That is causing me the issue here - the price of the intello is I think around 40% more, not inconsequential when you need a lot of the stuff. Then I was trying to understand the differences and if I really needed the intello. 

But it makes perfect sense that you would want any vapour out the walls and back into the house in summer to stop condensation in there, but I assume the VC foil just doesn't do that. Only intelligent VCL's do. It especially worries me as I have a SIPS build and interstitial condensation would be a major issue. But similalry...im pretty sure hardly anyone in SIPS is using an intelligent VCL. Are the sales tactics preying on my overthinking? 

 


I agree. The other factor is how much the MVHR effects the condensation content in the house. Are we worrying about something that is a non issues?
