So i have a steal beam (supporting wall for the first and eventually loft) going through my new ground floor bathroom.
BC have specified the beam be boxed in fire rated plasterboard (pink). No problems.
Given that its in a bathroom, the walls all have moisture resistant plasterboard(green).
Should the boxing around the beam be layered in pink then green?
or does one of the two negate the need for the second?
I haven't asked bc this, but i assume from their view as long as pink is over the beam, the rest is between me and the builder?
