We are looking to finish our basement next spring and one builder suggested using spray foam insulation as he says it's a good choice for insulating and sealing CMU basement walls and floor in northern California. We want to do this basement conversion as sustainably as possible with good air quality and there seem to be a lot of different spray foams available some of which mention climate change and environmental concerns - but we're wary of greenwashing, so I would value your opinion as to spray foam insulation in general for basement conversions and which spray foam would be best for environmental reasons to help us make a decent choice. Thanks!
