What insulated plasterboard would you recommend? Vapour barrier or not. Built in vapour barrier? I want to make sure no condensation between tanking and insulation. Top 1 foot of walls are above ground. Was going to core 2 x6 inch vent holes to allow air flow between wall and rear of plasterboard. I also have 2x 6inch vent holes that allow cross flow ventilation via humidity control sensors..
