Rigid Foam

I think we don't need rigid foam when using an inner airchamber/rainscreen. In the above pictures, rigid foam is shown.


If we do decide to use rigid foam, we could use 1" CodBoard 

CodeBoard

http://insulation.owenscorning.ca/builders/products/codebord.aspx#:~:text=CodeBord%C2%AE%20insulation%20is%20GREENGUARD,%C2%AE%20insulation%20with%20shiplapped%20edges.
