Hi all,
Due to the lack of ventilation under my subfloor, I decided to add some retrospective ventilation ducts behind kitchen units above the outside floor level. however after a few weeks I’ve pull the subfloor up and noticed the duct opening under the floor is soaking wet which I assume is condensation.
The insulation around the duct between the duct and joist is soaked too.
I understand I need to insulate the duct above the subfloor but I am not sure why the duct is so wet below the subfloor.
Please advise as I can’t fit my new kitchen until it’s resolved and it’s causing huge pressure on me.
