Thanks @SBayer !
I’m glad you enjoyed the presentation on PH Accelerator! Great questions 
I do think you are right, mineral wool seems like a logical winner, but they really need to decarbonize their manufacturing process. It just irks me that so many people blindly back mineral wool when it is not the most carbon friendly insulation product right now… and if we are trying to reduce embodied now, are we doing ourselves a disservice by blindly spec’ing it on every project.
