Another Spray Foam Insulation Question

[mrmeaner]

I have a 40x50x14 welded frame metal building/shop. It is bricked on three side due to HOA rules. Anyway I had the entire inside sprayed with closed cell foam and painted came out very nice and made a hug difference.

I will be framing half of the building 20x50x10 which will include a bathroom, game room, tv room basically a pool house for our family

Once the pool house side is stick framed I was planning on directly spraying 3-4" of open cell directly to the closed cell. Then the wall down the middle of the shop will just have spray foam in-between the studs.

Question, might be dumb but, is this going to be ok since the foam will not but "in the studs" on the three exterior walls rather behind the studs?

Do you really need more than the closed cell in Lubbock? And yes, the insulation is better without the studs interrupting it. Studs don't insulate as well as foam.

Not a problem. The insulation has a higher r-value than do the studs so having it behind the 2nd set of studs will be to your advantage.
