I'm having a problem getting my screws into the joists. The PB is 9.5mm and there is 50mm Xtratherm insulation above it so I wanted screws that would go about 20mm into the joists - therefore 80mm long was needed. The nearest to this that I could find were "Eastdrive BZP Fine Thread Drywall 100mm" but they won't go right into the joists but leave about 20mm sticking out below the PB. Am I using the wrong screws? If so can anyone please advise on a better screw? (Using a DeWalt 18v screwdriver)
