   Coravent可以很好地工作，有点像塑料纸板，并且具有一些结构。许多人使用了塑料泡沫状的“山脊通风口”材料，这些材料也旨在在带状疱疹下捣碎。那个塑料泡沫像山脊通风口一样皱着眉头，但它使雨屏通风口间隙漏洞的材料变得不错 - 不要将其粉碎。

   Thanks, Bill. Seems like ti would be very expensive to use coravent behind all the open joints, is that what you're advising?

   沃尔特,

   开放的关节壁板就是这样。它不能提供任何防止昆虫侵扰或针对元素的保护的保护，我不确定您实际上可以添加这些属性而不会损害外观 - 这是首先选择开放关节的唯一原因。

   Open Joint siding isn't really a rain-screen in the sense that most building scientists (or our building code) would describe one, and the walls need to be detailed in a different way, so that the layer behind provides all the water shedding details of a WRB layer, but also gives the primary layer of protection we usually rely on cladding to provide. If I was using it, my preference would be to go the other way and make it as open as possible to discourage insect nests and make it easier to periodically clean the cavity.

   沃尔特,

   您只需要一小部分材料，而无需脊式通风口的全部宽度即可。

   The rolled ridge vent material that looks like a scotch pad is easier to work with for this. Just cut it into 2" wide strips.

   Thank you, Akos. I feel like it would be easier and cheaper to staple a full 5' wide roll of aluminum or other durable window screen over the entire furred facade before installing the open joint siding?

   沃尔特,

   The best is a perforated U mold that is the same width as your rigid insulation+rain screen.

   I've done the stapled window screen, it works but takes a bit to get right. Easiest is to staple it to the bottom of your WRB at a height where the strapping would overlap it about 3" then install the strapping.

   Windows屏幕上没有插入孔，也没有山脊通风口的材料和更多的安装工作。在施工过程中也很容易损坏。

   再次感谢。我的问题措辞不好，所以我已经编辑了它。我实际上是指墙壁的顶部或底部，而是指打开的接头壁板安装中的壁板之间的开口接头。谢谢你的耐心。

   我最初以为您在询问在普通雨屏设置上筛选顶部和底部通风口。对于开放的关节壁板，珊瑚脊或泡沫脊排气材料都无法正常工作。

   I can think of two good options for you:
   1-更昂贵，最耐用：获得小网格（小于1/8英寸的网格开口）不锈钢硬件布，将其与床单边缘之间的重叠放置，然后将壁板固定在硬件布上。316不锈钢将提供最佳的腐蚀保护，但要花费最高。304也可以，而且便宜一点。
   2- much less expensive, less durable: put fiberglass window screen up, overlapping edges between sheets, then fasten the siding over the window screening.

   Don’t use aluminum or galvanized screening since either will rot after a few years of exposure to the outdoors in this application. You may have some issues with debris accumulating between the screening and the back of the siding boards too, especially if you don’t get the screening stretched tightly before installing the siding.

   Hi Walter -

   我的建筑师好友史蒂夫·巴切克（Steve Baczek）（http://www.stevenbaczekarchitect.com/info/) does a lot of open joint wall cladding systems and he swears no insect problems without any bug screen system.

   几周前，在维加斯的国际建筑商节目中，本杰明·奥比克（Benjamin Obdyke）拥有一个光滑的新开放关节雨系统。

   I THINK the new system is in addition to this one:http://www.benjaminobdyke.com/uploads/resources/FWUV_HFUV_Sell_Sheet.pdf, but I am checking on that.

   Here is the new Benjamin Obdyke open-joint rainscreen system, available starting in April this year:
