What’s the best way to insulate concrete basement walls? Does it matter whether the insulation goes on the inside or the outside?
There are several approaches to insulating the walls of a foundation or crawlspace, but a good place to start is with the International Residential Code (IRC). The most recent version, published in 2021, requires foundation insulation in climate zone 3 and up, although it’s always a good idea to check with local building officials for specifics in your area.
Insulation can be applied on either side of the foundation wall, and the code permits both continuous insulation (like rigid foam) and cavity insulation (such as fiberglass placed in a stud wall on the inside of the foundation). Code requirements are summarized inTable R402.1.3，但这里是基础：
- 气候区3：连续绝缘或腔隔热的R-5至少R-13。
- 气候区4，除海洋外：R-10在腔绝缘中的连续保温或R-13。
- All other zones: R-15 of continuous insulation, R-19 of cavity insulation, or a combination of R-13 in cavity insulation plus R-5 of continuous insulation.
这些是最低限度。如果你正在建造Passive House standards或者你喜欢的声音Pretty Good Houseapproach, you’ll have to adjust accordingly. Insulation will make the basement more comfortable. It also will lower heating bills, although estimates of exactly how much seem to vary from study to study.
在填充基础之前房屋正在建设中，井上的基础是绝缘的，或者在路上的改造之后。其中两个最常见的问题是使用的绝缘类型，以及内部或外部应用是否最有意义。
Before diving in, it pays to remember that insulating basement walls differs from insulating above-grade walls or the…

There is another option, commonly used in tilt-wall and pre-cast construction, where a layer of insulation is integrated between two continuous wythes of concrete which are connected by structural ties through the insulation. Thermomass (https://thermomass.com/products/system-cip/）是这种类型的系统的一个例子。如果这里有人在住宅地下室/地基上有这样的事情，我很好奇。
Hi Stuart, in residential (at least in my area) a similar approach is common with a concrete skin, insulation, and concrete "studs" in ready-made panels. Superior Walls is the most common:https://www.superiorwalls.com/
There’s a residential development in Newburyport, Massachusetts called
山坡可持续生活中心that uses a tilt-turn panelized wall system that was custom-fabricated by Blueprint Robotics. I’m not sold on the idea because of all the concrete but it’s noteworthy.
Thanks for the informative article. But I have to wonder, How can building this close to a water body be considered "green building"? From the picture it appears to be a virgin site. Where is this project located? Is there at least a silt fence and some type of erosion control somewhere hidden from view?
