Material to Install Between Foam Board and Wood Cladding
I had another post explaining that I am putting up cedar fence boards for wall cladding and just butting them together in my 7×10 office. My walls are insulated with cut and cobble foam boards (see pic) with a mixture of fiberglass faced polyiso, XPS, and EPS (all salvaged).
I expect the boards will separate a bit which is fine, even desireable, but I want it to be a dark color that is revealed. I had planned to put 1/2″ foam boards then paint those but I’m certain there is a simpler solution.
Options I’m considering:
Simply paint the foam insulation black w latex paint
Red rosin paper stapled over insulation (the red color is fine)
Roofing felt – I have a bunch of #30 but that’s probably too thick and not sure if I’ll be creating a moisture problem. Not too mention the smell on hot days but maybe that will dissipate quickly?
Open to other ideas. I’m aiming for simplicity.
