moisture vapor drive
could you direct me to the study that shows moisture vapor drive thru open cell foam at various thicknesses in the conditioned lid assembly?

..nothing heard.. i for one will continue to apply open cell conditioned lid assemblies @ 10" in cold climate zone 5 with out a vapor retarding paint or other membrane...i have done such for 15 years with no condensation failures..,, i have seen no formal paper to prove otherwise,, obviously if you apply short you will have a failed assembly,,same goes with closed cell,,even if you have a "vapor retarding memberane"depth of application...physics is physics,, |
