Is this battening sufficient?

[RachelGodfrey]

Hi all,

I'm battening the walls of my brick and block 80s house, insulating in between and then plasterboarding over with acoustic plasterboard (heavier than the regular stuff). Have I used enough battens to support the weight? I see some people put header battens and noggins in too. I'm trying to do a thorough job but don't want to waste materials, plus the neighbours are very bothered by the sds drilling into the walls so don't want to go overboard.

Most walls are 2.4m high but some areas on the stairs are up to 3.3m.

600mm centres is fine

Looks a great job. You might want to add some across the top to minimise the chance of plaster cracking, but that's belt and braces.

Thanks all! Added top, bottom and middle noggins for good measure.
