   哦，邮政编码和家庭滑动技术部门都表示，各自的系统不需要闪烁。每个人都知道我正在一起使用两者，并且窗户装饰为boral/pvc。

   克雷格，
   To me it's a two part question. If any of the following say you need flashing then you are hooped: Zip, the window manufacturer, your building code.
   查询的第二部分是建筑师在计划中显示的内容。如果在图纸上显示闪烁或指定，那么无论其他观点如何，这就是所管理的。未经批准，您将无法偏离合同图纸。

   搁置您是否必须对闪光进行改造，我认为包括这是一个好习惯。雨屏墙壁是根据第一层和第二层保护的原则来工作的。这个想法是壁板应该阻止散装水入侵，而第二层的WRB内层或在您的情况下，拉链是备份。应详细介绍内层，以尽可能将水分返回到外部，而不会保留在腔中。带有适当末端dams的头部闪烁就是这样做的。胶带闪烁依靠窗框本身将水引导到开口的每一端，在该开口的每一端都向下传播到雨屏腔的底部以排干。
   For many climates where the rain screen's main benefit is allowing the wall to dry to the exterior, rather than stopping bulk water intrusion, your detail is probably just fine. But it isn't as resilient an assembly as it would be with flashing.

   克雷格，
   There are several issues here, and Malcolm has touched on some of them. Of course the architectural drawings and specifications govern what needs to be done.

   Z-flashing is installed over the exterior head casing of windows for several reasons. One is to prevent water from dribbling down between the head casing and the sheathing, as you point out. Another is to keep water off the top of the casing so that the casing doesn't rot.

   您假设Boral不会腐烂或恶化，但是我们不知道这是真的。Boral由粉煤灰制成，这是煤炭燃烧的副产品。这是一种相对较新的产品，其往绩有限。我们真的不知道多年来暴露于天气时会如何保持。因此，我与建筑师一起投票 - 外部套管需要通过Z-Flashing保护。

   Martin... in 2015 you wrote "[Boral] is a relatively new product with a limited track record. We don't really know how it's going to hold up when exposed to the weather for years."

   您在2018年会说什么？
