I've never put up PB before but it's a small (8ft x 6ft) back bedroom so I'm going to try to do it myself. I'd just like to know if there's anything I need to look out for. The roof slopes up from the eaves and I'm putting up PB with a 40mm insulation backing.
you don't usually put insulated plasterboard on a ceiling, But if you want to, use a cordless drill driver and 60mm screws, don't sink the screws too deep, just below the surface of the board,and get someone to help you
Thanks welsh brickie but now you've got me wondering if there's any particular reason that it's not good to use insulated PB for a ceiling? Or is it just that it's not usually done?
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)
