   嗨，乔 -

   First, you did not mention your weather-resistive barrier. Will that be located to the interior of the exterior rigid insulation? That is where I would locate the WRB in this assembly.

   其次，我希望我的覆层后面的空间 - 污染的金属或反向板以及板条 - 是真正的专用通风孔和免费的排水空间。对于这些覆层，这意味着水平面向的间隔者。这意味着切断的毛茸茸的条或纵横交错的毛茸茸的条或“蜂窝”制成的垫片。

   Peter

   Thanks Peter,

   正如您建议的那样，WRB将是刚性绝缘的内部。我是否正确理解您，因为您建议将水平带应用于Roxul（在这种情况下）以及附带的覆层？水平条不会捕获和吸收水，以至于瓦楞纸面板的自由排水垂直空间吗？似乎可以避免的巨大步骤，更不用说建立窗户和门的深度更少了。

   波纹金属壁板和反向板和板条作为雨屏的功能，并通过与背后的基板接触的腔体不到8％来满足我们的代码要求。这是没有（正如马丁所说的）矿物质羊毛的固有干燥和排水能力。

   反向板&板条更容易水分getting into the cavity than many other types of siding.

   Joe,
   我不同意彼得对此。半刚毛的矿物质羊毛自由排水 - 这是一种固有的排水良好和干燥的方法。问题不涉及需要更大的空间空间 - 问题涉及在矿物质羊毛上安装任何东西的困难，这很笨拙。

   If your installers have the right touch, it will work just fine.

   谢谢。

   I wonder just how "squishy" it is? Around here the minimum order for comfortboard is a pallet, so I better be sure it will work well.

   I imagine corrugated metal over this product is ideal, the large surface area of the metal panel might help it resist deflection into the Roxul. I would be using a heavy gauge deep corrugation so the panels are quite rigid.

   Are the corrugated panels rigid in both axes? The corrugated panels I’ve seen are always stiff in the axis parallel to the corrugations, and pretty floppy the other way. You don’t want a ripply look to your wall if the fastened parts of the corrugated panels squish into the mineral wool more than the rest of the panel.

   I’ve cut pieces of small galvanized pipe to make standoffs in the past. You put a fender washer on each end and thread a bolt all the way through with the pipe acting as a sleeve in the middle. The pipe then takes the compressive force of the bolt so that the soft material doesn’t squish. It works well, I’ve done this many times to mount heavy things (masts and signage) on soffits that don’t have enough structure to support anything else. The downside is it’s a lot of extra labor to install.

   Yes, floppy one direction but I would think the stiffness in the other direction would distribute the force enough to resist squishing the board. Hard saying not knowing. No way would I ever create pipe standoffs, waaaay too labor intensive.

   Joe,

   The problem isn't only that they are squishy (they are squishy enough to be compressed by 2x3 strapping) but also that they are not uniformly squishy. This is the bigger pain, need to adjust every screw to get things level or make standoff (like Bill suggests). Both labor intensive.

   我建议您获得一些在盒子商店中库存的刚性矿物质隔热材料，然后尝试建造墙壁部分。

   刚性在商业墙壁上效果很好，在商业墙壁上，墙板安装在Z栅格上，而不是直接在刚性绝缘上。

   Until the mineral wool folks get they product more consistent and cheaper, I would stick with other types of rigid insulation or go with a wall assembly that doesn't use exterior insulation.

   你好，

   DIYer here:
   I've used mineral wool board in two applications.

   首先，在带有PMFS的爬网空间中。由于矿物质羊毛是可渗透的，不受水分损伤，因此我在没有任何空气或水障碍的情况下使用它（当然是混凝土除外）。这里的其他人可能会不赞成，但我对在有条件的爬网空间中的负潜在负载气候区域中对这种方法非常有信心。它与PMF一起用于此应用程序。少量的挤压非常适合覆盖小残留的形式线等。我建议采用2层方法，以实现真正刺耳的气候。

   其次，与您的情况更相关，我用它来对现有结构进行重新填充灰泥维修，该结构的构建约为3.25英寸（1英寸XPS，疯狂的绑带和空气散发）。我能够使用2 3/8“ R-10产品（难以获得，现在我有很多过量），带有薄皮（某些绑带更像5/8“比3/4”）。它是一些工作要使皮带相对平坦。我无法想象在上面安装膝盖。灰泥的上面很糟糕，因为不可能将灰泥牛拉得足够紧，我不得不在上面使用愚蠢的灰泥补丁。皮带电报。我认为基本上不再存在排水距离。值得庆幸的是，这只是一个小补丁。如果我再次进行此类工作（目前，我正在使用废料泡沫绝缘材料我不得不处理没有差距的恐怖闪烁的地方，我会将灰泥包裹物直接放在矿物羊毛顶部，然后将电线直接固定在灰泥包裹上（没有间隙）。那时它可能会很好地灰泥。我没有考虑制作对峙，因为它不会对灰泥造成帮助。如果我打算做对象，我个人会考虑尝试使用PVC管道（1/2“ ??），然后弹出密尔沃基一手电池供电的小直径管道/管道切割器（<$ 200）。您可以以这种方式以轻快的速度进行PVC僵局。

   个人（这只是由Roxul产品的经验和收到木匠等关于排水间隙样式安装在舒适板上安装的木匠的意见的一种疾病意见），如果我曾经追求完整的壁板系统更换而不是小型维修，尤其是在需要提高整体壁r价值，我可能会使用每8'12'固定皮带或壁架的Comfortbatt来探讨Larsens的TJI风格（因为两个堆叠的comfortbatt的故事可能正在推动它）。便宜，更易于使用，更好地安装，卸下架子，臭臭，更易于渗透，壁板的标准钉子表面等。我知道那里有很多人（这个网站？，互联网博客？）在Larsen桁架中使用Comfortbatt。

   我认为波纹不会太多地隐藏非平板。您的制造商可能可以指导您涵盖什么偏差。我希望您不得不将皮带固定成固定的话。

   Good luck! I love the Roxul batts but the boards seem like they offer challenges for siding.
