有人在外部绝缘层上后面通风的硬迪圈壁板吗？
At this point we plan on building a 2×4 wall with dense pack cellulose (r-12), then 1/2″ plywood, 2 layers of 2″ fiber faced polyiso (r-26), WRB, 1×3 strapping and then siding. Can we use Hardie lap or Hardie panel siding? Likely a question for Hardie but they will likely say they want direct contact with sheathing and if foam, then no more than 1″ thick. Their install instructions imply direct contact with sheathing but I don’t see any restrictions against fastening to strapping….but maybe I missed that. Also, i’m guessing that strapping 1′ O.C. would make the most sense to reduce/eliminate deforming of the slightly floppy fiber-cement? Anyone done anything like this? Maybe this has been addressed but I didn’t find it when doing searches thru the QA section. Oh, and I would assume strapping desirable since wind blown rains will get behind the siding and it’ll never drain/dry if siding is tight to sheathing on a high-r-value wall…?
谢谢！

罗伯特，
Here is some information from Hardie:
http://www.jameshardie.com/pdf/ustb_2008_oregon_residential_specialty_code_code_mid-cycle_amendment.pdf
“当需要排水距离时，詹姆斯·哈迪（James Hardie）建议使用以下方法之一创建差距：
•使用毛茸茸的条（1/8英寸厚或更大）
•使用水电阻层增强了排水。”
http://www.jameshardie.com/pdf/install/install_panel-canada.pdf
“HardiePanel®壁板可以在毛茸茸的条上安装（根据本地建筑法规要求）。”
你们是最棒的！感谢您的快速响应。
我同意纤维水泥壁板可以是“软盘”
12英寸OC的毛茸茸可能过于杀伤...当间距为24英寸OC时，我看到了“波浪状”壁板
“底物中的警告瑕疵可以通过纤维水泥壁板进行电报”
约翰是对的，我曾经巩固了一个大型框架的项目，指出了PM的墙壁缺陷，被告知并列。壁板前看到的所有缺陷都很好地显示出来。
If your studs are 16" on center won't your furring need to be the same? - or am I missing something?
詹姆斯 - 我会将1x3毛茸茸的螺丝拧入泡沫4英寸后面的1/2“胶合板护套，当然，底部将有2倍的阻滞（插图到第一层泡沫），这将有助于消除向下拉动的拉力泡沫/毛茸茸/壁板取决于5英寸长的螺钉，否则可能会向下弯曲。我意识到螺丝螺丝拧入框架稍微有些更好，但是假设毛茸茸的频率（1'oc）会补偿加上补偿加上更好的壁板支撑。想法吗？
Hi Robert,
一个本地（明尼阿波利斯S）的项目最近完成了1倍毛茸茸的16英寸O.C的Hardie Lap安装。
我还没见过自站已经完整模型ted. Might be worth your while to swing by.

Thanks J- I didn't realize Tim's project used Hardie....I'll check it out.
罗伯特，
我认为即使您不希望撞到框架的地方，5英寸螺钉也不会足够长。这是一个经济的6英寸屋顶螺钉：http://www.bestmaterials.com/detail.aspx?ID=9221。笔记that they recommend a minimum 3/4" plywood for holding strength. Aim for framing wherever possible.
John B, that looks like a seismic X-brace that the contractor was hoping would be invisible.
我正在准备做几乎完全做OP的墙壁建造。我在Fastenmaster网站上找到了这一点：

现在，如果我能找到3/4英寸胶合板的特定重力。我正在考虑使用胶合板撕裂作为我的绑带以帮助避免分裂。我当然会很偏爱，但是我认为这可能是要走的路。
罗伯特，
你在哪个区域？如果您处于寒冷或非常寒冷的气候，则有许多原因由于许多原因而偏离Hardie。长期性能和产品问题是第一个……
那里有一个特殊的Hardie Lap壁板文档，专门指示安装人员在外部绝缘层安装其产品。IRC/IBC也这样做。
您将希望螺钉至少1.5英寸。这是行业标准.....查看Trufast Siptp螺钉。合理的成本和良好的性能。
布拉德，
If Robert hasn't finished the job by now he has bigger problems than which screws to use. His question is from 2012 :)
马尔科姆.....啊，是的，谢谢！
布拉德，
Even if it's too late to help Robert, your answer will be very useful for others with the same problem. I certainly enjoy all your posts!
Malcolm,
谢谢！
