我的名字是丹尼尔，我有一个关于我可能拥有的选项，以便在一年前在我购买的家中购买窗台衣架和地板之间的衣服。我位于5A区，AAALOST ZOTE 6A。我的房子是一个罢工地下室的一个故事，建在60年代后期。短期目标是提高能源效率，中期目标是用辐射地板加热取代现有的养老柜加热，长期目标是完成地下室并使其调节空间/可居住。

在GBA（其中有一吨的GBA（其中有很多天来说，这足以让我的头部旋转），似乎是绝缘机架夹具的主要选择包括切割和密封刚性板绝缘或喷涂闭合电池泡沫绝缘和添加热屏障。如果与闭孔泡沫一起使用，那么继续沿着地下室壁的内侧继续进行意义。似乎有更多的选择在地板托梁之间绝缘，尽管我肯定喜欢使用矿物羊毛贝蒂的想法。

Unfortunately, I have a bit of an issue. The house is a modular home, and I don’t have ready access to either the sill joists or to between the floor joists (minus a handful of floor joists directly under the bathroom to accommodate piping / electrical, which are in a couple of the attached pictures). There is structural sheathing on the underside of the floor joists. I have some concerns about the structure of the house as it is (temporary, upside down, undersized floor jacks supporting the house; subfloor panels parallel to the joist runs; plenty of loud cracking / popping noises overhead and coming from the attached garage; wonkiness with joist span and OC spacing under bathroom to accommodate piping). So, I had a structural engineer come out and I am awaiting the report.

Operating under the assumption that I am advised that I cannot / should not remove the structural sheathing (which seems like a fair assumption), what are my options?

我f I can cut access holes on each end between each floor joist, then I suppose blown in cellulose could be used to fill the cavities between the floor joists, but that doesn’t address the sill joists. And even if I can get a big enough hole that spray foam could be applied against the sill joists and on down the foundation fall, would that be advisable with the wood sheathing sandwiched between the top of the foundation and the foam (see the non-fiberglass bay picture to see that the sheathing extends over the top of the foundation) and also buried in the foam where the hole wasn’t cut? Plus, it looks like there’s fiberglass insulation against most of the sill joists already, so I’d have to fish all that out as well. I’d also consider rigid board insulation on the interior of the foundation walls, but with the stamped texture, I suspect that would be subpar. Then again, if I wanted to spend a ton of money, I could go with digging and adding insulation on the exterior, which would insulate the foundation walls and the sill joist, and then it would just be a matter of blowing in cellulose between the floor joists. That would also save me a bit of a headache with the stairs by reducing the added interior thickness to the walls, but that would be _quite_ expensive I’m certain.

Anyway, I have gone round and round in my head for a while now, and done enough reading to work myself in circles, so I defer to the wisdom of the folks on GBA for insight and ideas.

非常感谢，此网站是一个惊人的资源。

Edit: As noted in my comment below:我今天收到了工程师的报告，他们提到了在基础墙壁和中心梁的18英寸的地板托梁下的移除将是可以接受的，而不会影响其结构益处“任何显着程度”。
