No not really, so when you say lumber is that plasterboard, I want to make sure I get the right materials.That would be the studs - a.k.a. dimensional lumber, a.k.a. 2x4s, 2x6s, etc. The drywall just covers up the studs.
But reading my answer, I must have misunderstood your question as stated. :sweat:
Is drywall a specialist thing?
