Hi,

I have the next build-up with water repellent and foil faced PIR in both sides modelled as vapor retarder (sd=1500).

is it right?

Evaluating the WC in the PIR I have observed irregular, non-periodic changes in the total water content what makes me think that something can be wrong in the results. any thoughts about this change in trend?

However there are no larger differences in balances as it can also be recognized in part by the total
