If moisture was routinely buffered any further into the fabric of a domestic residence, that’s just too far and has not been addressed or controlled properly.

 

Seasonally, perhaps this is an acceptable swing, but day to day it should be the immediate room interior surfaces at most.

 

I dislike this approach, and am not afraid to say it!

 

Grab the heat and moisture, use it to better facilitate heat recovery, and get the MVHR in and running.

 

Tin hat time. 

 

 

Restricting moisture sorbing and release to the surface materials (Gypsum plaster boards) limits the positive benefits of stable indoor moisture levels that natural insulations can provide.  Not an issue with MVHR of course (unless there is a sustained power cut in winter with high occupancy) as this is artificially removed.

 

Personally, I'd rather not rely on a mechanical system to stay healthy indoors.  Horses for courses.  And I prefer my straw hat to tin foil 🙂

I've done both, woodcrete ICF is a good hydrophilic material I believe, but good airtightness and MVHR to capture any ventilation heat losses.

So no mechanical fans in kitchen / utility / bathrooms etc?
