不锈钢闪光以进行外层地下室绝缘
你好，
我希望用4.5英寸的EPS隔离地下室。这是一个改造应用程序。它是在加拿大北卡罗来纳州哈利法克斯（我相信6区）。
I’m looking at stainless steel L flashing with drip edge. Stainless for durability and appearance as the house is about 1000ft from the sea and we get a fair amount of rain even in the winter. We also get a fair amount of snow too.
(1) What is the minimum gauge of stainless steel you guys would recommend? The 2010 Canadian building code requires a minimum of .33mm (13 thou) for galvanized steel for flashing. That’s thin for galvanized. It doesn’t say anything about stainless. One good link from SSINA (http://ssina.com/download_a_file/foring.pdf) says you can use a thinner gauge stainless than galvanized.
(2) How do you join the flashing end to end? Does each piece have to be mechanically fastened to each other or can I use sealant to seal the seams between pieces. How do you account for expansion in the joining?
（3）什么是粘附闪烁到混凝土的好方法。我们在新斯科舍省没有白蚁，但是有木匠蚂蚁。我想通过将其连接到混凝土墙的顶部，也将其用作错误保护。同样，这是改造的，所以我无法将其插入泥泞的台面。
Regards,
韦斯

Basic overlap joints is what most do this way. As to thickness, you just need to be thick enough to deal with oil canning... Go to where you are buying it.. and sample.
Go to a home or contractor that you like the install and copy. I have done so my whole career. Ask and yee shall receive.
至于不锈钢，我现在是Adirondacks周围湖泊上的码头硬件的用户。码头的第一部分是硬件。木材可以持续到我们建造的2-5倍的方式，就像硬件一样。
韦斯ley: will be looking forward to the info you can find here and there ..
我在魁北克中心，我们也有“辐射”鲤鱼的问题
( because they have only so short time to thrive )
并且仍在寻找合适的蚂蚁/虫子在绝缘/墙壁的底部闪烁...
Do you wish extend the SS flashing pass the 4.5" EPS ?
韦斯ley,
很少使用不锈钢闪光的原因有很多。与铜不同，它不能在现场焊接。（可以焊接不锈钢，但这很棘手，而且我从未听说过不锈钢在田间焊接。）也很难切割。
感谢您的答案。在发布之前，我可能应该做更多的研究。
FYI: I talked to a sheet metal shop. They never go under 24gauge because SS or galvanized crinkles on them. Stainless steel is about twice the cost of galvanized from what they quoted me. It was just over $600CAN for 125feet of 2" x 5" L 24gauge flashing vs about $300 for the same galvanized.
吉姆，
是的，我想将SS扩展到EPS上方以进行滴水边缘。我刚刚得到了l闪烁的快速报价，以了解一个主意。我将在发现的内容上更新此主题。我要弄清楚了几周。
马丁，
谢谢。我想到了铜，但认为这会更昂贵。我以为错了。我打电话给金属板店，铜实际上更便宜。铜与水泥兼容吗？我想贴在水泥上以提供昆虫屏障。
韦斯ley,
Q. "Is copper compatible with cement?"
答：请参阅本文在铜开发协会的网站上发布（一个小组不想在不正确地使用铜时看到任何故障）：Is There A Problem With Embedding Copper Tube In Concrete?
How could concrete be a problem to coper if you are going to use adhesive/caulking ?
铜比镀锌便宜吗？他们将使用什么声音？
关于昆虫，我很难找到针对Google上的蚂蚁“闪烁”的建议的“形状”。
Any hint as to what kind of shape makes it impossible for carp ants to crawl pass the flashing ?
斤，
Caulking is not perfect so I want to be careful. They didn't specify a gauge for copper they talked about ounce. I forget now what they told me for ounce.
我认为没有建议的形状。屏障仅是为了防止虫子从绝缘材料中潜入木头上。它迫使他们进入您可以看到它们的外部，以便您知道自己有问题。对于白蚁来说，我在这个论坛上听到其他人说，他们有点被日光吓倒了，但我认为木匠蚂蚁的情况并不一样。
What do you mean caulking is not perfect? nothing is..but don't you only wish for the flashing to be correctly positioned and caulked here ?
There must be a specific shape/dimension that carp ants cannot cross phisically.
Usually if the colony cannot easily reach ground to nest, they do not set there.
Don't worry ..they have no problem going around in daylight at all :)
（我不止一次出没，他们确实爱EP）
金，我一直在这里处理木匠蚂蚁的侵扰。他们将绕过任何基本闪烁，并在结构中找到另一条路线。我从未见过一种成功的机械方法来阻止它们。用硼酸盐喷雾（例如田叶滩）治疗是必经之路。
In the past when we used a 50 year galvanized flashing, we had them break the inner flange down (at least an inch for anchors) a bit under 90 degrees so water drips outward and the outer flange downward a bit more than 90 degrees so the drip edge (half inch) is outwards. I've used a peel and stick type window flashing on the inner flange (to go against cement, seal and hold it in place). Then it's easy to lift up the 4-6" flashing and screw to the wall. Overlaps are about 2" and you can hardly see them when looking down the wall.
I'm sure SS will work and look fine as well. We use a lot of it on our fire truck builds along long edges/corners. You can choose brushed, polished or plain. S/S is also a low conductor which is nice.
干杯，
PK
斤，
Just being paranoid. I don't want the copper to touch the concrete. I think though a peel and stick membrane would work for that.
我发现了另一篇有关蚂蚁的GBA文章：//m.etiketa4.com/blogs/dept/qa-spotlight/coping-termites-and-carpenter-ants。我想你看到了那个。
Here's another article on carpenter ants from a pest control company:http://unexco.com/carpants.html。
Paul,
谢谢。我可能会和铜一起去。对于SS，您可以用航空剪剪下24Gauge吗？想知道您将如何在外部角落内做？只是好奇。
I wanted to do both a bug guard (J channel) and z flashing for the wall. They'll get expensive with copper or SS. Wondering if I can have a very small z flashing that drips on the J channel if the J channel slopes down? That doesn't feel right though.
I was doing wiring lath with surface contact cement so maybe I can bring that up to cover top of foam. That would provide barrier for the ants. Some more thinking to do.
如何阿布t a rust proofing paint or coating over aluminum or galvanized? I may look into that. More labor intensive but I could do that myself.
实际上，我使用了一款出色的当地加热/冷却装备，该装置能够订购库存宽度并使用其制动器（机器弯曲长块...对不起，我在上面使用了“ Break”一词）。他们为我做了10英尺长的部分。S/s是非常延展的剪切/切片的痛苦。

韦斯ley, If the flashing is just for insect control I wouldn't use an L flashing. I'd use perforated stainless steel bent to a U. That's what we use here in BC for rain screen base flashing whether there is foam or not.
