Hi,
I'm about to double board an RSJ with 15mm Fireboard as per the requirments of building control.
The issue I have is that one end of the RSJ is set onto the end of a wall that runs parallel and flush to the RSJ.
If I use the normal noggin method of fixing the fireboard, there will be a 30mm step at the end of the RSJ where the wall continues.
The exisiting wall isn't rendered or plastered. Should I, batten and plasterboard the wall to bring the level up (will be thin battens though) or just leave it to the platerer to make up the levels?
Any advice appreciated.
