I'd like to board the ceiling on top of the joists to provide some storage space, nothing too heavy, currently it's used for empty boxes etc. Would the joists support this weight (plus a person) or do I need to add more joists? I've never worried about this in the loft, I'm not sure why I'm worrying about the garage.
I'm also going to somehow board underneath the joists (plasterboard whatever - not decided yet) with insulation in the gap. Then the pitched roof will get insulated, but I'm getting ahead of myself.
There's also a total of 4 planks running diagonally across the top of the joists, assuming they're there to stop the joists spreading I can do away with these once the flooring is screwed down?
If it means the difference between putting extra joists in and not I'd be willing to spend more money on a more expensive flooring solution.
