What type of spray foam?
« on: May 29, 2015, 07:58:42 PM »
So I've decided to give my NC-175 one last shot before replacing it, albeit with one change. I plan on replacing the batt insulation with spray foam insulation. Any suggestions on what type of foam I should use?
Thanks.

3" will give you greater compression strength. It will take the place of the outer "black sleeve" others use.
Higher R value too of course.

I've been looking at the same thing. Closed cell is def the way to go however can you get closed cell to install yourself somewhere? Seem like the DOW Froth Pak's are 200sqft of 1" thick and are $300! Are they even closed cell? Seems like 3" of spray foam could cost you $600+ to insulate...????

Yup, it's not cheap.
