石膏板：传统，绿板，densarmor Plus，Aqua Tough
我们将在周三获得Sheetrock天花板盖。并隔热，因此我们可以开始干燥墙壁 - 我们所有的热量似乎都在通风拱形/山脊通风口上升。We had been thinking of spending just a little more and doing greenboard throughout to do a step above drywall as they claim but then realized I really don’t know if greenboard, DensArmor, Aqua Tough is really any better than traditional sheetrock/drywall for mold. We have not ordered it quite yet. I did not know if green board meant they add something (like fungicide or biocide, which I am not sure is healthy) to tout more water resistant or why the claims that it could be better. Then, we had thought we might try DensArmor paperless fiberglass in bathroom but then our sheet rocker says he prefers Aqua Tough (which looks like cellulose and I am not sure cellulose is a better option). Okay, what do I know:) …hoping you all can help us out We are climate zone 5/6 if that is important – N Idaho / Eastern Washington. 1) For all walls/ceiling (except bathroom): USG Mold Tough (aka their version of green board) or just stick with regular USG drywall? 2) For bathroom only: GP DensArmor Plus or USG’s Aqua Tough or just stick with regular USG drywall? (We will put Wedi board water proof system behind tile shower.)

Greenboard has only one face that is mold resistant, it’s not the entire sheet that is different from regular drywall. I use green board in skylight wells as a little extra protection against problems caused by condensation, But I wouldn’t trust it as serious mold proofing if you have substantial moisture issues.
It sounds like you need to do some extensive air sealing. If your ceiling is open, you probably have access to things like top plates. Make sure to air seal everything while you have access!

我了解这一点，比尔 - 但是，绿色板上的“面对面”是什么独特的，以使其能够要求防水呢？
例如，所有绿色板（例如USGS模型）是否包含杀菌剂/杀菌剂 - 是否添加/与众不同，以使其具有绿色板和防水性？
Thanks, Bill!
老实说，我不知道细节，我会查看USG数据表的信息。绿板通常用于可能看到更多水分之类的水分等区域。我在天窗井中使用了它，因为这些区域有时很容易凝结。在这些位置，绿板更耐用，但只有一点。
To add to the comment about using 5/8” drywall, it also helps with sound and preventing any sagging in the ceiling between joists. I built the ceilings in my own house this way for exactly that reason.

哦，比尔，你还能向我解释什么是顶板？以及如何在石膏板前扎下它们？（我们有2x6墙，带有能量治愈的桁架。）
I did a real good job on slab on grade foundation and walls air sealing wise but couldn’t figure out air sealing ceiling well enough to explain to my husband unfortunately.
顶板是横跨墙壁顶部的水平框架成员。顶板基本上是墙壁的顶部。这里有很多有关空气密封此区域的信息。基本思想是密封用于接线和管道的孔以及任何间隙。罐装喷雾泡沫通常使用。我建议阅读一些有关阁楼空气密封的文章，这些文章通常会详细介绍有关该墙壁区域的详细信息。

I do not think you need or want green board for your main ceiling, in your bathrooms Ok. Green board is less likely to disintegrate should it get wet ones or twice. The best way to avoid mold is to keep your house dry. Given enough moisture mold will find something somewhere to live.
如果您的托梁位于中间24英寸，并且计划在干墙顶部进行超过R38，则可能需要选择5/8。

杰米，
I agree with Walter. If you care about mold prevention, there are several things you can do, but specifying special drywall isn't one of them. The keys to a mold-free house are (a) making sure that your interior relative humidity stays in a reasonable range, (b) never installing or using a humidifier, (c) using bathroom exhaust fans when taking a shower or bath, and (d) maintaining good housekeeping practices.
我在底部安装Densglass基地的一部分ment wall where there were previous water problems. The water problems were fixed, my thinking was in case there is a very big rain storm storm and some water makes it past the waterproofing, the drywall won't come apart and the wall can be dried out. For areas that should not never see water, doubt it adds any benefit.
Extra drywall money is probably best spent on 5/8 drywall and some insulation between the bedroom/bedroom and bedroom/bathroom partitions.
如果是我的房子，我希望我的石膏板不要耐湿。您想尽快知道任何水分问题以解决源头。即使您的石膏板没有损坏，它后面的任何框架也可能是，您也不希望发生这种情况。另外，良好的油漆可以更好地防止偶尔的水溅出墙壁。
