I am getting quotes for closed cell foam.
I've asked about varmit resistant additives and 1/2 the salespeople I've talked to haven't heard of it or just say it's not needed. Most people (end users) in rural areas say it's a must.
Another salesman stated there are more studs (16"oc) in a stick built wall thus uses less foam compared to a pole bldg. I told him I have 6 girts; 3)2x4, 2)2x6, 1)2x8. My posts are 8' on center. So for rough math 96"/16= 6 same number as the studs for a 8' length of wall. Now with my girts laying on their side they take up more foam space than the 2x4 studs would since they are on edge. I'm starting to think this whole up charge for pole barn corrugated tin is BS.
As far as you get what you pay for, I agree to an extent. The more I think about this corrugation and the space girts take up compared to studs it looks more and more its a wash.
The more I talk to these foam people, the more I get the feeling they are trying to get me to pay for the privilege of them ******* on my shoe and having them tell me it's just raining.
