I got a message about this job a short while ago. Fitting a suspended ceiling to help create a new music studio for one of my customers.
A fairly simple job. Fitted and bolted two supporting beams then used joist hangers to suspend the other timbers. All the bolts are in sheer (and there's plenty of them) making it a real strong job. I used large timbers so there would be no sag in the ceiling. Two rows of noggins gives the plasterboard full support at the edges as well so there should be no cracks.
Next we need to add loads (and I mean loads) of insulation ten board it with sounds deading plasterboard. I also need to add lots of fixing points in the ceiling so things can be hung from it if needed.
