instructions on interior polyiso board?
斯蒂芬·埃奇（Stephen Edge）|Posted in一般的问题on
有人可以告诉我如何安装内部多丽莎板吗？这是新的2×6结构。可能会在多丽莎（Polyiso）后面的墙壁上使用羊毛瓦片隔热材料。谢谢，史蒂夫

斯蒂芬，
您的问题有点模糊。
If you want to install interior polyiso, your thermal weak points will be partition intersections and rim joists, so you need to come up with a plan to address those areas.
Use only airtight electrical boxes on your exterior walls. Be sure that your electrical boxes are mounted correctly to account for the thickness of the polyiso.
切开面板以适合并用帽指甲固定。将接缝胶带胶带以保持空气紧密度，并根据需要在电盒和穿透处进行空中密封填缝或泡沫。
关于悬挂石膏板，您有两种选择：
1. Strap the wall horizontally with 1x3s or 1x4s so that the drywallers are screwing the drywall to the strapping.
2.用长螺钉将干墙通过泡沫连接到螺柱。
Thank you for the reponse Martin. I
-I'll use plywood extensions for my airtight electrical boxes on your exterior walls.
- How many layers do people typically use and how many inches per layer? Foil facing the inside I assume. Staggered joints too.
- 我应该瞄准哪个品牌？有关系吗？
- 请阐述绑带的用途，因为我使用长螺钉将石膏板固定在螺柱上。空域仅用于更多的R值？我担心老鼠会进入那里并建造公寓。
史蒂文，
Q. "How many layers do people typically use and how many inches per layer?"
A. One or two inches is fairly common, although there is no technical reason (other than issues swirling around the current "cold OSB" debate -- and if you are interested in that debate, seeHow Risky Is Cold OSB Wall Sheathing?）您无法使用较厚的泡沫。
如果您确实选择安装一层以上的泡沫，请记住，除非您安装了水平的内部绑带，否则在超过2英寸的泡沫上安装干墙可能很难。
问：“我应该瞄准哪个品牌？”
答：您想要的任何品牌。
问：“请说明绑带的用途是什么用途，因为我使用长螺钉将石膏板连接到螺柱上。”
A. Drywallers hate installing drywall over foam. It's hard to hit the studs. And in some cases the drywall can be a little spongy and you might have more screw pops.
I've used the long-screw-through-foam method, though, and I know that it works.
Q. "Air space for more R-value only?"
答：不仅是R-Value - 尽管您将获得另一个带有箔面空间的R-2或R-3 - 而且要更加安全，更容易固定干墙。
One final point: most energy experts prefer to see rigid foam installed on the outside of the wall rather than on the inside. But I assume you know that, and you have your own reasons for preferring to install foam on the interior.
Martin: "I've used the long-screw-through-foam method, though, and I know that it works."
Steve: So I'll plan on doing one layer of unfaced 2inch thick polyiso board with no strapping and the long screw method, with the only down side being, it's tricky to find studs
马丁：“冷OSB”辩论
史蒂夫（Steve）：我决定花700美元，然后和100％的胶合板一起去我的家。
Martin: "One final point: most energy experts prefer to see rigid foam installed on the outside of the wall rather than on the inside. But I assume you know that, and you have your own reasons for preferring to install foam on the interior."
史蒂夫：我正在用气密干墙在我家中使用气入口和易碎的爆炸。我的她的身影会很冷，但会干燥。希望我的理论泛滥。
Q: what do you think my R value will be using 2x6 filled with wool + 2 inches of Polyiso? Would foil facing buy me anything for this application?
Thanks!
问：“您认为我的R值将使用2x6填充羊毛 + 2英寸Polyiso？”
答：羊毛隔热材料的R值为每英寸3.9，因此5.5英寸将为您提供R-21.4的中心bay R值。我猜测，穿过螺柱的热桥将您的R值降低到R-18或R-19-只是一个猜测 - 而2英寸的Polyiso将使墙壁R值达到大约R-31或R-32。
但是，除非您在这些位置提出仔细的细节，否则您的边缘托梁和分区交叉口会严重降低您的墙壁性能 - 这就是为什么外部刚性泡沫更喜欢内部刚性刚性泡沫的原因。
我应该使用什么样的刀和胶带？
我在旧的便携式桌子上切下泡沫，并用手锯和 /或圆锯进行小切口。需要将泡沫中的接头紧紧或左松开，并且可以用胶带将泡沫紧紧喷洒。与GBA的最佳长期录像带有关的讨论很多。我认为最高的工作需要框架和泡沫和密集的堆积隔热材料之间的声学密封剂。您想阻止墙壁组件中的所有空气移动，并且仍然在同一时间保持一个或两侧。
Sheet foam with a hole in it is R 0.
