Cedar fence pickets as cladding?
马克斯·E| Posted inGeneral Questionson
Hi
I want to install open joint siding on the house I’m building.
目标是水平板，超过1×4条带。每个板之间的1/8间隙。房子需要能够在潮湿时积极地干燥。
I can buy western red cedar fence planks in 8 ft lengths for about the same price as lp smartside or hardie board.
2 questions – 1.is there any reason at all that cedar pickets would not be a good idea?
2.智能侧壁或Hardie板是否会在本申请中更好？
The boards will be painted, regardless of which option we decide on.

Tell us about how you will keep the rain water out of your walls with such large gaps?
你会依靠单一的水束缚层吗？UV光线如何通过差距影响这一层？
Will you have a large air gap behind the board to aid in drying?
你能处理黄蜂和其他昆虫的事实吗？
如果成本是一样的，它似乎是一个糟糕的选择。我想你应该能够少得少，如果你想要的样子，愿意每隔几年愿意重新粉地，那就能够少得多。
Most barns use vertical siding as you describe and hold up well.

I won't keep the rain water out of the walls. A little will get in but if Joe lstiburek is to be believed open joint systems generally work better than non open joint.
There will be a .75" air gap behind the siding.
I will have two layers of web behind the siding.
No direct sunlight can get to wrb through a 1/8 gap. and very little reflected sunlight
Can you expound on why it seems like a poor choice compared to hardie?
Thanks
最大限度，
Can you link to Joe's comments on open-cladding?
Research by RDH shows that rather than a little bulk water penetrating gapped-cladding and hitting the WRB, quite a lot does. To me that means the cladding becomes largely aesthetic, and the WRB takes on the role usually assumed by cladding - dealing with wetting and drying further into the wall, where the assembly is more vulnerable.
通风雨屏是建立良好的墙壁组件，其中包层作为第一层保护，允许WRB和腔处理残留量的散装水侵入，并允许从外部和内部干燥。如果您需要比可以提供的更积极的干燥，我建议需要寻址的墙壁组件可能出现问题。
I have done this with horizontal cedar boards (1x3). With horizontal boards a lot less water makes it behind but still way more than regular siding. You have to be diligent with your WRB details and you must use a UV stable WRB (ie AirOutshield UV or RevealShield SA). Make sure the product you pick is also vapor permeable. Be careful as there are a lot of UV stable products for roofing that are vapor barriers.
如果你不介意更多的Maitanace沿着道路，你也可以使用与水的水（可渗透的）室外黑色涂料占据了Tyvek。首先进行粘附测试以确保它粘，不会剥离。
Thanks for this info. I was going to do what Eric reinholt of 30x40 design studio did- tar paper. But two layers. Actually, that's what I'm doing regardless ,as the tar paper on my 33 yr old house looked almost brand new when we changed windows last year-and this was with t1-11 siding right against the tar paper.
Hi Max,
Years ago I was looking into an open joint cladding system. They are awesome from an aesthetics perspective. I personally am not opposed to them in theory, as long as they're done correctly, however I've never done one and don't have personal experience so anything I say should be taken with a grain of salt.
I'm sure you know this, but for the sake of progression of thought: typically, cladding is meant to shed the bulk water, and then the wrb is meant to handle the small amounts of water that may or may not get through. It's a pretty good system, it has two layers of control to account for failures. (I live up north and like to do exterior rockwool between the wrb and cladding, which adds another layer of water management).
然而，开放联合包层系统主要用于审美目的。在下面的组件，在良好的实践中，仍然有2层系统的散装水+紫外线和小水管理。它们专门用于打开的接头系统，为黑色和紫外线耐抗保护背面的特殊WRB。它们比你的硬件商店tyvek非常敏捷。如果您要做一个开放的联合系统，我会建议在董事会下面。
至于您的问题：
1. Cedar boards can work, they're dimensionally more stable than Hardie, but they'll certainly require maintenance to keep them up to snuff. Just like any ol' fence they're susceptible to greying and checking. I just had a neighbours fence board fly off their fence from a wind storm and smash a skylight at my build.
2. Hardie在与他们的技术团队交谈时，我的知识并非设计在他们背面的批量水。他们的防水层是涂料。你可能会和他们一起获得早期失败。我用水和冻结/解冻的东西做了一堆个人撕裂。聪明的一面我没有经验，但昨天正在看他们的网站。我不认为他们有直木板吗？他们的系统是为了圈子壁板，我认为如果你差距，我认为看起来很可怕。而且我确信他们的欧黛尼就会比想要在背后的欧洲织布机上的失败。你可以c的东西，并要求他们的技术团队。
Just some thoughts,
Jamie
谢谢你的绞尽。实际上我只希望打开的关节，所以房子可以干燥。我喜欢膝盖底板只是好，这里有一些评论让我真的重新思考这个开放的联合事物。
圈壁板可以看起来goo ooood

我发现乔的开放式评论。我认为他们有几件事是有问题的。
The first is his dismissal of the amount of water that penetrated the wall. RDH shows it isn't insignificant, whether or not the open-cladding dries at a rate higher than it allows wetting, you are still allowing too much wetting to occur.https://www.rdh.com/wp-content/uploads/2017/10/RDH-BSL-Drainage-Balance-Spray-Rack-Report.pdf
第二个是对落后的事情的含糊不清。他说，如果它将是可见的，并且持续很长时间，WRB需要美观上令人愉悦。但是，如果被要求停止散装水侵入，则避免在开口或紧固件周围详细说明它的问题。这与腔洞可以干的程度无关。您如何有效详细说明WRB以停止水进入墙壁？
这一切可能，并且可能会正常工作，但我可以看到的唯一原因是你想要出于美学原因的开放式包层。如果墙的性能是主要关注，我会选择此链接推荐的另一个更合适的组装：

This is VERY helpful information.i thank you. From the first link, it looks like the open joi t cladding with half inch gaps admitted quite a bit of water.
From the second link, it says wood dries by vapor movement from wet area to dry area. So with cedar maybe I don't even need a rain gap? Very interesting. This has me leaning more towards lap siding now. I like the look of lap siding and it would save a step if didn't have to install firring strips
第一的
THANKS!
最大限度，
对于几乎任何气候和墙壁组装，雨水屏的好处是值得额外的工作。
事实上是耐寒的木板赢得了标记战争，公众认为它是一个高级产品，与奇怪的可治区栏相比，将转售价值添加到家里。
我不是说，如果成本相等，那么低维护和转售价值会使耐性更好地选择更好的选择。
您可以在22.5°或45°处撕开电路板的边缘，以便水必须向上爬到山上进入墙壁。
If you are committed to this look, I bet you can find a local mill to supply the green wood that install tight will dry and leave the gap you want for a lot less money.

我可以理解它。维护胜利。几乎总是。
我想要打开关节只是为了假设的干燥能力。现在我在想常规圈壁板。我将研究Hardie Board的透气性。
哦，我也会寻找一个绿色雪松的供应商。谢谢你的建议
Thanks.
