Hi all, I have a specific remodel case where it’s been determined that closed cell spray foam will be the most cost effective solution. In researching brands, it seems like the top brands include BASF, Natural Polymers (Owens Corning), and Huntsman. 

Is there a big difference in spray foam technology nowadays and should I lean towards finding an installer of a particular manufacturer, or is the playing field fairly even nowadays? Obviously every installer has touted their product’s technology and it’s hard to decipher from a neutral party.
