Can I use the moisture resistant version of a board and still achieve the same performance?

Where moisture resistance is required in a British Gypsum partition, lining or ceiling, the moisture-resistant version of a board, in the same thickness as the original specification, can be used without impacting the system performance. For instance, a Gyproc Soundbloc 15mm MR is equivalent to a Gyproc Soundbloc 15mm.
