Window rough openings and raw edges exposed to multiple rainstorms: Is this a problem?
I have a Zip-R sheathed house that is still in framing. The window rough openings have been unprotected for two weeks now and several hard, heavy rains have poured down on these rough openings, saturating the raw OSB edges and foam. The windows are scheduled to be installed in a few days. I tried my best to get my builder and his crew to flash these windows ASAP after sheathing them, but I was unsuccessful. I would’ve preferred it be protected from the beginning.
My questions are:
1) How big of a problem is it for these areas to get soaking wet multiple times?
2) Should the framers have already flashed the sills, immediately after sheathing around the openings?
3）木材是否需要在安装窗户之前完全干燥？
谢谢！

First advice: since your builder created this issue, have him/her get the answers to your questions. Have him call the manufacturer of the materials and ask them the same questions you are asking here.
Also get him/her to take moisture measurements (pin type moisture meter) of the wetted materials, commit to drying out the house such that the moisture level is below 15%, and then he/she can complete their work.
您的建筑商是否应该在施工期间保护窗户开口？我知道重塑与新结构有所不同，但是：当我是建造者/改建器时，我不必担心的建筑物的粗糙框架的常规润湿。但是，当我知道这将真正锤击建筑物时，或者在活动期间很明显建筑物将被敲打 - 我将我的屁股拖到工作地点并保护了建筑物。
Intense wetting often means intense drying is required. And what I worry about most is NOT the exposed surfaces that are easily assessed, but the buried places moisture can remain a very long time (such as underneath wall bottom plates/structural subfloor). See attached photo: 9-inch rainstorm hit this model home under construction several years ago in July. More than 3 weeks later moisture reading in all exposed OSB and framing were in the 12% range. But the bottom side of the bottom plate and the topside of the floor OSB: 27.5% moisture content by weight--REALLY wet.

说得通。我绝对担心下一步之前的干燥能力。他们计划使用拉链拉伸胶带。我在录音之前发射了足够的发射。恐怕Zip-r泡沫窗台会阻碍干燥。是Polyiso的1英寸。正常的OSB将干燥Easikynin这两个方向。
Clayton,
如果我们没有在雨中帧be no buildings in British Columbia. The main concern isn't the wetting, as Peter pointed out, it's making sure things are dry before encapsulating them.
您认为封装Zip-R的是什么？石膏板？还是简单地将粗糙的jam和窗台涂上胶带？
检查OSB边缘的肿胀。
I did and I have a little bit of swelling.
肿胀不好，但是如果要干燥，它可能不是世界的尽头。结构完整性受到损害，但我不认为OSB边缘有很多结构负载。
I was surprised at little water zip sheeting would absorb. I made paths thru the mud around the house and to the burn pile, months later when I pick up the Zip it seemed unaffected.
Huber company make Zip sheeting biggest product AdvanTech subfloor this products claim to fame is how well it stands up to being wet for weeks on end. My point is there strand board products do stand up to water well.
I encourage you to find a small scrap of the Zip put it in a bucket of water with a brick on top of the Zip, pull it out after a week.
我认为，一旦表面干燥，胶带/闪烁粘在绿色的脸上就不会有任何问题。

听起来还不错。谢谢你。我会去做的！
