I’m in the process of reconstructing an 1850s oak log house onto my early 1860s greek revival brick house in northeast Iowa. The building is being reconstructed onto the foundation of a portion of the brick house I took apart due to severe structural issues. Complicated, I know. The foundation of the brick part I disassembled and am rebuilding the log house onto has a basement under it. I did add a 5′ U shaped concrete extension to acheive the full 29′ of the new-old log building. The log building was 15″ narrower than the existing foundation, which left me with roughly an 8″ ledge on both the long ends of the log building. The old stone foundation was was roughly 2′ wide, which gave me plenty of room to build the new floor, log walls and new 2×4 walls onto. The new U shaped concrete pour extends 6″ beyond the ends of the logs on the gable end of the building. I studded up 2×4 walls on top of the 8″ foundation ledge and plan to insulate the cavity.

外部的塑料是暂时的 - 仅足以防止雪吹过这个冬天。

The front facade will be brick veneered with brick from the portion I took apart. The other two sides will be sided with smooth LP Smartside clapboard siding.

日志将暴露在内部。我计划使用罐装喷雾泡沫（例如100罐陶器很棒的东西；我知道愚蠢，但我不知道有另一种在课程之间发现喷雾的方法）来填补日志课程之间的区域。在日志课程之间的内部，我计划切割金属车床条并施加液压石灰daub。

我的隔离墙的计划涉及填充腔（大约6英寸至10英寸深，具体取决于对数表面的不规则性），并在纤维素中吹来。我将整个过程中整理1/2英寸OSB护套的一门课程，用纤维素填充腔体，添加第二个路线，填充腔体，然后重复直到到达墙壁的顶部。我的倾斜（暴露）阁楼天花板和山墙端的计划是3-4英寸的闭孔泡沫，其下方是R-21玻璃纤维。我计划在护套外安装Tyvek，1/2英寸的毛茸茸的条以及壁板上方。

鉴于前部将是砖砌的，我计划在原木墙上运行垂直毛茸茸的条，在松香纸上的主食，然后将2英寸的闭孔泡沫喷到纸上。砖贴面将绑回垂直的毛茸茸条，并且在砖贴面的背面和闭孔泡沫的背面之间将有1英寸的气隙。我将在砖墙的底部使用柳条绳。

新的原木部分以及现有的砖房的二楼将使用36k Fujitsu XLTH 3区热泵加热。原木建筑物的一楼将有一个12k楼层的单元，楼上的12k楼层单元，以及现有砖块的公共区域中的15k壁挂装置。我用Jotul F3加热砖房的一楼，并有一个全新的天然气炉作为备用。

我的问题是：

Does the wall profile seem ok? Beyond the spray foam between the log courses, there really isn’t an interior vapor barrier.

Should I be concerned about the cellulose near the bottoms of the walls? When I studded up the walls (that all hang out and away from the log walls), I used treated plates that cover the entire top of the foundation. So the cellulose shouldn’t be in contact with the top of the foundation. Should the bottom few inches of the cavity on top of the plates be sprayed with closed cell foam?

在门和窗口开口处，内部原木墙壁和外钉墙之间存在差距。计划是用1/2英寸的OSB桥接这些区域，以使纤维素固定在适当的位置。这似乎是合理的吗？

Other concerns?

谢谢您的帮助！保罗
