I've now started putting on my dryline boxes, in readiness for plastering.
This guide

shows how to put the boxes into simple plasterboard. But I have polyfoam board. So it seems that I need to make a clearance in the insualtion for the tabs to return to the rear face of the plasterboard. I can see what I need to do. But it looks horrendously fiddly. Can anyone recommend a smart method of doing this?Cheers
