Insulation
Asked a question 4 months ago

Is there a general consensus as to if Spray Foam Insulation (Closed Cell) is a good product for permanent air sealing in a wood framed building? Can you direct me to documentation from non-manufacturers to make your case either way?

Where am I?

There are plenty of good solutions for permanent air sealing which are not Spray Foam Insulation. Here is a good article about why you should avoid Spray Foam as much as possible: https://foursevenfive.com/blog/is-foam-evil-a-new-paradigm-of-foam-less-is-more/32
