Hi

Guys hoping you can help

I want to smarted up my single garage, I will attempt to get the walls painted summertime but before that want to tackle the garage ceiling.

As you can see the wooden joints, trusses, what the best way to cover it, a few people have said go for plasterboard and them skim/paint it, which is fine but the garage does get very humid at times (70-90%)

What I don’t want is the plasterboard going damp, the warping then falling on my car and making a mess.

What other choice of materials can I use, chipboard, shower board, ?

Thanks

You could use the pink fire plasterboard. Tape joints and paint. Building regs say double layer standard board or 1 pink fire board. Your not under regs though so you can use what you want within reason. Think I would use a thin ply over and duck tape joints then overboard with pink fire plaster board Tape joints/fill screws and paint. The ply is to protect the back of board as you will be bunging stuff up there, and stop damp.. Others may suggest something else.

Thanks Wayners, would you suggest boarding on top of the joints, then pink plasterboard up on the joints, I wont be using it for storage or maybe insulate it with loft rock wool ?
My main concern is I dont want it all breaking and crashing down after a while with the damp, also will look install an air brick of some sort for ventilation in the garage for air circulation.

Also do i need to think about ventilation above the joints before everything is boarded up, as you can see from the pics there is no vents or air circulation (there will below the boarding though)
 
You could drop a few more timbers in and noggings. Be stronger and more support. Pink board will be fine.
 
Can anyone advise if its worth getting plasterboard with in the insulation built into it, ive seen ones which are 15mm thick, will this suffice or normal pink one be ok or even the foil backed one?

In my garage I have pink boards with chicken wire then rock wool. The chicken wire holds the rock wool after the fire has taken down the board. That's what I was told to do. Skimmed board and used that incandescent mastic around the edge.
