A few question about my build.
我正在北卡罗来纳州梅肯市7或7a的梅肯市建造我们的退休之家。我们一直在与我们的建筑师合作，他很棒，并做了我在纸上提出的所有疯狂。因此，这是我们观看了几场建筑表演并看到他们做了什么并将其应用于我们房屋后提出的一切清单。
爬行太空基金会 - 福克斯块
crawl space pad – 2″ of ips foam under 4″ of concrete pad with vapor barrier coming 18″ up wall glued down.
经过EPDM橡胶垫圈的正常压力处理的窗台板（橡胶，因为我已经看到塑料粉红色泡沫的分解非常快。）
2×6 wall construction with board and batten siding on top of ( considering) zip r-6.6 sheathing, with 2″ of CCF followed up by 3.5″ or r15 rockwool. This should net a r-value of 33 on walls. I have been considering plywood with 3″ of rigid foam board since the floor joists according to my engineer seem to be cantilevered over the foam of the fox blocks.
Roof has 7/16″ zip with 2″ of IPS foam and then Carlisle WIP300ht peel and stick, followed up by 3/4″ battens laid at 45 deg. for Steel standing seam roof panels.
由于爬行空间和阁楼都是条件空间，因此无通的拱腹。
Am I missing any thing you could or would suggest. Is there something that would be poor design on my part and cause issues down the road? Attached is a picture of the wall section for my house. Everyone I have talked to here says man that’s over kill, I am working toward being very energy efficient as I hope to be running off just solar, and wind in the future here.
感谢您的任何帮助，您可以提供。

乔治，
Macon, North Carolina, is in CZ4. (See here for more info://m.etiketa4.com/article/climate-zone-map-including-canada）。On the wall, you don't need the two inches of closed cell if you are already installing ZIP R-6. I'd save some money and just install rockwool or another air permeable type of insulation in the wall cavity. In the crawlspace, I'd go with a thinner (two inch) rat slab and use the saving to install a couple of inches of rigid foam on the walls.
On the roof, are you planning to install insulation above and below the sheathing? If only above, you need a much thicker layer to get to R-49. (See here for more info://m.etiketa4.com/article/how-to-install-rigid-foam-on-top-of-roof-sheathing）。
史蒂夫（Steve），对不起，我忘记了我计划5.5英寸的CCF内部的CCF的阁楼，我在上面绘制的所有内容中提到的所有内容。我选择CCF 2“ ccf的原因是帮助密封任何空气侵入，以及填缝窗台板和底部板。我宁愿带有过滤的空气，而不是空气交换单元，而不是通过充满灰尘的空腔来进行空气奔跑。试图使我尽可能紧。我们有一个房屋绘制了一个3200平方英尺的牧场主，并在上面完成了工程，并获得了40万至80万的报价来建造它。耗材的报价为260k ..所以我们将大小调整为2200平方英尺的选秀权，以建造一个仍然适合我们需求的房屋
对于新的结构，您设计的喷雾泡沫不进去。它很昂贵，而且环保不太友好。有更简单，更便宜，更简单的空气密封方式。胶带的增加的成本很少，并且有一点护理，很容易获得被动房屋紧密度的房屋。
Your drawings show a vented roof but your description is for an unvented one. If unvented, the peel and stick should go above the deck, this way it can serve as both air and vapor barrier. Plus you won't need the fancy HT version, the cheapest non-granular one works just as well. You can use regular synthetic underlayment above the foam under the metal.
我已经看到了45度的束缚，但是除非您在深雪乡村，否则我看不到它的功能。大多数金属屋顶面板都有足够的肋骨和条纹，可以提供足够的气流，以使那里的任何冷凝水都可以干燥。我将保持垂直束缚并简化您的安装。还要检查您的屋顶面板的额定设备，而不是全部。
You will need to tie the roof air barrier and sheathing air barrier together somehow. With rafter tails, this is one of the few areas best done with spray foam. One of the larger two part kits can do your rim joists and this area.
I'm confused about the picture you included. It doesn't match what you are describing. For example, it shows blown-in insulation on the attic floor, whereas you are talking about insulating at the roof. Is that what the architect proposed and you are wanting to do something different? What don't you like about R-60 on the attic floor?
是的，他的图纸需要进行调整。就在那时，我们对基金会进行了更改，并认为他刚开始时恢复了他的旧版本。但正如我所描述的。据我所知，有条件阁楼的整个想法是消除阁楼区域中的水分，并消除隔热层下的灰尘堆积。我的家人有时会过敏，而且我能做的任何事情都可以控制我想做的内部灰尘和灰尘转移。这就是为什么我关闭eve的原因，是的，它显示了山脊通风口，这也是错误的。护套上方的屋顶区域开放，用于在钢板下进行通风，以帮助更多的水分和冷凝水蒸发。
If you get the air sealing between the attic and the conditioned space right, there's no concern about dust in the attic affecting the occupants. And a vented attic is pretty much the best design there is for avoiding moisture problems.
乔治，
我认为，与经验丰富的建筑商合作，您了解如何建造高效健康的房屋，这将使您受益匪浅。您必须做正确的一千件事，房主几乎不可能监督这些细节。
