我在佐治亚州，在粘土/砾石上，代码/媒体可以被描述为“传统”，而不是最低限度 - 但我没有理由您不应该调整我的网站计划：绝缘的单片平板。您可能需要一个受冻结的设计和更多的隔热材料，但是由于您可能不必处理白蚁（在这里检查员确实要注意），所以我认为这在设计中会更加直接。
The slab will have integrated color and the floor will be polished concrete, since you're interested in cost effectiveness.

Jack,
如果您在白蚁区域，并且想要一个超绝缘的基础，则可能无法使用泡沫。
That means you have to build a crawl space with very deep floor joists, so you can use blown-in fiberglass to insulate your floor.
马丁，too cold for termites around here :)
乔，我've considered some variant of a concrete slab, and I can see how they would be a good choice for Georgia. Since I live in a cold climate I need both to insulate the floor from cold, plus either put in a deep foundation to get below frost levels (expensive), or put foam wing panels around a shallow frost-protected foundation to stop the frost from getting underneath the slab (also expensive). What I was hoping was that there was a less expensive alternative that I had overlooked.
Jack,
超级绝缘的基础并不便宜。如果您想要高性能，可以建立绝缘的筏粉底 - 请参阅泡沫在基础下。
马丁，
Thanks for the link to your blog. I found two statements very interesting. First, by you --
And next by Kevin Dickson, MSME, P.E. --
(followed by the rationale)
如果您和Dickson的建议是正确的，那么也许有了适当的增强板，我就不必担心使用任何昂贵的外部泡沫绝缘材料！为什么不只是在平板顶部建造一个轻巧的框架地板，然后用较便宜的玻璃纤维或纤维素将其隔离。无需担心在混凝土中进行热桥接，因为它将在热包膜之外。您是否看到这种组装中的那些讨厌的意外问题？
Jack: I think we've all been where you are on this; groping for some kind of Grail. IMHO, skimp somewhere else, like using plywood for the kitchen/bath counter tops temporarily. You get one shot at a properly built foundation, and all the foam you can pour at it will likely pay for itself. If you put foam under the footers, make sure you read the fine print about what the compression factor is for various psi ratings. If you require 15 psi bearing, you may need "40 psi" foam to avoid "creep". You have to decide how much compression you can live with, and whether or not you want to push the elastic limits of the foam, then buy the foam accordingly.
马丁，你说：
"If you're in termite territory, and you want a superinsulated foundation, you probably can't use foam.
这意味着您必须建造一个具有非常深地板托梁的爬行空间，因此您可以使用吹入的玻璃纤维来隔离地板。”
Just recently, the rater I've been speaking with says inspectors are willing to "consider" some of the new termite-treated rigid foam (Preventol is the brand name). Another option may also be, he thinks, some of the covered "fast form" insulation like Michael Chandler has reviewed (FHB) such as "EnergyEdge" or "PerformGuard."
我f they're willing to do more than consider options, it could open the door to some new options.

乔，
感谢您分享好消息。对于我们这些白蚁线以北的我们这些人来说，很难通过在南方建造检查员来领先于当地裁决，因此我感谢该领域的听力信息。
马丁，
我确实住在白蚁地区（田纳西州东部），我正在建造一所房子，我非常担心白蚁。适当的基础细节是什么？如果我选择密封的爬网空间，可以将绝缘材料放入托梁中吗？我认为爬网空间和居住空间之间不应隔离。
我s a slab on grade with insulation below the better option? (Forgive me if this should be a new thread; please let me know and I'll start one.)
My comments above are useful only if you can find a PE who believes the soil under your house remains dry.
"In developing the Frost Free Foundation solution, SBRA engaged the services of Paul
Hayman, PE. Explaining the dynamics of frost heave, Hayman emphasized that ground heave can
仅当满足三个条件时才发生：土壤易感性，户外温度以下
freezing are sustained for long periods and the soil has sufficiently high moisture content.
Paul Hayman wrote the report, and could perhaps recommend an engineer in your jurisdiction. You'd have trouble convincing your building dept. without someone stamping it.
Jack, I don't think the slab/floor system you describe is cheaper than just an insulated slab. Remember, if you go with concrete as the finished floor, you are saving about $6/sq.ft.
大卫，
是的，可以在地板组件（爬网空间的天花板）中安装爬网空间绝缘，而不是墙壁 - 只要您生活在温暖的气候中，以防止管道冰冻。
