chipboard or rough pine boards for subflooring??

[vagabondo]

Hello!

I need to fill an area in the house of about 2 square meters with new subfloor and I'm wondering what is most suitable. The rest of the house has 17mm tongue and groove flooring, but that's much harder than what's available to buy today, hence the hesitation. I've seen chipboard flooring available in 17mm thickness, which fits since the floor needs to be at the same height as the old, but is it stable enough? What would you choose?

Counter-question... what are you going to put on top of the subfloor?

One more counter-question... how far apart are the floor joists?

1. it will be parquet
2. the joists are 30cm cc
It's about a former storage room that we have converted into a passage (small hallway) where there has never been a proper floor.

on a cc 300, I would think that you could nail anything without the floor becoming wobbly. If the floor joists are not that thick, you can add nogging to increase stability. But the simplest is, of course, to lay chipboard. Personally, I would probably lay raw wood planks if the rest of the house has it.
