Planning to lay flooring in the attic. Initially more as storage, but I'm considering turning it into a "loft" in the future. There's only headroom right in the middle.
I was wondering if anyone had any tips on how to get flooring that doesn't bounce without building upwards. The space between the rafters is 120 cm. If I lay 22 mm chipboard flooring - will it work, or will it flex too much without extra support? Any tips for reinforcing it if needed. I would prefer not to add additional joists between the rafters due to thermal bridges and there are lots of electrical wires running through.

I would prefer to increase the dimension.
There are lumber yards that have cheap flooring wood "ekonomigolv" in 28-32 mm thickness.
It becomes a bit more stable and much nicer!

If you're going to use it as a loft, shouldn't you have it heated then? (you are talking about thermal bridges?)
I would absolutely set the studs at c/c 600 if you're using 22 mm chipboard. Not fun if it sags in the future.
Can't you use joist hangers?

Would also have put up extra studs between, or studded the other way between the rafters to 600c/c, and laid chipboard flooring... BUT, there is another option, laying a 27 mm pine floor, works perfectly, laid it with 1000c/c without problems, try...
I had the same situation (although it will never be more than storage) and chose to put up studs.
If I were to do it again today, I would instead choose to increase the dimension of the floor,
because it was quite a hassle to set studs into the loose-fill insulation that I have.

I used 22mm råspont. Much easier to maneuver in the roof truss frameworks. Additionally, råspont handles moisture better than chipboard.
Does the floor flex?
Yes
Is it a problem for me?
Nah, not in the attic, it's like walking on a roof, which also flexes a little.
But I feel hesitant about chipboard flooring and cc1200, chipboards have somewhat unpleasant characteristics of cracking and not withstanding point loads.
