Spray Foam for basements, which of the different types are best environmentally?

我们打算在明年春天完成地下室的装修，一位建筑商建议使用喷雾泡沫隔热材料，他说这是加州北部CMU地下室墙壁和地板隔热和密封的好选择。我们希望以可持续的方式进行地下室改造，确保空气质量良好，目前似乎有很多不同的泡沫喷雾，其中一些提到了气候变化和环境问题——但我们对“绿色清洗”很谨慎，所以我很重视您的意见，即为地下室改造一般使用泡沫隔热喷雾，以及出于环境原因哪种泡沫喷雾最好，以帮助我们做出体面的选择。谢谢!
Insulating basements with spray foam is not uncommon, and in most cases works very well. A lot people like spray foamas an air barrier, a vapor barrier and for energy-efficiencyby reducing heat loss, as it has one of the highest per-inch r values of commercially available insulation products.
There are also some significantecological downsides to spray foam insulation, information about that (and the advantages - the ones with the newer more eco-friendly blowing agents) can be found at this page here, so have a look as it will likely answer most of your questions -
New HFO spray foam blowing make it over 1,000 times less harmful to the climate
新的喷雾泡沫产品出现的时间还不够长，还不足以让人真正了解它们的记录，但据制造商称，新的发泡剂的性能据说和你希望的一样好，甚至更好，它还应该导致更安全的室内空气质量。
There are some things that simply can’t be avoided that are definitely worth thinking about though, and that is that once spray foam has been applied to a substrate, like wood, it won’t be coming off. So unless someone invents a spray foam removal machine in the future, the current final destination of studs and sheathing covered in spray foam is none other than a landfill unfortunately as it won’t be able to be recycled. So, we love the new blowing agents, but we still limit the applications we recommend it for due to the inability to re-use or recycle it.
