   看起来比相当不错的好！

   可能有趣的辩论可能是玻璃纤维绝缘地板上方，上方没有在爬行空间地板上没有绝缘层。您所在地区的地面温度是多少，以及您对爬行空间的调节或脱离的计划是什么？

   蒂姆，

   As Charlie said, it's a better that Pretty Good assembly. Two layers of sheathing won't be cheap, but yield a very build-able and resilient wall.

   我分享查理也有关爬行空间绝缘的问题。当爬行空间没有调节和地板绝缘时，ICF基础的值丢失。

   墙上的性能double-studwall 12”of dense packed fiberglass is more than what would be necessary to hit PassiveHouse performance in a zone 4C climate. (Walls of similar construction & thickness have made it even in zone 6A type climates). Seriously, if taking the performance of the house to THAT level of thermal performance, buy the PassiveHouse design tools and tweak it for best bang/buck, or at the very least download and simulate with BeOpt. Even if you don't take the foundation insulation to PassiveHouse levels, you're probably better off going with a thinner studwall and spending the money on other aspects.

   基础墙下的XPS可能不会通过工程分析，即使它在爬行空间地板上没有连续绝缘的浪费也是如此。在你的上述墙上R，在2“大鼠平板下加入4”连续EPS将更有意义。如果基础墙需要从下面绝缘，它会在脚下进行，这将在更多区域上分配负载（并且可以通过工程分析调整以适应脚宽），其中2.5英寸II型EPS侧面和顶部脚踏实于其符合ICF泡沫，并且在2“温度下。

   - Charlie/Malcolm, the 5-year soil ground temp high and low (@8" depth) are 38.2 and 71.3. My understanding is that the fiberglass insulated floor (between floor joists) are not strictly needed. It was part of a belt and suspender approach and I have removed it from the updated detail (unnecessary cost). The crawl space will be kept under negative pressure with an continuous extraction fan with an Atmox monitoring system. Make up air will be provided by air from the above sub floor structure.

   - 谢谢达纳的彻底回复。很好的说明，关于基础墙下的XPS，我相应地删除了它。唉，成本考虑阻止我从事爬行空间地板的EPS和一只大鼠板块（希望我可以）。一般来说，我正在通过各种来源的许多良好的反馈，我试图在支出和收益之间找到甜蜜的位置。这第一个横截面可能比必须拥有更好。

   将很快发布更新的横截面，持续到60-40-20绝缘（Attic-Wall-Foundation），但在其他一些元素上承担。

   Thanks,

   蒂姆

   If cost is preventing you from insulate the rat slab, seriously run a BeOpt simulation. You can probably get more performance (better payback) out of a couple inches of EPS under the slab than the last 4" of dense packed fiberglass wall + sub-floor insulation above the crawl space.
