I currently building an addition and plan on putting up a knotty pine tongue and groove (1×6, 3/4″ thick) ceiling attached to the bottom of scissors trusses. The trusses are 24″ on center. I plan on putting up 5/8″ drywall first to get an airtight assembly. The tongue and groove pine is end matched (ends are tongue and groove as well). My question is this, with the drywall up, am I ok not ending each piece of pine on a truss seeing that the ends are also tongue and groove, or am I asking for trouble if the boards aren’t nailed on the ends?
