February 16, 20224 yr comment_24042 Hello, I have a doubts about the regulations contained in the Approved Document B. What is mean "Not be easily demountable " ? Is it allowed to have 30min fire rated grid ceiling (tiles) to meet this requirement? Or this must be a plasterboard ceiling ? Thank you in advance. Report
