Hi folks, a question for those of you who have a timber I-beam dwelling.
Where an internal stud wall abuts an external I-beam wall sheathed with 12.5mm smartply, does the external wall require reinforcement with a noggin of some sort to take the fixings from the stud wall? Or is the smartply sufficient on its own to take the fixings? (The I-beams in the external wall are at 600 centres.)
