COR-A-VENT：宽度减小？
Cor-A-Vent产品长3英寸x 48英寸。我需要整个3英寸，还是可以将它们撕成一半以1.5英寸的排气条？
这将安装在1.5英寸厚的岩木舒适板80上，螺柱上有垂直的毛发条。
Any feedback welcome from anyone who has worked with these before. Thanks!

菲尔，您可以在桌子上撕裂它们。我建议使用高质量的丙烯酸胶带将其连接到毛茸茸的条上。
谢谢迈克尔。使用您遇到的较小条带有其他问题吗？这主要是节省成本的衡量标准。
菲尔，I don't have a lot of experience cutting them down but I've done it once or twice. I think they will tend to sag, and may roll. Watch out for staples when you're ripping them. If you want to save money, you might find it less expensive to use metal window screening instead--cut it into 6" strips and wrap it around the bottom of the strapping.
Micheal,
Builders here moved away from using screen at the bottom of the cavity because it was too susceptible to mechanical damage - especially weeds or grass growing through it - and once torn can't be replaced.
我们使用穿孔的J-闪存，比Cor-A-Vent更难堵塞和更好地抵抗害虫。

Malcolm, you've mentioned that before--good point, and it looks like a good product.
Here in Coastal BC the lumberyards carry standard 1/2" and 3/4" profiles. They will also bend up wider ones to cover both exterior foam and the furring. Because the furring sits in the flashing it also makes installation easier.
Michael, I was thinking that the Cor-A-Vent would be nailed in place through the 1.5" Rockwool, so not much sagging. Maybe I'm missing something on how to install it?
菲尔，that should work. You might find that you want to pre-drill the Cor-A-Vent to reduce bouncing when hand-nailing. Framing gun nails would compress the insulation too much.
I was looking at the perforated J-channel as well. One worry I have is flying termites; the Cor-A-Vent looks like it would prevent access, but the J-Channel would allow it. But I like how the j-channel could cover both the furring strips and the Rockwool.
How would I integrate that with a Stucco weep screed?
菲尔，
J闪烁连接到护套上，仅延伸到您用于灰泥的任何底物（水泥板？）的背面。哭泣屏幕安装在基板的外部。
If you are worried about the size of the holes letting in pests you can get the same profile bent from perforated aluminum soffit material. If they can get through those holes, they can get into your roof too. We have flying termites here in the fall. I'e never seen one get through the J flashing, although sugar ants have no problem.
我有冲动将Coravent Rip Coravent成一半 - 在搜索互联网购买更便宜的产品后，我刚刚为我的项目买了一些。[但是，等等...您不是留下一半，不包括模糊的昆虫屏障吗？]
This product (the 3/4" thick version) cost me $85 for 60 linear feet, and a 60 mile roundtrip to pick it up at the dealer because it's not available online. But I simply couldn't work out an alternative that would be durable, easy to integrate, and actually work--the Coravent checks all those boxes. They're probably exercising well-deserved patent rights, but surely some other importer of plastic do-dads could come up with a competitive system?
谢谢大家。安迪，我没有考虑有关模糊昆虫屏障的那部分。我以某种方式认为它已整合到塑料中。
我还看到，为此目的，建筑商使用了Cobra通风孔（例如Cobra通风孔）等推出的脊排气产品，以适合毛茸茸的条。它负担得起且易于切割，可与公用刀搭配使用，看起来像是一种耐用的材料，可以使昆虫脱离空中通道。我很想知道这种方法的想法。如果有原因为什么这不是一个好主意，那就可以在这里分享。
Brian,
That might work fine. Two things I wonder about though.
当我在屋顶上使用类似产品时，我首先在山脊上钉硬件布以阻止啮齿动物。我想知道塑料网的耐药性如何？
用来阻塞腔的窗户屏幕损坏的主要来源是让草或杂草在壁板后面长大，然后将其拉出。再次，我想知道清除空间而不会损坏塑料会有多大的容易？
