do you mean fixing stuff eg shelves,cabinets to the insulation backed plasterboard?I’ve got 25mm insulation backed plasterboard dabbed on my walls. This is mounted on grey “crumbly” blocks. What’s the best fixings and method for securing stuff to this please?
Where's the wooden batten in relation to the insulated PB? Behind it or on top of it?I think my issue is compounded by the fact that I am hammering home the plug, through a wooden battle mounted on the wall. This provides less control over the depth of the plug.
Should I perhaps drill to a depth which is 20-30mm less than the screw and then let the screw pierce the bottom of the plug and then int the crumbly block?
