Renovating our 60s house and will soon start on the living room and kitchen where there is currently 17mm pine paneling on both the walls and ceiling. Initially considered applying gypsum directly on top of the paneling but realized I want to relocate some outlets, spotlights in the ceiling, etc. Since I'm down to the insulation, I might as well install a new vapor barrier (currently there is old aluminum paper) before OSB and gypsum. Since it seems impossible to find drywall screws shorter than 25mm (especially collated), there's a substantial risk of piercing the vapor barrier when screwing the gypsum (12mm) onto OSB (11mm) unless I install horizontal studs or battens between the vapor barrier and OSB. Framing horizontally with 45x45 is out of the question as the house is already tight.
The ceiling is not a problem; there I will install nail battens cc30 and then single gypsum.
Does anyone have any suggestions? Can't be the first time this has been done. I have considered these options myself.
- Install 12mm vertical battens on all studs (on top of vapor barrier) and then screw OSB with 45mm screws through the battens into the studs.
- Buy 15mm OSB and then attach gypsum with 25mm screws. Expensive!!!
- Buy a higher quality vapor barrier (like woven) and gamble on the 25mm screws not piercing the vapor barrier.
