What do you think of hemp block insulation?

I just came across a video about building with hemp blocks. Does anybody here have any insights or knowledge about it?
Hemp insulation is an excellent and very sustainable alternative to many types of more toxic building materials and insulations. But as for the hemp blocks, that would not be our preferred method.We’ve seen and looked into the blocks you are talking about, and while we like seeing innovative building products emerge, especially with natural materials like hemp, we would sooner use hemp batts. While the insulation in the blocks is natural, each block has a plastic form inside it which makes up the structure itself.
至于碳足迹，它们在制造过程中排放了相当高的温室气体。使用大麻块本质上意味着你正在建造一个塑料框架的房子，与大麻/石灰混合物绝缘，所以总的来说，它不像乍一看那么自然或“环保”的产品。在我们对这个产品的看法中，我们认为你会得到一个更可持续的，可能更实惠的墙组装使用麻巴特绝缘在一个标准的木框墙。Wood is a much more sustainable building product, not to mention that awood frame wall with hemp batt insulationmeans when the day comes where a house needs to be decommissioned, all the components are reusable or recyclable, where the hemp block will be of limited value as a block with a plastic frame inside. it.
这些观点都很有道理。那么HempBLOCK系统呢?看起来JustBioFiber产品在很多问题上都是免费的。
Interesting, I hadn't seen that one. Looks like a similar product just no plastic structure inside. What's your intended purpose for it?
I'd like to determine if it's a good alternative to building with ICF. It appears have many of the same benefits and maybe more DIY friendly, eco-friendly, pest resistant, etc. I'm still trying to find more info on finishing options, moisture control, below grade use, flooring systems, etc.
Not having worked with it we really aren't in a position to comment too much about it, but a few things to consider - they would not be airtight, so you would need an air barrier for sure. ICF is extremely airtight, that's one of its benefits. The down side of ICF in our opinion is less about the EPS foam and more about the carbon footprint of the concrete. If you were able to source carbon capture concrete that is one way to bring ICF right into the folds of 'green building'.
