磁带，磁带，磁带
I’m about to start putting up continuous exterior insulation on my walls, with seams taped as the primary water barrier (primary air barrier is a membrane behind the foam, though.) Due to supply chain issues, the polyiso foam I ended up with is Johns Manville AP Foil Faced, which is specified for this purpose per their instructions (https://www.jm.com/content/dam/jm/global/en/building-insulation/files/files/bi%20toolbox/bid-0150-residential-residential-residential-ap-foil-ap-foil-above-goil-above-grade-grade-grade-grade-grade-grade-grade-grade-grade-grade-grade-road，-9.10-9.10。13.pdf）
引用该文档的第一页，他们建议“闪烁的磁带，例如3M 8067，Grace Vycor Pro或Lamatek”
引用BSI-067（https://www.buildingscience.com/documents/insights/bsi-067-stuck-on-you）, Joe Lstiburek says:“大多数丁基磁带通常称为“闪烁”磁带，丙烯酸磁带通常称为“护套”磁带。丁基胶带“更厚”，背面是“粘糊糊的”。丙烯酸胶带很薄。丁基胶带比丙烯酸胶带更好地处理运动。丙烯酸胶带更好地“粘” - 它们令人难以置信地粘贴。丙烯酸胶带通常用于“终止”丁胶的顶部边缘。这是必要的，因为丁基胶带可以钓鱼（随着时间的流逝，它们的顶部边缘剥落或滚开），因此它们的顶部边缘需要“终止”。没有发生这种带有丙烯酸胶带的鱼类。尽管大多数闪烁的磁带都是丁基，但丙烯酸技术的进步使有限数量的丙烯酸磁带可以用作闪烁的磁带和护套磁带。”
3M 8067 is acrylic-based and sold as a flashing tape — apparently one of the “limited number” that Lstiburek refers to?
Grace Vycor Pro is butyl-based and sold as a flashing tape — per Lstiburek, using this tape woudl require terminating the top edge with an acrylic-based “sheathing tape”, though the Johns Manville instructions don’t mention this.
Lamatek似乎是各种胶带相关产品的制造商，而不是特定类型的胶带。
我的空气屏障膜是Adhero，我的内部蒸气延迟器是Intello，所以我还使用了许多proclima磁带 - Tescon Vana和Contega Solido Exo，它们是基于丙烯酸的，仅以“磁带”出售。他们也很昂贵。
So, I’ve got foil-faced polyiso (which, according to some of martin’s old articles, is generally one of the easiest substrates to stick to.) The foam manufacturer is recommending an acrylic-based flashing tape, a butyl-based flashing tape, or a manufacturer of tapes. It feels like the Proclima acrylic-based tapes would probably work fine. It also feels like I should use something directly mentioned in the foam instructions so the building inspector doesn’t have any question about it. Of those choices, the 3M 8067 is acrylic-based and thus (per Lstiburek) shouldn’t need any special treatment at top edges — and is also a fair bit cheaper than Tescon Vana. Is this a reasonable conclusion to go with?

自BS文章写了以来，已经发生了很多变化。如今，丙烯酸磁带更容易获得，其中许多磁带（Zip，8067，Siga，Pro Clima）确实很好地工作。
>感觉基于丙烯酸的磁带可能会正常工作。
Probably. Like you said, though, expensive.
> It also feels like I should use something directly mentioned in the foam instructions so the building inspector doesn’t have any question about it.
如果您的检查员正在检查此详细信息，我会印象深刻却很烦恼！

8067 is a great tape and readily available on Amazon. I would not hesitate to use it. My house has many football field lengths of it all over the place.
+1 on on the 8067 tape. I have also used it to tape 1.5" JM polyiso with the foil face, and at this point, I'm certain that removing the tape means removing the polyiso facer with it.
FWIW I also used a foil faced tape, Nashua 324A, available from HD and pretty much everywhere, and it worked great. It is also an acrylic based tape, with a backer, and once in place and rolled it doesn't appear to be removable. The service temperature is stated well within my normal range, -20°F to 325°F. I wouldn't hesitate to use it either. It's also cheaper than 8067.
跟随-up on this for posterity:
我继续订购了一堆3m 8067，它运行良好。我使用3英寸的接缝胶带，将4英寸切成正方形的螺丝胶带，在螺钉上4英寸（因为后背在中间拆分，而3”有一个狭窄和一条宽条）和6英寸的外部角落。一些快速笔记 / A录音带的评论：
-This stuff is sticky! There's no room for error -- especially with the (quite weak) JM AP Foil Faced facers (which tear if you look at them wrong) -- if the tape touches the insulation anywhere, it's basically stuck; I'm confident that it's not coming off.
- 这也有点臭 - 我不建议在室内使用它，但是在户外就是这样。当UPS女人送出一个案例时，她评论说：“我有一个包裹为您。它是胶带。我可以闻到它的味道，它一直在刺我的卡车！”Proclima磁带也有轻微的气味，但不如8067强。
- 这有点弹性 - 尽管最好在需要伸展之前先进行伸展之前进行预脱毛，否则它会弹回的趋势。
- 我对此最大的抱怨是，支持者很容易（比Proclima支持者更容易），因此，您正在长时间工作，而支持者会在中途撕裂，而您需要获得，您需要获得。您的手指向后胶带重新启动。
- My other complaint has nothing to do with the tape, and everything to do with the insulation. The JM AP Foil-Faced comes with little lines molded into it to make it easy to cut into 16" or 24" widths -- but since I'm applying full panels on the exterior, these just get in the way and make a lot of little channels behind the tape. The 3M tape's flexibility helps with this, as you can kind of press it back into the channels, it's just annoying and doesn't inspire confidence.
- 根据记录，Proclima磁带也可以很好地贴在Polyiso上，我想我想我一般都喜欢它们，但是8067的价格是一半的价格，而且做得很棒。
概括：我会再次购买 /使用3M 8067胶带进行外部应用。但是，我不会再次使用JM AP箔纸 - 面对面太容易受到破坏，无法激发其对WRB的长期能力的信心。（而且，无论您的仔细剪切和真空，少量泡沫碎片最终到处都是 - 我想这是矿物羊毛或木纤维绝缘的另一个优点，最终在院子里的碎屑是“岩石”或“木头”不是“塑料和箔” - 但这是另一个故事！）
我在内外使用了8067英里的8067英里 - 可以证明其耐用性。即使暴露了几年，它也可以完美地保持。
是的，其中一些磁带非常臭，尤其是当您积极使用它们时。我真的不知道为什么，但是在您使用磁带后，气味似乎并没有持续很长时间。
我喜欢将nashua 324a胶带与polyiso一起使用，因为它与箔纸脸相匹配，并在使用时呈箔纸面对面的坚固墙（可能是我的工程师的OCD部分:-)。您真的不需要这里的箔胶带，但是在面对的Polyiso上看起来确实不错。
顺便说一句,你必须打扫保利Johns Manville)iso to get the tape to stick? I just recently (a few days ago) did a small project with some of this polyiso, albeit polyiso bought several months ago, and I found it had very thin layer of oil-like material on it which I assume was a release agent from the manufacturing process. The tape didn't want to stay stuck until I wiped the areas I was taping with isopropyl alchohol prior to taping. Once I cleaned the surface, the tape stuck like crazy like I was expecting.

Huh, I haven't seen any issues with anything oily on the surface -- for me, if the tape lightly touches the facer, the facer's coming off with it most of the time! The only thing I've had to clean off is all the dust and crumbs from cutting it, which like to cling to the surface and prevent the tape from sticking -- I just brush it clean with my hand before taping.
Now that you mention it, taping with foil tape would be satisfying! But, I already have a case of 8067 and it'd be very un-satisfying to switch appearance in the middle of the job ;)
我在我的上面有很多“仓库灰尘”，我不得不先去除那些黑色的烟灰状薄层灰尘。似乎只需要用湿纸巾擦拭边缘的边缘。
Mine as actually a very thin oily film. I noticed the sheets were really slick, and my fingers were slick after handling them. There was nothing visible, and it wasn't gooey or anything like that, it was just the very slightest film of something oil-like. Isopropyl alchohol took it right off, so it wasn't a big deal once I realized the tape wasn't really sticking the way it should. Acrylic tapes should normally stick like crazy to that foil facer.
