Hi. I was trying to put a 15 minute thermal barrrier over the top of these foam insulation panels. The front face of the boards are already covered with a thermal barrier, so all I have left to do is the top edges that face the ceiling. I took some 3/4" clear pine and went over the top and butted it to tight to the sill plate. My question is do I have to put another board over the butt joint at the sill plate board or can I just caulk this joint?
