Insulation/Spray Foam

[timmymac24]

I did what strousek did here in zone 5 after a lightning strike and attic fire in April 2024. We did spray and batt combo in exterior walls. The best improvement was having sill areas in basement sprayed that made a huge improvement. 2/3 of my Morton building has spray on the interior roof along with radiant floor heat. I keep it set at 55 in there and it's pretty efficient for the space that gets heated.

In the process of working this same issue out. The foam guy I got a price from said for our area the minimum he'd spray on walls was 3". Said that get it past the minimum R value for code and past any point he's seen with condensation within walls. Believe I'll do that and have the roof blown in.

I was told $1.35/SF per inch of thickness for closed cell

side note: apparently 300 is the magic # to become a WKR!!! nice...

This is for roughly 1850sq/ft living, 12' ceilings living/kitchen, 9ft ceilings everywhere else. Floor because it's a raised house on pilings.
I just asked for a spray foam quote and didn't specify any thickness or type and this is what they quoted.
