Thank you for your answer

I am using WUFI for a project of restoration and I meet exactly the same problem than the one submitted upper (Air layer 30cm). I just don’t know how to consider the phenomenon of convection in such large air layers and how to extrapolate µ and R values. The answer has been given in 2006 and there i...
