Another question about reveals.
We have 1930s house with 50mm cavity. The windows openings are closed with brick on the side of the window with gaps on top and bottom. The bottom gap has just a wooden window board over it, top gap has a wooden lintel above.
Plasterer has closed the reveals with plasterboard. He's first put some cavity closers on the top (which I insisted on - he was going to use roll of rockwool). He's then used 12.5mm and plasterboard to level off the reveal on top around the lintel with some battens in between to hold it in place. Is that good enough? I am specifically thinking about things like cold bridging as we are having cavity walls filled with beads. Nothing was done with cavity opening on the bottom (although I guess that'll be filled with beads to the board)
