纸面玻璃纤维不是空气屏障，因此您仍然可以在护套上霉。您的护套会多发？答案取决于室外温度（较冷的温度=更多霉菌）和室内相对湿度。

马丁，您认为牛皮纸的大纸至少会暂时用作空气屏障吗？我的理解一直是，卡夫（Kraft）面对的瓦特（Batts）并不是空气屏障，因为边缘从来没有真正密封，所以有很多差距。如果放上一张大的一张牛皮纸纸，几乎就像房屋包装纸一样，我认为如果紧紧停滞和/或填缝，它将更像是空气屏障。
诚然，我从来没有尝试过，通常在这样的应用程序中需要临时空气屏障，通常会使用多板。

您还应该注意，正在建造的新房屋中内置了很多水分。混凝土，木材，在房屋干燥之前潮湿/潮湿的所有东西现在都将试图干燥，空气中的所有水分都将朝着寒冷的护套前进。您如何加热空间？希望您不要使用燃气的“ Salamander”风格的加热器。它们增加了大量的水分，更不用说燃烧的有毒产品了。
如果您想最大程度地减少护套上的冷凝和霉菌生长的风险，则可能要除去内部空气。对于您的条件，干衣机更好。

如果我们谈论的是带有外部和内部墙壁内部的浴室墙组件，是否有任何更改？浴室墙壁组件是否需要在内部与外墙之间有所不同？我也想在浴室里使用矿物羊毛...
使用VR涂料或底漆是一个好主意，还是在普通PVA底漆上仅仅是有光泽的乳胶油漆？
